5. The Icelandic Approach: Fatty Varieties of Fish.
Iceland is known for its long dark winters and short cool summers. Although people do not get enough sun and cannot enjoy warm weather even in the summer, the percentage of people suffering depression is the world’s lowest. The reason is the menu that includes plenty of seafood, especially fatty sorts of fish, such as sardines, scomber, and, though a bit more expensive, salmon.

6. The Sardinian Approach: Drinking Red Wine.
There are a lot of Sardinians who are 100 years old! One or two glasses of red wine is their main secret. Red wines are full of antioxidants. They protect our heart and blood vessels, neutralize “bad” cholesterol and increase the level of HDL (high-density lipoprotein), which is also known as the “good” cholesterol. Red wine, just like any other alcohol-containing drink, should be consumed in moderation. One glass of red wine per day is all most people need to maintain their cardiovascular system. You can replace red wine with grape juice.
