1. Blueberry

This berry contains fiber, vitamins and minerals, as well as antioxidants that protect the brain and skin.

2. Wild salmon

As we age, brain function declines, and the omega-3 fats in wild salmon come in handy to protect the brain, skin, eyes, heart, and joints. The American Heart Association recommends eating 12 ounces of fatty fish per week.

3. Greek yogurt

This kind of yogurt has twice the protein content of ordinary yogurt and only half the sugar content. It also has probiotics that are very beneficial to internal organ health. The lactose content is also lower than ordinary yogurt.

4. Coffee

Coffee gets a bad rap, but that may not be the case and the culprit may be the sugar and cream you add to your coffee. Some data show that regular coffee drinkers have a lower risk of dying from heart disease, type 2 diabetes and Parkinson's disease than the general population.

5. Barramundi

This fish is showing up on restaurant menus and is really catching on. It has half the calories of salmon and the same amount of omega-3 fats, making it a nutrient-dense food.

6. Oats

The vast majority of Americans don’t get enough fiber. If you want to supplement this nutrient, eating oats is the simplest and easiest way, and it will also help control your weight.

7. Spinach

This common, cheap, and easy-to-cook green vegetable is a treasure trove of nutrients. The lutein it contains has anti-aging effects.
