Micronutrients are essential nutritional elements that assist the body in synthesizing enzymes, coenzymes, prosthetic groups, hormones, and other compounds important for living beings' progress and expansion. Trace elements are one of the important part of micronutrients. Trace elements have an important impact on human health and have a wide range of metabolic properties and performance, although these elements constitute a small part of the biological tissues. Immune modulation by humoral and cellular mechanisms, nerve conduction, muscular contractions, membrane potential regulation and mitochondrial functioning and enzyme responses are just a few of the activities that trace elements perform in tissue, cellular and subcellular processes. In type 2 diabetes, selenium, chromium, zinc, calcium, magnesium, sodium, manganese, cobalt, iodine and iron levels appear to be low, iron and vanadium deficient, whereas potassium and copper levels remain unaffected. Numerous different micronutrients, such as zinc, iron, copper and selenium, are now required by the complicated, interconnected immune system that plays significant, often complementary roles at each and every stage of the immune response. This research is focused on micronutrients, such as zinc, selenium and chromium, playing an important role as anti-diabetic and immunomodulatory agents and their availability in the edible parts of green leafy vegetables of West Bengal.
INTRODUCTION:Trace elements are essential micronutrients for the correct functioning of human body as they significantly impact metabolic and physiological processes. Micronutrients are composed of trace minerals, macro-minerals, vitamins, and organic acid. Iron, copper, zinc, manganese, iodine, chromium, and selenium are trace elements or minerals, while calcium, phosphorus, potassium, sodium, and magnesium are significant macro minerals for humans.
