“…Ruminants possess a better potential to degrade large quantities of starch, which has a different degree of resistance to degradation. Several factors determine the rate and extent of starch digestion in the rumen, such as crystallinity, a ratio of amylose/amylopectin, particle size, and cooking approach ( 1 , 2 ). Amylose and amylopectin are the main components of starch and can determine the nutritional and biochemical properties of starch ( 1 ).…”

Increasing the ratio of amylose in the diet can increase the quantity of starch that flows to the large intestine for microbial fermentation. This leads to the alteration of microbiota and metabolite of the hindgut, where the underlying mechanism is not clearly understood. The present study used a combination of 16S amplicon sequencing technology and metabolomics technique to reveal the effects of increasing ratios of amylose/amylopectin on cecal mucosa- and digesta-associated microbiota and their metabolites in young goats. Twenty-seven Xiangdong black female goats with average body weights (9.00 ± 1.12 kg) were used in this study. The goats were randomly allocated to one of the three diets containing starch with 0% amylose corn (T1), 50% high amylose corn (T2), and 100% high amylose corn (T3) for 35 days. Results showed that cecal valerate concentration was higher (P < 0.05) in the T2 group than those in the T1 and T3 groups. The levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were decreased (P < 0.05) in cecal tissue while IL-10 was increased (P < 0.05) in the T2 group when compared with T1 or T3 groups. At the phylum level, the proportion of mucosa-associated Spirochaetes was increased (P < 0.05), while Proteobacteria was deceased by feeding high amylose ratios (P < 0.05). The abundance of Verrucomicrobia was decreased (P < 0.05) in the T3 group compared with the T1 and T2 groups. The abundance of digesta-associated Firmicutes was increased (P < 0.05) while Verrucomicrobia and Tenericutes were deceased (P < 0.05) with the increment of amylose/amylopectin ratios. The LEfSe analysis showed that a diet with 50% high amylose enriched the abundance of beneficial bacteria such as Faecalibacterium and Lactobacillus in the digesta and Akkermansia in the mucosa compared with the T1 diet. The metabolomics results revealed that feeding a diet containing 50% high amylose decreased the concentration of fatty acyls-related metabolites, including dodecanedioic acid, heptadecanoic acid, and stearidonic acid ethyl ester compared with the T1 diet. The results suggested that a diet consisting of 50% high amylose could maintain a better cecal microbiota composition and host immune function.

“…Nonetheless, considering that there were generally no significant differences between groups in the phenotypic outcomes of interest, results from additional assays on these genes are not expected to cause a material difference in the conclusions. Second, the 10% kcal group consumed a diet with some sugar replaced by cornstarch and maltodextrin, which is rapidly absorbed in the small intestine ( 49 ). Although it has been shown that long-term intake of maltodextrin and cornstarch may have adverse health effects such as impaired insulin sensitivity and hyperlipidemia ( 50 ), the difference in % kcal of glucose from digestion of cornstarch and maltodextrin between 10 and 25% kcal sucrose diets in our study is considered small (e.g., 55 vs. 47.5% kcal glucose for 10% and 25% kcal sucrose diets, respectively, assuming 60% kcal from carbohydrates), that would only have minute influences if any on our study results, which overall also showed no significant differences between groups.…”

IntroductionControversies surround the issue if chronic consumption of a high-sugar diet is detrimental to health or not. This study investigates whether lifelong consumption of a higher sucrose diet will induce overeating, and obesity, and cause metabolic dysfunctions such as hyperglycemia and dyslipidaemia in C57BL/6N mice, compared to a lower sucrose diet.MethodsMale C57BL/6N mice at 3 weeks of age were randomized into consuming a diet with 25 or 10% kcal from sucrose for the rest of their lives. Body weight, food and water intake, fasting blood glucose, insulin, and lipid levels were measured at regular intervals. At the end of the study, organs and tissues were collected and gene expression was measured.ResultsThere was no discernible difference in the impact on food intake, body composition, glucose and lipid homeostasis, liver triglyceride content, life expectancy, as well as gene expression related to intermediary metabolism between mice fed a diet with 10 vs. 25% kcal as sucrose over their lifespan. We also showed that switching from a 25% kcal diet to a 10% kcal diet at different life stages, or vice versa, did not appear to affect these outcomes of interest.DiscussionThe results from our study suggest that lifelong consumption of a higher sugar diet generally did not induce overeating and obesity, disrupt carbohydrate metabolism and lipid homeostasis, and reduce life expectancy compared with a lower sugar diet. Our unorthodox findings disagreed with the popular belief that higher sugar consumption is detrimental to health, which should be confirmed in future studies.

“…[1] It is the primary energy source for the human body and is widely utilized in food production. Native corn starch (NCS) has been used in many food products even though it commonly presents very rapid digestibility [2] because it contains a large amount of rapidly digestible starch (RDS), which might promote some health problems such as type-2 diabetes obesity, and excess weight due to an abrupt rise in glycemic response. [3] Encapsulation of starch granules has been noticeable for slowing down starch hydrolysis because the starch becomes less accessible when surrounded by a food matrix, known as Type 1 resistant starch (RS1).…”

The study aims to investigate the influence of hydrocolloid matrices, including sodium alginate (SA) and guar gum (GG), on the digestive properties of native corn starch (NCS). The native starch is encapsulated with SA (1% w/v), SA (0.75% w/v) + GG (0.25% w/v), SA (0.50% w/v) + GG (0.50% w/v), SA (0.25% w/v) + GG (0.75% w/v), and GG (1% w/v) through a laboratory-scale spray drying process. The results reveal novel comparative and cooperative effects of encapsulant materials on starch hydrolysis. SA is found to be a superior encapsulant in terms of enhancing the slowly digestible starch (SDS) and resistant starch (RS) contents and improving the thermal stability of NCS, which is attributed to its rough matrix structure. This effect is attributed to the rough matrix structure of SA, which may offer greater resistance to water and enzyme penetration. The combination of 0.75% w/v SA + 0.25% w/v GG is found to be the most effective in reducing digestibility and enhancing thermal stability (p < 0.05), likely due to synergistic interactions between the two hydrocolloids. These findings provide valuable information on the effects of hydrocolloid matrices on the digestive properties of NCS and lay the foundation for future research.
