“According to a report by a World Health Organisation agency red meats are linked to cause cancer in humans. The determination, published by a panel of researchers for the International Agency for Research on Cancer in a medical journal Monday, classifies processed meat products like salami and bacon carcinogenic to humans, the strongest level of risk for cancer, and a category shared with tobacco smoke and diesel engine exhaust.
A metaanalyse of more than 800 studies by the commettee followed many people over time. Surprisingly one of the result turned out that even small amounts of daily consumption of meat are associated with an increased risk of certain types of cancer. Some of the studies showed that there was 17% increase in the risk of colorectal cancer for every 100 grams per a day of red meat consumed and an 18% increase for ever 50 grams daily of processed meat…”
“Many people, including vegetarians, consume substantial amount of diary products depite scientific evidence that questions about their health benefits and indicates their potential health risks. Milk and dairy products are not necessary in the diet and can, in fact, be harmful to health. It is best to consume a healthful diet of grains, fruits, vegetables, legumes, and fortified foods including cereals and juices. These nutrient-dense foods can help you meet your calcium, potassium, riboflavin, and vitamin D requirements with ease—and without facing the health risks associated with dairy product consumption.”
Here are some reasons why we should avoid milk and dairy products.
little benefit for bones
fat content can cause cardiovascular problems
riskfactor of various cancers
milk proteins and diabetes
health concerns for children, infants and their developement
Scientists call for further study after failing to decide whether brain differences are cause or effect of porn consumption.

Less grey matter is found in the brains of men who watch large amounts of sexually explicit material, a study has found. The research, published in the journal JAMA Psychiatry, could not determine if porn actually caused the brain to shrink, however, and the authors called for more study on the topic.
“Future studies should investigate the effects of pornography longitudinally or expose naive participants to pornography and investigate the causal effects over time,” said researchers at the Max Planck Institute for Human Development in Berlin.
The institute recruited 64 male subjects aged 21-45 “with a broad range of pornography consumption”.
The men were not told initially that the research was monitoring their brains on porn, rather that it was “a scientific study including magnetic resonance imaging (MRI) measurements”.
The men were told during a later phone interview that questions about pornography would be part of the research, and none dropped out.
The men filled out surveys, describing how much porn they watched. Their responses averaged a little more than four hours a week.
Their brains were scanned with MRI technology while they were shown sexually explicit images from porn websites, along with non-sexual images of people exercising.
“Our findings indicated that grey matter volume of the right caudate of the striatum is smaller with higher pornography use,” the researchers said.
Furthermore, when sexually explicit material was shown, the men’s MRIs showed diminished function in a part of the brain that processes motivation.
But were men with smaller striatums seeking more porn, or did more porn make the brain smaller? Was it a consequence, or a precondition?
“Individuals with lower striatum volume may need more external stimulation to experience pleasure and might therefore experience pornography consumption as more rewarding, which may in turn lead to [more porn watching],” said the authors, concluding that more study is needed.
Certain cancers—like breast cancer—can be thought of in part as an autoimmune disease.
When people get heart or kidney transplants, they must be given immunosuppressive drugs to prevent rejection of the new organ. What do you suppose happens to cancer rates in those individuals who have their immune systems suppressed? Well, for some types of cancer, like skin cancer, the risk goes up. This supports the so-called immune surveillance theory—the idea that our immune system acts as a natural defense system for keeping cancer under control (see a cool video of immune cells taking on a cancer cell here). This could explain why, as we age and our immune function declines, our risk of cancer goes up. Continue reading →
