"Current research suggests that diets that are in carbohydrate may actually increase the risk of heart disease in some people because they sometimes lower HDL-C levels."

High in carbohydrates

Explanation:

Diets that are high in carbohydrates produces more sugar after digestion and leads to glycogenesis. This sugar exceeds the glycogen level of the body and it is converted to fat which increases the risk of heart diseases. High carbohydrate diet increases the risk of heart diseases as it is closely associated with insulin resistance, abdominal fat distribution, high plasma triglycerides level , low HDL -cholesterol and oxidative stress. High carbohydrate diets, especially refined carbohydrate causes weight gain with its associated problems such as cardiovascular diseases.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
