Two studies show that the health benefits of antioxidant-rich foods decrease during storage. Green tea and olive oils stored unopened and not exposed to light or moisture showed dramatic drops in antioxidant activity within six months.
Anecdotal evidence always has pointed toward the phenomenon of the "beer gut" or "spare tire." But studies show alcohol has a greater effect on belly fat in people who consume large amounts of alcohol sporadically than in those who average a single drink a day. People who consumed four or more drinks in one sitting on an occasional basis had the highest levels of abdominal fat in a 2003 study published in The Journal of Nutrition.
A growing number of children have milk or egg allergies, and fewer of them outgrow their conditions, two new studies suggest. Those who manage to overcome allergies do so in late childhood or adolescence, compared with two decades ago, when such allergies were frequently outgrown by age 3. These results may indicate that food allergies are now more potent, researchers noted.
Two separate studies show that overweight children, especially boys, are at a higher risk of heart disease when they become adults. One of the studies estimates that the rate of heart disease in overweight or obese teens will increase by 5% to 16% by the time they turn 50.
Two recent studies examine why online retail companies have traditionally experienced low sales conversion rates. Both came to similar conclusions: E-commerce companies, which spent 29% of their sales budgets on marketing programs last year, lack real knowledge about their customers and rely too much on Web metrics.
