Three additive types tracked about 45% more depression; five others tracked nothing

Ultra-processed food is usually condemned or defended as one block. Following 171,818 UK adults for a decade, only three of ten additive categories tracked depression, and they did so in proportion to how much was eaten.

The sweetener in your sugar-free label is also made by your body, and its level tracks insulin resistance

Erythritol is sold as a sweetener and quietly produced inside us from glucose. In 802 adults on a weight-loss trial, the people whose blood erythritol fell furthest were the ones whose insulin resistance improved most, two years on.

Four ultra-processed ingredients tracked high blood pressure

A European Heart Journal study followed 101,560 UK Biobank participants for a decade, sorting their food by what their ingredient lists held. Colorings, sweeteners, flavorings and sugars tracked new high blood pressure. Five did not.

Heavy drinking and obesity both raised diabetes risk, separately

A Diabetologia study followed 7,817 Korean adults for 16 years and found obesity and heavy drinking each raised diabetes risk, but combined less than adding them up would predict.

Artificial sweeteners linked to worse blood-sugar control
