You can find a bounty of tropical fruit in your local supermarket, even if you live in a cold climate, including:

• Avocados. Although frequently mistaken for a vegetable, the avocado is actually a member of the pear family. Avocados are rich in vitamins A, C, and E. Ripe avocados can be refrigerated for up to five days.

• Bananas. Bananas are a great source of potassium, an essential electrolyte, as well as magnesium and vitamin B6.

• Kiwifruit. Kiwi are rich in vitamins A and C and contain nearly as much potassium as bananas. Their fuzzy skins contain valuable antioxidants and can also be used in marinades for tenderizing meats.

• Mangos. Like other orange-colored produce, mangos are packed with beta-carotene.

• Papayas. Papayas are loaded with papain, an enzyme that promotes digestion and has been shown to protect the stomach from ulcers. Papayas are also rich in vitamins A and C, and have an abundance of natural sugars. Papayas can also help reduce acidosis, acne, heart disease, tumors, ulcers, and blood disorders.

• Pineapple. A great source of potassium, calcium, iron, and iodine, fresh pineapple is worth the hassle required to prepare it for smoothies. Using a strong knife, slice off the top and bottom of the pineapple so it sits flat on your cutting board, and then slice off the peel.
