Today’s Headlines: Why Muscle Mass Matters More Than Weight, Why You Should Stop Eating White Bread, and Why You Eat More Calories When You Eat Salty Foods

Body mass index (BMI) may no longer be the best way to measure a person’s health. Recent research has shown that the ratio between muscle and fat is more important. “Men who had poor physical fitness at age 18 were three times more likely to develop Type 2 diabetes in midlife than were those who had been highly fit on the cusp of adulthood. Even men with BMIs that pegged them as “normal healthy weight” in their 50s or 60s were far more likely to develop diabetes if they had shown poor level aerobic conditioning and muscle strength at 18.” The research of this study as well as another study concluded that being physically active and building muscle may benefit your health in the long term.

Foods with a high-glycemic index could be responsible for an increased risk of developing lung cancer. A food that has a high-glycemic index has a high level of carbs that can increase glucose levels in the blood. A new study shows “…those with the highest consumption of GI foods had a 49 percent greater risk for lung cancer and a 92 percent higher risk of developing squamous cell carcinoma of the lung— which makes up 25 to 30 percent of lung cancers.” High-glycemic index foods include white bread and white rice.

There may be a scientific reason you can’t seem to stop eating potato chips. A small study suggested that the salt content of some foods may be the reason why you eat more of it. “Adding salt to the meals increased how pleasant people thought the food was. They also wanted to eat more of the high-salt meals than the low-salt meals (not surprisingly), but that didn’t hold true for the high-fat foods over those low in fat. Those salt cravings seemed to influence how much people ate, too. Salt made people eat 11% more food and calories, regardless of how much fat was in the meal.” So next time you reach for a bag of chips, pour out one serving for yourself before you dig in. (Time)
