Final answer:
Nutritionists recommend reducing the intake of sugar and fat to stay within recommended energy intake from these sources and to support overall health. Carbohydrates are an essential nutrient, but should be consumed in balance with proteins and fats as part of a healthy diet.
Step-by-step explanation:
Nutritionists recommend that we reduce our intake of sugar and fat. It is advised to consume less than 10 percent of calories per day from added sugars and saturated fats, and to limit sodium intake to less than 2,300 milligrams per day. Making healthy food choices involves selecting options with less sodium, saturated fat, and added sugars. Reducing the consumption of refined carbohydrates like sweets and sugary drinks while increasing the intake of fiber-rich foods such as fruits, vegetables, and whole grains is also recommended.
Carbohydrates are important for biological functions as they are a primary component of food along with proteins and fats. They're necessary for cellular function and the provision of energy, as food intake in excess of immediate energy needs is stored as glycogen in the liver and muscle cells, and in adipose tissue. Excess storage of adipose can lead to obesity and serious health issues.
In terms of nutrient balance, it is generally recommended to obtain 10-15% of total calories from protein, 20-30% from fat, and 50-70% from carbohydrates. To support a healthy diet, one should also limit sugar and salt intake, limit saturated fats while choosing foods with beneficial fats such as omega-3 fatty acids, and combine plant foods to create complete proteins.
