More healthful foods. Coffee plants are being engineered to produce beans low in caffeine. This would be an alternative to using chemicals for making decaffeinated coffee. Beef cattle are being engineered to produce low-fat meat, which would be healthier to eat. Dairy cows and sheep are being genetically altered so that their milk does not contain lactose, which many people cannot digest.
Experiments also are under way to engineer cows to produce milk that is more like human breast milk.
This would mean that women who do not nurse would have a better formula to feed their babies. Vegetables that stay ripe longer. Researchers have engineered tomatoes so that they take longer to rot.
