• Fresh fruits and vegetables are two of the most important parts of a healthy diet. They provide nutrients for energy and health maintenance, and to combat disease.

    Squashes, like the one sliced in this image, are excellent sources of vitamin A. Vitamin A is very important for eye health and vision, especially seeing in color. Vitamin A also helps maintain healthy skin.

    Sugar cane, stretched out along the back of this image, is actually a type of grass. Raw sugar cane is usually chewed to extract the sweet juice. Raw sugar cane is much healthier than processed sugar! It is a good source of energy and has been linked to easing cold and flu symptoms.

    Yams are the brown vegetables peeking out above the leafy greens. Yams are high in potassium. Potassium helps maintain healthy blood pressure, important for hearts and kidneys.

    Lettuce, cabbage, and other leafy greens are probably the most powerful source of nutrition in the world. One of the many nutrients leafy greens provide is vitamin K. Vitamin K helps regulate blood clotting. This helps wounds to heal quickly. Vitamin K also helps strengthen bones.

    The dark red fruits in the right of this image are sorrel, also called roselle. Roselle is usually not eaten raw, but used to make tea. Like many fruits, roselle is an excellent source of vitamin C. Vitamin C is vital to maintaining a healthy body. It contributes to the creation of strong tissues, such as skin, muscles, and blood vessels. It is necessary for wounds to heal properly and scar tissue to form. Vitamin C is also a natural antihistamine, reducing allergic symptoms such as sneezing, itching, and runny nose.

    Gourds are a type of vegetable. The squash, cucumbers, and long bottle gourd in this image are all gourds. Gourds are a good source of dietary fiber. Fiber helps in digestion, reducing or preventing constipation or irritable bowel syndrome.

    Like the leafy greens and other gourds, cucumbers are full of fiber. They also have a high water content. This helps in digestion, as well as ridding the body of harmful toxins.
