Calorie-restricted diets are thought to protect against cancer and slow tumor growth, and a new study published in this week's Nature begins to tease out why the measure works for some tumors, and not for others. For almost a century, researchers have known that fasting helps animals live longer and avoid some cancers, "but which type of cancers would be amenable to this approach, from a therapeutic standpoint, is still an open question," said Pier Paolo Pandolfi, a cancer geneticist at Harvard Medical School and Beth Israel Deaconess Cancer Center in Boston, Mass., who was not involved in the study. The study is exciting because it is one of the first to start answering that question at the genetic level, he said.

there are many superfoods that never see the inside of a shopping cart. Some you've never heard of, and others you've simply forgotten about. That's why we've rounded up the best of the bunch. Make a place for them on your table and you'll instantly upgrade your health -- without a prescription.

Heart scan scores starting dropping not just 2%, or 8% . . . but 24%, 30%, 50% and more. We also began to see a larger proportion of people achieving these larger successes. Why? I attribute the surge in success to the addition of vitamin D. With vitamin D added to the mix of strategies in Track Your Plaque, HDL cholesterols went up much higher, LDL dropped further, blood sugars dropped, blood pressures dropped. People felt better, had more energy, gained more clarity in thought. And heart scan scores dropped more readily.

It's weird. Instead of getting hoodia free trial for weight loss, some people choose to buy it. Why? Isn't a free trial the most risk free way to try a product. And now those interested to eat less can really do so because for a limited time, this selected hoodia supplement is giving away hoodia free trial. I'll go get the free trial now because what can be better than free?

"Today, goldenseal is marketed as a tonic to aid digestion, sooth upset stomach, and as an antibacterial and antiviral agent. It is considered a natural antibiotic and is most often combined with echinacea in preparations designed to strengthen the immune system. Many professional herbalists recommend goldenseal in herbal remedies for hay fever (also called allergic rhinitis), colds, and the flu. Goldenseal is considered a useful antiseptic (which is why some herbalists use it topically to disinfect cuts and scrapes) and astringent. It is commonly used to treat severak skin, eye, and mucous membrane inflammatory and infectious conditions (such as sinusitis, conjunctivitis, and urinary tract infections). It is also available in mouthwashes for sore throats and canker sores. Goldenseal has not been thoroughly investigated in scientific studies, but some trials have looked at berberine, one of the active compounds in goldenseal. Berberine is a substance widely used in Traditional Chinese Medicine to treat dysentery and infectious diarrhea. Berberine may be effective in humans for malaria, heart failure, and various types of infections, including upper respiratory problems."

"As far as I can tell, MK-4 is capable of performing all the functions of vitamin K. MK-4 can even activate blood clotting factors, which is a role traditionally ascribed to vitamin K1. Babies are often born clotting deficient, which is why we give newborns vitamin K1 injections in the U.S. to prevent hemorrhaging. In Japan, they give children MK-4 to prevent hemorrhage, an intervention that is very effective. Could that have to do with the fact that Japan has half the infant mortality rate of the U.S.? Today, I found another difference between MK-4 and MK-7. I was reading a paper about SXR-independent effects of vitamin K2 on gene expression. The investigators found that MK-4 strongly activates transcription of two specific genes in osteoblast cells. Osteoblasts are cells that create bone tissue. The genes are GDF15 and STC2 and they're involved in bone and cartilage formation. They tested K1 and MK-7, and in contrast to MK-4, they did not activate transcription of the genes in the slightest. This shows that MK-4 has effects on gene expression in bone tissue that MK-7 doesn't have. That being said, MK-7 may still have a place in a healthy diet. Just because it can't do everything MK-4 can, doesn't mean it has no role. It may be able to fill in for MK-4 in some functions, or reduce the dietary need for MK-4. But no one really knows at this point. Hunter-gatherers would have had a source of longer menaquinones, including MK-7, from livers. So it's possible that we're adapted to a modest MK-7 intake on top of MK-4. "

"November 26, 2008 New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age. A report in the November 26th issue of the journal Cell, a Cell Press publication, reveals that a protein perhaps best known for its role in the life-extending benefits of a low-calorie diet also maintains the stability of the mammalian genome-the complete set of genetic instructions "written" in DNA. The researchers found in studies of mammalian stem cells that the protein SIRT1 controls the packaging of DNA into chromatin, thereby setting the youthful pattern of gene activity by keeping select genes switched off. In response to DNA damage, those SIRT1 proteins leave their posts to go off and assist in the necessary repairs. That change in SIRT1's job description leads to shifts in gene activity that parallel those seen in the aging mouse brain, they show. They suspect similar changes would also be found in other body tissues as well."

"Measuring the number of small LDL particles is the best index of carbohydrate intake I know of, better than even blood sugar and triglycerides. In other words, increase carbohydrate intake and small LDL particles increase. Decrease carbohydrates and small LDL particles decrease. Why? Carbohydrates increase small LDL via a multistep process: First step: Increased fatty acid and apoprotein B production in the liver, which leads to increased VLDL production. (Apoprotein B is the principal protein of VLDL and LDL) Second step: Greater VLDL availability causes triglyceride-rich VLDL to interact with other particles, namely LDL and HDL, enriching them in triglycerides (via the action of cholesteryl-ester transfer protein, or CETP). Much VLDL is converted to LDL. Third step: Triglyceride-rich LDL is "remodeled" by enzymes like hepatic lipase, which create small LDL"

"We are fond of grumbling about Britain's grey skies, but there may be a good medical reason for doing so. It seems the dreary weather is bad for our hearts - worse, even, than raised cholesterol and an unhealthy diet. That's the controversial claim being made by Dr David Grimes, a gastroenterologist from Blackburn. He's been gazing at the sky for 20 years for clues about why his patients get more sick than those in the south of the country. And what he's found turns key assumptions about heart disease on their head. 'It's not diet or cholesterol levels that raise your risk of heart disease,' he claims. 'It's where you live. People in the north are more likely to be ill because they get less sunshine Basically they are suffering from 'latitude' sickness. The link is vitamin D. While we get some from our diet, the main source is the sun - sunlight converts a compound in the skin into vitamin D, so the amount you make is directly related to the amount of sunshine you get. In a new book Dr Grimes argues the higher the level of vitamin D in your blood, the lower your risk of heart disease and a range of other illnesses. If he's right, what we need is not diet and lifestyle advice, but food fortified with vitamin D. For years the vitamin was thought to be useful only for preventing rickets. So how does he treat them? 'You can do it with diet,' he says 'One Bangladeshi woman eats oily fish every day and now has a vitamin D blood level of 40. 'We give supplements of 1,000 international units (IU) a day or we can give an injection of 300,000 IU that lasts for a year. 'The patients respond well,' says Grimes 'but what's needed is a proper controlled, long-term trial and who is going to fund that? Not a drug company.'"

Giving saturated fat another chance. Saturated fat has long held a bad rep and been noted for its potential to contribute to cardiovascular disease. So you might understand why I was a bit skeptical of all the hype surrounding the supposedly miracle-working power of coconut oil, which is composed of saturated fatty acids. However, if there's one thing I have learned as a nutrition student, it is that research has the potential to change our views as we continue to expand our knowledge and make new discoveries. Coconut oil may prevent and alleviate disease. Both research and clinical studies have shown that MCFA may be useful in treating and preventing diseases such as diabetes, osteoporosis, virus-related dieases (mononucleosis, hepatitis C, herpes, etc.), gallbladder disease, Crohn's disease, and cancer. The smaller size of MCFA (compared to LCFA) allows them to be digested more easily, making them ideal for those suffering from digestive diseases. Coconut oil may assist in the absorption and retaining of calcium, thereby benefiting bones. Coconut oil has antimicrobial, antiviral, and antifungal properties. Lipid-coated bacteria and viruses contain a lipid coat which encloses their DNA among other cellular materials. When consumed by humans, coconut oil disrupts the lipid membrane, killing the pathogens without damaging the host or harming health-promoting intestinal bacteria. The antimicrobial properties stem from the monoglycerides and free fatty acids (mainly lauric acid and capric acid) that compose coconut oil.

"THURSDAY, Dec. 17 (HealthDay News) -- In a surprise finding, Canadian researchers report that the immediate effect of the fish oil fatty acids that are good for the heart is a short-term increase in blood fats and the molecules that help them form clots. "We were surprised to find that the acute response has some potentially negative effects in comparison to what you might expect from chronic, long-term intake," said Lindsay E. Robinson, an associate professor of nutrition at the University of Guelph, and leader of the group reporting the finding in the January issue of the Journal of Nutrition. However, the study results shouldn't affect the current recommendation for eating more oily fish to get the omega-3 polyunsaturated acids that reduce the risk of blood clots that can cause heart attacks and stroke, Robinson said. "The recommendation to increase intake is very well-studied, and this doesn't change it," she said. And the effects were seen in a selected group of middle-aged men with metabolic syndrome, a combination of high blood pressure, obesity and elevated blood fat levels, Robinson noted. In the study, eight men had controlled intake of three regimens: high doses of omega-3 fatty acids, low doses of them and just plain water. Robinson and her colleagues measured several blood components involved in clotting, including fats and clotting factors such as plasminogen-activator inhibitor-1 (PAI-1) for the following eight hours. PAI-1 inhibits the destruction of blood clots, so high levels of it in the blood increase the risk of artery-blocking clots. The researchers found that both omega-3 fatty acid regimens increased blood fat and clotting factor activity. But the increase in clotting factor was greater for the higher doses of omega-3 fatty acids than for the lower intakes. Robinson said her group hopes to do further studies of the immediate effects of omega-3 fatty acid intake. "We need to look at the mechanisms, why blood lipid levels go up," she

Reinhold Vieth is frustrated. A thin, bald professor at the University of Toronto's Department of Laboratory Medicine and Patho-biology, Vieth is among the most knowledgeable people in the world on the subject of vitamin D.

After much consideration into this blog's new name in the light of my new direction, the decision has been made. "Free the Animal" Why? First, if you read that post linked above, you know that my health and fitness approach is perfectly in harmony with my philosophical approach; and hence, my approach to politics and all that. In other words, a big part of the reason I have discovered something that truly works; and moreover, is the simplest, most natural, downright fun way of living: that gets you lean and fit; gets you feeling and sleeping great; and gets you looking years and years younger is precisely because I don't believe in the gods of heaven or earth, we evolved over millions of years and are conditioned by survival pressures that in no way include all vegetable diets, gorging on bottled water all day, eating ground grass seeds (grains and derivatives) running on a treadmill or elliptical, or involving ourselves in social schemes and cons that leave us powerless, with no influence, and at the mercy of the crowd and collective (the cannibal pot). Some have a lot of the pieces and do good work. I have all of the major pieces, though acquiring all of the specifics is a lifelong and never-ending journey of discovery. I will focus on essentials and specifics that really matter to me and others living a normal life in pursuit of survival, prosperity and happiness. I will point to other sources that provide more depth in specific areas that are of interest to only some

"(CBS) Your daily cup of java may deliver some unexpected health benefits. Studies have shown it may lower your risk for Type II diabetes and certain types of cancer (colon, mouth and throat), and protect against heart disease and cavities. Dr. Alanna Levine, a primary care physician, said on "The Early Show" researchers aren't sure exactly why coffee has these benefits, but speculated that perhaps the coffee has antioxidant properties.

With all the shortcuts in this menu, why not whip up your main course from scratch? The dory fillets are made extra special by the luscious tomato confit and rum sauce.

If you follow the pyramid of food guide to the dot, you may end up with some health issues in your hands. Why? Because the main goal of the US pyramid is to indiscriminately reduce fat, the good and the bad, while encouraging abundant servings of grains. Unfortunately, study after study has shown that this is not the right path to follow.

Hunger is defined as the "desire to eat caused by a sensation that comes from a lack of food in the stomach". Therefore, we can identify hunger as a biological impulse that moves us to look for food. Studies that have centered on the moment on which we stop ingesting food show that the main reason why we stop eating is lack of hunger. But do we always stop when we are satiated?

I have always wanted two children. I don't know why, this just felt perfect for me.

Scientific evidence points to the fact that eating sugar and fat may stimulate the pleasure at the same body receptors (opioid receptors) that respond to the drug morphine. Thus, eating fat can make us, if not addictive, at least very close to it. And here is why.

Relationships are based on expectations and it also depends on how we fulfill our partner's expectations. There are certain conditions in which we are unable to do so and the most common is the sexual problems caused due to erectile dysfunction. This is characterized by the inability to gain a penile erection naturally or to maintain it and that is why there is a need to Buy Generic Cialis 20mg online to fix up the problem.
