The Top 16 Superfoods to Incorporate into Your Diet

by Eric Madrid MD

Superfoods are a group of foods rich in vitamins, minerals, and plant-based nutrients with antioxidant properties called phytonutrients. Corporate food companies have gone to great lengths to create and market foods that have little to no nutritional value, what we usually refer to as “junk food”. The products are created by food scientist and designed to be addicting, and it’s worked—many people in the United States and a growing number of countries around the world are eating processed foods, which increases the risk for many diseases.

Ideally, one should focus on eating a diet full of fruits and vegetables. Adding superfoods is part of the equation and can help you on your journey towards health and happiness.

Zenbu Shake

Zenbu means “everything” or “all” in Japanese. Zenbu meal replacement powder is so named because it contains a wide variety of vitamins, minerals, and phytonutrients, which provide quality, high-grade nutrition. Many consume Zenbu for breakfast as it helps stabilize blood sugar. Zenbu also contains protein, trace nutrients, digestive enzymes, prebiotics, and probiotics.  Each serving is only 110 calories, making it a great choice for those wanting to shed a few extra pounds.

Maqui Berry (Aristotelia chilensis)

Maqui Berry is a deep purple fruit that grows wild in the southern parts of Chile. It is harvested for commercial use by the Mapuche Indians and has powerful antioxidant properties. Its ability to protect against oxidation comes from its high content of phenolic acids, flavonoids, and anthocyanins—specifically delphinidins, the strongest antioxidants of all anthocyanins. A 2017 study in Food & Function demonstrated that maqui berry, when consumed with a high-fiber diet, maintained high-level antioxidant capacity.

Maqui berry has the following:

  • Anti-inflammatory properties inhibit COX-2, according to a 2017 study. This is the same enzyme that pharmaceutical drugs such as celecoxib (Celebrex) target.

Bee Propolis

It’s commonly known that bees make honey—some may also be familiar with royal jelly, a common supplement made from a secretion that worker bees produce.  However, few know that bees also make propolis, a substance made by extracting specific ingredients from plants, beeswax, and flowers.  Propolis is also known as “bee glue”.

Propolis comes from the Greek words pro, which means “at the entrance to,” and polis, which translates to “community” or “city”.  Propolis is the glue used to keep a beehive together, and it has many substances within it.  Cardol and quercetin are two of many active ingredients found in bee propolis—these substances help provide its medicinal benefits.

The Incas of South America used propolis to fight fevers while the Greeks and Romans used it to heal wounds.

Health benefits of bee propolis:

  • Lower blood sugar levels in diabetics, according to a 2017 study in the Journal of Integrative Medicine
  • Protection against diabetic kidney disease has been demonstrated using animal models
  • Antibacterial and antifungal properties

  • May protect against dental cavities
  • A 1995 study showed a reduction in upper respiratory infections in children
  • Lowers total cholesterol levels in those with diabetes
  • Killed melanoma cancer cells in a laboratory study
  • Killed colon cancer cells in a laboratory study in 2017

While a few studies have shown bee propolis may be active against certain types of cancer cells, no human studies have been done to show any anti-cancer benefit.

Bee Propolis can be taken in supplement form, as an oral spray or topically on wounds to help prevent infection.

Directions: Take as directed on the label


Spirulina is an easily digestible nutritional supplement, which belongs to a family of blue-green algae and can be taken in a pill or powder form. Spirulina comes from a type of bacteria scientists call cyanobacterium, specifically arthrospira platensis.  Learn more about spirulina.

  • Good source of zinc, which is important for skin health, a strong immune system and memory
  • Good source of B vitamins, which is important for nerve, brain, and heart health.  Since those who consume a vegetarian diet tend to lack vitamin B12, daily supplementation with spirulina can provide up to 60 percent of the recommended daily allowance (RDA) requirement for vitamin B12.
  • Contains gamma-linolenic acid (GLA), an essential fatty acid found in vegetables. It’s considered the healthy omega-6 oil and has anti-inflammatory benefits.
