Here is what my boys told my daughter:
• Orange and yellow vegetables and fruits are good for your eyes, so if you want to see a baseball pitch coming your way or be able to read at night, you should eat a lot of pineapple, yellow peppers and yellow summer squash.
• Blue and purple fruits and vegetables such as blueberries, blackberries, plums, eggplant and purple carrots have been shown to improve memory. If you want to remember all the things that Mom forgets, you should keep eating blue and purple foods.
• Red foods, and unfortunately not the synthetic-dyed ones, support your heart (by decreasing heart disease risk, preventing hardening of blood vessels and reducing inflammation). So eat lots of raspberries, strawberries, tomatoes and watermelon to help your heart pump.
• Green vegetables are Mom’s favorites. They have been shown to help prevent cancer and other diseases, keep our blood healthy, and support the immune system that keeps us from getting sick. By keeping our blood healthy, green veggies give us energy, so eat lots of them if you want to keep up with your big brothers!
There are obviously more scientifically accurate reasons to eat your colors, but I thought my boys did a pretty good job. Life is colorful right now. The farmer’s markets are overflowing with yellow, orange, red, green and blue foods, so it couldn’t be simpler to eat the rainbow. And as I pointed out to my boys, it turns out it is not premature to teach a 1-year-old about nutrition. They just rolled their eyes.
