The Doctrine Of Signatures tells us that food indicates how it contributes to the human body by how it looks. Tomatoes look like your heart,are red like your heart and have 4 chambers just like your heart. A high dietary intake of tomatoes significantly reduces cholesterol levels,due to their high levels of niacin and potassium. VitaminB6 and folate are both needed by the body to covert a dangerous chemical called homocysteine into benign molecules,to protect damage to blood vessel walls,and reducing risk of heart attack,stroke and blood clots. All of these nutrients work together to make tomatoes a truly heart-healthy food.
