Nutrients Need

Introduction

The benefits of good nutrition to health maintenance is a important to the elderly as it is to young. Many older adults have special nutrient requirements because aging affects absorption, use and excretion. A combination of macronutrients, vitamins and minerals, fiber and water are essential in providing the nutrients for the elderly.

Macronutrient

  • Macronutrient constitutes the majority of an individual diet’s, “supplying energy and the essential nutrients needed for health, maintenance”.
  • Macronutrients are nutrients that provide calories or energy. There are three macronutrients which are carbohydrate, protein and fats.
  • Each of these macronutrients provides calories and their amount varies:
    • Carbohydrate provides 4 calories per gram
    • Protein provides 4 calories per gram
    • Fat provides 9 calories per gram

Dietary fibre

Dietary fibre constitutes parts of plant that are not digested by the human body. It is found only in plant foods such as fruits, vegetables, nuts and grains. There are two types of fiber. They are soluble and insoluble fiber. Insoluble fiber binds water, so it helps to increase bulk, soften stool and shorten transit time through the intestinal tract.

Health benefits of dietary fiber.

Among the health benefits of dietary fibre include:

  • Prevent Constipation
  • Lower blood cholesterol level.
    • The body eliminates cholesterol through the excretion of bile acids. Soluble fiber binds bile acids, suggesting that a high fiber diet may result in the excretion of cholesterol.
  • Reduces the risk of cardiovascular diseases and some cancers (e.g colon cancer)
