A new NutriNet-Sante analysis from the Touvier and Srour group looks at food additive glutamate and cardiovascular risk. The digest recorded its existence and provenance; no effect sizes were extracted.
American Journal of Clinical · Hasenbohler et al. · 8 August 2026 · PMID 42570865
Soy lecithin and DATEM produced dose dependent gut barrier disruption and cytotoxicity at daily exposure doses in gut on a chip models, human colon organoids and mice, with IgE effects in mice and human cells. Not a human study.
Allergy · Yazici et al. · 8 August 2026 · PMID 42568319
A comprehensive review asks whether carrageenan is a food additive or a health concern, and a companion mechanism paper reports Bacteroides desulfating carrageenan and feeding hydrogen sulfide production. Reviews and mechanisms, not new human evidence.

In an eight week randomized placebo controlled trial in older adults, Pediococcus acidilactici PA53 was reported to improve stool consistency by 28% and reduce GI symptoms by 9.5%, with shakier headline gains in happiness and sleep. Every figure currently rests on trade reporting.
The Journal of Nutrition · Wang et al. · 4 August 2026
A systematic review of 91 sodium bicarbonate supplementation studies found GI symptoms rising dose dependently from 0.2 to 0.5 g/kg, and identified four promising mitigation strategies, none of which has been compared head to head.
European Journal of Sport · Winter et al. · undefined August 2026 · PMID 42499192
Cornell researchers fed resistant starch to more than 50 people and sequenced their microbiomes at strain level. Different strains of the same species, Bifidobacterium adolescentis, responded to the identical fiber in opposite directions.

A label audit of 108 US prebiotic sodas launched 2021 to 2025 found an average of 35 kcal, 5 g sugar and 5 g fiber per 12 oz can, fiber ranging from 2 to 9 g, and non nutritive sweeteners in about two thirds of products.
NUTRITION 2026, American Society · Carlos et al. · 25 July 2026
A Current Opinion in Sports Medicine argues that symptom severity, not habit, should decide whether an athlete restricts FODMAPs. Athletes with mild or occasional symptoms are likely better served by a more liberal FODMAP intake that supports gut integrity.
Sports Medicine · Scrivin et al. · 24 July 2026 · PMID 42496856
A human comparison of resistant starch versus polydextrose examined plasma and faecal bile acid profiles with microbiota associations; the abstract could not be retrieved before PubMed access closed, so no results are summarized.
European Journal of Nutrition · Fan et al. · 23 July 2026 · PMID 42489745
A narrative review by a prominent author group surveys gut microbiome strategies for athlete recovery, while conceding that the butyrate and propionate anti inflammatory evidence is largely preclinical.
Nutrients 18(14):2403 · Carlone et al. · 22 July 2026 · PMID 42514472
An in vitro screen found around 75% of 39 sweeteners altered the growth of at least one of 25 gut bacterial species. A separate narrative review concluded the evidence supports neither a uniformly harmful nor a uniformly safe verdict on artificial sweeteners.

In 24 elite male combat athletes cutting weight before competition, a seven strain probiotic kept GI symptoms and gut barrier markers roughly stable over four weeks while the placebo group deteriorated sharply.
Frontiers in Nutrition · Wang et al. · 15 July 2026
In a six week randomized trial in adults with knee osteoarthritis, 20 g/day inulin reduced pain by roughly as much as a supported exercise programme, and the dropout gap was striking: 3.6% left the inulin arm against 21% for exercise.
