How Does Cooking Affect Nutrients in Veggies?

Lifestyle No Comments »

This week Reactions explores the chemistry and science that goes on to the nutrients when you cook vegetables. Vegetables are chock-full of essential vitamins and minerals, but how should you eat them to get the most nutritious bang for your buck? Raw? Sauteed? Frozen? You might want to eat those fresh green beans right away, for one — flash-frozen green beans kept for months have up to three times more vitamin C than week-old beans kept in the fridge. And did you know that oil-based dressing and avocados can help you absorb more nutrients from that kale salad.
