Guest guest Posted May 21, 2007 Report Share Posted May 21, 2007 Fast Food, Trans Fats, Food Nutrition JoAnn Guest May 21, 2007 15:39 PDT The following is an excerpt from The Willner Window radio show, airing on January 9th. The show opened with a group discussion of whether the average diet was lacking in nutrients, with reference to studies of fast food nutrition, changes in the content of vitamins in fruits and vegetables, loss of nutrients in processed oatmeal, the value of supplements and new studies on the herb, Butterbur, for treating migraines. Arnie: Good afternoon everyone, this is .... Welcome to The Willner Window. For those of you who might be first-time listeners, the focus of this show is nutritional supplements–vitamins, herbs, homeopathic remedies–and their proper usage. With me this afternoon is . . Arnie: For the past couple of weeks, we have been addressing the question raised by one of our callers, " why do we need to take nutritional supplements? Why can't we just get what we need from food? " I think we've done a pretty good job of answering that question, but it is hard to ignore the constant stream of studies and research that supports the need for supplements. So we want to run down a few of them before we get to your telephone calls. Sam: First, we could talk about studies that support the position that it is unrealistic to think we can rely on diet alone. More to the point, it is unrealistic to think that telling most Americans to eat a healthy, well-balanced diet, is going to work. First, you may have heard about the recent study published in the medical journal, Lancet. This was a large, long study, and it looked at what happens to adults who eat frequently at fast-food restaurants. Here is their conclusion: " After 15 years, those who ate at fast- food restaurants more than twice each week had gained an extra ten pounds and had a two-fold greater increase in insulin resistance, a risk factor for type 2 diabetes. Diabetes is a major risk factor for heart disease. " They added the following comment: " It's extremely difficult to eat in a healthy way at a fast-food restaurant. Despite some of their recent healthful offerings, the menus still tend to include foods high in fat, sugar and calories and low in fibre and nutrients. " Dr. Podell: At the same time, the results of the latest A.C. Nielson survey reveals " only 12% of Americans claim to eat the 5 recommended servings of fruits and vegetables each day. And approximately 1/3 of the calories that people do consume are from nutrient-poor foods such as alcohol and soda. This combination has led to a population that consumes too few nutrients, which according to the Journal of American Medical Association puts people at risk for long-term health concerns. " Arnie: OK, so it should be obvious that while it would be nice if most people derived their essential nutrients from foods, for many reasons, it just isn't going to happen. Taking nutritional supplements is one obvious way for most Americans to increase their intake of those essential vitamins and minerals that they do not seem to be getting from their diet. To imply otherwise, as the caller may have been doing several weeks ago, is myopic at best, and delusional at worst. Sam: To make matters even worse, even if you tried to eat a healthier diet, you might not be able to. According to a study published in the Journal of the American College of Nutrition, December 2004, " compared to 50 years ago, today's fruits and vegetables carry smaller amounts of some key nutrients, including protein, calcium and vitamin C. " Although there is probably more than one explanation, the trend may be largely due to farmers choosing to breed higher-yielding crops. Plants have a fixed amount of energy they can spend and varieties with high yields may have less energy to take minerals from the soil and transport them around the plant or to synthesize vitamins and amino acids, which make up proteins. " Arnie: This recent study is not the first that shows a decline in the nutrient content of fruits and vegetables. And, bear in mind, we are talking, in these studies, about the raw, fresh fruits and vegetables–not the nutritient content after they have been processed. Processing, of course, results in further depletion. Dr. Podell: This is not something to take lightly. There was an article in this week's New York Times by Marian Burros, talking about oatmeal. Oatmeal contains soluble fiber, and the health benefits of soluble fiber are so widely accepted that the government has allowed companies to actually put a claim on their food label, to the effect of " Soluble fiber from oatmeal, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease, " or " Diets low in saturated fat and cholesterol that include three grams of soluble fiber from whole oats per day may reduce the risk of heart disease. " Well, that is all well and good, but what kind of oatmeal do most people eat? Rather than eat the old fashioned, steel-cut or rolled type, they eat the new flavored, instant oatmeal. The problem is that these instant versions only contain one-half as much, or less, soluble fiber! So again, we are faced with certain facts. Saying that we don't need supplements, and that we can get our nutrients from a healthy diet, is noble, but unrealistic. Supplements make sense. .. . . especially if you are using the supplement as more than just a source of nutrition. Oat bran, or soluble fiber, is a good example. We know that increased intake of soluble fiber–oat bran, psyllium, etc– can help lower elevated cholesterol. What is wrong with " supplementing " your diet with an oat bran, or other soluble fiber supplement? Arnie: This ties in to one of the other arguments about the value of supplements, of course, and this is when they are being used as therapeutic agents, not just food. When you take fish oil supplements, for example, you are not using them as a substitute for dinner. You are taking them because they contain concentrated levels of omega-3 fatty acids, which have therapeutic activity. The EPA and DHA fatty acids found in fish oil have been proven to help combat Crohn's disease, high blood pressure, high triglycerides, rheumatoid arthritis, and many other health problems. Does it makes sense, with this being the case, to say " why do we need supplements? Why can't we just eat a health diet? " Sam: Fish oil is a good example, because this is a good example of when the supplement is actually better than the food. Dr. Podell: Taking it one step further, when we talk about supplements, we are not just talking about basic vitamins and minerals. We are talking about herbs, enzymes, amino acids. Substances that, while they may be derived from natural sources, are not normally used as a source of food. These supplements can have very useful therapeutic action, and can oftentimes be used instead of more powerful, more potentially haxardous, drugs. Let's take migraine headaches, for example. We know that magnesium can help. Vitamin B2, or riboflavin, can help. The herb feverfew has long been used for migraines. In the case of vitamin B2, some studies, using doses in the area of 400 mg per day–much more than you need to prevent nutritional deficiency– the severity and frequency of migraines decreased from 50% to two- thirds, when compared to placebo. Is a high daily does of vitamin B2 going to work for you? We don't know. But wouldn't it be a logical thing to try. It's cheap. It's safe. And there is good reason to think it might help. Arnie: Here is another very impressive vote for the therapeutic value of supplements. According to a study published in the December 28th issue of Neurology, the herb butterbur, also known a Petasites hybridus, is effective for preventing migraines. They ran a three-group, parallel trial, with a total of 245 patients. There was a control group, and two groups on butterbur, ad different dose levels. The study ran for four months. The results indicated that butterbur root extract, 75 mg, twice daily, reduced migraine attack frequency approximately twice as much as the placebo. At this dose level, 75 mg twice daily, the investigators say that Petasites, or butterbur, is comparable to prescription preventive medications. Sam: I guess we could again draw the parallel between the supplement, an extract of butterbur root, and the actual plant. Eating the plant would be ill-advised. We carry butterbur, although it is not one of the more commonly used herbs in this country. We have " Petasites Concentrate Drops, " by Herb Pharm, and " Urovex Butterbur Extract, " in softgels, by Source Naturals. The Source Naturals product is standardized at 50 mg, and is also recommend for bladder control problems. http://www.willner.com/radio_04-04-04.aspx?id=34 JoAnn Guest mrsjo- www.geocities.com/mrsjoguest/ Quote Link to comment Share on other sites More sharing options...
