Regularly consuming ‘ultra-processed’ foods increases risk of early death
Ultra-processed foods are mostly consumed in the form of snacks, desserts, or ready-to-eat or -heat meals.Updated: Feb 13, 2019 12:07 IST
While we all love nibbling away at our pizzas, chips or French fries, a new study, conducted in France, now finds that we face a 14% higher risk of early death with each 10% increase in the amount of ultra-processed food we eat.
The authors of the study wrote in the journal JAMA Internal medicine that ultra-processed foods are manufactured industrially from multiple ingredients that usually include additives used for technological and/or cosmetic purposes, reported CNN.
They added, “Ultra-processed foods are mostly consumed in the form of snacks, desserts, or ready-to-eat or -heat meals,” and their consumption “has largely increased during the past several decades.”
This trend may drive an increase of early deaths due to chronic illnesses, including cancer and cardiovascular disease, they say. According to the study, in the United alone 61% of an adult’s total diet comes from ultra-processed foods. In Canada, the figure is around 62% while in the UK, that proportion is 63%.
To understand the relationship between ultra-processed foods and the risk of an earlier-than-expected death, the researchers enlisted the help of 44,551 French adults for two years.
Their average age was 57, and nearly 73% of the participants were women. All provided 24-hour dietary records every six months in addition to completing questionnaires about their health, physical activities and sociodemographics.
The researchers calculated each participant’s overall dietary intake and consumption of ultra-processed food and found that it accounted for more that 14% of the weight of total food consumed and about 29% of total calories, they found.
Ultra-processed food consumption was associated with younger age, lower income, lower educational level, living alone, higher BMI and lower physical activity level.
Over the study period, 602 participants died. After adjusting for factors such as smoking, the researchers calculated an associated 14% higher risk of early death for each 10% increase in the proportion of ultra-processed foods consumed.
The authors speculate that the additives, the packaging (chemicals leech into the food during storage) and the processing itself, including high-temperature processing, may be the factors that negatively affect health.
