Buy canned tomatoes over fresh
All tomatoes have cancer-fighting properties, but the most nutritious tomatoes in the supermarket aren’t in the produce aisle! Processed tomatoes are the richest known source of lycopene, because of their concentrated state. When buying fresh, look for smaller size and deeper color; you’ll get more nutrients.
If you have a choice, deep red tomatoes have more antioxidants than yellow, gold, or green tomatoes.
