Plus: they're a lot tastier than a multivitamin!
A study by the Louisiana State University School of Public Health found that people who eat a salad a day are more likely to get their recommended daily intake of many essential nutrients.

One cup of spinach gives you 58 micrograms (mcg) of folate.

Disease-fighting power: heart disease, cancer, Alzheimer's, osteoporosis, diabetes, weight, depression

Disease-fighting power: heart disease, cancer, osteoporosis, diabetes, and hypertension
CHUNK LIGHT TUNA
Tuna, one of the best sources of protein (and therefore one of our top salad ingredients), contains no trans fat, and a three-ounce serving of chunk light contains 11 mg of heart-healthy niacin, which has been shown to help lower cholesterol and help your body process fat. University of Rochester researchers determined that niacin raises HDL cholesterol (the good kind) and lowers triglycerides more than most statins alone.
Other nutrients: protein, selenium, and vitamin B12
Disease-fighting power: heart disease and diabetes

Plus: 3 Alternative Oils
Loaded with polyphenols and antioxidants, EVOO (or extra virgin olive oil) is an amazingly healthful dressing base for your salads. But there are other oils with which to top your vegetables and greens that offer similar, if not more, nutritional benefits. Check 'em out!
Made from pressed avocados, this oil is rich in heart-healthy monounsaturated fats that may help improve cholesterol and ward off hunger. It also contains vitamins B and E and bloat-banishing potassium. Add it to your fruit salad for a new twist on a classic dish.
Also known as linseed oil—yes, the stuff you used in art class—this fat contains ALA, an essential omega-3 fatty acid that can aid weight maintenance and may reduce heart disease risks by promoting blood vessel health and reducing inflammation. Drizzle it on top of salads or use it instead of olive oil or mayo when whipping up pestos and tuna salads.
A small Pennsylvania State study found that a diet rich in walnuts and walnut oil may help the body respond better to stress and can also help keep diastolic blood pressure levels down. Walnut oil has a rich, nutty flavor. It contains polyunsaturated fatty acids which may increase diet-induced calorie burn and resting metabolic rate. And walnuts have more omega-3 fatty acids than any other nut. Mix with sherry vinegar, olive oil, cumin, and salt and pepper to make a salad dressing.
