Study Notes

Nutrition

  • Nutrition refers to nourishment that sustains life, encompassing physical, social, and personal aspects.
  • Nutrition is the science and art of nourishing human life, from conception to death.
  • Proper nutrition supports optimum growth, mental well-being, and resistance to disease.
  • Diet plays a role in promoting health and reducing the risk of many conditions, from low birth weight to cancer.
  • Energy is needed for vital functions like breathing, and physical activity.
  • Food nourishes the human spirit, with "soul food" providing comfort and psychological/spiritual well-being.
  • Nutritional science defines nutritional requirements for body maintenance, growth, activity, and reproduction.

Food and Health

  • Recent discoveries about the health aspects of certain foods have led to government regulations and food labels.
  • Food labels that describe health benefits are important for consumers, but may lead to questions about the relationship between food and health.
  • "Function foods" are foods purported to have health benefits over their nutritional value.

Nutrition and Health Promotion

  • Preventing and controlling chronic diseases is important for health professionals.
  • Advancements in sanitation and public health have led to declines in deaths from diseases like tuberculosis and pneumonia.
  • Heart disease, cancer, and stroke remain leading causes of death in developed countries.
  • Preventative behaviors like sound nutrition and physical activity are important for maintaining and improving health.
  • About 50 nutrients are considered essential for human life and health.
  • Knowledge of essential nutrients (carbohydrates, fats, proteins, vitamins, minerals) is vital, especially for developing formulas for enteral and parenteral nutrition.

Nutrient Interrelationships

  • Nutrients interact in complex ways.
  • Individual nutrients have specific roles in the body
  • Nutrients work together
  • No nutrient works alone

Energy Sources

  • Carbohydrates, fats, and proteins are primary sources of energy for the body.
  • Carbohydrates, primarily starches and sugars, are the body's main fuel source.
  • One gram of carbohydrate yields 4 kilocalories.
  • Fats provide an alternative/storage form of energy, yielding 9 kilocalories per gram.
  • Proteins provide 4 kilocalories per gram and are primarily for building tissue, but can be used for energy when needed.

Vitamins

  • Vitamins are needed in small amounts but are essential.
  • Vitamins have important roles for tissue formation and function (e.g., vitamin C, vitamin A).

Minerals

  • Minerals have diverse roles in building tissues and supporting bodily functions.
  • Examples include calcium and phosphorus, which strengthen bone tissue.
  • Iron is necessary for enzyme actions in mitochondria.

Water

  • Water is a vital nutrient for all life processes.
  • Its roles include regulating bodily processes, forming blood and lymph, and transporting nutrients/removing waste.

Metabolic Regulation and Control

  • Body's metabolism and required energy processes must be controlled.
  • Vitamins and minerals play essential roles in regulating metabolism and maintaining homeostasis.
  • Water provides an environment for chemical reactions.

Levels of Nutritional Status

  • Nutritional status reflects an individual's general health.
  • Varied levels of nutritional status exist.
  • Ideal nutritional status (optimum) involves well-being and good health.
  • Health professionals aim for ideal nutritional status.
  • Ideal nutrition is characterized by body composition, appearance, and body function.

What Causes World Hunger?

  • Food insecurity and hunger cause stunting and malnutrition, especially among children.
  • The world produces enough food for all people but significant portions go hungry.
  • Poverty, food shortages, war and conflict, climate change, are some of the leading factors.

Poor Nutrition

  • Hunger and malnutrition are linked to a lack of access to essential nutrients.
  • Staple foods like grains or corn may not provide a sufficient variety of nutrients.
  • Pregnant women and young children are especially vulnerable to malnutrition.

Forced Migration

  • Forced migration, driven by factors such as hunger, can further contribute to existing or create new causes of malnutrition and food insecurity.
  • Refugees in neighbouring countries often face resource constraints.

Malnutrition

  • Malnutrition includes deficiencies, excesses, or imbalances in nutrient intake, leading to various conditions.
  • Undernutrition involves stunting, wasting, and micronutrient deficiencies (lack of vitamins & minerals).
  • Conditions like overweight, obesity, and chronic illnesses are also examples of malnutrition.
  • Protein-energy malnutrition (PEM) results in inadequate protein and energy intake, frequently affecting children.
  • Kwashiorkor and marasmus are specific forms of PEM, representing acute protein deficiency and energy deficiency, respectively.
