Answer 1

1. Long-term use of antibiotics can result in a deficiency of vitamin K because it reduces its absorption and also kills the essential microbes that make vitamin K.

2. Overdosing on beta-carotene nutrients can cause the skin to turn yellow-orange because it is a fat-soluble nutrient and generally accumulates in the outermost layer of the skin.

3. Bogus vitamins are the substances that are claimed to be vitamins but are not vitamins actually. a different sales person promotes them as vitamins for their benefit. for example - coenzyme Q10.

4. Storing fruit by freezing method causes the greatest loss of vitamin C.

5. Nuts are a good source of dietary fiber and vitamin E.

6. The leading cause of blindness in most developing countries is Vitamin A deficiency. its deficiency causes cornea to become dry which results in the vision loss.
