Nutritional Gatekeeper: How Big a Role?
For many years, research found that one person in each family called the Gatekeeper controls the majority of food purchased and eaten by all family members. Now some question whether cultural changes are removing gatekeepers’ power.

Although age-related macular degeneration is still not fully understood, experts say it may stem from damage caused by oxidation reactions. A past large study showed that high doses of antioxidant supplements might slow a person’s progression from early to late AMD.
Making Sense of Nutrition Research
Publicity about the recently released results from the Women’s Health Initiative (WHI) on lowfat diets is a good example of the confusion the media causes when headlines seem to contradict earlier research results and common sense.
Flavor: Friend or Foe of Healthy Eating?
Experts say the real reason behind the success, and ultimately the failure, of many weight loss diets is that their limited variety of foods and flavors makes people so bored with the food that they eat less and lose weight.
Do Diet Meals Help?
