Does boiling vegetables remove nutrients?

Yes, boiling vegetables removes nutrients, particularly water-soluble vitamins (C and B vitamins) and some minerals, as they leach into the cooking water, though some antioxidants might become more available. While boiling causes nutrient loss compared to raw or steamed vegetables, it's still better than eating no vegetables at all, and cooking also improves the absorption of other nutrients and makes some compounds more accessible.

Why is boiling water not recommended?

Boiling water isn't used for everything because it only kills microbes, not chemicals like lead or nitrates, which can concentrate; it's energy-intensive, impractical for large volumes, doesn't remove solids (making brown water still unsafe), and doesn't provide residual protection like chlorination. For things like making baby formula or cooking, boiling also doesn't make it pure, and using hot tap water can increase lead exposure, making cold water the better choice for initial use, say the EPA and other sources. 

Why is boiling unhealthy?

Are carrots healthier, raw or cooked?

Carrots are great both raw and cooked; raw carrots offer more fiber and crunch, while cooking (especially steaming or boiling) breaks down cell walls, making the antioxidants like beta-carotene (Vitamin A) more available for your body to absorb, though you'll lose some Vitamin C. For maximum nutrients, eat them both ways, but ensure cooked carrots have a little fat (like olive oil) for better beta-carotene absorption.
 

Which cooking method is healthiest?

The healthiest ways to cook involve minimal added fats and preserve nutrients, with steaming, stir-frying/sautéing, baking/roasting, grilling/broiling, poaching, and microwaving being top methods, especially for vegetables, fish, and lean meats, by using low moisture or quick, controlled heat to retain vitamins, color, and texture. Avoid deep-frying and excessive charring to reduce unhealthy fats and potential carcinogens, focusing on methods that use little to no oil.
 

What is the most nutritious vegetable?
