The government departments of Agriculture and Health and Human Services have jointly issued new dietary guidelines for those of us 2 years and older. Sodium should be restricted to 1500 mg in blacks, those greater than 51 y.o., and those with hypertension, diabetes, etc. and 2300 mg for the rest. Nutrient dense foods are recommended, such as whole grains, seafood (but not shark, swordfish and king mackerel due to high mercury content), eggs, beans, nuts and soy. The latter is controversial. Fewer solid fats make sense but I disagree with their recommendation of using low fat and fat-free foods because these are often highly processed. Foods with iron and folic acid for women, vitamin C, and vitamin B12 for those over 50 are recommended.
