Highlights
• UPF consumption was associated with depressive symptoms.

• Higher UPF consumption was associated with lower volumes in mesocorticolimbic brain regions.

• White blood cell count levels mediate the association between UPF consumption and depressive symptoms.

• The presence of obesity interacted with the associations found with UPF consumption.

Processed foods are the 'tobacco' of today.

Eating heavily processed foods—particularly artificial sweeteners and artificially sweetened drinks—could increase the risk of developing depression, according to research published Wednesday in JAMA Network Open, another major downside to the pervasive ingredients that dominate American diets and have already been linked to major problems like cancer, diabetes and obesity.

Researchers from the United States, Brazil, and Spain, including scientists with the Fralin Biomedical Research Institute at VTC, published an analysis in a special edition of the British Medical Journal with a timely and controversial recommendation: It’s time for an international shift in the way we think about ultra-processed food.

“There is converging and consistent support for the validity and clinical relevance of food addiction,” said Ashley Gearhardt, the article’s corresponding author and a psychology professor at the University of Michigan. “By acknowledging that certain types of processed foods have the properties of addictive substances, we may be able to help improve global health.”

While people can give up smoking, drinking, or gambling, they can’t stop eating, said co-author Alexandra DiFeliceantonio, assistant professor at the Fralin Biomedical Research Institute. The challenge, and the open and controversial question, is defining which foods have the most potential for addiction and why.

Ultraprosessoituihin ruokiin pitäisi saada ”riippuvuutta aiheuttavan elintarvikkeen merkintä”, tutkijat sanovat

TEKSTI VEIKKA NIEMI

Uusi kansainvälinen koontitutkimus on saanut selville, että jopa 14 prosenttia aikuisista ja 12 prosenttia lapsista voi kärsiä ultraprosessoidun ruoan riippuvuudesta.

Tutkimus tarkasteli yhteensä 281 aiheesta 36 eri maassa tehtyä tutkimusta. Se on julkaistu British Medical Journal -tiedejulkaisussa. Havaitut lukemat kääntyvät yhteen aikuiseen seitsemää aikuista kohden ja yhteen lapseen kahdeksaa lasta kohden. Esimerkiksi jäätelö, valmisateriat ja virvoitusjuomat ovat terveyteen negatiivisesti vaikuttavia ultraprosessoituja elintarvikkeita (ultra-processed foods, UPF).


UPF-ELINTARVIKKEIDEN kulutus on etenkin länsimaissa suurta. Yhdysvalloissa ja Isossa-Britanniassa ne muodostavat jo yli puolet ihmisen keskivertoruokavaliosta. Uusi tutkimus on havainnut nyt, että joidenkin UPF-elintarvikkeiden kulutukseen liittyvien toimintatapojen taustalla voi olla päihderiippuvuuden kaltainen sairaus.

Oireita voivat olla hallitsemattomat himot, vierotusoireet ja oman kontrollin pettäminen siinä, kuinka paljon UPF-elintarvikkeita kuluttaa. Myös se, että jatkaa UPF-elintarvikkeiden kuluttamista entiseen malliin terveydentilan selkeästä heikkenemisestä huolimatta, voisi viitata UPF-riippuvuustilaan.

Incomplete understanding of the multiple mechanisms underlying the link between ultra-processed foods and cardiometabolic health should not be an excuse for inaction argue Mathilde Touvier and colleagues

The effect of diet on health has historically been considered from a nutrient based perspective—for example, excess total fat, saturated fat, dietary cholesterol, calories, sugar, or salt and lack of dietary fibre, vitamins, and minerals.1 More recently, this approach has been complemented by extensive evidence supporting health effects of dietary patterns (eg, the Mediterranean diet), characterised by various dietary scores such as the Alternative Healthy Eating Index (AHEI), or DASH (Dietary Approaches to Stop Hypertension) diet.2 However, the degree of processing and formulation of foods was not taken into account. For instance, all vegetable soups were considered similar, regardless of whether they were homemade, industrial canned, or industrial dehydrated and contained food additives and flavours.

The potential health effect of food processing and food formulation, beyond their food ingredients, nutrient composition, and energy content, is now being widely researched. An important milestone was the 2009 publication of the NOVA classification,3 which categorises foods according to the type, intensity, and purpose of food processing (box 1). The ultra-processed group includes all foods and drinks made using intense physical or chemical processes or containing cosmetic food additives and other industrial ingredients (eg, artificial flavours, hydrogenated oils, glucose/fructose corn syrup).
