Abstract

Objective: This study assessed diet diversity and consumption of ultra-processed foods and explored its impact on macronutrient intake and risk of micronutrient inadequacy.

Design: Cross-sectional, non-probability snowball sampling.

Setting: Nutrient intake was assessed using 24-h dietary recall method and diet diversity through FAO-diet diversity score (DDS). Mann-Whitney test was used to assess differences in risk of inadequacy across gender. Spearman's rank correlation assessed associations between energy contributed by ultra-processed food and risk of nutrient inadequacy.

Participants: A total of 589 adults (20-40 years) belonging to upper-middle and high-income groups.

Results: The average individual DDS was 4·4 ± 0·6. Most of the participants (>80 %) had intakes less than national recommendations of pulses/eggs/flesh foods, milk/milk products, fruits, vegetables and nuts. Ultra-processed foods contributed to 17 % of total energy intake, 12 % of protein, 17 % of carbohydrate, 29 % of added sugar, 20 % of total fat and 33 % of Na intake. The average risk of nutrient inadequacies for Zn (98 % . 75 %), folate (67 % . 22 %) and niacin (83 % . 44 %) was higher among males than females ( < 0·001). The average risk of nutrient inadequacies for Fe (58 % . 7 %), vitamin B (95 % . 90 %) and vitamin A (68 % . 44 %) was higher among females than males ( < 0·001). There was a positive correlation between energy contributed by ultra-processed food and risk of niacin ( = 0·136, = 0·001) and folate ( = 0·089, = 0·049) inadequacy.

Conclusion: Reformulating ultra-processed food to reduce fat, sugar and salt and increase micronutrients and behaviour change communication strategies that promote dietary diversity will improve micronutrient adequacy and diet quality.
