Processed Foods and Health

A number of headlines have reported the impact of processed and ultra-processed foods on obesity, health and premature death. So we have explored what these terms mean and what the evidence really shows.

What are Processed Foods?

There are a number of different definitions for processed and ultra-processed foods which tend to separate foods by the number of ingredients they contain and the level of processing undergone. The most common definition for processed foods is the NOVA classifications:

  • Processed foods are foods containing 2-3 ingredients that are minimally processed e.g. canned vegetables, cheese, freshly made bread.
  • Ultra-processed foods are foods containing 5 or more ingredients with ‘industrial formulations’ with added ingredients to enhance flavour, texture of life e.g. cakes, cured meat, ice creams, added sugar fizzy drinks.

These rather broad and varying definitions of processed foods means it’s difficult to gather evidence to understand their impact on health.

These classifications also don’t take into account the calorie or nutrient content of the foods which research has shown has a direct influence on our health and weight.
