Is watermelon a good source of iron? Is sea salt a good source of iodine?

— CHERYL M., Atlanta A: Watermelon is not a good source of iron. Most fruit doesn’t contain any iron, with the exception of some dried fruit, like raisins. Watermelon is a good source of potassium, a mineral needed to help regulate blood pressure. It also contains lycopene, a plant nutrient that is tied to reduced risk of prostate cancer and heart disease. Lycopene is found in other red and pink food like tomatoes, red bell peppers and pink grapefruit. Sea salt does not contain iodine. Some table salt has added iodine; this began at a time when iodine deficiency was more common than it is today. Now you don’t need to worry about getting sufficient iodine through salt because iodine is present in other food and is used as a dough conditioner in bread. Sea salt does contain as much sodium as table salt, so if you are trying to reduce salt intake, sea salt won’t help you do that. Q: Does skim milk have the same amount of tryptophan as whole milk? What about soy milk? — E. DANIELL, Fayette

Yes!  Watermelon is a good source of iron.  Actually, the iron content in watermelon is comparable to the iron content in red meat.  One 6 inch x 1/2 inch slice of watermelon contains 3.0 mg of iron, whereas 3 ounces of beef, pork, or lamb contains 2.3-3.0 mg of iron.
