Providing appropriate sustenance supplies the body with essential materials for biological processes. A calorie-controlled diet including a variety of nutrient dense foods from each major food group sets the framework for optimal health. By following recommendations set by the United States Food and Drug Administration (USDA), individuals can promote fitness and reduce disease. Adequate daily intakes of macronutrients, vitamins, and minerals through healthy food sources is necessary to maintain proper health.
Macronutrients and Proper Health
Macronutrients are crucial for proper health. Carbohydrates, protein, and fats are the primary nutrients needed for tissue growth, metabolism, and other internal functions (McGuire & Beerman, 2013). Beyond just calories, macronutrient balance is needed for wellbeing. There are many patterns o grouping of food which can provide a balanced diet within reasonable calorie margins.
In respect to the three macronutrients, the largest percentage of calories needed comes from carbohydrate group with a recommended ration of 14 grams per 1,000 calories (HHS, 2005). Carbohydrates are easily used throughout the body as fuel, in the form of glucose. Whole-grains, milk, fiber-rich fruits, and vegetables, without added sugar, are considered to be optimum sources for this macronutrient …show more content…
The USDA (2005) recommends that only 20 to 35 percent of calories should come from fat. Preferred sources are polyunsaturated and monounsaturated fatty acids. Food sources for these fatty acids include fish, nuts, and vegetable oils. Some fats are essential and cannot be manufactured in the body. However, saturated and trans-fatty acids intakes should be limited (PCRM, 2016). Flaxseeds, walnuts, wheat germ, and salmon are specific examples of foods which contain healthy fats, protein, carbohydrates and other valuable nutrients. Fat is important for the transport and uptake of fat-soluble
