Age, stress, and poor nutrition can sap our immune system of its effectiveness. Influenza provides one example. During young adulthood, when the body can mount a robust immune response to this common virus, influenza is rarely fatal. Among the elderly, however, the virus is associated with significant rates of death and hospitalization (Nichol KL 2005). The impact of aging on the immune system is profound. As people age, a number of critical immune system components are reduced or slowed, including cellular response, response to vaccines, and antibody production. At the same time, susceptibilities to infection and cancer are increased. Some of this increased susceptibility to disease is linked to chronic inflammation, which is associated with many disorders of aging (Ershler WB et al 2000; Hamerman D 1999; Taaffe DR et al 2000).

Coconut oil is one of the few saturated fats that doesn't come from animals, but like other saturated fats can raise cholesterol levels and, therefore, should play only a very limited role, if any, in your diet. In the past, it was widely used in movie popcorn, candy bars and commercial baked goods but was phased out of many of them because of consumer opposition to unhealthy tropical oils. Now coconut oil is being promoted as a weight loss aid; it is also touted in a book by a naturopathic doctor. The rationale goes something like this: as a source of medium-chain triglycerides (MCT), coconut oil isn't stored in the body as fat as readily as oils composed of long-chain triglycerides (LCT). Some research from McGill University in Canada suggests that this is true; MCTs also boost metabolism and satiety, and therefore may promote weight loss when they replace LCTs in the diet. Because they are so easily digested, MCTs are given in hospitals to provide nourishment for critically ill people who have trouble digesting fat. The benefits of coconut oil in the diet, if any, are likely to be minimal, and until we have more and better evidence about coconut oil's effect of metabolism and potential role in promoting weight loss, I do not recommend using it.

"One of the very useful oils in the food supply comes from the coconut. Coconut oil has suffered from unjust criticism for more than 30 years in the United States because some of the governmental and food oil organizations, as well as consumer activist organizations such as Center for Science in the Public Interest (CSPI), have claimed that coconut oil as a "saturated fat" is shown to be atherogenic. This is not true. There is a variety of supportive research published in 2003, 2004, and 2005, which shows the importance of coconut oil. Also, information on coconut oil is currently coming into the research literature from numerous countries, including India, Norway, Iran and the United States. The following are some of the most recent studies showing the benefits of coconut oil. These studies contradict claims that coconut oil contributes to heart disease and also support earlier research showing an antimicrobial role for the fatty acids in this traditional fat."

How could changes in diet explain changes in coronary heart disease mortality in Spain? The Spanish paradox. Serra-Majem L, Ribas L, Tresserras R, Ngo J, Salleras L. Am J Clin Nutr. 1995 Jun;61(6 Suppl):1351S-1359S. PMID: 7754987 We review and compare trends in coronary heart disease (CHD) and stroke mortality in Spain from 1966 to 1990 and changes in food consumption at national and regional levels. Since 1976, a decrease in cardiovascular disease (CVD) mortality in males and females has been observed, and standardized CHD mortality rates have fallen. Stroke mortality decreased during the same period. Trends in food consumption show increases in intakes of meat, dairy products, fish, and fruit, but decreases in consumption of olive oil, sugar, and all foods rich in carbohydrates. Although fat and saturated fat intakes increased, these changes were not accompanied by an increase in CHD mortality rates. This paradoxical situation can be explained by expanded access to clinical care, increased consumption of fruit and fish, improved control of hypertension, and a reduction in cigarette smoking. Diet appears to have an important role in this paradox, but it may not be as critical as other factors. Nevertheless, we suggest dietary guidelines for prevention of CHD in Spain.

n-3 fatty acids and gene expression. Deckelbaum RJ, Worgall TS, Seo T. Am J Clin Nutr. 2006 Jun;83(6 Suppl):1520S-1525S. Review. Erratum in: Am J Clin Nutr. 2006 Oct;84(4):949. PMID: 16841862 Accumulating evidence in both humans and animal models clearly indicates that a group of very-long-chain polyunsaturated fatty acids, the n-3 fatty acids (or omega-3), have distinct and important bioactive properties compared with other groups of fatty acids. n-3 Fatty acids are known to reduce many risk factors associated with several diseases, such as cardiovascular diseases, diabetes, and cancer. The mechanisms whereby n-3 fatty acids affect gene expression are complex and involve multiple processes. As examples, n-3 fatty acids regulate 2 groups of transcription factors, such as sterol-regulatory-element binding proteins and peroxisome proliferator-activated receptors, that are critical for modulating the expression of genes controlling both systemic and tissue-specific lipid homeostasis. Modulation of specific genes by n-3 fatty acids and cross-talk between these genes are responsible for many effects of n-3 fatty acids.

"(NaturalNews) People still don't get it: Vitamin D is the "miracle nutrient" that activates your immune system to defend you against invading microorganisms -- including seasonal flu and swine flu. Two months ago, an important study was published by researchers at Oregon State University. This study reveals something startling: Vitamin D is so crucial to the functioning of your immune system that the ability of vitamin D to boost immune function and destroy invading microorganisms has been conserved in the genome for over 60 million years of evolution. As this press release from Oregon State University (http://www.eurekalert.org/pub_relea...) explains: The fact that this vitamin-D mediated immune response has been retained through millions of years of evolutionary selection, and is still found in species ranging from squirrel monkeys to baboons and humans, suggests that it must be critical to their survival, researchers say. "The existence and importance of this part of our immune response makes it clear that humans and other primates need to maintain sufficient levels of vitamin D," said Adrian Gombart, an associate professor of biochemistry and a principal investigator with the Linus Pauling Institute at Oregon State University."

"While research in lectinology is in its infancy this information is critical to your health and it is important to begin to understand lectins NOW. Read the following report carefully. I'll get specific about how this all applies to you. ALL foods contain lectins. Some are your friends, others neutral, and others may be your enemies. Know your lectins. Avoid your enemies. DEFINITION Protein or glycoprotein substances, usually of plant origin, of non-immunoglobulin nature, capable of specific recognition of and reversible binding to, carbohydrate moieties of complex glycoconjugates without altering the covalent structure of any of the recognized glycosyl ligands. This group includes monovalent lectins (i.e. bacterial and plant toxins). These lectins bind to sugar moieties in cell walls or membranes and thereby change the physiology of the membrane to cause agglutination, mitosis, or other biochemical changes in the cell. (agglutination- clumping; mitosis-multiplication or division of a cell forming two daughter cells) High levels of lectins (specialized proteins) may be found in grains (also known as cereals or pulses), legumes (that is 'beans' including peanuts), dairy and plants in the nightshade family. Many other foods contain lectins but are less well studied and the amounts of lectins present are not thought to be as high or as potentially toxic.!

Welcome to the English language website for the "Optimal Diet" movement. The Optimal Diet is a dietary model of human nutrition devised and implemented by Dr. Jan Kwasniewski. The Optimal Diet is a movement, which originated in recent years in Poland, and has rapidly spread to a number of countries worldwide, is to improve the well-being, health and biological value of people as individuals, and to correct nutritional mistakes of human kind as a whole, through promotion and implementation of the "optimal" model of human nutrition. Optimal Diet is based on the delivery of the most important nutritional elements, e.g., the most valuable proteins and fats, whilst leaving the body in charge of the distribution of these elements to the most critical areas. The ideal proportion between the main food components of protein, fat and carbohydrates should be in the range of : m m m m 1 : 2.5 - 3.5 : 0.5 In order to work out the correct daily food intake using this proportion, one has to know how many grams of protein needs to be ingested in a day to satisfy body's requirements.

Induction of ovarian cancer cell apoptosis by 1,25-dihydroxyvitamin D3 through the down-regulation of telomerase. Jiang F, Bao J, Li P, Nicosia SV, Bai W. J Biol Chem. 2004 Dec 17;279(51):53213-21. Epub 2004 Oct 12. PMID: 15485861 doi: 10.1074/jbc.M410395200 Overall, the study suggests that the down-regulation of telomerase activity by 1,25(OH)2VD3 and the resulting cell death are important components of the response of OCa cells to 1,25(OH)2VD3-induced growth suppression. Progressive shortening of telomere associated with cell divisions limits the life span of normal cells and eventually leads to senescence. To become immortal, human cancers including OCa are invariably associated with activation of mechanism that maintains telomere length. Approximately 85-90% of cancers show reactivation of telomerase. The present study shows that telomerase in OCa cells is down-regulated by 1,25(OH)2VD3. Down-regulation of telomerase is due to decreased stability of hTERT mRNA rather than VDRE-mediated transcriptional repression through the putative VDRE present in the regulatory region of the hTERT gene. It is known that the inhibition of telomerase may lead to a phenotypic lag during which cells would continue to divide until the point at which the telomeres became critically short. This phenomenon may explain why the apoptotic induction by 1,25(OH)2VD3 needs the treatment for more than 6 days. As mentioned in the results, no detectable shortening of telomeric repeats was observed in parental OVCAR3 cells after 9 days of treatment with 1,25(OH)2VD3 (Fig. 4D). This is likely due to the fact that the short telomere (about 3 kb) in OVCAR3 cells is very close to the minimal length required for survival and that cells with detectably shorter telomere may have been selected against apoptosis. It has been shown that transformed human cells enter crisis once the terminal restriction fragment of the telomere reaches a length of about 4 kb. This is insufficient to protect chro

For many years, vitamin D was boring--even to doctors. Because it was considered good for bones and not much else, multitaskers like vitamin A, B vitamins and vitamin E hogged all the press. But recent studies have thrust this long-neglected nutrient into the spotlight. Scientists now think vitamin D may affect everything from diabetes to cancer. They're also finding that many people don't have enough of it.

Excerpt: Coming soon to a grocery store near you: a speed-read nutrition label on the front of food packages that provides large-type icons that list the amount of calories, fat, sodium and sugars. New labels, called Nutrition Keys by the food industry that created them, were announced Monday by the Food Marketing Institute and the Grocery Marketing Assn. The groups say they developed the labels in response to First Lady Michelle Obama's anti-obesity campaign that in part calls for an easier way for shoppers, especially parents, to make informed food choices. Aside from the four main icons, the industry groups may include "nutrients to encourage" -- such as icons for the amount of potassium, fiber, protein, vitamin A, vitamin C, vitamin D, calcium and iron. (Note, small packages will have a calorie count icon only.) The new labels don't replace the nutritional label Americans have come to rely on for product information; rather, they add to it. The labeling will be phased in on packages by the end of the year. Not everyone thinks this is a great idea. One critic, author Marion Nestle, writes on her Food Politics blog: "Forget the consumer-friendly rhetoric. There is only one explanation for this move: heading off the FDA's Front-of-Package (FOP) labeling initiatives." Here's what the FDA currently requires companies to supply on food labels.

Critics say a government plan to cut back on potatoes and sodium in the federal school lunch program will result in meals children will not eat.
