According to American scientists, eating a variety of healthy foods will improve your overall health, help prevent disease and increase longevity …

1. Salmon

Salmon is one of the best sources of omega-3 fatty acids, which reduces the risk of abnormal myocardial infarction, lowers triglycerides, slows the growth of fat that blocks arteries and lowers blood pressure. There is ample evidence to show that omega-3s can be “brain food” because they can reduce the risk of dementia and cognitive decline.

Most fatty fish are rich in omega-3, but salmon is a healthy food because it is low in toxic substances, such as mercury.

2. Yogurt

This healthy food is an excellent source of probiotics, a “friendly bacterium” similar to the naturally occurring bacteria found in the gut. Probiotics have the function of supporting the immune system, helping the body digest and absorb nutrients in food. Regular consumption of yogurt and other probiotic sources can help boost your overall health, prevent certain cancers and treat a number of conditions like diarrhea, urinary tract infections, and irritable bowel syndrome…

3. Sweet potatoes

Sweet potatoes are one of the nutritious, delicious vegetables. They are a good source of potassium, which helps lower blood pressure and sweet potatoes are also high in vitamin A – important for vision, bone health, reproductive health, cell growth, and maintenance. Sweet potatoes are high in fiber and naturally sweet.

4. Green tea

More and more people are interested in the health benefits of green tea – a food rich in antioxidants. Green tea helps you maintain a refreshing spirit, helps with weight loss, regulates cholesterol levels and prevents the negative effects of sunlight on the skin. Regular consumption of green tea may even help prevent or slow the growth of certain types of cancer.

5. Spinach

This low-calorie green leafy vegetable is a healthy food that is loaded with vitamins and minerals that your body needs. A bowl of spinach contains as much calcium for bones as a cup of milk. It also contains a rich source of magnesium – a mineral that supports the muscles and the cardiovascular system to function effectively, and contains a lot of vitamin A and vitamin E, which support cell health.

6. Tomatoes

Tomatoes are one of the healthiest foods and are more effective when cooking them. Canned tomatoes, ground tomatoes, even tomato sauce are excellent sources of lycopene – an antioxidant that has been shown to reduce the risk of prostate cancer and cardiovascular disease. Tomato products also provide potassium, iron, vitamins A, C, and E.

7. Dark Chocolate

Dark chocolate is a portion of healthy and incredibly appealing food. It provides flavonoid antioxidants, which support cardiovascular health. Just don’t overdo it because chocolate is high in fat and calories. And remember: the darker the chocolate, the higher the level of healthy antioxidants.

8. Oatmeal

Oatmeal is one of the best sources of soluble fiber. Fiber can help lower the level of lipoprotein (LDL) – “bad” cholesterol – and control your blood sugar, which reduces the risk of developing heart disease or diabetes. Oats in the morning may also help you maintain a moderate weight, as soluble fiber helps you feel full.
