Abstract


Background: It has been claimed for many decades that meat is a risk factor for colorectal cancer, and that it has no compensating benefits in terms of cancer risk. The evidence for this has been critically reassessed.

Methods: The epidemiological evidence, particularly that produced in recent years, has been re-examined to determine whether it is sufficiently consistent to warrant giving firm advice to the general public.

Results: Far from being supportive, the epidemiological data does not justify this claim. A large mass of evidence is presented from case-control studies and prospective studies, in which the data from Europe are not consistent with those from the United States. This is because of the different contexts (in terms of meal composition) within which meat is consumed in different countries. In fact the epidemiological data are much more consistent with there being a protective role for fruit, vegetables and whole grain cereals and no role for meat in colorectal cancer, and a protective role in gastric cancer.

Conclusions: Meat is a good source of protein, readily available iron, calcium, magnesium, selenium, zinc and a range of B vitamins. Since the evidence for any role in colon carcinogenesis is so weak, and since such a high proportion of women of child-bearing age are iron deficient, the consumption of meat, as part of a balanced and varied diet, should be actively encouraged.

I have the hla-dbq1*0301 and 0602 genes, one of which predisposes to gastric cancer. Magnesium and zinc deficencies are asssociated with ADD

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
