Final answer:
Micronutrient supplementation can cure nutrient-specific deficiencies and must be consumed regularly due to the body's inability to store them. Overconsumption can lead to toxicity. It plays a role in disease prevention and might augment cancer treatments but is not universally proven to do so. Therefore, the correct option is B, C.
Step-by-step explanation:
The question is referring to the impact of micronutrient supplementation on human health. First, it is essential to distinguish between micronutrients and macronutrients. Micronutrients include vitamins and minerals that are necessary for the proper functioning of the body but are needed in smaller quantities compared to macronutrients like carbohydrates, lipids, and proteins. Regarding the options given in the question:
b is correct because micronutrient supplementation can cure nutrient-specific deficiencies. The body cannot store micronutrients in significant amounts, so they must be consumed regularly to prevent deficiencies.
c is also correct; overconsumption of some vitamins and minerals can lead to toxicity, with vitamin A and D being common examples where excessive intake can be harmful.
Furthermore, supplementation can sometimes play a role in preventing diseases by correcting deficiencies, but it's not accurate to claim that it prevents a multitude of diseases broadly. Additionally, while some studies suggest benefits of certain micronutrients in conjunction with cancer treatments, it cannot be universally stated that supplementation 'augments many cancer treatments' without specific, consistent scientific evidence.
