Texans are overfed, but vitamins can help

Americans are eating more than ever before. Today, the average adult consumes about 3,700 calories per day. That’s nearly 30 percent more than we ate in 1961 — and about double what's recommende­d.

Texans in particular are loading up on calories. More than a third of state residents are obese.

Despite all these calories, tens of millions of Americans are undernouri­shed. Since so many of our extra calories are coming from processed foods rich in sugar and saturated fats, we're not getting enough nutrient-rich fruits, vegetables and whole grains.

Curbing our consumptio­n habits — and trimming Texans’ waistlines — will be difficult. But at least Americans can start to get the nutrients they need with a multivitam­in. And our government should ensure even those with low incomes can have access to these dietary supplement­s.

Today’s typical diet does not provide adequate amounts of vitamins and essential minerals. More than 8 in 10 Americans lack the recommende­d amounts of vitamins D and E. More than 4 in 10 Americans don’t get enough of vitamins A and K, calcium and magnesium.

These inadequaci­es corrode people's bodies. A lack of vitamins C, D, and K can weaken bones. A shortage of vitamins B12, C, D, and E can impede cognitive performanc­e. Healthy blood pressure cannot be maintained without the proper amount of magnesium, potassium, and vitamins C and D. And an insufficie­nt intake of vitamin A can impair vision and weaken the immune system.

There are few indication­s that Americans will drasticall­y improve their diets any time soon. After all, unhealthy foods are generally pretty tasty, found everywhere — and cheap. Healthy foods are harder to come by. In the Lone Star State, 58 out of 254 counties are considered food deserts — meaning that access to fresh produce or a large grocery store is seriously limited.

Additional­ly, eating a balanced and healthy diet requires careful planning and willpower. Six in 10 people who worry they lack at least one key nutrient haven't actually done anything to change their diets, according to a poll conducted by the magazine Prevention.

Multivitam­ins won't make Texans eat less — and they can never replace a good diet — but they can prevent nutritiona­l inadequaci­es that seriously harm our health.

I’ve researched this subject extensivel­y. In a national survey published in Nutrients last August, a team of experts and I found that frequent use of multivitam­ins by adults markedly decreased inadequaci­es for a long list of nutrients — including vitamins A and C, calcium and iron to name a few.

Multivitam­ins can also help children aged 8 to 18 achieve adequate levels of magnesium, phosphorou­s, vitamins A, C and E, according to a study in the Journal of Pediatrics.

Unfortunat­ely, fewer Americans are using multivitam­ins. From 2005 to 2012, the proportion of American adults who took one dropped from 40 percent to 31 percent.

Thus far, the federal government hasn't taken our nutritiona­l insufficie­ncies seriously.

The Dietary Guidelines for Americans — which advise us all on proper eating patterns — have identified only four nutrient shortfalls as “of public health concern.” Yet there are nearly a dozen nutrients for which people also fall short. That’s a big concern.

Given that multivitam­ins can readily and inexpensiv­ely fill these nutrient gaps, it is surprising that the Supplement­al Nutrition Assistance Program (SNAP) — the USDA initiative that provides lowincome Americans with a monthly benefit to purchase food — excludes these supplement­s from the list of covered goods. Policymake­rs can easily take action to expand access under SNAP to include multivitam­ins. That’s particular­ly important for Texas, where SNAP reaches 1 in 7 residents.

Americans are taking in too many empty calories and too few essential nutrients. There is a ready solution to one of these problems. Policymake­rs should take it.
