Nutritionally speaking, there is no such thing as a superfood.
The term was coined for marketing purposes to influence food trends and sell products.
The food industry bestows the superfood label on nutrient-rich foods with a supposed capacity to positively affect health.
Though many foods could be described as super, it’s important to understand that there is no single food that holds the key to good health or disease prevention.
But since the term “superfood” doesn’t seem to be going anywhere anytime soon, it may be worth taking a closer look at some healthy options.
Here are 16 foods that may be worthy of the esteemed superfood title.
1. Dark Leafy Greens
Dark green leafy vegetables (DGLVs) are an excellent source of nutrients including folate, zinc, calcium, iron, magnesium, vitamin C and fiber.
Part of what makes DGLVs so super is their potential to reduce your risk of chronic illnesses including heart disease and type 2 diabetes (1Trusted Source, 2Trusted Source).
They also contain high levels of anti-inflammatory compounds known as carotenoids, which may protect against certain types of cancer.
Some well-known DGLVs include:
- Swiss chard
- Collard greens
- Turnip greens
Some DGLVs have a bitter taste and not everyone enjoys them plain. You can get creative by including them in your favorite soups, salads, smoothies, stir-fries and curries.
