Exosomes can Regenerate Your Stem Cells

Dr. Douglas J. Spiel gave a talk on how exosomes can regenerate your stem cells. In essence, this was at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas from Dec. 13 to 15th, 2019. His original topic was: “Placental MSC Exosomes for Longevity and Chronic Disease”. Notably, MSC stands for “mesenchymal stem cells”. Dr. Spiel recommended this website to look at applications of exosome therapy.

Essentially, what scientist found is that certain factors from stem cells can activate your own stem cells to regenerate tissues that grow old. These factors are messenger RNA (mRNA) and micro RNA (miRNA), which come as tiny particles of 40‐100 nm.

Advantages of administering exosomes

To emphasize, exosomes can be given systemically as infusion, and they can regenerate your stem cells, if they are in need of treatment. They cross the blood brain barrier, so it is possible to treat brain diseases. That is to say, there is no first-pass removal in the lungs as it is with mesenchymal stem cells (MSC). The potency is related to the age of the donor and his/her stem cells. Notably, exosomes are easy to store, freeze and administer.

Exosomes influence the growth of target cells and promote regeneration. In addition, exosomes stimulate immunomodulation and have anti-inflammatory and anti-fibrotic properties. To clarify, the only limitations are that the strength of the exosomes is related to the age of the blood donor. The exosome fraction comes from mesenchymal stem cells. That is to say, it circulates in the plasma portion of the blood, which is obtained by spinning blood cells down in a centrifuge. To emphasize, exosomes can regenerate your stem cells.

Applications of exosomes for various clinical conditions

Joint inflammation

Mesenchymal stem cells are useful to treat arthritis. But it is important to realize that exosomes from mesenchymal stem cells are doing the same by stimulating the body’s own stem cells situated in the joints. In fact, several target cells have been identified that are stimulated by exosomes. These are chondrocytes, chondrocyte progenitor cells, cartilage-derived stem cells and synovium‐resident multipotent progenitor cells. In addition, other target cells are osteoblasts and osteoclasts in resident MSC within the subchondral bone and chondrogenic cells in the knee joint.

Disc degeneration  

Degenerative intervertebral discs respond to exosome treatments. The IL1 beta cytokine is involved in intervertebral disc degeneration. Exosomes inactivate these cytokines and have antioxidant and anti-inflammatory effects. Exosomes are not all the same. Different sub-fractions were isolated that have anti-inflammatory, immune-stimulating, antioxidant and other effects on the body.

Aging research

Researchers were able to pinpoint aging to various factors that contribute to premature aging. To clarify, when there is a decrease of catabolic processes and an increase of anabolic processes, an older person can combat premature senescence. Another key point, aging is also linked to redox homeostasis. Simply put, oxygenation processes in the body need to be balanced by reduction processes. This keeps the body in a healthy state. ADP/NADH production can be stimulated by exosomes.

Longevity comes from good lifestyles

With the use of exosomes, the aging process slows down, as oxidative stress is neutralized, damaged mitochondria are removed and cellular debris as well. That is to say, this improves inflammation and premature aging.

As has been noted, in the past 200 years life expectancy has doubled in most countries. 4 areas where longevity is particularly common are: Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica and Loma Linda, USA. Only 7% of longevity stems from genetic factors, the rest is from lifestyles we adopt. In the final analysis, people who die prematurely followed a very poor lifestyle causing them to develop diseases, which ultimately killed them.

Clinical diseases from aging

Ultimately, advanced aging puts you at risk of getting cardiovascular disease (heart attacks and strokes), cancer and neurodegenerative diseases (Alzheimer’s disease, Parkinson’s disease). From the third decade onwards, there is the risk of bone loss, which causes osteoporosis. As has been noted, loss of cartilage causes osteoarthritis. Loss of muscle strength and muscle mass is called sarcopenia. With aging there is often an accumulation of abdominal fat. Hormones are disbalanced. Blood pressure is often elevated and blood lipids as well. Insulin resistance can develop and the blood vessels become stiffer. This causes heart attacks and strokes.

The details of the aging process are much more complicated than originally thought of. There is a combination of aging of the DNA, mitochondrial aging, stem cell exhaustion and a change of intercellular communication due to dysregulated endocrine signalling. In addition, there is a decline of the immune system and epigenetic factors that can turn off longevity genes.

Oxidative stress as a cause of premature aging

Dr. Spiel pointed out that reactive oxidative species (also known as free radicals) cause damage to mitochondria and mitochondrial DNA. But we need the energy from the mitochondria for a comfortable life. In essence, antioxidants can neutralize free radicals. Age-related conditions due to oxidative stress are: cardiovascular disease, chronic kidney disease and type 2 diabetes, chronic obstructive pulmonary disease, cancer, neurodegenerative disease, frailty and sarcopenia. Surely, both reactive oxygen and reactive nitrogen are free radicals. They have one or more unpaired electrons and all aerobic body cells produce them. Reactive oxygen and nitrogen species (RONS) cause oxidative damage to our cells and contribute to the development the diseases just mentioned.

Antioxidants help to prevent diseases

But antioxidants can contain these free radicals in various ways. The body has five built-in enzymatic ways to protect itself and five non-enzymatic ways (bilirubin, vitamin E, beta-carotene, albumin and uric acid). In addition, there are antioxidants that a person can take as supplements to inactivate RONS. These are: vitamin C and E; phenolic antioxidants like resveratrol, phenolic acids, flavonoids, oil lecithin, selenium, zinc and drugs like acetylcysteine.

Without control of the oxidative stress RONS can lead to cellular senescence and chronic inflammation. This leads to a vicious cycle where chronic oxidative stress and inflammation feed on each other leading to premature diseases.

Causation of several diseases

As we age, the body reduces the inborn antioxidant enzymes (superoxide dismutase and glutathione peroxidase). Before we can understand how to live longer, we need to be aware what happens in various health scenarios as follows.

  • The lack of inborn antioxidant enzymes leads to vascular endothelial dysfunction, high blood pressure and premature hardening of the arteries. This can become a precursor to heart attacks and strokes.
  • Elevated blood sugar in the case of type 2 diabetes leads to increased sugar concentration of body cells and formation of free radicals.
  • Oxidants from cigarette smoke activate macrophages and epithelial cells to produce inflammatory cytokines. Continued smoking releases proteases in the process that break down connective tissue and cause emphysema and COPD.

There are more diseases

  • Chronic kidney disease comes from oxidative stress affecting the filter units of the kidney, called glomeruli. With a lack of blood supply to the kidneys secondary high blood pressure develops and endothelial dysfunction. It also leads to chronic inflammation.
  • In the brain oxidative stress leads to cognitive impairment and dementia.
  • Oxidative stress and chronic inflammation are important ingredients for the development of cancer. RONS and cytokines release NF-kB, which activates cancer genes. RONS can also directly attack the DNA of cells and cause cancer through carcinogenesis.
  • Sarcopenia and frailty come from the action of RONS on the skeletal muscles. In old age there are less inborn antioxidants available. This leads to decreased muscle quantity or sarcopenia. Eventually frailty results with the risk of falls and fractures. 

Preventative measures for slowing the aging process

There is a number of steps that in combination help to slow the aging process.

  • A Mediterranean diet combined with a fasting mimicking diet or other calorie restricted diet
  • Regular physical activity
  • Cognitive training
  • Vitamin D3 supplementation
  • Reducing your risk to develop vascular disease
  • Certain drugs turn on the longevity gene (metformin, rifampin)
  • Spiel warned that due to limited compliance and variable response these steps alone may not be enough to prevent age-related problems

How to live longer

It is important to recognize the importance of antioxidants to counteract the development of these diseases. As already mentioned, the following counter the effect of free radicals: vitamin C and E; phenolic antioxidants like resveratrol, phenolic acids, flavonoids, oil lecithin, selenium, zinc and drugs like acetylcysteine. Mesenchymal stem cells can also stop the action of free radicals. In addition, exosomes, which  are products of mesenchymal stem cells can do the same. Mitochondria, the power houses within the cells, create energy, but also release free radicals. In his clinic Dr. Spiel administers intravenous exosomes to counter the oxidative stress. Numerous studies linked mitochondrial dysfunction to various age-related diseases. There are markers in blood tests that the physician can order to analyze malfunctions in the body. Dr. Spiel showed 4 slides that contained a lot of medical information that is too technical. I omitted it for this review.

Intravenous infusions of exosomes

The important thing to remember is that epigenetics can be changed by exosome infusion and lifestyle changes mentioned above. Dr. Spiel said that generally he uses 15 ml of exosomes by intravenous infusion every 12 weeks for longevity and performance enhancement. This treats conditions like infertility, osteoporosis, osteopenia, heart, liver and kidney weaknesses. Here is the dosing for intravenous exosomes by weight:

20-50 lb: 5 ml; 50-90 lb: 10ml; more than 90 lb: 15 ml; more than 220 lb: 20 ml. Unfortunately, one exosome treatment costs between 500.00 and 922.00 USD, an amount that most people cannot afford.

Contraindication to the use of stem cells or exosome therapy

It is important to realize that a person who has cancer should not receive either mesenchymal stem cells or exosomes. Indeed, exosomes do not differentiate between cancer cells and healthy cells, but stimulate cell division. For the same reason people with myeloproliferative disease (sickle cell anemia, bone marrow dysplasia) should also not receive exosomes. To clarify, other conditions where the physician will not order exosomes are primary pulmonary hypertension, acute bacterial infection or an immune-compromised state. In addition, macular degeneration with neovascularization is also a condition where the health professional does not administer exosomes.

Conclusion

Dr. Douglas J. Spiel gave a talk on how exosomes can regenerate your stem cells. Specifically, this was at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas from Dec. 13 to 15th, 2019. Dr. Spiel explained how disease processes age our organs. Reactive oxygen and nitrogen species (RONS) cause oxidative damage to our cells and contribute to the development of diseases. This involves the mitochondria in the cells as well. The good news is that a healthy lifestyle can counter these damaging processes to a certain extent. But it takes another step to re-establish the balance of our cells, exosome infusions. Exosomes are tiny particles that are shed by stem cells and that circulate in the blood. They can reenergize stem cells that are ailing to become functional again.

Expensive exosome infusions

He recommended an infusion with exosomes every 12 weeks for maintenance of good health and as a “fountain of youth”. Obviously, there are some limitations. As mentioned, it is not suitable for all patients, like cancer patients, patients with sickle cell anemia, acute bacterial infections or pulmonary hypertension. In addition, it is also not a treatment which many patients will seek out as the cost is prohibitive. One exosome treatment cost between 500.00 and 922.00 USD, an amount that most people cannot afford.

Can Longevity Research Make Us Age Slower?

Longevity research has done a lot of experiments, but can longevity research make us age slower?

This year an 800-page summary was published of all the longevity research that has been going on. A review of this research is in this abbreviated article. In the following I like to address some of the problems of anti-aging or longevity research.

Telomere lengthening

We know that people with longer telomeres live longer than people with short telomeres. When telomeres are longer, the cells can continue to divide and function normally. When telomeres shorten there comes a point when no more cell division is possible.  At this point the cell will normally be dissolved. When it persists, there is the danger that it undergoes a malignant transformation. This can cause premature deaths. On the other hand, if enough shortened telomeres accumulate in various organs, organ failure ensues. This will also result in premature deaths.

Research in humans has shown that increased physical activity elongate telomeres. So do vitamin C, E, vitamin D3 supplementation and resveratrol. A Mediterranean diet and marine omega-3 fatty acid supplementation elongate telomeres as well. In addition higher fiber intake, bioidentical estrogen in women and testosterone replacement in men can be effective in elongating telomeres. Finally, relaxation techniques like yoga and meditation are also elongating telomeres.

Antioxidants

Many processes lead to free radicals. Free radicals are unstable atoms that may damage cells and can cause illness and premature aging. Inflammation, the metabolism of our mitochondria, radiation exposure, industrial solvents and ozone are just some examples of what can cause free radicals in our system. If we have enough antioxidants on board, there is a balance between free radicals and antioxidants. No damage would occur then. In humans the two major antioxidants present are vitamin C and glutathione. Vitamin C comes from our food. Glutathione is produced by the liver and circulates in the blood. These two antioxidants are keeping free radicals in balance.

 

Anti-inflammatories

This Harvard site explains that even food can cause inflammation in us. For instance sugar, French fries, red meat and margarine cause free radicals. Anti-inflammatory foods are tomatoes, green leafy vegetables, olive oil, nuts, fatty fish, berries and fruit. A Mediterranean diet has anti-inflammatory qualities. There are 6 anti-inflammatory supplements that are useful to know about: ginger, fish oil, alpha-lipoic acid, curcumin, resveratrol and spirulina. In addition to the above, vitamin D3 also has anti-inflammatory effects in higher doses.

Chronic inflammation can cause cancer down the road, so it is important to prevent this by eating sufficient amounts of anti-inflammatory foods and supplements.

Genetic repairs

Spontaneous mutations of DNA, mutations of suppressor genes, oncogene activation and insufficient DNA damage response can all lead to cancer. In the past there was the hope of using chemotherapy and radiation therapy as a means to influence the outcome of cancer treatment. A reinvestigation of this concept is ongoing.

More specific treatment modalities are under investigation. When more cancer can be prevented and when it is possible to cure more cancers longevity in the population will increase. Cancer has been one of the major killers over the years.

Metformin research

Metformin has been in use for decades to prevent and treat diabetes. But beyond this it also has anti-cancer activity, it prevents Alzheimer’s, prevents cardiovascular disease and may be the first anti-aging drug. A trial to this effect is ongoing.

It makes sense that a drug that treats and prevents diabetes would be a longevity drug at the same time. The fact that it also helps to prevent cardiovascular disease and Alzheimer’s disease also makes sense. Anytime you remove a chronic disease, life expectancy improves. As a result metformin will likely receive approval as a longevity drug soon.

Mitochondrial repair

The mitochondria are small organelles in each cell. The purpose of this structure is to provide energy. In normal cells there are hundred of these organelles in each cell. In heart muscle cells, brain cells and liver cells there are thousands of mitochondria in each cell to provide energy. Muscles, nerve cells and liver cells require more energy to function properly.

Two supplements have been in use for some time to support mitochondria function.

  1. Co-Q10. This supplement supports mitochondrial function. It prevents heart disease, together with vit. K2 and vitamin D3 and it keeps blood vessels open.
  2. Pyrroloquinoline Quinone (PQQ). This supplement can increase the number of mitochondria in a cell. It can also improve their functioning. With aging we know that we are slowly losing mitochondria. It is important to know that there is a supplement that can counter the aging effect and prevent further mitochondrial loss.
Can Longevity Research Make Us Age Slower?

Can Longevity Research Make Us Age Slower?

Conclusion

For centuries people were hoping to live longer. Nowadays this dream seems to become a reality. But it does not happen with one magic pill. The aging process involves multiple targets that need attention. The telomere length is one factor. I listed a number of items that will elongate telomeres, like regular exercise and a Mediterranean diet. Antioxidants and anti-inflammatories are prolonging life as well. You want to preserve the function of your genes. Research is concentrating on improving gene repair.

Metformin has been found to prolong life. This molecule might be the first longevity drug. It has been in use to prevent and treat diabetes, but it also helps to prevent cardiovascular disease and Alzheimer’s disease. Two supplements help with mitochondrial repair, namely Co-Q10 and PQQ. Because life is all about energy, it is important to have well functioning mitochondria in all of your cells. When mitochondria are functioning, your body functions at its best, and you feel well.

Forget The Glass Of Red Wine For Good Health

We have been hearing for over 10 years that 1 glass of red wine per day for women and 2 glasses of red wine per day for men would be recommended in order to prevent a heart attack or a stroke. Now we are confronted with new research from Boston showing that even small amounts of alcohol are bad for you as alcohol is a carcinogen (=cancer producing substance). Misinformation like this occurs when science concentrates only on one angle of health, such as cardiovascular disease prevention and the other part of the equation, the cancer producing (carcinogenic) effect of alcohol, is disregarded.

In 1996 this Australian study followed 1236 men and 1569 women 60 years and over for more than 5 years and studied their mortality rates as a function of alcoholic drink intake. The authors found that there was a short-term protective effect with regard to cardiovascular/stroke mortality. But due to the fact that mortality was the end point for both cardiovascular disease and for cancer, the study was mostly taken as evidence that alcoholic beverages would protect to a certain degree from strokes and heart attacks. The authors were aware that alcohol was cancer causing as they stated, “Those taking any alcohol exhibited an increased proportion of deaths due to cancer at the expense of a reduced proportion of CHD and stroke deaths”. But this part was not mentioned in the popular press or in future alcohol/cardio-protective recommendations. The authors also were aware that the observation time of 5 years was on the short side. We know from other studies that alcohol toxicity requires a longer observation time such as 15 to 20 years or longer to show significance in a multitude of cancers.

Forget The Glass Of Red Wine For Good Health

Forget The Glass Of Red Wine For Good Health

As already mentioned above, recently a new survey of alcohol-caused cancer was published and went through the popular press. Dr. Timothy S. Naimi from Boston University Medical Center was the main investigator of an international team of scientists. The study found that every year 18,200 to 21,300 cancer deaths in the US (that is 3.2% to 3.7% of all US cancer deaths) are directly caused from alcohol consumption. The authors of the study determined that every person who dies from alcohol related causes lost on average approximately 18 years of his/her life (scientists call this “years of potential life lost”).  51% of women developed breast cancer from alcohol exposure, 62% of men came down with upper airway and esophageal cancers. Less than 1.5 drinks per day caused between 26% and 35% of alcohol-related cancer deaths. There was no safe lower margin. The authors concluded, “Reducing alcohol consumption is an important and underemphasized cancer prevention strategy”.

Interestingly, in 2006 other research looked at alcohol caused cancer cases in the world based on WHO data and came to the conclusion that with the increased worldwide consumption, particularly in East Asia, preventative steps by eliminating or replacing alcoholic drinks would be wise.

A recent study in 2012 where cancer rates in the US were compared between Hispanics and Caucasians showed that Hispanics had higher rates of stomach cancer, liver cancer, uterine/cervix cancer and gallbladder cancer. The authors concluded that Hispanics need more screening done such as Pap tests and that effective vaccines (like Gardasil) should be used. In addition effective interventions should be applied to reduce obesity, curtail alcohol consumption and reduce tobacco use.

Studies have shown that there is no safe level of alcohol consumption, not even the famous 1 drink for women and 2 drinks for men (with regard to heart attack prevention), because cancer incidence increases with increasing alcohol consumption in a linear relationship.

What does alcohol do in the body that it is so dangerous to your cells? Many cancer researchers have researched this question in detail. Essentially, alcohol is by itself a toxin for your cells (the targets being sub particles in your cells called microsomes and mitochondria). Your liver metabolizes alcohol into acetaldehyde, your kidneys excrete it and your lungs exhale it (this is how a breathalyzer can detect how much you have been drinking). All of these chemical changes in your cells release free radicals, which in turn attack other cells. This sets up a chronic inflammatory process, which breaks down your immune system, leads to cell mutations and finally to cancer.

What protects you from cancer?  It is the antioxidants that stabilize the above-mentioned processes: vitamin C, glutathione, vitamin D 3, curcumin, multiple vitamins, magnesium, flavonoid foods, cruciferous foods (like broccoli), exercise and soluble fiber.

So, if you were serious about cancer prevention, you may want to stop any alcohol intake and take the above supplements instead. The heart attack and stroke protection will be achieved by flavonoid foods (perhaps specifically adding resveratrol 250 mg per day as well) and exercise.

If you were less conscientious about cancer prevention, at least reduce your alcohol consumption perhaps to the occasional glass of wine or beer, but avoid high percentage spirits and remember, the less the better! You may be toasting to ill health with that glass of wine. Say no to false advertising of the wine industry! Your body will thank you for it.

Olive Oil No Magic Elixir

Health trends come and go, and some myths need to be demystified, such as the notion that we need a lot of one beneficial food to achieve good health. The Mediterranean diet has become a buzz word in the public, and there is certainly nothing wrong with a diet that emphasizes the benefits of vegetables and fish with omega-3 fatty oil. These figure prominently in foods of the Mediterranean. Olive oil, which is one of the fat sources, has been also touted as a “miracle food”, and the benefits of the healthy fats to which it belongs have received a lot of attention.
Dr. James Kenney, who holds a PhD in nutrition at the at the Pritikin Longevity Centre, questions inflated health claims of olive oil. No matter, which way you look at it, olive oil remains a calorie-dense and nutrient-poor food. Pound for pound, like all refined oils, olive oil has more than 4000 calories, and 13% to 14% of the calories in olive oil come from saturated fat. The good news is that compared to lard (38% saturated fat) and butter (63% saturated fat) olive oil is the better choice. People who switch from butter to olive oil will see a reduction of cholesterol, reports Dr. Kenney. The reason is that they are eliminating a lot of saturated fat, trans fat and cholesterol that was in the butter. Olive oil itself does not lower cholesterol, as monounsaturated fatty acids do not raise or lower cholesterol. As a result it is not a good idea to freely pour olive oil into salads, over vegetables or to dip white bread into it, transforming it into an oil-dripping calorie bomb.

Olive Oil No Magic Elixir

Olive Oil No Magic Elixir

Olive oil can be compared to rocked fuel: it is a high calorie food, and if you plan to go on a long distance bike excursion across the country, you’ll clearly need more fuel than if you are working at a sedentary job in an office. Olive oil should be used like salt. It is a condiment, and choosing extra virgin olive oil in a spray pump gives us a boost of flavor. The real beneficial food sources in the Mediterranean diet are fruit, vegetables, beans, small amounts of whole grain and omega-3 rich fish. Flavonoids and antioxidants in the fruit and vegetables are some of the main players, but lifestyle and genetics may also play a role.

Lycopene Benefits Backed By Science

Lately a lot of attention has been directed to the health benefits of vegetables and fruit. Vitamin C has long been an accepted household term, and nobody questions the benefits. Newer buzz words are the terms “bioflavonoids” and “antioxidants”. Some products are aggressively marketed extolling the above named beneficial substances, but often the consumer is left mildly bewildered by exaggerated claims. Often the sale prices of these miracle foods are as lofty as the bold statements that go along with them.
For any shopper it is important to know that some of the most beneficial foods are not high priced items, but very common staples. Take tomatoes, for instance. They are a significant source for the substance lycopene, which lately has received a lot of attention. Lycopene and its dietary sources as well as its benefits have been researched world wide, and the results are now in. It is responsible for the red color in fruit or vegetables, such as tomatoes, and its isomeric form 5-cis-lycopene is the most stable form having the highest antioxidant properties. Common dietary sources are tomatoes, watermelons, pink guava, pink grapefruit, papaya, apricot and other fruit. In the Western diet tomato-based foods account for about 85% of dietary sources of Lycopene. Studies have shown that lycopene is more efficiently absorbed from processed tomato products compared to raw tomatoes. Once it is absorbed it is distributed throughout the body. The highest levels showed up in the testes, the adrenal glands, prostate, breast and liver.
Research going back to 1995 showed an inverse relationship between the consumption of tomatoes and the risk of prostate cancer. A follow up publication in 1999 showed that the same inverse relation of lycopene intake and cancer also included breast, cervical, ovarian, liver and other organ sites. Further studies have followed these initial publications, and the great majority of them suggest that an increased intake of lycopene showed an association with a significant reduction in the risk of many cancers.
Coronary heart disease and lycopene benefits were also examined. The strongest population based evidence comes from a multi center case control study in Europe (EURAMIC). 662 Cases and 717 controls were recruited from 10 different European countries, and there was a significant relationship between levels of lycopene in fatty tissue and the risk of myocardial infarction. Lower lycopene levels were associated with a higher risk of heart attacks.Lycopene was also shown to decrease levels of oxidized LDL (LDL or low density lipoprotein is known as the “bad” cholesterol). Another small study showed that lycopene was reducing total cholesterol levels and as a result was lowering the risk of coronary heart disease (CHD).
The list of benefits does not end here: the dietary oxidant reduces oxidative stress and levels of bone turnover markers, meaning that it may contribute to the bone health, especially reducing the risk of osteoporosis in postmenopausal women.

Lycopene Benefits Backed By Science

Lycopene Benefits Backed By Science

For people with mild hypertension (high blood pressure), consumption of lycopene resulted in significant reductions of systolic and diastolic blood pressures.
Infertility in males was significantly helped by lycopene intake. In a study infertile man received 8 mg lycopene per day in capsule form. Laboratory tests confirmed an increased sperm density along with functional sperm concentration and mobility. This treatment protocol with lycopene supplementation resulted in a success rate of 36% pregnancies in their partners.
Pregnant women with pre-eclampsia who were treated with lycopene supplement significantly improved, which was shown by decreased diastolic blood pressure, the reduction of pre-eclampsia and a decrease of intrauterine growth retardation, resulting in a healthier mother and baby.
Future research is pending surrounding lycopene in metabolic and inflammatory diseases and in its role of possibly preventing neurodegenerative diseases such as Alzheimer’s disease. Other inflammatory conditions such as arthritis and emphysema will likely also be shown to benefit from lycopene. Preliminary data has already indicated this.
The Food and Drug Administration (FDA) of USA has recently approved lycopene as a safe “natural coloring agent” and a Generally Recognized as a Safe (GRAS) component. The Department of Nutritional Sciences , Faculty of Medicine, University of Toronto, c/o Dr. A.V. Rao et al. who completed this meta analysis of the recent literature have recommended that we all consume a regular daily lycopene dose in our food and supplements as part of our diet for good health.

Good Nutrition Is Gender Specific

It is well known that various health concerns are related to the gender of a person, but there are findings that suggest that even nutrition has to be tailored to the needs of males or females.
Calcium is known to be beneficial to bone health, and while high calcium diet may protect a woman from osteoporosis, it does not have the same evidence for men. As a matter of fact, high calcium intake in males may increase their risk of prostate cancer. For the male it means that calcium should be used in moderation and vitamin D intake could help to offset some risks.
Fat choices, mostly sources of monounsaturated fats in the form of olive oil are important for both, men and women, and for both the omega-3 fatty acids that are found in fish are excellent. Men, especially those with a risk of prostate cancer, should be cautious about loading up on flaxseed and canola oil. Alpha-linolenic acid in these two oils may be a problem for the prostate.
Iron is also emphasized in healthy nutrition, but men need less than women. In the presence of an abnormal gene, excessive iron can accumulate to harmful deposits in various organs.
Social habits, for example the drinking of alcohol seem to have more grave implication to women than to men. The glass of wine that may help reduce the risk of heart attacks and certain strokes may seem harmless enough, and average men don’t seem to develop health problems, as long as the alcohol intake is low. Larger amounts will increase the risk of many ills for males and females alike, but even low doses of alcohol may increase a woman’s risk of breast cancer.
“Super Foods” have made headlines, and all of them are known because of their high content in antioxidants. A recent study from the University of Oslo, Norway, under Dr. Bente Halverson examined, which of them are ranking highest. At the top are, in the order of strength: blackberries, grape juice from Concord grapes, artichoke hearts, walnuts and strawberries. The researchers came up with a list of high oxidant foods on the basis of typical serving sizes.

Good Nutrition Is Gender Specific

Everybody needs to find healthy food

These are the winners among the super foods and spices: blackberries, walnuts, strawberries, artichokes, cranberries, brewed coffee, raspberries, pecans, blueberries, ground cloves, grape juice and unsweetened baking chocolate. Males as well as females of all age groups will benefit from those.
Dr H. Simon, associate professor of medicine at Harvard Medical School points out that there are fundamental facts in nutrition that apply to everyone. But there is also a fine print, which varies according to gender, age and medical conditions.

Macular Degeneration Risk Less With Vitamins

Age related macular degeneration (AMD) is one of the more frequent reasons for loss of vision in the ageing population. The disease is also the most prevalent reason for blindness in developed countries.
A group of researchers from the Netherlands made it their mandate to investigate, in which proportion antioxidants were useful in the prevention of AMD. Supplementation with vitamins C, D and E was used and also beta-carotene and zinc. The observations were made using questionnaires from the Rotterdam Study (1990-1993).

The group on which the research concentrated consisted of inhabitants 55 years of age or older living in a middle class suburb of Rotterdam. Of 5836 at the baseline with a risk of AMD 4765 had reliable data of their dietary habits. At the end of the study 4170 participated in the follow up.
Dietary intake of vitamin E and zinc was inversely associated with the development of AMD: the group with an intake of vitamin E and zinc had less macular degeneration than those whose diet was deficient. A higher than median intake of all the four nutrients, vitamin E, zinc, vitamin C and beta-carotene showed even more benefit. The risk to develop macular degeneration was reduced by an impressive 31 %.

Macular Degeneration Risk Less With Vitamins

These results are of importance to the ageing population and the elderly. A high dietary intake of the four nutrients is important in the risk reduction of age related eye diseases like AMD.
