文摘

Mineral nutrient composition of vegetables, fruits and grains is not declining. Allegations of decline due to agricultural soil mineral depletion are unfounded. Some high-yield varieties show a dilution effect of lower mineral concentrations. Changes are within natural variation ranges and are not nutritionally significant. Eating the recommended daily servings provides adequate nutrition.
