New Data on Meat

Researchers followed 536,000 men and women, ages 50 to 71, for an average 16 years and found that those who ate the most meat from mammals and processed meat had a 26 percent greater risk of dying within the study period than those who ate the least.

How Excess Salt Affects You

The common belief is that increasing salt intake increases urination and the more you urinate, the more fluid you have to drink to replace the fluid that you have lost. However, in 2011, these researchers studied Russian cosmonauts in a human space flight simulation program in Moscow, and were astonished to find that the cosmonauts actually drank less water when their daily salt intake was doubled.

Energy Drinks

Energy drinks can raise blood pressure and may cause irregular heartbeats, according to a new study conducted at Travis Air Force Base in California.

Artificial Sweeteners, Dementia and Strokes

People who take one diet soda a day are nearly three times more likely than non-diet soda drinkers to suffer a stroke or to become demented, according to a study published in Stroke (April 20, 2017). Both sugar drinkers and artificial-sweetener drinkers were at increased risk for having smaller brains and advanced brain aging.

Vitamin D Recommendations

Less than six percent of North Americans suffer from vitamin D deficiency, but nearly 20 percent take vitamin D pills. It is true that it is difficult to get adequate levels of vitamin D from sunshine during the winter months, but vitamin D is not a miracle vitamin that treats and prevents all sorts of diseases.

No Amount of Overweight is Healthful

Researchers at Boston University and Harvard reviewed three studies following more than 225,000 adults over age 50, for eight to twenty years, and showed that being even slightly overweight can increase your risk of dying by six percent, and in those who are obese, by a whopping 73 percent (Annals of Internal Medicine, April...

Cheese and Yogurt are OK, but Milk is a High Sugar Drink

Milk is a high-sugar drink. We know that D-galactose, a sugar found in milk, causes the same oxidative damage and chronic inflammation that is associated with diabetes, heart attacks, certain cancers and bone loss.

Best Breakfast

For many years I have recommended oatmeal as the ideal breakfast food. It is filling, does not cause a high rise in blood sugar and is an excellent source of soluble fiber. You can enhance the flavor and nutritional value of your oatmeal by adding your choice of nuts, raisins or other dried fruits,

Eat More Fruits and Vegetables

A review of 95 different studies involving two million people shows that just two and a half servings of fruits and vegetables per day is associated with a 16 percent reduced risk of heart disease, an 18 percent reduced risk of stroke, a four percent reduced risk of cancer and a 15 percent reduced risk of premature death.

Which Vegetable Oils Are Best?

Fats are classified by their chemical structures into saturated, polyunsaturated and monounsaturated types. The chemical stability of a fat is determined by its structure. All fats are made of carbon atoms held together by electrical bonds. These bonds can be single bonds that are stable and double bonds that are far less stable. The stability of a fat or oil depends on the number of double bonds between the carbon atoms. The more double bonds, the less stable the fat.

Pesticides

Many people who want to follow a high-plant diet are concerned about pesticides. The Environmental Protection Agency estimates that 20,000 farmers and their families are poisoned by pesticides each year, but no studies have shown pesticide poisoning from routine consumption of fruits and vegetables.

Research on TMAO

I have reported before on TMAO (trimethylamine N-oxide) that is produced by certain bacteria in your gut when you eat foods that contain lecithin, carnitine and choline, such as meat, eggs and dairy products. High levels of TMAO in the bloodstream have been associated with increased risk for heart attacks, strokes, clots, diabetes and certain cancers.

Convert White Fat Cells into Fat-Burning Brown Fat Cells

In childhood, you have more than 30 billion fat cells in your body and that number remains essentially the same for the rest of your life. You gain weight by filling fat cells with fat and you lose weight by emptying them.

Eat WHOLE Grains, Not Flour

Whole grains reduce risk for overweight, diabetes and heart attacks, whereas refined foods made from flour increase risk for these conditions. Researchers followed 54,871 Danish adults, aged 50-64, for almost 15 years and found that those who ate a lot of whole grains, particularly rye and oats, had far fewer heart attacks

Meat and Colon Cancer: New Studies

This week, a study from Spain adds to the evidence that eating any type of meat (red, white processed, cured or organ meat) is associated with increased risk of colon cancer, and that cooking and processing meat increases risk.

Vitamin D Research

A review of studies written since January 2015 shows that you do not benefit from taking high doses of vitamin D or having very high blood levels of that vitamin. The Institute of Medicine recommends that adults need only 600–800 IU of vitamin D per day and that blood levels of hydroxy vitamin D do not need to be higher than 20 ng per milliliter

Even Small Amounts of Alcohol Can Increase Risks for Cancer and Heart Attacks

The United States Public Health Service says that alcohol kills more than 88,000 people in the United States each year, and has shortened the lives of those who died by an average of 30 years. Alcohol also causes one in 10 deaths among working-age adults aged 20-64 years and the health damage it causes costs $223.5 billion, or $1.90 per drink.

High Protein Diets Do Not Lower Blood Sugar

A major benefit of losing excess weight is that it lowers high blood sugar levels to reduce your chances of becoming diabetic and suffering a heart attack. However, high-protein diets do not lower blood sugar levels as much as normal-protein diets do and therefore do not prevent diabetes as effectively as diets that are not high in protein.

How Gut Bacteria Affect Weight

Since bacteria in your colon eat the same food that you do, what you eat determines which types of bacteria thrive in your colon. These bacteria are a prime driver of how high your blood sugar rises after meals and how many calories you absorb from the food you eat.

Big Sugar Does It Again

n eye-opening new report shows that between 2011 and 2015, Coca-Cola gave more than $6 million a year and PepsiCo gave more than $3 million a year to 96 national health organizations. At the same time, they gave more than $1 million a year to the American Beverage Association, their industry lobbying group, to influence legislation to favor the soda industry and against the interests of public health.

Eat Nuts, Live Longer

People who ate nuts five times a week had a significantly lower rate of heart disease than those who ate less or none. The rate of heart disease decreased by 10 percent for every serving per week of increased intake of nuts.

Big Sugar Paid Harvard to Say that Sugar is Healthful

My faith in several of my Harvard mentors during the 1950s and 1960s has been shattered by an article that appeared this week in JAMA Internal Medicine (September 12, 2016). Cristin E. Kearns, a postdoctoral fellow at UCSF, discovered letters in the archives at Harvard, the University of Illinois and other libraries showing that...

More Reasons to Eat Plants

Two strong studies show that 1) giving people with heart disease a diet that is high in fruits and vegetables and low in red meat is more effective than taking statin drugs in preventing heart attack deaths, and 2) eating red meat regularly increases risk for death from a heart attack.

Healthful Fats

A report from the Nurses' Health Study and the Health Professionals Follow-up Study of more than 126,000 men and women who have been followed for 32 years shows that increasing total fat intake is associated with decreasing risk of death.

Artificial Sweeteners Linked to Higher Blood Sugar Levels

Obese people who have taken aspartame or saccharin in the last 24 hours had higher blood sugar rises after taking sugar than those who had not used artificial sweeteners. Lead author Dr. Jennifer Kuk says, "Our study shows that individuals with obesity who consume artificial sweeteners, particularly aspartame, may have worse glucose management than those who don't take sugar substitutes."

Do Vegetarians Live Longer?

Three recent large studies provide more support for a primarily plant-based diet. Two of the studies compared dietary protein from plants and animals and the third one compared dietary fats from plant or animal sources.

Alcohol Has No Health Benefits

A study from New Zealand showed that 30 per cent of alcohol–related deaths were from cancer, and 60 per cent of those deaths were from breast cancer. One third of these deaths were associated with an average of fewer than two drinks a day.

How Eating Less May Prolong Life

Restricting calories, even in non-obese people, reduces inflammation, helps to prevent cancers and increases autophagy. Autophagy or cellular recycling extends the lives of many different species. Autophagy means "self-eating." When a cell dies, the body has a quick way to break down the dead cell’s parts (protein-making, power-generating and transport systems) into small molecules that can be reassembled to be used for making new cell parts.

Two Clues to the Obesity Epidemic

Certain bacteria in your colon may turn dietary fat into body fat to make you fat, and antibiotics may alter gut bacteria to a larger proportion of the types that make you fat

Fructose is the Worst Sugar

Fructose causes more damage than glucose because it is far more likely to deposit fat in your belly, which causes higher blood sugar levels and increases risk for diabetes, heart attacks and death. Glucose is processed by every cell in your body, but almost all fructose is processed only by your liver where most is converted to fatty triglycerides.
