For years, dietary cholesterol was thought to raise our risk of cardiovascular disease. We were told to limit such high-cholesterol foods as red meat, butter, eggs, and shrimp because there was an assumption that the cholesterol in these foods would increase our blood serum cholesterol levels—and high LDL cholesterol is a risk factor for heart disease. But in a report released in February 2015, the Dietary Guidelines Advisory Committee (DGAC) of the United States government stated, “Previously, the Dietary Guidelines for Americans recommended that cholesterol intake be limited to no more than 300 mg/day. The 2015 DGAC will not bring forward this recommendation because available evidence shows no appreciable relationship between consumption of dietary cholesterol and serum (blood) cholesterol, consistent with the AHA/ACC (American Heart Association / American College of Cardiology) report. Cholesterol is not a nutrient of concern for overconsumption.”
Yes, this means what you think it means—you can eat omelets without worry! Shrimp cocktail? Yes, please! It turns out that only 15% of circulating cholesterol in the blood comes from what we eat, according to Dr. Steven Nissen, chairman of cardiovascular medicine at the Cleveland Clinic, who was interviewed by CNN.com after the government’s report was published.
The newer theory about what leads to increased risk of heart disease, according to a report from Harvard Medical School, is chronic inflammation in the body. Inflammation is a necessary immune response to infection or trauma, and is a good thing when it occurs in connection to problems like sprained ankles or if we eat a contaminated food and become sick. But stress, lack of exercise, and eating unhealthy foods on a regular basis–foods that contain chemicals, additives, damaging fats, and refined sugar, for instance–can lead to chronic low-level inflammation in our bodies, which results in slowly damaged organs, poor functioning of our organ systems, rapid aging, and heart disease. Inflamed arteries cause cholesterol in the blood to “stick” and gunk up the works, and this can eventually lead to a heart attack.
The key culprits in the American diet that lead to inflammation? Sugar, refined carbohydrates like white bread and pasta, and low-quality fats that are too high in omega-6 fatty acids, like soybean, corn, and “vegetable” oil. Choose whole grains rather than white stuff; and get your fats from olive oil, seeds, nuts, fish, and avocados (which are all high in anti-inflammatory omega-3 fatty acids) rather than from the omega-6 oils that are used often for commercial deep frying and in processed foods.
You’ll be doing your heart a huge favor.

This is big: a new study has shown that high-fructose corn syrup does in fact cause greater weight gain than sugar, and also leads to dangerous changes in the body. According to timesonline.co.uk:
“Over 10 weeks, 16 volunteers on a strictly controlled diet, including high levels of fructose, produced new fat cells around their heart, liver and other digestive organs. They also showed signs of food-processing abnormalities linked to diabetes and heart disease. Another group of volunteers on the same diet, but with glucose sugar replacing fructose, did not have these problems.
People in both groups put on a similar amount of weight. However, researchers at the University of California who conducted the trial, said the levels of weight gain among the fructose consumers would be greater over the long term.
Fructose bypasses the digestive process that breaks down other forms of sugar. It arrives intact in the liver where it causes a variety of abnormal reactions, including the disruption of mechanisms that instruct the body whether to burn or store fat.”

“At first blush, the notion of eating our way out of huge public health challenges like obesity, diabetes and heart disease may seem an overly simplistic and idealistic fix for complex, multifaceted problems. But health experts say that, in fact, an apple a day does keep the doctor away, and that many studies prove it.”
Nice affirming news from The New York Times. Companies like Safeway are realizing that health care costs are getting out of control, and are now focusing on preventative care. So many of today’s “expensive” diseases–obesity, type 2 diabetes, heart disease, and cancer–are tied to diet and lifestyle choices and are quite preventable. And so, the reasoning goes, if an employer can encourage its workers to eat things like vegetables and whole grains instead of Doritos and McDonald’s, costs for health insurance will ultimately go down or at least stabilize. And it’s working.
The article acknowledges that it’s easier said than done to make dietary and lifestyle changes. There’s so much conflicting info about nutrition out there–which should you listen to?
