1. Sweet Potatoes
If you have ever asked yourself, “Are sweet potatoes healthy?”, the answer is a firm yes. Sweet potatoes are a fall produce favorite and are packed with antioxidants like beta-carotene and vitamin C. These nutrients help fight oxidative stress in the body, making them one of the best foods for relieving stress while also supporting overall health.
According to WebMD, sweet potatoes are also loaded with beta-carotene (which the body turns into vitamin A) and fiber. This makes them one of the healthiest vegetables for supporting eye and digestive health.
Still, as with many of the best vegetables, there are pros and cons to how you prepare them. Boiled sweet potatoes have a lower glycemic index than baked or roasted ones, which makes them a better option for people managing blood sugar levels. If you like baked or roasted versions better, serving them with protein or healthy fats can help lessen post-meal blood sugar spikes.
Whether baked, mashed or fried, their flavor is a winner in dishes such as baked candied sweet potatoes or sweet potato cornbread. Cooking can boost the bioavailability of beta-carotene, but overcooking may lower water-soluble vitamins such as vitamin C.

Keep in mind that collard greens contain oxalates, which may contribute to kidney stones and interfere with blood-thinning medications, though such problems are less common among people who eat balanced diets and remain well-hydrated. Cooking them likewise lowers their oxalate levels, and combining this healthy vegetable with other calcium-rich foods improves nutrient absorption.
Besides being a key nutritional contributor among the healthiest vegetables for several reasons, collard greens are also remarkably versatile. Whether sautéed or steamed, they bring a pleasantly earthy and mildly sweet flavor when used in dishes such as Kenya’s sukuma wiki, Brazil’s caldo verde soup, or one-pot meals like Instant Pot collard greens.

Yet its high oxalate content can interfere with the absorption of calcium and iron, which can lead to kidney stones in those who are prone to them. Fortunately, there’s a solution: cooking spinach lightly cuts oxalates considerably and improves iron absorption when it’s eaten alongside other foods rich in vitamin C.
Spinach is at its best when cooked into Indian dishes such as saag paneer or vegan tikka masala, and it can also be eaten raw or cooked into salads, like a wilted spinach salad. If you’d rather not use an entire packet of spinach at once but don’t want it to spoil either, you can freeze it and toss the frozen spinach directly into the pot or pan for tasty dishes such as a spinach omelette.
