Answer:
conflict theory.
Explanation:
Conflict theories are perspectives in sociology and social psychology that emphasize a materialist interpretation of history, dialectical method of analysis, a critical stance toward existing social arrangements, and political program of revolution or, at least, reform. Conflict theories draw attention to power differentials, such as class conflict, and generally contrast historically dominant ideologies. It is therefore a macro-level analysis of society.
Karl Marx is regarded as the father of social conflict theory, which is a component of the four major paradigms of sociology. Certain conflict theories set out to highlight the ideological aspects inherent in traditional thought. While many of these perspectives hold parallels, conflict theory does not refer to a unified school of thought, and should not be confused with, for instance, peace and conflict studies, or any other specific theory of social conflict.
I suppose you mean proper nutrition. Main function of digestive system is to break down food and turn it in to energy. You have most probably heard about calories. So, 1 gram of Protein is 4 kcal, 1 gram of Carbohydrates is 4 kcal and 1 gram of Fat is 9 kcal. (also let's not forget that 1 gram of Alcohol is 7 kcal) Average male needs about 2000 to 2500 kcal a day to function properly (it's slightly less for females it depends on bodyweight, amount of muscle mass and activity level)
Along with water those are Macronutrients (carbs,protein and fat).
Micronutrients are vitamins and minerals essential for your body. For example Vitamin C, Iron, Zinc...
Now, proper nutrition is balanced diet filled with vitamins, minerals, quality sources of protein, carbs, fats and also filled with right amount of fiber which plays a vital role in your digestion by helping you with bowel movements and even lowering your blood cholesterol levels. So basically proper nutrition is connected to main function of digestive system in a way that by supplying your body with everything it needs, giving you right amount of energy it also keeps your whole body healthy at the same time.
