Most People Aren’t Getting Enough of These 7 Nutrients – Are You?

A variety of foods rich in essential nutrients, including fruits, vegetables, nuts, and whole grains, arranged on a wooden table.

When people think about nutrition, most tend to focus on the big stuff: calories, proteins, carbs, and fats. Essential vitamins and minerals our bodies need to function properly, also known as micronutrients, are often ignored. This neglect has consequences, however, and a recent study found that more than 5 billion people worldwide aren’t getting enough key micronutrients, putting them at risk for serious health problems.

What Nutrients Are Missing?

There are many different kinds of these important micronutrients, and they play crucial roles in everything from brain function to immune health. Here are some of the study’s findings on the more prominent ones:

68% of people worldwide are not getting enough iodine, which is essential for thyroid health.
66% fall short on calcium, a key mineral for strong bones and muscles.
67% don’t get enough vitamin E, which supports immune function and skin health.
Over 4 billion people don’t consume enough iron, riboflavin, folate, or vitamin C, all of which are vital for energy, blood health, and immune support.

Why Are So Many People Deficient?

Micronutrient deficiency isn’t just a problem in developing nations, even in countries like the United States where food is abundant, many people still don’t get the nutrients they need. One reason is that some lower income communities in the US live in “food deserts”. A "food desert", as defined by the United States Department of Agriculture (USDA), is a place with low levels of access to stores selling healthy and affordable foods.

Another big reason is the rise of ultra-processed foods, which have lots of calories but not enough important vitamins and minerals. Having easier access to these less nutritious foods makes it harder to get enough magnesium, zinc, and other key minerals.

How Can You Get More Micronutrients?

While supplements can help, the best way to improve micronutrient intake is through a well-rounded diet. Here are some foods you can add to your shopping list to boost key nutrients:
