Question

Is it possible for something to be beneficial to human health at low doses but detrimental at high doses? Name at least three chemicals that might be good and bad, depending on the dose. Can something be good at high doses and detrimental at low doses?

Answer 1

We must remeber everything can act as poison depending upon dose. A substance benificial at low dose can be harmfull at high dose. The best example is the medicine we take. Most of the medicine that we take is benifificial at low dose only. At high dose these medicines may cuse death. Similarly many nutrients like Ca²⁺ Fe²⁺ are benificial only at low dose. Vitamins are also required in lower quantities, a high dose of vitamins also may be detrimental to health.

The carbohydrates , protiens, fats etc must be taken adequately by humans. Their low dose is harmfull to health.
