The effects of processed foods on our health are overwhelmingly negative. Overfed and undernourished, many America diets share some of the most common nutrient deficiencies.

It’s a paradox of modern culture: Though more than a third of us are classified as overweight or obese, and though more than 3,700 calories of food are available daily for every person in the United States, many of us still don’t get enough of some essential nutrients, including potassium, calcium and vitamin D. This paradox, in which we are overfed and undernourished, is sometimes called nutrient deficiency.

In its latest update of the Dietary Guidelines for Americans (2010), the United States Department of Agriculture (USDA) announced that our average intake of some of these “nutrients of concern” is so low as to be a widespread public health issue. How is it that we eat so much, yet lack key nutrients?

The answer to that question is complex, encompassing everything from food distribution to the failings of industrial agriculture. One thing is clear: We now eat too much of the wrong kinds of food. We consume too many sugary soft drinks and fat-laden desserts and not enough nutrient-dense fruits and vegetables, beans, and whole grains. As our waistlines expand, diet-related diseases and their associated costs grow along with them. Science has linked nutrient deficiencies to a variety of diseases and unhealthful conditions. For example, a recent study in Australia that compared five types of diets found a direct link between women who preferred nutrient-poor foods and increased osteoporosis and fractures, which indicates calcium deficiencies. Few consume the recommended daily amount of potassium — a nutrient that helps lower blood pressure — and one in three of us suffers from hypertension.

Increasing evidence shows that our consumption of fats, sugars and fluffy white foods contributes to the incidence of degenerative, age-related diseases such as cancer, cognitive decline, cardiovascular disease and stroke. Biochemist Bruce Ames — who has won numerous prestigious awards, including the National Medal of Science — argues that widespread vitamin and mineral deficiencies in modern diets result in chromosomal damage that leads to cancer and accelerated aging.
