The five most glaring deficiencies are:
* potassium;
* vitamin E;
* magnesium;
* vitamin A;
* fiber.
For example, 99 percent of women and 90 percent of men fail to get adequate potassium, a shortfall that may contribute to alarming rates of high blood pressure. Half of Americans fall short on fiber - a key macronutrient that helps control cholesterol.
The accompanying chart shows where we fall short, why we need these nutrients and where to get them. Other neglected nutrients include:
* Vitamin C: 40 percent of men and 38 percent of women 19 or older don't get enough. The good news is that it's easy to increase your intake with top sources like red/yellow bell peppers, kiwi, oranges and broccoli.
* Calcium: Half of women and 40 percent of men are deficient. Top plant sources of calcium include soybeans, kale and arugula.
* Zinc: One-third of people over 70 years old do not get enough zinc. Sources include oysters, beans, oats and green peas.
* Vitamin B-6: Almost one-third of adult women do not get enough. Good sources include potatoes, bananas, red bell peppers and broccoli.
* Phosphorus: Forty percent of young women (ages 9 to 18) do not get adequate phosphorus. Top sources include lentils, sardines, salmon and portobello mushrooms.
