If you love potatoes, you’ll be happy to know that one type has made this list, sweet potatoes. Usually, people only eat them during the holiday season or other exceptional times throughout the year. However, it might not be a bad idea to include them in your diet more often to improve your immune system.

You don’t even need to eat a lot of sweet potatoes because 5-inches of one potato contains 100% of the vitamin A you need in your daily diet.
