In this study, we analyzed the concentration of dietary mineral viz. calcium, magnesium, phosphorus, potassium and sodium in fresh tender shoots of seven locally available bamboo species and their three processed products. It revealed considerable concentration of the fve essential minerals in both fresh and processed products, where their concentration was comparatively high in fresh shoots than that of processed products, irrespective of the species. Contributions of 100 g fresh bamboo shoot and their processed products to Daily Value Requirement (DV%) of the fve essential minerals were very impressive (Anonymous 2016). Such contribution for the fve essential minerals to DV% was considerably high for both fresh tender shoots and their processed products, which were comparable to other conventional foods. Therefore, in addition to our conventional foods, regular or occasional consumption of fresh and processed bamboo shoots may be very efective to meet the Daily Require- ment Value of these fve essential minerals.

From dietary point of view, minerals are required in sufcient quantity for the regulation of our body processes and maintaining good health (Anonymous 2016). Various functions of minerals include building stronger bones and transmitting nerve impulses. A few of the miner- als are incorporated in synthesizing hormones and also help in maintaining normal heartbeat. Calcium and phosphorus are most important minerals for human health attributed to formation of teeth and bones, where a proper level of both prevents osteoporosis (Sunyecz 2008). Magnesium is required for maintaining normal nerve and muscle func- tion, supporting a healthy immune system and maintaining a steady heartbeat and blood sugar level. Magnesium is also a cofactor for more than 300 enzyme systems that regulate diverse biochemical reaction with 3751 binding sites on human protein, indicating its importance in human health and disease management (Anonymous 1997; Rude 2012; Mercola 2015). Potassium is another essential mineral that helps in nerve and muscle function and transportation of other nutrients, where its defciency is also linked to cardio- vascular diseases and other critical illness (Anonymous 2021). A diet rich in potassium helps to increase sensory taste of foods, rise in free fatty acids and ofset harmful efects of sodium (Lindsay et al. 1982). Both potassium and sodium help in maintaining optimum level of hydration of living tissues, however, higher level of sodium in body may subject to critical health issues (Nomura et al. 2019). * Ch.
