Tomatoes provide many health benefits as they contain lycopene which can reduce the risk of several cancers, and vitamins A, C and K. China, India and the United States are the top tomato producing countries worldwide. Tomatoes are grown globally, including in California under irrigation for both fresh and processed products. While tomatoes are technically a fruit, they are often considered a vegetable, and they grow on vines unlike carrots which rabbits like to eat.
