For some vegetables, the old age adage that 'raw is good' holds true. Cooking some of these vegetables may actually take away the goodness that they can offer, if eaten raw.
Tomatoes and cucumber: They are rich in water content and have essential minerals.
Lettuces : Lettuces, if chewed well are easily digested. They are rich in water and nutrients.
White vegetables: Onion and garlic help lower high blood pressure and cholesterol levels, and reduce the risk for heart disease and stomach cancer. Cooking makes the garlic less potent because heat reduces the amount of health-promoting allicin, so it's best to add garlic just before you finish cooking rather than at the start.
Corn and green peas: While corn must not be a surprise entry in this list, green peas must have surprised you a bit. The truth is they can be eaten raw.
Carrots : When eaten raw, carrots are great for preventing cancer and heart attacks, as well as the commonly known eye sight benefits. However, it is equally nutritious when cooked.
Celery : It is rich in water and minerals. It is again highly digestible and can be eaten raw without any fear.
