Studies of populations that reveal correlations between dietary habits and disease incidence are epidemiological studies.
Inadequate dietary vitamin D or its deficiency leads to malabsorption of calcium. Nutritional disorder leads to the rare disease rickets, which causes bones to become soft and bend in children. In adults, vitamin D deficiency leads to osteomalacia, which causes weak bones, bone pain and muscle weakness.
The body needs vitamin D to properly absorb calcium and phosphorus from the diet. However, keeping the right quantities of calcium and phosphorus in bones is challenging when vitamin D levels are low.
The two sources of vitamin D are-
- Natural sunlight
- Foods such as fish oil, Egg yolk and fatty fishes like salmon and mackerel
There are other disease conditions which lead to poor absorption of vitamin D-
- Inflammatory bowel disease
- Celiac diseases
- Kidney problems

Answer:
Additive effects
Explanation:
In pharmacology, sometimes more than one drug is used to treat a disorder. The two or more drugs are used as they treat the disease more effectively than they treat the disorder independently. The two drugs interact in one of the two ways: the additive effect and the synergistic effect.
In the given question, the drugs when combined produce the sum of the drugs equal to the effect shown by the drugs individually therefore the effect of the drug is added.
This type of drug interaction is known as the additive effect.
Thus, Additive effect is the correct answer.
