The Sugar Conspiracy - Ian Leslie
For at least the last three decades, the dietary arch-villain has been saturated fat. When Yudkin was conducting his research into the effects of sugar, in the 1960s, a new nutritional orthodoxy was in the process of asserting itself. Its central tenet was that a healthy diet is a low-fat diet. Yudkin led a diminishing band of dissenters who believed that sugar, not fat, was the more likely cause of maladies such as obesity, heart disease and diabetes. But by the time he wrote his book, the commanding heights of the field had been seized by proponents of the fat hypothesis. Yudkin found himself fighting a rearguard action, and he was defeated.
Landmark Study: Mediterranean Diet Cuts Heart Risks
The study lasted five years and involved about 7,500 people in Spain. Those who ate Mediterranean-style with lots of olive oil or nuts had a 30 percent lower risk of major cardiovascular problems compared to others who were told to follow a low-fat diet. Mediterranean meant lots of fruit, fish, chicken, beans, tomato sauce, salads, and wine and little baked goods and pastries.
What Really Makes Us Fat - Gary Taubes
One diet was low-fat and thus high in carbohydrates. This was the diet we’re all advised to eat: whole grains, fruits, vegetables, lean sources of protein. One diet had a low glycemic index: fewer carbohydrates in total, and those that were included were slow to be digested — from beans, non-starchy vegetables and other minimally processed sources. The third diet was Atkins, which is very low in carbohydrates and high in fat and protein.
The results were remarkable. Put most simply, the fewer carbohydrates consumed, the more energy these weight-reduced people expended. On the very low-carbohydrate Atkins diet, there was virtually no metabolic adaptation to the weight loss. These subjects expended, on average, only 100 fewer calories a day than they did at their full weights. Eight of the 21 subjects expended more than they did at their full weights — the opposite of the predicted metabolic compensation.
Why the Campaign to Stop America's Obesity Crisis Keeps Failing - Gary Taubes
There is an alternative theory, one that has also been around for decades but that the establishment has largely ignored. This theory implicates specific foods—refined sugars and grains—because of their effect on the hormone insulin, which regulates fat accumulation. If this hormonal-defect hypothesis is true, not all calories are created equal, as the conventional wisdom holds. And if it is true, the problem is not only controlling our impulses, but also changing the entire American food economy and rewriting our beliefs about what constitutes a healthy diet.
Oddly, this nutrient-hormone-fat interaction is not particularly controversial. You can find it in medical textbooks as the explanation for why our fat cells get fat. But the anti-obesity establishment doesn’t take the next step: that fat fat cells lead to fat humans. In their eyes, yes, insulin regulates how much fat gets trapped in your fat cells, and the kinds of carbohydrates we eat today pretty much drive up your insulin levels. But, they conclude, while individual cells get fat that way, the reason an entire human gets fat has nothing to do with it. We’re just eating too much.
New study is wake-up call for diet soda drinkers - Ryan Jaslow
Just how does diet soda make you fat? The other study may hold the answer. In it, researchers divided mice into two groups, one of which ate food laced with the popular sweetener aspartame. After three months, the mice eating aspartame-chow had higher blood sugar levels than the mice eating normal food. The authors said in a written statement their findings could "contribute to the associations observed between diet soda consumption and the risk of diabetes in humans."
But how?
"Artificial sweeteners could have the effect of triggering appetite but unlike regular sugars they don't deliver something that will squelch the appetite," Sharon Fowler, obesity researcher at UT Health Science Center at San Diego and a co-author on both of these studies, told the Daily Mail. She also said sweeteners could inhibit brain cells that make you feel full.
So if sugar soda is no good, and diet soda isn't either - what should we be drinking?
Dr. Hazuda told the Daily Mail, "I think prudence would dictate drinking water."
Mystery Ingredient in Coffee Boosts Protection Against Alzheimer's Disease, Study Finds - sciencedaily.com
A yet unidentified component of coffee interacts with the beverage's caffeine, which could be a surprising reason why daily coffee intake protects against Alzheimer's disease. A new Alzheimer's mouse study by researchers at the University of South Florida found that this interaction boosts blood levels of a critical growth factor that seems to fight off the Alzheimer's disease process.
The findings appear in the early online version of an article to be published June 28 in the Journal of Alzheimer's Disease. Using mice bred to develop symptoms mimicking Alzheimer's disease, the USF team presents the first evidence that caffeinated coffee offers protection against the memory-robbing disease that is not possible with other caffeine-containing drinks or decaffeinated coffee.
A Good Night’s Sleep Isn’t a Luxury; It’s a Necessity - Jane E. Brody
A good night’s sleep is much more than a luxury. Its benefits include improvements in concentration, short-term memory, productivity, mood, sensitivity to pain and immune function.
If you care about how you look, more sleep can even make you appear more attractive. In a study published online in December in the journal BMJ, researchers in Sweden and the Netherlands reported that 23 sleep-deprived adults seemed to untrained observers to be less healthy, more tired and less attractive than they appeared to be after a full night’s sleep.
Perhaps more important, losing sleep may make you fat — or at least, fatter than you would otherwise be. In a study by Harvard researchers involving 68,000 middle-aged women followed for 16 years, those who slept five hours or less each night were found to weigh 5.4 pounds more — and were 15 percent more likely to become obese — than the women who slept seven hours nightly.
