Long-Term Study Shows Americans Have Significantly Reduced Consumption of Minerals

Examining trends in mineral intake and their sources among American adults from 1999 to 2020, this study analyzed data from over 48,000 participants. Assessing changes in the intake of key minerals, such as calcium, magnesium, iron, and sodium, as well as their sources in the diet, the goal was to inform policymakers about how mineral intake has shifted over time in response to changes in the economy, dietary guidelines, and other factors.

The results showed that intake of some minerals, like calcium, magnesium, phosphorus, and sodium, increased over time, while intake of others, such as iron, zinc, copper, and potassium, decreased. The percentage of people meeting the recommended intake for minerals like calcium, phosphorus, and sodium increased, but fewer people met the recommendations for iron, potassium, zinc, and copper.

Overall, the study found significant changes in both mineral intake and their sources, with certain mineral deficiencies and excesses still posing challenges for U.S. adults. While there were improvements, such as increased intake of certain minerals, issues like overconsumption of sodium and underconsumption of key nutrients like potassium, calcium, and magnesium remained persistent. The findings highlight the importance of ensuring adequate mineral intake from food and supplement sources.
