In reference to “Boosting boron could be healthful,” it’s important to note that there’s no risk in aiming for a high-boron diet. Eighty percent of Americans fall short when it comes to dietary recommendations for fruit, nut, and legume intake. Eating four servings of fruit and a handful of nuts per day could bring boron intake up to 3 to 6 milligrams per day. Some healthful diets contain 9 to 13 mg of boron per day, which is still below the safe upper level of 20 mg/day. Charlene Rainey

Your article on boron as a micronutrient was very interesting, but I was confused by the last paragraph. It says we eat too few nuts but also recommends peanuts, which are legumes, not nuts. H.R. Maltrud

Both tree nuts and peanuts tend to be rich sources of boron.–J. Raloff
