Health benefits of 20 common vegetables

The UN General Assembly named 2021 the International Year of Fruits and Vegetables (IYFV). The designation brings with it a chance to raise awareness around the world of the essential role fruits and vegetables play in food security and nutrition.

Plant-based meal delivery service Thistle compiled a list of 20 common vegetables with serious nutritional benefits using reliable journal studies and news articles. From the magnesium-rich sunchoke, which can help you fall asleep faster and stay asleep longer, to the beta carotene rich carrot, which can stave off eyesight decline, the options are endless for using vegetables to improve your overall health and well-being.

It’s no secret that eating your vegetables is a key component of good nutrition and health. From vitamins A, C, and E to magnesium and phosphorous, veggies are a major source of essential nutrients, minerals, and vitamins.

The vegetable kingdom extends far beyond lettuce and tomatoes to many flavorful and nutrient-dense options. All of these can be prepared and incorporated into a diet that makes staying healthy delicious and fun rather than a tasteless obligation. Many chefs around the world are taking note—from Los Angeles-based chef Matthew Kenney, whose plant-based empire is wildly popular in the health-conscious city, to London chef Yotam Ottolenghi, who uses everything from cauliflower to artichokes as the stars of his meals.

Vegetarians and vegans, in particular, are wise to load up on spinach. The leafy green is full of iron, which is also commonly found in meat and animal products.

Chard may be a relative of beets, but it’s grown for its leaves rather than its roots. It is an excellent source of potassium, which helps reduce blood pressure and water retention, and works well for regulating fluid balance and nerve signals. In some studies, subjects were found to have a 21% lower risk of stroke with every 1.64 grams of potassium they ate. Chard leaves can be chopped for salads, added to omelets, tossed in a smoothie, cooked in a stir fry or soup, and whole leaves can even be used as a wrap, taco-style, or added to sandwiches.

Broccoli is a famously healthy vegetable. The National Cancer Institute has reported on studies conducted to determine if broccoli may help prevent cancer. Broccoli belongs to the cruciferous vegetable family, which release indoles and other biologically active compounds when they are broken down in the body. Some research has shown that these can inhibit the development of cancer in certain organs. Broccoli is particularly delicious grilled with olive oil and topped with garlic.

Slice up your green peppers and enjoy them roasted in a salad, or just eat raw with hummus or another dip.

Potatoes can help with blood sugar control. This is because potatoes contain a resistant starch that helps lower insulin resistance, which in turn helps blood sugar control.
