6. Amaranth
The Aztecs mixed this nutty-flavored grain with human blood to build stamina and strength. You can enjoy similar benefits by consuming the cereal version mixed with kefir. “Amaranth is one of the few grains that is a ‘complete protein,’ meaning it has all eight essential amino acids,” says Grotto.
“It’s also rich in the antioxidant squalene, which studies have shown to inhibit prostate cancer.” Some researchers have also found that it’s uniquely effective at reducing LDL (bad) cholesterol.
Pro tip: Boil and serve amaranth instead of rice, or toast and sprinkle it on healthy salads.
