7. Garlic and onion
I know, I know, you don’t like garlic and onion, but you can’t even imagine what amazing health benefits they boast.
Not only garlic and onion help to boost your immune system, but they also help you prevent serious disease, including stomach, colorectal, breast and prostate cancer.
Unless you have a date today, add some onions and garlic to your green salad for that extra immune boost.
