Patient Q&A Section

How many people get food preferences a year in the United States?

"The most frequent food preferences among US adults are vegetables for men and women and sweets plus fat for women. These preferences are prevalent when considering one's health and eating behaviors. However, many people don't have these preferences. For example, about two-thirds of Americans are vegetarians but about half do not prefer vegetables and another quarter don't like sweets and fat. Even more, about 30% do not prefer sweets and fat at all. These food preferences in the United States suggest that there is room for improvement in both the food choices of adults and people's eating behaviors." - Anonymous Online Contributor
