This leafy green has a peppery flavor and makes a great addition to any summer salad. Watercress tops the Centers for Disease Control and Prevention (CDC) list of “powerhouse” fruits and vegetables because it was found to be the most nutrient dense food.

Watercress has only 11 calories per 100 grams, and is an excellent source of ascorbic acid (vitamin C), containing more vitamin C than an orange weight for weight. It is also an excellent source of milk, iron, folate, and vitamins A, B6, and K. A study in the American Journal of Clinical Nutrition found that eating a daily portion of watercress can significantly reduce DNA damage to blood cells that is considered an important trigger in the development of cancer.

Popular in the Middle East, Europe, Asia, and South America, Fava beans are a healthy summer delicacy, available in produce stores from late spring though most of the summer season. These legumes, also known as broad beans, are a great source of lean protein, as well as a good source of potassium, magnesium, zinc, and vitamins B1, B6, and K. They are also rich in fiber and have no cholesterol or saturated fat. Fava beans can be served raw or cooked, though the pods must first be blanched.

Turns out this summer classic is indeed the perfect choice for a healthy snack after a long day in the sun. As its name implies, watermelon is almost 92 percent water, making it a great source of hydration in hot weather. It only has 88 calories in a two cup-sized serving and one gram of fiber, which slows digestion and helps keep you feeling full longer.

With dark leaves and red, purple, or yellow stalks, Swiss chard is a leafy green vegetable that is also included on the CDC list of “powerhouse” fruits and vegetables for being packed with nutrients and vitamins.

Studies have shown that chard can be especially beneficial to diabetics because it has unique benefits for blood sugar regulation. The vegetable contains syringic acid, which inhibits the activity of the enzyme alpha-glucosidase (an enzyme that usually breaks down carbohydrates into simple sugars). Swiss chard also has a good amount of fiber (3.5 grams per cooked cup), protein, antioxidants, calcium and Vitamin K. As an added bonus, a cooked cup only has 35 calories. Swiss chard can be eaten raw in salads, or cooked and sauteed.

Generally underrated, radishes are actually very good for you. This root crop is low in calories, as well as saturated fat and cholesterol, due to its high water content (about 90%). Radishes are also a great source of vitamin C, fiber, potassium, and folate. They are natural diuretics and are very filling (keeping you from needlessly snacking.) They are also good for the liver as natural detoxifiers and can even be used to treat bee stings and insect bites because of their anti-pruritic properties. Radishes are also included on the CDC’s list of “powerhouse” fruits and vegetables.

Also found on the CDC’s list of “powerhouse” fruits and vegetables, arugula is a leafy green that is in season from late spring through September.

In fact, it contains 14 percent of your daily vitamin K requirements. This popular green also contains lutein, an antioxidant that helps maintain healthy eyes, skin, and heart.

Peaches are a pretty tasty and healthy summer snack: They are low in calories (with a typical peach only containing 68 calories) and a great source of fiber. The fruit also contains 10 different vitamins, including vitamin C, an antioxidant and tissue-builder, and also vitamin A, important to healthy vision. Peaches are also a good source of vitamins E and K, potassium, magnesium, and calcium.

Peach season is at its peak in July and August. Try grilling them to make an extra special treat.

Zucchini is a popular summer squash that can be served raw, grilled, rolled, or diced. It has only 20 calories per cup, no fat or cholesterol, while providing 35% of your daily-recommended vitamin C.

These luscious, sweet little red berries are a great source of fiber: one cup has 8 grams of fiber, some of which is soluble in the form of pectin, which helps lower cholesterol. They are also a source of antioxidants, vitamins and minerals, including potassium and vitamin C.
