Research finding benefits from various foods. From Science Daily:
Researchers report that decaffeinated coffee drinking may benefit liver health. Results show that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes. This suggests that chemical compounds in coffee other than caffeine may help protect the liver. Previous studies found that coffee consumption may help lower the risk of developing diabetes, cardiovascular disease, non-alcoholic fatty liver disease, cirrhosis, and liver cancer.
From Science Daily:
Steve Jobs swore by a fruit diet, as he believed it improved his ideas. And he wasn't wrong: food with high levels of tyrosine, like bananas, peaches and almonds, allow us to think harder and more creatively.
The researchers found that the test subjects who drank orange juice with added tyrosine were better at solving puzzles than those who were administered a placebo. Tyrosine is an amino acid that increases the production of dopamine in the brain, which positively influences our ability to think creatively. It can be found in various kinds of fruit, but also in soybeans, spinach, eggs and cottage cheese.
Done in mice, but interesting. And think of all the people who have promoted grapefruit diets over the years. From Science Daily:
Mice fed a high-fat diet gained 18 percent less weight when they drank clarified, no-pulp grapefruit juice compared with a control group of mice that drank water, a new study demonstrated. Juice-drinking mice also showed improved levels of glucose, insulin and a type of fat called triacylglycerol compared with their water-drinking counterparts.
