6. Eat wild blueberries for breakfast.
These vitamin-and-fiber-packed berries are a surprisingly good source of manganese, which plays an important role in bone health and metabolism. And as the girl at the famer's market likes to remind you, they're bursting with antioxidants (specifically, cancer-preventing anthocyanins, a type of polyphenol).

Older adults who drank wild blueberry juice every day performed better on memory tests and were in better spirits than those who drank a placebo, found psychiatrists at the University of Cincinnati.

Several studies have shown a link between living longer and having sex more often (men) and having enjoyable sex (women). While researchers haven't yet been able to parse out whether sex extends life spans or whether those who have healthier love lives have healthier lives in general, at least one large study of more than 3,500 people showed that regular sex helps us look four to seven years younger.
8. Eat fish for dinner.
A study by researchers at Ohio State University found that boosting the ratio of omega-3 fatty acids compared with other oils in our system can help lengthen our telomeres, the caps at the ends of our chromosomes, which shrink with age. This means that a regular diet of cold-water fish (or fish oil supplements) could lower the risk for age-related diseases like coronary heart disease, type 2 diabetes, arthritis and Alzheimer's disease.

The herbs and spices can help fight infection and chronic diseases (and the noodle dish is usually swimming in unhealthy oil).
