"Addressing Nutrient Deficiencies in American Diets"

The standard American diet is lacking in four critical nutrients - dietary fiber, calcium, potassium, and vitamin D - which are associated with chronic diseases like type 2 diabetes and cardiovascular disease. Women should aim for 25 grams of fiber, 1,000 milligrams of calcium, 2,600 milligrams of potassium, and 600 IU of vitamin D daily, while men should target 38 grams of fiber, 1,000 milligrams of calcium, 3,400 milligrams of potassium, and 600 IU of vitamin D. Foods like dark leafy greens, dried fruits, dairy products, and fatty fish can help fulfill these nutrient requirements.
