Does boiling apples remove nutrients?

Does boiling beans remove nutrients?

One study shows that canned beans have lower phytate levels than dried, un-soaked beans, indicating that the canning process (which may include soaking, or blanching or pressure cooking at high heat for a short period of time, depending on which process is used) is also effective in reducing anti-nutrients.

What changes occur as vegetables are cooked?

Cooking changes a vegetable’s texture, flavor, color, and nutrient content. High temperatures make vegetables tender and enhance flavor. In addition, cooking usually makes vegetables safer to eat by killing microbes. Over- cooking, however, will cause texture, flavor, color, and nutrient content to deteriorate.
