Apples
When nutritionists coined the phrase ‘an apple a day keeps the doctor away,’ they knew what they were talking about since apples offer a wealth of nutritional benefits. Apples pack minerals, vitamins, a unique flavor, and antioxidants that help lower blood pressure. Even with their basketful of benefits, apples can be planted almost everywhere, including your backyard. Interestingly, more than 7,500 varieties of apples are grown worldwide. However, that is not as impressive as the next item on our list, which comes from the legume family that boasts 18,000 species.
