Step-by-step explanation:
This question mixes knowledge concerning health and concerning linguistics/grammar. Let's take a look at each of the sentences.
A. We need an adjective for the noun "diet". Since "health" is also a noun, the correct option is "healthy".
B. Having too much salt means a certain food is not good for your health. If crisps aren't good, then the option we should choose is "high".
C. Eggs, just like meat and chicken, are rich in protein. People who wish to build muscles usually consume lots of eggs every day.
D. If we are thinking of the health of our teeth and bones, we are thinking of calcium. That is what they need to be strong.
E. While red meat is high in fat and should be avoided for that reason, fish is a low-fat food, and should be preferred.
T. We have all heard of the importance of a balanced diet. You can eat a bit of everything that is in the food groups and be healthy.
S. The phrase we are looking for is "in moderation". "On" does not fit the expression at all.
