15 Foods to Incorporate for a High-Protein Diet

7. Guava

Fruits are not often considered protein sources, but guava is the most protein-rich of this food option. It also offers the antioxidants vitamin C and lycopene, an antioxidant that can help reduce the risk of cancer. Furthermore, carotenoids in guava, of which lycopene is also one, can protect the eyes against light-induced damage, cataract development, and age-related macular degeneration (ARMD).

There are about 2.6 grams of protein in 100 grams of guava, which still places it below other sources, but certainly makes it worth including if it's available in your area. Coming in at a close second for protein-rich fruits is avocado, which boasts about 2 grams per 100 gram serving, and then apricots, with around 1.4.
