8 Super Healthy Foods You Must Eat Everyday

Dieting is hard, but eating is easy. Right? That means the easiest way to drop pounds and slim down is to do exactly what you're already doing: eat! Just make sure you're getting in the right foods. What we mean by that is to be strategic: pick the superfoods with the most bang for their buck, and you'll be able to turn around your health with the fewest number of diet changes.

Below, we uncover which nutrient-rich foods deserve a place in your diet daily and how to sneak them into your meals. Perhaps best of all? Most of these foods can be consumed together in one meal: a morning smoothie.

* Spinach

It may be green and leafy, but spinach is no nutritional wallflower. This noted muscle builder is a rich source of plant-based omega-3s and folate, which help reduce the risk of heart disease, stroke, and osteoporosis. It's also one of the 10 salad greens healthier than kale. Bonus: Folate also increases blood flow to the nether regions, helping to protect you against age-related sexual issues. And spinach is packed with lutein, a compound that fights macular degeneration. Aim for 1 cup fresh spinach or 1/2 cup cooked per day.

* Kefir

The 2,000-year-old food's health benefits are not disputed: Fermentation spawns hundreds of millions of probiotic organisms that serve as reinforcements to the battalions of beneficial bacteria in your body. Kefir, a fermented milk product, is one of the most potent, drinkable sources of those probiotics that help boost your immune system and provides protection against cancer. Aim for 1 cup of the calcium and protein-rich goop a day.

* Tomatoes

There are two things you need to know about tomatoes: Red are the best, because they're packed with more of the antioxidant lycopene, and processed tomatoes are just as potent as fresh ones, because it's easier for the body to absorb the lycopene. Studies show that a diet rich in lycopene can decrease your risk of bladder, lung, prostate, skin, and stomach cancers, as well as reduce the risk of coronary artery disease. Aim for 22 mg of lycopene a day, which is about eight red cherry tomatoes or a glass of tomato juice.

* Carrots

Most red, yellow, or orange vegetables and fruits are spiked with carotenoids—fat-soluble compounds that are associated with a reduction in a wide range of cancers, as well as reduced risk and severity of inflammatory conditions such as asthma and rheumatoid arthritis—but none are as easy to prepare, or have as low a caloric density, as carrots. Aim for 1/2 cup a day.

* Blueberries

Host to more antioxidants than any other North American fruit, blueberries help prevent cancer, diabetes, and age-related memory changes (hence the nickname "brain berry"). Studies show that blueberries, which are rich in fiber and vitamins A and C, also boost cardiovascular health. Aim for 1 cup fresh blueberries a day, or 1/2 cup frozen or dried.

* Black Beans

All beans are good for your heart, but none can boost your brain power like black beans. That's because they're full of anthocyanins, antioxidant compounds that have been shown to improve brain function. A daily 1/2-cup serving provides 8 grams of protein and 7.5 grams of fiber. It's also low in calories and free of saturated fat.

* Walnuts

Richer in heart-healthy omega-3s than salmon, loaded with more anti-inflammatory polyphenols than red wine, and packing half as much muscle-building protein as chicken, the walnut sounds like a Frankenfood, but it grows on trees. Other nuts combine only one or two of these features, not all three. A serving of walnuts—about 1 ounce, or 7 nuts—is good anytime, but especially as a postworkout recovery snack.

* Oats

The éminence grise of health food, oats garnered the FDA's first seal of approval. They are packed with soluble fiber, which lowers the risk of heart disease. Yes, oats are loaded with carbs, but the release of those sugars is slowed by the fiber, and because oats also have 10 grams of protein per 1/2-cup serving, they deliver steady, muscle-friendly energy.
