Researchers at Tufts University analyzed data from 30,899 U.S. adults who had answered questionnaires on the foods that they ate and the supplements that they took, and were then followed for six years or more (Annals of Internal Medicine, May 7, 2019). A total of 3613 deaths occurred during the study period. The researchers...
Calorie counts listed on food packages or restaurant menus are deceptive because they tell how much energy that food has when it is burned in a laboratory. The number of calories absorbed in your body is likely to be quite different, depending on how the food is prepared and what types of bacteria you...
Mice that have a specific defect in their immune system all become obese (Science, Jul 26, 2019:365(6451)). These mice have defective T cells that are unable to recognize harmful invading germs and allow these germs to survive in their colons. You have about 100 trillion bacteria in your colon that help to control your immune...
The Paleo diet and other high-protein diets may be among the more harmful popular diets recommended for weight loss because they: • raise blood levels of TMAO, a marker for increased heart attack risk (European Journal of Nutrition, July 5, 2019:1–14), and • fail to lower high blood sugar even when they promote weight loss ((Evid...
Recently I reported a study showing that post-menopausal women who store fat primarily in their bellies are at increased risk for having heart attacks, even if they are not overweight (Eur Heart, June 30, 2019). Now another study shows that adults under age 50 who were not overweight and reduced their intake of food...
The Nurses' Health study and The Health Professional's Follow-Up study, two of the largest studies on the subject, show that sugar-sweetened beverages are associated with increased risk for heart attacks, diabetes, obesity and high blood pressure, and the more sugar-sweetened beverages you take in, the more likely you are to suffer from these diseases
Chicken is not more heart-healthful than red meat, according to a new study from Oakland Research Institute. The study showed that chicken and mammal meat caused the same high rises in blood cholesterol levels that predict increased risk for heart attacks, while equal amounts of protein and saturated fats from plant sources resulted in...
A prospective study from nine European countries (European Heart Journal Trial) followed for 12.6 years showed that heart attacks are strongly associated with eating mammal meat and processed meats. Many previous studies have shown that a vegetarian diet is associated with reduced heart attack risk.
Probiotics are live bacteria and yeasts that can live in your body and help to keep you healthy. Probiotics are available in live-culture fermented foods such as yogurt, kefir (a probiotic milk drink), buttermilk, kombucha (fermented tea), tempeh, miso and natto (fermented soybean products), kimchi, sauerkraut, some pickles, and some fermented cheeses.
An unhealthful diet causes more deaths world-wide than any other risk factor, according to the Global Burden of Disease study reported this month. Of the 11 million deaths attributed to dietary factors each year, more deaths were associated with inadequate intakes of healthful foods than with eating too much of harmful foods.
A brilliant and very important breakthrough study shows that restricting mammal meat and eggs markedly lowers blood levels of TMAO. Mammal meat and eggs are rich sources of choline, carnitine and lecithin that are converted in your body to a chemical called TMAO that can damage arteries, which can cause plaques to form and later to break off to cause heart attacks and strokes.
Hundreds of studies done in the last 15 years have shown how your microbiome (gut bacteria) helps you to retain your health, and that what you eat determines the ratio of healthful to harmful types of bacteria in your colon. These bacteria govern your immune system that determines, to a large degree, what diseases you will develop and how long you will live.
Strong data associate eating red and processed meats regularly with increased risk for heart disease, respiratory disease, diabetes, some types of cancers and other diseases, but until now we had no good data to show whether eating small amounts of meat may be harmful. However, this month researchers published a study on 96,000 Seventh-day Adventists which suggests that even small amounts of meat increase risk of death, particularly from heart attacks.
For more than 60 years we have heard that saturated fat and cholesterol may be the driving forces behind the high rate of heart attacks in North America. A new study shows strong statistical links between eating a lot of high-cholesterol animal products -- eggs, meat, poultry, and dairy -- and risk for heart attacks.
A recent study in mice showed that just four weeks on a high-fiber diet helped to prevent dementia in aging mice by protecting their microglial cells from being damaged. The high fiber diet reduced levels of inflammatory interleukin-1 beta, which has been linked to dementia in humans, including Alzheimer's disease.
North Americans almost never suffer from vitamin deficiencies, except for vitamin D, yet more than 50 percent of the population spends more than 30 billion dollars each year for vitamin pills and other nutritional supplements that they do not need. Forty-five percent of those who take vitamin pills believe that they will improve their health, but we have no good evidence that they do.
Osteoporosis or low bone mass affects 55 percent of people over age 50 in the United States, according to the International Osteoporosis Foundation. A study of 1,064 women followed for 15 years shows that not getting enough calcium is associated with smaller spinal bones and weaker spines. You need an adequate amount of calcium to keep your bones strong, but many people take calcium pills when they should be getting their calcium from foods. Calcium pills have not been shown to strengthen bones and they can have many serious side effects.
Our food industry works to bring you more and more ultra-processed foods that have little or no fiber, but there is no debate in the scientific community: you should eat lots of plants that have not had their fiber removed. A review commissioned by the World Health Organization (WHO) of 185 prospective studies and 58 clinical trials, covering 4600 adults, shows that for every 8-gram/day increase in dietary fiber, there was up to a 31 percent decrease in deaths from all causes, a 30 percent decrease in deaths from heart attacks, 22 percent reduced risk of stroke, and a 16 percent reduced risk of diabetes, colorectal cancer and breast cancer.
Dietary sugar is supposed to be absorbed in the upper intestinal tract, but new research from Yale suggests that taking in excessive amounts of sugar can cause some of the sugar to pass through the intestines unabsorbed. This sugar arrives in your colon where it can harm you by keeping healthful bacteria from growing in your colon and encouraging the overgrowth of harmful bacteria.
A recent study from a group of highly-respected scientists shows that the fats in milk are unlikely to cause heart attacks and that fermented milk products such as cheese and yogurt may actually help to prevent heart attacks. Most previous studies on milk have depended on self-reporting, which is known to give inaccurate and often biased results. Instead, this study measured dairy fats in the subjects' bloodstreams to prove exactly how much dairy they had consumed.
North Americans spent more than $936 million on vitamin D pills in 2017, doctors ordered more than 10 million laboratory tests for vitamin D for Medicare patients at a cost of $365 million in 2016, and 25 percent of older adults take vitamin D supplements. A Kaiser Health News investigation recently reported that the man most responsible for the obsession with vitamin D pills, Boston endocrinologist Michael Holick, has been paid hundreds of thousands of dollars by supplement and drug manufacturers, the indoor-tanning industry and commercial laboratories that run blood tests for vitamin D.
A recent study showed that processed soluble fiber added to low-fiber foods led to liver cancers in mice, probably by preventing the liver from clearing bile from the body .
A study from Brazil found that having rats fast for 24 hours on alternate days increased their belly fat and interfered with the ability of insulin to control blood sugar levels. One of the most effective ways to lose weight is "intermittent fasting", but this study suggests that doctors need to be careful about the type of "fasting" they recommend to their patients.
Several recent papers show that diets that restrict all carbohydrate-containing foods can cause diseases and shorten your life. People who eat the most vegetables, fruits, beans and whole grains, which are full of carbohydrates, have the lowest rates of heart attacks and heart disease.
A study in mice shows that a ketogenic diet, where you get most of your calories from fat, may cause diabetes. A keto diet may increase risk for developing diabetes by preventing your body from responding to insulin, presumably by causing fat to be deposited in the liver.
The PURE (Prospective Urban Rural Epidemio.logy) Study, reported at the European Society of Cardiology Congress in Munich on August 28, 2018, concludes that increasing intake of fruits, vegetables, nuts, legumes, fish, dairy and non-processed red meat is linked to reduced death rate and reduced incidence of heart attacks in three data sets. However, I hope that you do not use these results as a reason to increase your intake of meat.
