Study Notes
Nutrition Concepts
- Nutrition is the science that studies food and how the body utilizes it.
- Nutrients provide energy and are essential for growth and bodily functions.
Types of Nutrients
- Carbohydrates include starches, fibers, and sugars; they are primary energy sources.
- Glucose is a simple sugar vital for providing energy to the body's cells.
- Fructose is a natural sugar found in fruits and honey, often added to drinks.
- Lactose, or milk sugar, is produced by mammals.
- Sucrose is commonly known as table sugar, derived from sugar cane.
- Glycogen is a complex carbohydrate stored in the liver and muscles for energy.
- Fiber contributes to digestive health by adding bulk to waste.
Fats and Cholesterol
- Fats are energy-dense nutrients and the main energy storage form.
- Cholesterol is essential for producing Vitamin D and bile; the body synthesizes it.
- High-Density Lipoproteins (HDL) transport cholesterol to the liver, known as "good cholesterol" for reducing heart disease risk.
- Low-Density Lipoproteins (LDL) deliver cholesterol to cells, contributing to plaque buildup.
Proteins and Amino Acids
- Proteins, made from amino acids, are crucial for building, repairing tissues, and regulating bodily processes.
- Essential Amino Acids are nine amino acids that must be obtained from food.
Vitamins
- Vitamins support health in small amounts; they are categorized as water-soluble or fat-soluble.
- Vitamin A is critical for bone health; deficiency can lead to blindness.
- Vitamin D is synthesized through UV exposure; it is vital for bone health.
- Vitamin E promotes healthy skin, hair, and nails.
- Vitamin K plays a key role in blood clotting.
- Vitamin C, or Ascorbic Acid, is water-soluble and aids in energy processes.
Minerals
- Minerals are essential chemical elements for enzyme function, bone health, and other bodily processes.
- Nutrient Deficiency occurs when insufficient amounts of a nutrient impair health.
- Nutrient Density assesses the nutritional value of a food relative to its energy content.
- Sodium regulates fluid levels in the body and is necessary in small quantities.
- Calcium supports cell reproduction and bone strength.
- Iron is critical for hemoglobin production in red blood cells.
Hydration and Health Conditions
- Water is the most crucial nutrient; at least 8 cups daily are recommended to maintain hydration.
- Dehydration occurs when water loss exceeds intake, affecting body functions.
- Anorexia Nervosa is an eating disorder leading to significant weight loss due to fear of gaining weight and distorted body image.
- Bulimia involves cycles of binge eating followed by purging to prevent weight gain, driven by a loss of control.
