Probiotic‐rich bean sprouts alleviate oxidative stress and inflammation induced by a diet with an increased fat‐to‐carbohydrate energy ratio
SummaryThe rat's model evaluated the function of sprouted beans enriched with probiotic Lactiplantibacillus plantarum 299v in alleviating dyslipidaemia, inflammation and disturbed redox homeostasis caused by a high‐lard diet. Sprouted beans improved the total antioxidant capacity of serum and liver, regardless of whether the feeds had a higher content of low‐molecular antioxidants or were additionally enriched with probiotics. The reduction of inflammation (lowered level of C‐reactive protein) and restoration of triglycerides and total cholesterol to the levels recorded in the control group (AIN‐93M) were especially observed in the group supplemented with the control adzuki bean. Introducing sprouted legumes (both the control and probiotic‐rich) improved microbiota activity affected by a high‐lard diet. The highest, desirable reduction of urease (by 80%) and tryptophanase (by 78%) activity was found in the groups fed with probiotic‐rich adzuki and mung bean sprouts respectively. Sprouted beans improve the metabolism of individuals subjected to a diet with an increased fat‐to‐carbohydrate energy ratio, especially concerning oxidative stress injury and microbiota activity.
Analysis of Phenolic Compounds in Buckwheat (Fagopyrum esculentum Moench) Sprouts Modified with Probiotic Yeast
Buckwheat sprouts are a source of various nutrients, e.g., antioxidant flavonoids, which have a positive effect on human health. This study analyzed the content of phenolic compounds and assessed their impact on the antioxidant and anti-inflammatory properties and dietary fiber in modified buckwheat sprouts. For this purpose, the buckwheat seeds were modified by adding Saccharomyces cerevisiae var. boulardii. The modified buckwheat sprouts showed a higher content of total phenol compounds (1526 µg/g d.w.) than the control sprouts (951 µg/g d.w.) and seeds (672 µg/g d.w.). As a consequence, a higher antioxidant activity and anti-inflammatory effect were noted. Probiotic-rich sprouts also had the highest content of total dietary fiber and its soluble fraction. A correlation between phenolic compounds and the antioxidant and anti-inflammatory effects, as well as dietary fiber, was shown. The interaction between dietary fiber and phenolic compounds affects the bioaccessibility, bioavailability, and bioactivity of phenolic compounds in food. The introduction of probiotic yeast into the sprouts had a positive effect on increasing their nutritional value, as well as their antioxidant and anti-inflammatory activity. As a consequence, the nutraceutical potential of the raw material changed, opening a new direction for the use of buckwheat sprouts, e.g., in industry.
