...good news is that these blood-sugar spikes and crashes are easy to regulate. Blood sugar will rise and fall quickly if, for example, a person eats an easily digested meal of only white bread. Eat some vinegar with the bread, however, and the impact is dampened: The vinegar slows digestion, helping to keep blood-sugar levels more even. The same thing happens if a person takes his bread with nuts or with a glass of wine. (The dampening effect of alcohol reverses after more than a couple units, which may help to explain why moderate drinking, but not heavy...
Want to know how many cheeseburgers you'd have to eat before they start doing damage to your body? The answer, according to a review of new dietary research, is just one. Just one high-fat, high-sugar meal can trigger a biochemical cascade, causing inflammation of blood vessels and immediate, detrimental changes to the nervous system, according to the paper, published this week in the Journal of the American College of Cardiology. And just one healthy meal helps return your body to its optimal state. "Your health and vigor, at a very basic level, are as good as your...
...including glucose (sugar), lipids (fats), and amino acids (the building blocks of protein). If your meal happens to be junk food - say, a processed bun with a cheap beef patty, French fries and a Coke - the rush of sugar causes something called "post-prandial hyperglycemia": a big spike in blood-sugar levels. Poor diet in the long-term leads to hypertension and buildup of gunk in blood vessels that increases heart-attack risk. But there are short-term effects too. "People don't understand this, even most physicians," says O'Keefe. Tissue becomes inflamed, just as it does when infected...
...example, the previously mentioned drop in insulin that leaves a person hungry not long after eating a heavy meal. Studies suggest that fatty, sugary foods promote excretion of the stress hormone cortisol, which seems to further stimulate appetite for calorie-dense foods. And the big post-meal spikes in blood sugar are more likely in people who don't exercise or those who carry weight around their abdomen. All of it makes it tough for people to stop eating junk food once they're in the habit. "The more you eat it the more you crave it. It becomes...
...record, the main winners in the dramatic acting categories were Daniel Day-Lewis (in There Will Be Blood) and Julie Christie (Away from Her). Johnny Deep (Sweeney Todd) and Marion Cotillard (La Vie en Rose) won for comedy or musical. The Supporting prizes went to Javier Bardem (No Country for Old Men) and Cate Blanchett (I'm Not There). For you xenophobes keeping score, yes, that's five foreign winners - two Anglos, a Frenchwoman, a Spaniard and an Aussie - and an American who lives in France. All these winners are shoo-ins for Oscar nominations. So is Juno, the indie...
