Food Perceptions in Adults with and without ADHD

INTRODUCTION

Adults with attention-deficit/hyperactivity disorder (ADHD) have unhealthy eating habits, associated with overweight/obesity. We explored whether they present with different food-related benefit/risk perceptions, compared to those without ADHD.

METHODS

One hundred five university students with (n = 36) and without (n = 69) ADHD, aged 22-30, participated in the study. They rated the level of frequency and likelihood of food consumption, as well as the perceived attractiveness, convenience, and risk of 32 healthy and unhealthy food items.

RESULTS

The findings revealed significantly lower healthy/unhealthy food frequency consumption ratios for the ADHD group compared with the non-ADHD one but no differences in the ratios of estimated likelihood of food consumption and perceptions (attractiveness, convenience, and risk).

CONCLUSION

The results of this study demonstrated a discrepancy between the eating behavior (more unhealthy eating patterns in adults with ADHD compared with controls) and their food-related perceptions (same perceptions regarding the benefit and risk of foods in both groups).

The major European dietary patterns and metabolic syndrome

Metabolic syndrome (MetS) is a cluster of risk factors that significantly increases the risk of cardiovascular disease. The lack of universally accepted diagnosis criteria makes it difficult to know the real prevalence of MetS in both adult and pediatric population. Lifestyle, especially nutritional habits and physical activity, have been suggested to be independent risk factors for the development of MetS. Recent studies highlight the need to prioritize overall dietary patterns, rather than isolated nutrients, to better appraise the associations between nutritional habits and MetS. In this review we summarize recently published intervention trials and systematic reviews that evaluated the association between overall dietary patterns and the risk of MetS. Westernized dietary patterns, characterized by a high consumption of meat or meat products, snacks, baked desserts and sugar-sweetened beverages, which provide high amounts of saturated fatty acids and simple carbohydrates as added sugars, have been associated with higher risk of MetS. In contrast, more traditional dietary patterns, including the Mediterranean dietary pattern (MDP), characterized by a high consumption of vegetables, fruits, whole cereals and fish are associated with a reduced risk of MetS. The main characteristics of the MDP include a high consumption of nuts and olive oil, resulting in a relatively fat-rich pattern that provides high amounts of mono- and polyunsaturated fatty acids, bioactive polyphenols and dietary fiber. Strong evidence is accumulating to support that a closer conformity with the MDP is inversely associated with the incidence of MetS, cardiovascular risk factors, diabetes and cardiovascular disease.
