Two new studies add to the huge body of research showing that perhaps the most important dietary recommendation is to eat lots of fiber, which is found in plants. You keep on gaining health benefits until you reach at least 25 to 29 grams of fiber per day.
North Americans eat far more fat than they need, primarily from the vegetable oils that are added to just about every packaged food or fast food meal you can buy, and from our tendency to cook most of our foods in fat. It is harmful to take in a lot of fats from vegetable oils because excessive fat intake can cause high insulin levels and insulin resistance, which can cause diabetes.
Egg yolks are among the richest food sources of cholesterol, and almost 100 million North American adults have high blood cholesterol levels, signifying increased risk for heart attacks. Most of the cholesterol in your body is made by your liver and less comes from the food that you eat.
In a recent study of time-restricted eating, a group of 19 people with metabolic syndrome (also called pre-diabetes) ate their usual meals but ate only between 8AM and 6PM (10 hours) and took in no calories during the other 14 hours each day.
Researchers at the U.S. Centers for Disease Control and Prevention (CDC) found that for every five percent increase in calories from ultra-processed foods, there is increased risk for heart attacks and strokes. Taking in 70 percent of calories from processed foods doubles heart attack risk factors.
Two companies -- Impossible Foods and Beyond Meat -- dominate the market for plant-based burgers that taste like meat. A major concern is that these products have not been tested for long-term safety.
It is well-known that taking large doses of the fat-soluble vitamins -- A, D, E and K -- can harm you. You may also be harmed by large doses of the water-soluble B vitamins or vitamin C.
Don't believe the recent headlines suggesting that people can continue to eat their usual amounts of meat without suffering any increase in risk for illness or premature death.
A surprising study from the UK shows that vegetarians and pescatarians (those who eat fish but not meat) appear to be at increased risk for suffering bleeding strokes, even though they are at reduced risk for heart attacks and are not at increased risk for clotting strokes.
The various ketogenic diets that severely restrict all carbohydrates and replace them mostly with fats are associated with increased risk for non-alcoholic fatty liver disease or NAFLD. NAFLD can lead to diabetes, heart attacks, strokes, liver cancer and other cancers.
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 a food produces 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.
