WASHINGTON — Diets such as paleo and Whole30 are gaining traction among Americans. The International Food Information Council Foundation’s 13th annual Food and Health Survey found 36% of Americans said they followed a specific eating pattern or diet within the past year.

The top pattern cited was intermittent fasting at 10%. Diets restricting carbohydrate intake were represented as well with 7% following a paleo diet, 5% following a low-carbohydrate diet, 5% following the Whole30 diet, 4% following a high-protein diet and 3% following a ketogenic/high-fat diet.

The paleo diet focuses on items that cavemen ate, including meat, fish, nuts, leafy greens, vegetables and seeds. The Whole30 diet is similar in that it promotes the consumption of meat, poultry, fish, vegetables, fruits and nuts. People on the Whole30 diet go 30 days without consuming sugar or natural or artificial sweeteners, alcohol, grains, beans or legumes, soy, dairy, and processed additives.

Many Americans are shunning sugar and carbohydrates, according to the survey, while others are seeking organic and natural options. Sugar was the most cited source of weight gain at 33% and was followed by carbohydrates at 25%, up from 20% in the 2017 survey. Seventy-seven per cent of respondents said they were trying to limit or avoid sugars in their diets.

People do perceive certain elements of grain-based foods as healthy. More than 80% of respondents listed both fiber and whole grains as healthy, trailing only vitamin D. More than 70% said protein from plant sources, which compared to just under 40% for animal protein.

People who said they bought products labeled as organic rose to 29%, up from 25% in 2017. Those who said they bought foods and beverages labeled as natural rose to 37% from 31%.

When asked to choose between a version of a product that includes artificial ingredients and a newer version of the same product that does not include artificial ingredients, 69% chose the product with no artificial ingredients. When asked how much more they would be willing to pay for a product with no artificial ingredients compared to one with artificial ingredients that costs $1, 62% said up to 10% more, 42% said up to 50% more, and 22% said they would pay double the price.

When asked to identify the healthier of two products with the same Nutrition Facts Label, 40% perceived one labeled as “Non-G.M.O.” as healthier versus 15% for one with genetically engineered ingredients. Thirty-three per cent said they believed a product with a shorter ingredient list was healthier than one with more ingredients. Fifteen per cent said the product with more ingredients was healthier.

The survey also found 20% ranked cardiovascular health as their top desired benefit. Other answers were weight loss and weight management at 18% and energy at 13%. Only 38% were able to name a food they would seek to help with their top health concern. Most frequently identified were protein at 10%, vegetables at 7%, vitamins and minerals at 5%, and fruit at 4%.

“This dietary disconnect – the inability to connect specific foods and nutrients to desired health outcomes – illustrates the need for stronger, clearer, nutrition education based on the best available evidence,” said Joseph Clayton, chief executive officer of the IFIC Foundation.
