More Fiber in Diet Lowers Diabetes Risk

By | Diabetes, Health, Nutrition, Vitamins and supplements

Skipping breakfast seems to be nothing unusual for many individuals. Busy lives and hectic schedules contribute to a rush in the early morning. It has been emphasized by several articles, that breakfast is indeed important for a healthy jumpstart of the day. A German study which has been published in the May 14 edition of the Archives of Internal Medicine points out more clearly why breakfast may well be the most important meal of the day.

More than 25,000 adults were enrolled in a study, which found that the intake of fiber can be an effective nutritional tool to reduce the risk of developing type 2 diabetes. The connection between type 2 diabetes and the intake of cereal, fruit, vegetable and associated fiber intake, also the intake of soluble and insoluble fiber and magnesium were closely examined. During the seven year period of follow-up 844 cases of diabetes 2 were identified.

The study found that the consumption of 29 grams per day of soluble fiber was associated with a significantly lower risk of 21% less diabetes. Soluble fiber, including pectin is mostly found in fruit, vegetables and legumes. Roughage alone such as wheat bran, whole grains and brown rice was not associated with a lower diabetes risk.

Once the source of fiber was broken down according to origin (fruit, vegetable or cereal), the study found that the participants who consumed the highest part of cereal fiber had a 28% lower risk of diabetes compared to those who had the lowest amount of cereal fiber intake. High magnesium intake was associated with a 23% lower risk.

It has to be stressed that not every breakfast cereal qualifies as a source of high cereal fiber. Consumers must become educated and be aware of the fiber content in food servings to ensure that they are getting the necessary amount to reap the benefits.

New Cure For Drug Resistant Bacteria At The Horizon

By | Health, Infectious Disease

Drug resistant bacteria (like MRSA, methicillin resistant Staphylococcus aureus) have developed in many hospitals and have caused more than 2 million infections in the US alone of which 90,000 people died. Yet so far research regarding this problem has been very slow and unsuccessful. In Canada there was an outbreak of E.coli, which left 14 people severely ill and simultaneously there was a similar outbreak in the US leaving three people dead.

Dr. Redinbo, PhD in biochemistry and biophysics, from the University of North Carolinaat Chapel Hill made an astounding discovery in his lab. He tested some of the older medications used for osteoporosis treatment, the biphosphonates clodronate and etidronate, to see whether they would have an effect on stopping the multiplication of these harmful bacteria. Dr. Redinbo’s work was published in the July 13 edition of the Proceedings of the National Academy of Sciences. Dr. Redinbo’s team found that an enzyme, called relaxase, is at the center of the development of antibiotic resistance. When resistance develops, there is a genetic transformation that takes place, like a mini Darwinian selection process where the most resistant bacteria survive and multiply. The resistant bacteria mate with each other and with bacteria that are not yet resistant. This process involves the relaxase enzyme system, some DNA stranding and a strand exchange. In this way new resistant bacteria are formed. Experiments under the supervision of Dr. Redinbo found that this process can be stopped by the phosphate-rich compound, biphosphonates (clodronate and etidronate). Other chemicals were found to not be as effective.

The relaxase system is found in a number of problem bacterial strains, Staphylococcus strains, drug resistant Acinetobacter strains and others. Unfortunately the biphosphonates have some side-effects like stomach soreness and birth defects. The researcher said that he hopes that these drugs and perhaps others with less side-effect will offer new treatments for antibiotic resistant bacteria.

Waist line reduction scores in health prevention

By | Health, Hormones, Men's Health, Nutrition, Obesity, Prevention

To women waist measurement has always been of importance. Increased waist measurement and weight gain go hand in hand, and a poor fitting garment in the waist usually signals to cut out the junk food. In the past century extremely tiny waists became an unhealthy obsession, till common sense got the upper hand.

In the past males seemed to be unperturbed by a large girth and often ridiculed the opposite sex about their preoccupation with their waist lines. With more knowledge about the intricate play of metabolism increased waist circumference is a signal to health problems. It may be that a simple measuring tape can be one of the most helpful tools to predict a group of health problems in males. While type 2 diabetes, hypertension and high cholesterol and triglycerides are the problems that would first come to mind, there are more, namely coronary artery disease, prostate enlargement, a high prostate-specific antigen level, erectile dysfunction and ejaculatory dysfunction. Dr. Steven Kaplan, professor of urology at Cornell University, New York presented a study at the American Urological Association. Men with moderate to severe urinary tract symptoms were divided into groups based on their waist sizes, 30 to 36 inches, 36 to 40 inches and greater than 40 inches.

Results surprised even the researchers. Metabolic disorders like diabetes showed an incidence of 11.25% in the first group, 22.3 % in the next higher group and 37.8% in the group with waistlines over 40 inches. Erectile dysfunction was seen in 34.6%, 49.5% and 78.6 % respectively. The percentiles for hypertension showed 12.6% in the first group, versus 24.7% and 37.8 %. The researchers stressed that male pelvic dysfunction and the derailment of metabolic function, also known as the “metabolic syndrome” are closely linked.

Olive Oil No Magic Elixir

By | Health, Nutrition

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 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.

Avoiding Back Pain By Relaxed Sitting

By | Arthritis, Health, Pain, Prevention

This article is about “avoiding back pain by relaxed sitting”. Notably, parents and educators often reprimand children and students to “sit up straight”. The results however are not that favorable. Truly, a 90 degree angle in this position is causing problems. Specifically, it causes the largest movement of the spinal disc and a lot of strain. To put it another way, conventional wisdom has it that sitting up straight avoids back pain. It must be remembered, this has important implications for a large population group that has work situations with mostly sitting jobs. In addition, consequences of bad posture are also quite visible: lower back pain is the leading cause of disability in the U.S. and Canada and a major cause for missed work days.

Improper posture and back pain are related

Investigators have presented evidence, that a 135 degree body/thigh sitting position, leaning back, is the optimal position to avoid back pain. The author of the study, Dr.W. Bashir from the department of radiology and diagnostic imaging at the University of Alberta Hospital in Edmonton emphasizes, that the angle of posture has been under question for some time, and improper posture and back pain are related.

Positional MRI scans 

Positional MRI scans have shed more evidence on the spine. There are special MRI machines that take images when the patient is not in a supine position, but in a position that allows the patient free motion during the test. Spinal angles can be measured and spinal disk movement can be observed in various positions and angles.
The 90 degree angle showed most spinal disk movement, creating stress for the spine. Another unfavorable position is a slouching posture.

Avoiding Back Pain By Relaxed Sitting

Scan results showed a reduction in spinal disk height, signifying more wear and tear of the lumbar spine. Spinal disk movement was least pronounced with the 135 degree angle. This more relaxed position poses less strain on spinal disks and the associated muscles and tendons. Employees sitting comfortably versus sitting up straight can make the job place friendlier to people’s backs.

Lycopene Benefits Backed By Science

By | Cancer, Diabetes, Health, Heart Disease, Nutrition, Osteoporosis

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.

Ballroom Dancing Improves Heart Health

By | Fitness, Health, Heart Disease, Prevention

It has been pointed out that there is not such a notion “It’s too late now to think of an exercise program”.
Researchers led by Dr. Romualdo Belardinelli, director of cardiac rehabilitation from the Lancisi heart Institute in Ancona, Italy took a close look at 110 patients with stable chronic heart failure. The average age of the patients was 59 years and 89 of them were men. The group was assigned different physical activities. Forty-four patients used an exercise bike or exercise treadmill three times a week for 8 weeks. Forty- four other patients chose to participate in 21-minutes of ballroom dancing consisting of waltzes (alternating slow and fast) three times per week. A third group of 22 patients had no exercise. Heart rates during exercise training and dancing were similar at 110 respectively 113 beats per minute. Cardiopulmonary fitness improved at a similar rate in both groups. Oxygen consumption increased by 16 % in the exercise group and by 18% in the dance group. In other words, exercise fitness had significantly improved in these two groups.

Quality of life as measured by the Minnesota Living With Heart Failure Questionnaire improved significantly more in the ballroom dance group, particularly in the emotional domain.

The findings are not just of significance to patients with heart failure. It is the observation that ballroom dancing seems to be a more effective way to get people into an exercise program who otherwise would not be interested in this. For some people it is simply more enjoyable to dance and enjoy social interaction as an additional benefit than running on a treadmill.

Cinnamon And Multivitamins May Boost Fertility

By | Health, Nutrition, obstetrics, Vitamins and supplements, Women’s Diseases

Prenatal vitamin supplements are the norm, as folic acid has been known to play a role in the prevention of neural tube defect. Generally they are taken once pregnancy has been confirmed.
Dr Jorge Chavarro from the department of nutrition at the Harvard School of Public Health in Boston pointed out, that multivitamin supplementation has its place earlier than just after the pregnancy test has become positive. In one of the largest studies involving 18,000 married pre-menopausal women, regular use of multivitamin supplements were associated with a decrease of infertility. The key is in the regular use. Women who took two multivitamin tablets per week had similar infertility rates as women who did not take supplements at all. Those who took 6 or more multivitamins had a 40% lower risk of anovultation, a condition where no eggs are released by the ovaries.
Most of the women were Caucasian between the ages 24 and 42.
The importance of nutrition is coming increasingly into the forefront in reproductive medicine. One condition known as polycystic ovary syndrome (PCOS) is often a reason for infertility. It is one of the red flags that point to the condition of insulin resistance, and it manifests itself in menstrual irregularity and higher levels of androgens, often showing as increased facial hair. As the metabolism is headed for trouble, diabetes, high blood pressure, high cholesterol and heart disease would tend to develop.
Researchers at Columbia University in New York conducted a pilot study to see if insulin sensitivity in women with PCOS could be improved. Cinnamon, a well-known spice, has been known to have a favorable effect on the insulin response of the body. Researchers found that eight weeks of treatment with cinnamon extract significantly decreased fasting glucose and insulin resistance in women with polycystic ovary syndrome.

Cinnamon And Multivitamins May Boost Fertility

Dr. Jeff Wang who conducted the study reported that no side effects or adverse reactions were reported throughout the study period. If large-scale prospective studies confirm these findings, then recommending cinnamon as a dietary factor may be a simple, inexpensive lifestyle change that can be easily followed. Reducing insulin resistance is a key to improve the overall health status in patients with PCOS, and it ties in with reproductive health benefits as well.

Good Nutrition Is Gender Specific

By | Cancer, Health, Heart Disease, Nutrition, Prevention, Stroke

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.

Food Choices Can Boost Good Cholesterol

By | Health, Nutrition, Obesity, Prevention

Dr. Andrew Pipe, a cardiologist at the University of Ottawa Heart Institute, sees a lot of people with cardiovascular problems. He also has found that telling patients to “reduce their cholesterol and get the triglycerides down” is not very helpful. Dr. Pipe is aware that we are living in a world where people are constantly tempted by junk food, and it is not surprising that obesity is one of the consequences.
It sounds daunting to a person with a lifetime of poor food habits and poor lifestyle choices to make changes. He believes that simplifying advice for healthy living can be brought down to 5 F’s for healthy living:

-Fruit and vegetables, 3-4 each day
-Fish, 3-4 per week
-Fibre, 5 per day
-Fat, 3-6 per day. Monounsaturated fats are best
-Fast food: avoid it!

Food Choices Can Boost Good Cholesterol

Food Choices Can Boost Good Cholesterol

To this list Dr. Pipe added two more Fs:
– “Fysical” activity, 30-40 minutes per day. This may be a misspell, but it is the best way to increase your good cholesterol (HDL)
-Fun, unlimited. Your food choices and exercise need to be enjoyable and appealing or the plan does not work in the long run.
