The Claim

Higher consumption of ultra-processed foods, accounting for 8.5% of daily energy intake in Iranian adults, is associated with significantly lower intake of carbohydrates, protein, fiber, whole grains, fruits, and meat, and higher intake of total fat, saturated fat, trans fat, and cholesterol, indicating a less nutritious dietary pattern.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Iranian adults who consume more ultra-processed foods have diets with less carbohydrates, protein, fiber, whole grains, fruits, and meat, and more total fat, saturated fat, trans fat, and cholesterol.

See the scientific wording

Higher consumption of ultra-processed foods, accounting for 8.5% of daily energy intake in Iranian adults, is associated with significantly lower intake of carbohydrates, protein, fiber, whole grains, fruits, and meat, and higher intake of total fat, saturated fat, trans fat, and cholesterol, indicating a less nutritious dietary pattern.

Why this might work

When people eat more ultra-processed foods, they replace whole foods like fruits, whole grains, meat, and vegetables with products high in added fats and sugars. This directly lowers intake of carbohydrates from whole sources, protein, fiber, and essential micronutrients, while increasing total fat, saturated fat, trans fat, and cholesterol in the diet.

  1. Study: Association between ultra-processed foods consumption and micronutrient intake and diet quality in Iranian adults: a multicentric study

    In Iran, people who ate more ultra-processed foods also ate fewer healthy things like fruits, whole grains, and meat, and more unhealthy fats — meaning their overall diet was less nutritious.
