Macular Degeneration Risk Less With Vitamins

By | Eye Diseases, Nutrition, Vitamins and supplements

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 %.

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.

Food Habits Related To Asthma

By | Asthma, Nutrition, Prevention

High quality dietary data have made it possible for a research team in North Carolina to address how a diet rich in meat, salt, starches (=refined carbohydrate) and fat can have an impact on respiratory problems and asthma.
Stephanie London and her team examined the data of 52,535 people between the ages of 45 and 74 years of age. A baseline examination was started in 1993, and follow-ups were done in 1999. All of the participants lived in Singapore. After adjustments were made for age, gender, smoking and education. It was observed that dietary habits could make a difference to respiratory health. Two eating patterns emerged: one group gravitated towards dim sum, meat and noodle dishes, whereas the other group favored fruit, vegetables and soy products. The “meat and dim sum” group had a 1.43 times higher risk of developing breathing problem, new-onset cough and phlegm formation. There was also a link to chronic respiratory disease and asthma.

The researchers concluded also, that the habits observed in the Singapore study are very much in keeping with dietary habits in western countries, where one group consumes foods high in starch, fat, meat and sodium and a second group has a more health conscious approach preferring, vegetables, fruit, legumes, fish, poultry and whole grains.
As a result the same recommendations are applicable to in western countries: stick to food choices with a low glycemic index and skip the noodle dishes. Stay away from trans fats and limit the saturated fats, which means turning away from deep-fried foods and limiting meat intake. Choose fish, vegetables and legumes, and avoid the high sodium content, which is common in many premixed and prepared foods. If you are doing the cooking, go easy on salt, and ban the saltshaker from the dining table.

A lot has been said about good food habits and a reduction in cancers and heart disease. What is new is the fact that food habits also have an impact on the health of our respiratory system.

Hospital Cafeterias Need Healthier Food

By | Health, Nutrition, Prevention

Cafeterias and fast food restaurants have come under scrutiny for offering food choices that are not compatible with healthy living. In a place where healthcare is the prime concern, like in the cafeteria of a hospital, one should hope that promoting good health should be the norm.
A U.S. wide survey tells another story: hospitals are falling short of providing meals that are healthy and heart-friendly. There are some trends, such as the availability of fresh fruit and wholegrain products, but the overall picture points to an urgent need for improvement. The survey was conducted by the Physicians Committee for Responsible Medicine (PCRM, for short). This advocacy group for ethical and preventive medicine distributed questionnaires, inquired about sample menus as well as recipes for one of the “healthiest menu items available from the hospital’s main eating establishment”. It turned out that sixty-two percent of the “healthiest entrée” choices derived more than 30% of calories from fat, and a few derived more than 50% of calories from fat.

Although at least 80% of responding hospitals offered wholegrain products, sugar-free snacks and fresh fruit, less than a third offered a daily salad bar. Artery-clogging fats in hospital food also prevailed. Fried chicken was the top selling item in 24% of the hospital cafeterias and hamburgers in 12% of the surveyed cafeterias. Other top sellers included pizza, enchiladas and meatloaf. Less than one third offered non-dairy options or soymilk.
The recommendations to promote more health conscious food were very much common-sense: food services should offer daily salad bars, use fresh rather than canned vegetables, incorporate organic ingredients and hearty vegetarian soups daily. Fatty or cholesterol-laden add-ons such as bacon, mayonnaise, croutons and sour cream should be optional. Beans should also be offered as well as healthy items from other countries’ cuisines.

In the meantime it is up to the consumer to be prudent in making the better choices. This may involve turning a cold shoulder to cafeteria food and seek healthier choices elsewhere. For the visitor it may mean that bringing a brown bag or a take-away with a salad would be more appropriate than bringing a bunch of flowers for a loved one in the hospital.

Lycopene For Bone Health

By | Nutrition, Osteoporosis, Prevention, Women’s Diseases

The tomato pigment Lycopene in the diet has been demonstrated to be a beneficial agent in reducing age-related diseases, cardio-vascular disease and even prostate cancer. A new aspect has now been investigated.
Consuming more lycopene in the diet is of significant benefit to post-menopausal women, as it reduces oxidative stress and bone turnover. The findings come from head researcher Erin Collins from the University of Toronto. The study results also suggest, that dietary lycopene is readily absorbed, particularly in combination with vitamin C. These results are encouraging, as lycopene may be one of the main agents important for the prevention of osteoporosis.” We found that women who consumed more tomato products on a daily basis had a lower bone turnover and lower oxidative stress than women of the same age group who did not consume as much”, reports Ms. Collins. The participants of the research project were between 50 and 60 years. Lycopene levels in the blood were analyzed, and a seven-day food record was completed. The lowest quartile of estimated lycopene intake was 1.8 mg per day, and the highest was 8 mg per day. Lab tests also showed that higher levels of lycopene were associated with a lower level of protein oxidation and cross-linked N-telopeptides of type I collagen, for short NTx. The latter one is a marker of bone turnover. The intake of vitamin C appeared to work together with lycopene, but it only showed to have a correlation, if 500 mg per day or more of vitamin C was consumed. The effect was not observed among the volunteers who consumed less than 500 mg per day of vitamin C.
An intervention study will begin shortly, which will be the first of its kind. It will assess the bone parameters in women treated with different doses of lycopene pills.

It is likely that follow-up studies will confirm initial findings, and dietary lycopene could become a simple, inexpensive way of helping to prevent osteoporosis.

Hard Liquor And Beer Hike Colon Cancer Risk

By | Cancer, Nutrition, Prevention, Substance abuse

The old adage of “everything in moderation” has become something like an excuse-me note for those who do not wish to change their lifestyle. And the little bit that supposedly does not harm is another variation in the theme of excuses. Yet the truth remains, that this does not apply to various lifestyle habits. It still matters, what you ingest in your food or drink, as Dr. Joseph Anderson found out in a study of 2,291 patients.

All of these individuals presented for screening colonoscopy. It turned out that those who had a history of consuming more than 8 drinks of spirits or beer per week for at least ten years were more than twice as likely as abstainers to have significant cancer of the colon. The group that drank beer and hard liquor (and hard liquor also applies to the category of mixed drinks) faced at least a one in five chance to have significant colorectal neoplasia (meaning cancer of the colon or rectum). This came as no surprise to the researchers, as beer and hard liquor seem equally pernicious.
Even though wine does not seem to carry the same risk, Dr. Anderson is in no position to condone counseling patients to drink wine instead.

His advice to other doctors is to ” counsel the patients on what they are drinking and counsel them to temper their drinking.”

Pre-Conception Nutrition For Healthy Children

By | Health, Nutrition, obstetrics, Prevention, Vitamins and supplements

The importance for good maternal nutrition during pregnancy has been emphasized for a long time. Of course in this case it was up to the mom-to-be to avoid toxins, such as smoking and alcohol and to take prenatal supplements along with sensible nutrition. Enticing the women away from the excesses of the standard Western diet would yield handsome health benefits for the country. Dr. David Barker, a medical advisor to the British government pointed out, that this approach would reduce heart disease, diabetes and other chronic diseases in the mothers as well as in their offspring. This concept does not address all the aspects, which are important for a healthy pregnancy and a healthy baby.
For the past 20 years a group of around 20 British family physicians, obstetricians and researchers under the name of Foresight has been putting a program into practice, which identifies and addresses the health deficiencies in prospective parents. Almost all couples that followed the pre-conception program had previously experienced problems relating to conception, pregnancy and birth. In one follow-up study of 367 couples that followed the Foresight program from 1990 to 1992, 327(89%) of the women became pregnant and had healthy, well-developed babies. None of the babies suffered malformations and none was transferred to special care. Of the 367 couples, 217(59 %) had suffered from infertility (from 1 to 10 years) and 139 (38%) had histories from 1 to 5 previous miscarriages. Eleven (3%) had previously given birth to a stillborn child, 40 had small-for-date babies and 15 had already had a low birth weight baby (less than 2,500 g). Seven couples had a previous baby with malformations and three had lost a baby to sudden infant death.
In a larger follow-up study of 1,076 couples, almost all of whom had previous fertility or miscarriage problems, 846 conceived success rate of 78%, as reported by Belinda Barnes, who runs Foresight. There were four problem pregnancies, including one Down syndrome baby, two terminations and one child with an adhesion of the intestine, which was correctable. This is a complication rate of only 0.47 %.

Pre-Conception Nutrition For Healthy Children

Pre-Conception Nutrition For Healthy Children

As the complication rate in the general population amounts to 6.43%, the pre-conception program has only 1/7th of the complications, a strong indicator that a pre-conception program does make a difference.

Exotic Mushrooms Best Source For Antioxidants

By | Health, Nutrition, Vitamins and supplements

Antioxidants provide powerful cellular protection, and several sources are available through food. One of them under the name ergothioneine was known to be available through food sources like wheat germ or chicken liver. The latter is not necessarily a popular choice for a lot of people! However, antioxidants are necessary to protect us from diseases like arthritis, Alzheimers disease and cancer.
Researchers at Penn State have better news in the meantime. Joy Dubost, who led the research team, stated in a recent press release, that exotic mushrooms like shiitake, oyster mushrooms, king oyster or maitake mushrooms contain up to 13 mg of the desirable antioxidant ergothioneine in a typical serving, about 40 times as much as wheat germ.
Consumers who are reluctant to try these varieties and are more used to Portobello mushrooms, crimini mushrooms (brown mushrooms) or even the ubiquitous white mushrooms, still get a good dose of up to 5 mg ergothioneine per serving.

Mindless Snacking Makes You Fat

By | Nutrition

Eating healthy and exercising is considered the key to healthy lifestyle and also thought to be a reliable way to natural weight loss. There seem to be other aspects that matter, according to some thought provoking research that comes out of the Food and Brand Lab at the University of Illinois.
One of the lab’s more recent experiments looked at mindless eating: people snack totally oblivious to the fact that they are not really hungry. The researchers looked at the most common venue for this habit and investigated 158 moviegoers in Philadelphia with an average age of 28.7 years. They gave them 120g pails and 240 g pails of fresh and stale popcorn. Those who received the large size pails consumed more popcorn (45.3 % more when it was fresh and 33.6 % more of the old and stale product.) When it comes to overeating, the researchers suggest, that portion size is more important than taste! The study appeared in the September/October edition of the Journal of Nutrition Education and Behavior. It also confirms the results of similar research. One member of a family who had been given a bulky 900g bag of candy to munch on during a film reported, that between four people they consumed a pound-and-a-half of M&Ms during the show. They just could not stop!
The shape of drinking glasses can also fool even veteran bar tenders. The “vertical-horizontal illusion” is an innate human sensory deficiency, and people think that a tall, skinny glass holds more than a squat tumbler, even though they both hold the same volume.

Olive Oil Combats Inflammation

By | Health, Nutrition, Prevention

The health benefits of the Mediterranean diet have received a lot of positive press, and so far the benefits have been credited to fresh fruit and vegetables, as well as olive oil. It has been pointed out that the bioflavonoids in fruit and vegetables are the positive forces at work. Also, the monounsaturated fatty acids of olive oil are part of a heart healthy diet.
Researchers from the Monell Chemical Senses Center in Galveston, Texas have found yet another piece of evidence that olive oil has positive effects on heart health. They have found a natural occurring chemical in extra-virgin olive oil which they named oleocanthal. This substance is a non-steroidal anti-inflammatory, a so-called COX inhibitor. The pharmacological action is the same as in the anti-inflammatory ibuprofen.

Dr. Gary Beauchamp (PhD) stated, “Some of the health-related effects of the Mediterranean diet may be due to the anti-COX activity of oleocanthal from premium olive oils”.

Dark Chocolate For Lower Blood Pressure

By | Heart Disease, High Blood Pressure, Nutrition

Chocolate, as long as it is consumed in moderation, can be good for you. The beneficial ingredients are the bioflavonoids, the same substances that are also found in fruit and vegetables.
Dr. Jeffrey Blumberg, PhD, at Tufts University in Boston reported about a study, where 20 adults with hypertension (high blood pressure) were asked to eat white chocolate or dark chocolate for 15 days. Blood pressure was reduced by an average of 12/9 mmHg with the dark chocolate. White chocolate had no effect, as blood pressures stayed the same. Dark chocolate also caused a dip in the LDL cholesterol and lowered insulin resistance.
The reason for the benefits lies in the bioflavonoids content: dark chocolate is rich in bioflavonoids, whereas milk chocolate contains little, and white chocolate the least of the three.
For all chocoholics this is not a ticket for a box of Belgian dark chocolates or an assortment of candy bars in one sitting.

Moderation is still the key, and you may consider consuming cocoa, perhaps as a Mexican chocolate drink without the fat and without the sugar.
