|Pancakes al cacao & your gut: Bad grains and good cacao?|
In today's installment of the SuppVersity Short News, I am going to take a closer look at a selection of recent studies that may shed at least some light at the previously mentioned questions.
- Cacao as a gut microbiome modulator - The first study we're going to look at deals with cacao. Cacao and its effect on the gut microbiome. In said study, 3-week-old Wistar and Brown Norway
rats were fed, for 4 weeks, either a standard diet or the following three isoenergetic diets containing increasing proportions of cocoa
flavonoids from different sources: one with 0·2 % polyphenols (from conventional defatted cocoa), and two others with 0·4 and 0·8 %
polyphenols (from non-fermented cocoa, very rich in polyphenols).
Only the regular theobromine containing cacao did also reduce the weight gain in the three-week study (Massot-Cladera. 2014).
As the body weight data in Figure 1 shows, the theobromine containing conventional cacao was also the only one that was able to reduce the diet induced weight gain in the rats. This could, but does not necessarily have to be related to the higher levels of Bacteroides, Bifidobacterium and Lactobacillus bacteria in the gut of the rodents that received the "cheap" conventional cacao.
- Acidic water triggers type I diabetes - probably by modulating the gut microbiome - No, I am not trying to advertise bicarbonate, here. I am just reporting the results of a recent study from the Medical University of South Carolina which found that a stain of mice that's particularly susceptible to type I diabetes developed insulitis and hyperglycemia rapidly, only when the mice were maintained on acidic pH water (AW).

As you as a SuppVersity reader know previous studies in humans have already shown that a "High Dietary Acid Load Doubles Risk of Type II Diabetes in Lean Individuals!" (read more) - Who knows, this could also be related to the effect on the gut microbiome!?
- Gluten and whole grains as modulators of the gut microbome - In two recent randomized cross-over trials, researchers from the University of Copenhagen determined the impact of dietary gluten or whole grains on the gut microbiome and host metabolic health.
What the researchers found was what the recent backlash against gluten and "healthy" whole grains on the internet would suggest the already overweight "[p]articipants had slightly elevated fasting glucose levels and increased waist circumference" (Ibrügger. 2014).
