TIPS:Most Surprising Unhealthy Foods

#20 Couscous

Perhaps given a healthy reputation because it is popular with vegetarians, couscous is made of refined wheat and is no more nutritious than plain white pasta. Try whole wheat couscous or quinoa for a healthier side dish.

 

#19 Frozen Yogurt

Most "frozen yogurt" isn't yogurt at all, but a sugary ice-cream substitute. Even when they do use real yogurt, it is often heat-processed, killing the beneficial bacteria in the yogurt. For a healthy frozen treat, get some full-fat Greek yogurt, preferably naturally-sweetened with fruit or honey, and toss it in the freezer.

#18 Diet Soda

No calories, no problem, right? Not necessarily. Not only are diet sodas nutritionally deficient, but the artificial sweeteners can increase your risk of heart disease and diabetes. If you crave a sweet beverage, better to occasionally treat yourself to a naturally sweet treat like fresh fruit juice.

 

#17 Trail Mix

While trail mixes start with healthy ingredients like nuts and dried fruit, they often include nuts coated in salt, fruit that's been dipped in sugar, and junk food treats like chocolate and peanut butter chips. For a healthier alternative look for fruit and nut mixes without added salts and sugars.
