In einer Studie an jungen Erwachsenen mit leichter bis mittelschwerer Akne fanden Forscher heraus, dass der tägliche Verzehr von etwa 60 Gramm Mandeln über 20 Wochen die Anzahl der Akneflecken deutlich reduzierte und die Vielfalt gesunder Bakterien auf der Haut verbesserte

To save you the trouble:
>*This research study was supported by the Almond Board of California, USA (SH-22-Udipi-NR-01).*
Lest we leap to any conclusions, though, a mechanism *is* suggested:
>Mechanistically, these outcomes can be attributed to almonds’ dietary fiber, unsaturated fat, and polyphenol content, which have been reported to increase butyrate-producing genera, such as *Roseburia* and *Lachnospira*, in the gut [51,52]. A recent study showed that both whole almonds and almond skins can exert prebiotic effects, significantly increasing *Bifidobacterium* and *Lactobacillus* [53]. Although these studies investigated the gut microbiome rather than skin, they provide biological plausibility that almond consumption enriches beneficial microbial taxa and increases microbial diversity through the bidirectional gut–skin axis. Alterations in gut microbiota, such as changes in diversity, short-chain fatty acid production, or systemic inflammatory mediators, can influence skin barrier integrity, immune responses, and sebum regulation, thereby affecting overall skin health and acne outcomes.
Interesting because almonds and other nuts always cause me to break out
How feasible is 60g of almonds per day? Sounds like a lot. Also, could the control group acne be influenced by the cereals?
“A defined amount of whole, unsalted almonds with skin (60 g), calculated to provide approximately 20% of the total daily energy intake (estimated as 1800–2000 Kcal/day, as per previous studies [31,32,33] conducted in this age group in urban India), was provided to the experimental group in two divided doses at midmorning and evening/midafternoon under supervision. The control group received cereal-pulse-based snack varieties, developed and standardized to be isocaloric to 60 g of almonds or approximately 350–360 Kcal. Given that fiber, fatty acid composition, and micronutrients, such as zinc or vitamin E, are integral components of the almond food matrix and represent potential mechanistic pathways through which almonds may exert their metabolic effects on skin and overall health, the nutritional profiles of control snacks were not matched to those of almonds.”
When I eat almonds, my acne gets worse
Thats.. a lot of almonds per day.
60 grams a day what am I a billionaire ?
Is it still true or was it proved false, that it takes 1 gallon of water to grow a single almond?
The glaring issue with this study is that basically none of these changes were actually statistically significant versus the control group.
Most of the results they trumpet are the almond group’s change from baseline. But the control group ALSO improved from baseline. The net effect is no major differences between the groups.
They hide most of this in table 4, in which the only between-group p value that is <0.05 is for acne QOL, and that’s a small difference that may well exist because of a ‚floor effect‘ (and, I’ve not checked if these p values are actually correct).
Focusing study results on these ‚change from baseline‘ results is one of my most despised forms of research manipulation – it effectively says that the control arm is irrelevant, which means those people who signed up for this study and agreed to be randomly assigned did so needlessly.
