 Re: Hawkeyho depresivní septik Trocha vědeckých keců, jak pomocí jídla bojovat s depresí:
If you're feeling cranky, drink water.
True
One of the first signs of dehydration is fatigue, which goes along with depression, Somer says. So tank up before you get dry.
Kristen E. D'Anci, a researcher specializing in nutrition and behavior at Tufts, found that even low levels of dehydration consistently had a negative effect on mood. "Not enough water made people feel irritable, less energetic and often brought on a mild headache," she says. She and her colleagues recommend people drink 2 liters of liquids per day — or more for those who engage in vigorous exercise or live in hot climates. Water is good, but almost any liquid, including caffeinated beverages, will do. Alcohol doesn't count.
Omega 3 fatty acids found in fish help depression.
True
At the NIH, Hibbeln has spent two decades studying the effects of omega-3 fatty acids on depression and other mood disorders. The evidence that eating fish high in omega-3s can help is strong, he says.
"These nutrients are as effective as antidepressants in treating people with clinical depression," Hibbeln says. In fact, the American Psychiatric Assn. recommends that people with major depression consume a daily omega-3 supplement.
However, some nutritionists have gotten carried away by assuming that omega-3s can boost the spirits of people who are feeling just a little down. "When we give antidepressants to people who are a little blue, we see that placebos have an almost equal response," Hibbeln says.
For those with clinical depression, the recommended dose is three 6-ounce servings of salmon, tuna, herring or sardines each week. Mussels and trout are also good, but less so. If you can't stomach that much fish, take the equivalent in pure fish oil that contains DHA and EPA. Expect effects within a month, Hibbeln says.
Conversely, eating foods that inhibit omega-3s can make people feel worse. These include alcohol and foods high in omega-6 fatty acids, such as corn, vegetable and soy bean oils as well as the hydrogenated fats found in processed foods. Olive oil and saturated fats, such as butter, are considered neutral.
Chocolate brings good feelings.
False (almost)
Whatever mood boost chocolate gives you is all in your head, and that's OK, says Pelchat, who has been researching the relationship between chocolate and mood for nearly 20 years.
Chocolate contains many components with the potential to enhance mood, but the chemical effect of each of them is small. "It does have low levels of stimulants, but you can get a lot more from other substances," she says. "The caffeine content is very low, so coffee is better for that kind of kick. The sugar might give a temporary lift, but it's subtle. And the phenylethylamine that people say is supposed to make you feel in love — well, many foods, including salami, are much higher in phenylethylamine."
In North America and parts of Europe, women tend to crave chocolate around their menstrual periods, but in other countries, women crave black licorice. To Pelchat, that suggests that "chocolate is more of a cultural phenomenon than a physical one."
The other reason it may lift mood is because it's really delicious. "Anything we find delicious is part of a system that triggers the reward cascade in our brains," she says. "But what causes that cascade for one person doesn't necessarily do it for another."
