Fiber is one of the nutrients that many people fall short on.
According to experts speaking to Real Simple, the majority of Americans do not meet the recommended intake levels.
Fiber does more than support digestion. Research published in BMC Public Health, Stroke, and Hypertension also suggests that a high fiber intake may be associated with a lower risk of conditions such as heart disease, high blood pressure, and type 2 diabetes.
Good sources of fiber include fruits, vegetables, whole grains, beans, nuts, and seeds.

Important minerals
Magnesium is another common deficiency. The mineral plays an important role in the body and helps support functions including muscle health and metabolism.
Iron is another nutrient that many people do not get enough of. A deficiency can lead to symptoms such as fatigue, weakness, and dizziness.
Sources of iron include meat, fish, beans, lentils, and leafy green vegetables.

Vitamin D is difficult to obtain in sufficient amounts through diet alone because the body primarily produces the vitamin through exposure to sunlight.
At the same time, vitamin D is important for bone health, the immune system, and the nervous system.
For this reason, several nutrition experts recommend that people who suspect they may be deficient have their vitamin D levels checked by a doctor.
