"It's probably not harmful to take a multivitamin if you want to, you may be wasting your money."

Dieticians say you'll get more bang for your buck by shifting your focus from taking a pill to making smarter food choices.

For example, one cup of cantaloupe gives you more than 100 percent of your vitamin C needs.

"Oranges have lots of vitamin C, beans have lots of protein, broccoli has lots of vitamin C, dark green leafy vegetables have lots of folate and calcium."

Experts say stock your cart with the colors of the rainbow: red, orange, yellow, green, blue, and purple.

Ginnie Collins, Clinical dietician
"Nature provides us with all these colorful vegetables and fruits, and if we eat them every day than we're going meet the majority of the needs that we have."

So experts advise, to stay healthy, keep a colorful cart.
