"Slowly digestible starch" (SDS) refers to starch that digests slowly throughout the small intestine, leading to a gradual and sustained release of glucose. This type of starch is beneficial for managing postprandial glycemic responses, as it helps in moderating blood glucose levels after meals. Various methods have been explored to enhance the slow digestibility of starch, such as enzymatic modifications that increase branching and solubility, resulting in improved slow digestion properties. Additionally, treatments like blanching potatoes in the presence of divalent cations have been shown to increase the fraction of slowly digestible starch in potatoes, offering a potential way to transform staple foods for healthier glycemic responses and sustained energy release. The pasta making process has also been found to influence starch digestibility, with pasta being identified as a good source of slowly digestible starch, aiding in glycemic control.What is the different between "slowly digestible starch" and "resistant starch" ?

"Slowly digestible starch" (SDS) and "resistant starch" (RS) differ in their digestion rates and physiological effects. SDS takes 20-120 minutes to be fully digested in the small intestine, providing a sustained release of glucose. In contrast, RS resists digestion in the small intestine, reaching the colon for fermentation into beneficial products like short-chain fatty acids. RS behaves more like a dietary fiber, promoting gut microbiome health and butyrate production. Physicochemical properties like amylose content and swelling capacity influence RS content, with high amylose content correlating with high RS levels and low swelling indicating high RS content. Additionally, RS from sources like black longan seeds can exhibit increased resistant starch content due to heat-induced structural changes, making them a potential source for food and related industries.What is the iron status of blood donor in malaysia?

The iron status of blood donors in Malaysia shows a significant correlation between serum ferritin levels and donation frequency. Regular donors exhibit lower ferritin levels compared to first-time donors, indicating iron deficiency due to repeated donations. Male regular donors have a higher prevalence of iron deficiency, while females show similar rates to male regular donors. Serum ferritin levels decrease with the number of donations, with 11% of regular donors having depleted iron stores. However, serum ferritin levels may not always accurately reflect iron overload, especially in patients with haematological malignancies due to inflammation and tissue necrosis. Haemoglobin levels do not consistently correlate with ferritin levels in blood donors. Regular monitoring of ferritin levels and iron supplementation post-donation are recommended to maintain the iron status of blood donors in Malaysia.What are the clinical symptoms of magnesium deficiency that can aid in diagnosis?
