Nutrients Most People Do Not Get Enough Of (2026 Data)

The nutrients most adults fall short on, with the share of people below their needs, daily targets, and easy food fixes.

Medically reviewed by Dr. Emily Torres, Registered Dietitian Nutritionist (RDN)

Approximately 95% of adults do not consume enough fiber and vitamin D, while around 98% fall short on potassium. This data highlights the importance of increasing intake of fruits, vegetables, beans, nuts, and whole grains to meet nutritional needs.

This article examines the nutrients that many adults fail to consume adequately, based on national intake surveys. The findings align with the US Dietary Guidelines, which identify key nutrients of concern.

The Data

The following table summarizes the intake levels of nutrients that are commonly underconsumed by adults.

Nutrient % of Adults Below Needs Daily Target Easy Food Fixes
Potassium ~98% 2,600-3,400 mg Potato, banana, beans, spinach
Fiber ~95% 25-38 g Beans, oats, berries, vegetables
Vitamin D ~95% 600-800 IU Salmon, fortified milk, sunlight
Choline ~90% 425-550 mg Eggs, meat, soybeans
Vitamin E ~88% 15 mg Almonds, sunflower seeds, spinach
Magnesium ~48% 310-420 mg Pumpkin seeds, nuts, greens, beans
Vitamin C ~46% 75-90 mg Citrus, bell peppers, strawberries
Vitamin A ~45% 700-900 mcg Sweet potato, carrots, spinach
Calcium ~40% 1,000-1,200 mg Dairy, fortified plant milk, tofu
Iron (women) ~13% 18 mg Red meat, lentils, spinach, fortified cereal

The "big four" the Dietary Guidelines flag: fiber, vitamin D, calcium, potassium

The US Dietary Guidelines highlight four key nutrients of concern: fiber, vitamin D, calcium, and potassium. About 95% of adults do not get enough fiber and vitamin D, while around 98% are deficient in potassium. Calcium intake is also lacking, contributing to potential health issues such as osteoporosis.

The gaps that hit vegetarians and vegans hardest

Vegetarians and vegans may experience significant nutrient gaps, particularly in vitamin B12, iron, and omega-3 fatty acids. These groups often consume fewer animal products, which are primary sources of these nutrients. This can lead to deficiencies if not properly managed through diet.

How to close the gaps with food, not pills

To address these nutrient gaps, individuals should focus on incorporating a variety of whole foods into their diets. Foods rich in fiber, such as fruits, vegetables, legumes, and whole grains, can help meet daily requirements. Additionally, fortified foods and natural sources of vitamin D, calcium, and potassium should be prioritized.
