Resistant starch, β-glucan, and inulin

This 2021 paper reported results of two related human clinical trials: “Lean and prediabetic overweight/obese men were included in two randomized crossover studies. In one study, participants received supplements of either long-chain inulin+resistant starch (INU+RS), INU or maltodextrin (placebo, PLA) the day prior to a clinical investigation day. The second trial studied beta glucan+RS (BG+RS) … Continue reading Resistant starch, β-glucan, and inulin

Eat oats for β-glucan and resistant starch

This 2021 review highlighted effects of processing oat products: “Starch contents in oats ranges from 51% to 65%. Resistant starch (RS) accounts for 29.31% of starch content in raw granular form of oat starch. RS in raw oat starch is RS2 starch, where its slow digestion is mainly due to the compact nature of starch … Continue reading Eat oats for β-glucan and resistant starch

Resistant starch therapy

This 2021 review subject was interactions among resistant starches and gut microbiota: “Starch that reaches the large intestine without being fully digested is termed resistant starch (RS). Starch digestibility should be considered as a kinetic property (slower to faster) affected by host-specific factors, rather than as a binary trait (resistant or nonresistant). RS is degraded … Continue reading Resistant starch therapy

Green light for BBQ?

Two 2022 papers from a clinical trial investigating dietary AGEs’ effects in middle-age people: “A 4-week diet low or high in AGEs has no effect on insulin sensitivity, secretion, or clearance; vascular function; or overall inflammation in abdominally obese but healthy individuals. These findings require validation in large prospective cohort studies and in populations with … Continue reading Green light for BBQ?

Gut microbiota knowledge through 2021

I’ll curate this 2022 review of what’s known and unknown about our trillions of gut microbiota through its topic headings: “Most microbial taxa and species of the human microbiome are still unknown. Without revealing the identity of these microbes as a first step, we cannot appreciate their role in human health and diseases. A. Understanding … Continue reading Gut microbiota knowledge through 2021

Gut microbiota responses to inulin

This 2021 rodent study investigated: “We studied long-term dynamics of gut microbiome and short-chain fatty acids (SCFAs) in isogenic mice with distinct microbiota baselines fed with fermentable fiber inulin compared to non-fermentable fiber cellulose. We found that inulin produced generally rapid response followed by gradual stabilization to new equilibria, and those dynamics were baseline-dependent. Levels … Continue reading Gut microbiota responses to inulin

Eat oat avenanthramides for your gut microbiota

This 2021 paper covered a 2016 human clinical trial, and several in vitro and rodent follow-up studies: “Oat has been widely accepted as a key food for human health. It is becoming increasingly evident that individual differences in metabolism determine how different individuals benefit from diet. Both host genetics and gut microbiota play important roles … Continue reading Eat oat avenanthramides for your gut microbiota

Part 2 of Make your gut microbiota happy

Continuing from Part 1, 7/15/2021 test results received 7/27 showed I was putatively below average in four gut bacteria. The most relatively deficient (percentage-wise) were populations in genus Bifidobacterium: Looking through Thryve’s recommended foods, eating all but one (green lentils) of twenty legumes increased genus Bifidobacterium. Here’s a sample: I already had dried garbanzo and … Continue reading Part 2 of Make your gut microbiota happy

Eat whole oats for your gut microbiota

Two papers on whole grains, with the first a 2021 review: “Whole grains are more complex than refined grains and are promoted as part of a healthy and sustainable diet, mainly because the contribution of indigestible carbohydrates, and their co-passenger nutrients, is significantly higher. Changing composition and availability of grain carbohydrates and phytochemicals during processing … Continue reading Eat whole oats for your gut microbiota

Dietary fibers and the aged microbiome

This 2021 rodent study investigated effects of four different types of dietary fiber on two different types of aged human microbiota: “Individual differences in gut microbiota may influence host metabolic responses to dietary fiber in humans. Dietary fibers are edible carbohydrates resistant to host digestive enzymes, and not broken down or absorbed in the small … Continue reading Dietary fibers and the aged microbiome

Effects of another broccoli sprout compound

This 2020 rodent study investigated effects of broccoli sprout hydrolysis compound indole-3-carbinol: “I3C metabolites act as ligands of the aryl hydrocarbon receptor (AhR), an important sensor for environmental polyaromatic chemicals. We investigated how dietary AhR ligand supplementation influences AhR target gene expression and intestinal microbiota composition. Environmental signals, such as dietary, microbial, or xenobiotic factors, … Continue reading Effects of another broccoli sprout compound

Pigs and glucosinolates

This 2020 porcine study subject was improving healthy aspects of canola-oil-processing by-products: “We hypothesized that inclusion of high-amylose cornstarch (HA-starch) in canola co-products-based diets for pigs can reduce hindgut pH, leading to increased degradation of glucosinolates present in hindgut of pigs into non-goitrogenic products. Most dietary myrosinases [enzymes] are inactivated by heat during cooking, pressing … Continue reading Pigs and glucosinolates

Oat digestibility

A reader questioned one part of Oat species comparisons of the good stuff regarding Avena nuda hull digestibility. This 2019 study partially investigated that aspect: “We investigated effects of proteins, lipids, and β-glucan in naked oat flour on in vitro digestibility of starch. Content of rapidly digested starch increased, and content of resistant starch decreased … Continue reading Oat digestibility

Time-restricted prebiotics

My 700th curation is a 2021 rodent study that investigated time-restricted prebiotic intake combined with an unrestricted bad diet: “Restricted prebiotic feeding during active phase induced weight-independent alleviation of liver steatosis and reduced serum cholesterol in high-fat diet (HFD) fed mice more significantly than unrestricted feeding. The prebiotic was a mixture of resistant starch [86%], … Continue reading Time-restricted prebiotics

Eat oats to prevent diabetes

This 2020 rodent study investigated Type 2 diabetics eating oats along with a bad diet: “Type 2 diabetes (T2D) is a metabolic disease which is characterized by a state of chronic low-grade inflammation with abnormal expression and production of multiple inflammatory mediators. Insulin resistance (IR), a condition where higher-than-normal concentration of insulin is needed to … Continue reading Eat oats to prevent diabetes
