There’s no substitute for a good healthy diet rich in fruits, vegetables, whole grains, healthy fats (nuts and oils), and low in red meat and unhealthy fats. This good eating pattern is most important for your health. But let’s face it. Many people don’t eat the ideal diet. A multivitamin can provide some insurance against nutritional deficiencies. It’s an inexpensive nutritional insurance policy. For example, it will provide folic acid to help lower the risk of heart disease, colon and breast cancer, and neural tube defects in newborns if taken by pregnant women. It may have iodine, which can help with thyroid issues. It will also have vitamin C to prevent scurvy on your next long cruise!
