“…However, decreased serum T-CHO and TG levels in mammals was observed by Behall et al (1988) and Denardin et al (2012), whereas the opposite effect was observed by Yin et al (2011) in weaned pigs after the consumption of a diet rich in amylose compared to a diet rich in amylopectin. The reason for this difference is unclear in that the dietary starch level was identical for each experiment besides protein and lipid level.…”

A feeding trial was conducted in tilapia to determine the growth performance, nutrient digestibility, digestive enzymes, and postprandial blood metabolites in response to different dietary amylose-amylopectin ratios. Five isonitrogenous and isolipidic diets containing an equal starch level with different amylose-amylopectin ratios of 0.11 (diet 1), 0.24 (diet 2), 0.47 (diet 3), 0.76 (diet 4) and 0.98 (diet 5) were formulated using high-amylose corn starch (as the amylose source) and waxy rice (as the amylopectin source). Each diet was hand-fed to six tanks of 15 fish each, three times a day over a 6-wk period. After the growth trial, a postprandial blood metabolic test was carried out. Fish fed diet 2 exhibited the highest percent weight gain and feed efficiency and protein efficiency ratio, whereas fish fed with diet 5 showed the lowest growth and feed utilization among treatments. The digestibility for starch in fish fed diet 1 and 2 was higher than those in fish fed with other diets (p<0.05). The highest activities for protease, lipase and amylase were found in fish fed the diet 2, diet 1, and diet 1 respectively among dietary treatments, while the lowest values for these indexes were observed in fish fed the diet 3, diet 5 and diet 4, respectively. The liver glycogen concentrations in fish fed diets 4 and 5 were found higher than in fish fed other diets (p<0.05). The feeding rate, hepatosomatic index, condition factor, and plasma parmeters (glucose, triglyceride, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol) did not differ across treatments. In terms of postprandial blood responses, peak blood glucose and triglycerides were lower after 3 or 6 h in the fish fed with diets 3–5 than in the fish fed diet 1, but delayed peak blood total amino acid time was observed in fish fed with the diets 1 or 2. The lowest peak values for each of the three blood metabolites were observed in fish fed diet 5. The results indicate that high-dietary amylose-amylopectin ratio could compromise growth, but help in reducing the blood glucose stress on fish caused by postprandial starch load.

“…The RS predominantly consists of amylose, which is hydrolyzed relatively slowly compared to amylopectin . Hence, high‐amylose food is digested slowly in the human gut resulting in release of insulin over a long period, which is reflected in relatively low GI values . Granule bound starch synthase I (GBSS I) is the key enzyme for the elongation of amylose chains .…”

“…Thus, RS content is negatively correlated with GI. High amylose rice varieties are also reported to have low GI values compared to the low amylose types . But many of the indica varieties in spite of their intermediate to high AC (20–30%) show relatively high glycemic response .…”

Low light stress influences resistant starch content and Glycemic index of rice ( O. sativa L)

et al. 2019

Low light (LL) stress is an important abiotic stress of wet season which adversely affects starch biosynthesis and results in drastic reduction in rice grain yield. In general, the grain yield decreases together with reduction in the amylose (AC) and resistant starch (RS) contents while the glycemic index (GI) values increased in plants exposed to LL stress. This is the first report of the effect of LL stress on RS and GI values. In the present investigation, 14 rice genotypes are studied for the effect of LL stress on AC, RS, and GI of the grains. Rice genotypes, Purnendu and Shashi differ in exhibiting relatively much lower reduction in AC and RS and hence little change in their GI values under LL stress, while wide variation is observed for the rest of the genotypes. The grain yields of Purnendu and Shashi are also not much affected by the LL stress. There is a dramatic increase in the expression levels of the gbssI in the middle stage of grain development in the two genotypes (Purnendu and Mahisugandha with contrasting RS, AC, and GI). Maximum expression of the gene was observed in Purnendu at middle stage showing a positive correlation between RS and gbssI expression. As rice is grown mainly in wet season, the identification of rice genotypes which do not permit much change in RS value when grown under LL and hence no significant increase in the GI value, would help to develop better rice varieties for consumption by diabetics.

“…This was consistent with previous studies where white rice were always considered as high GI foods and GI values of more than 80 were typical (Brand-Miller et al, 1992;Barakatun-Nisak et al 2005). Wide differences in digestibility and GI values of white rice have been ascribed to various factors, including amylose and amylopectin ratio which are important molecules that determine the structure of the rice (Denardin et al, 2012). The structure of the rice can have a profound effect on the rate of digestibility and the response in blood glucose to the rice (Denardin et al, 2012).…”
