Nuts May Help Curb Unhealthy Eating
Walnuts are a good source of heart-healthy omega-3 fatty acids, and according to a study, they may also make you less hungry for unhealthful foods. Researchers gave 10 obese adults seemingly identical smoothies with the same amount of fat and calories—one containing walnuts, the other walnut flavoring plus safflower oil—for five days in a row. A month later, those same adults received the opposite smoothie. During the walnut week, they reported feeling less hungry. When participants were shown pictures of high-calorie, tasty food after five days of drinking walnut smoothies, their brain scans showed increased activity in a certain area associated with feelings of fullness. Though it doesn’t prove cause and effect, this suggests that the walnuts were causing participants to more carefully consider what they were eating and choose more healthful options. The participants consumed the equivalent of 10 to 12 walnuts a day.
