Study Notes
Nutrient Importance
- Kidneys play a crucial role in regulating several essential minerals: Iron, Zinc, Selenium, Manganese, Copper, Iodine, Molybdenum, Cobalt, Chromium, and Fluorine.
- Each mineral has unique health benefits, contributing to physiological functions and overall well-being.
Factors Affecting Nutrition
- Nutrition choices are driven by hunger but influenced by various determinants beyond physiological needs.
Major Determinants of Food Choice
- Biological Factors: Physiological needs for energy and nutrients dictate food choices; central nervous system regulates hunger and satiety.
- Economic and Physical Factors: Cost of food significantly impacts choices, particularly for low-income individuals; there’s often a fear of food wastage when trying new foods, leading to unbalanced diets with low fruit and vegetable intake.
Eating Disorders
- A desire to lose weight or change body shape can lead to unhealthy dieting and exercise practices.
- Eating disorders often stem from a combination of biological, psychological, familial, and socio-cultural factors.
- Symptoms include distorted self-image, low self-esteem, anxiety, obsession, stress, and unhappiness.
Consumer Attitudes and Beliefs
- Attitudes towards dietary fats have shifted over decades, resulting in reduced fat consumption and changes in fat types (saturated vs. unsaturated).
- An understanding of food impacts health can influence dietary habits and preferences.
Barriers to Dietary Change
- Household income is a crucial barrier to healthy food choices; low-income consumers often face restrictions leading to nutritional inadequacies.
- Loss of cooking skills and lack of knowledge also hinder the preparation and purchasing of healthy meals.
The Age of Biotechnology
- Biotechnology has rapidly evolved over the last 20 years, enabling precise genetic modifications in organisms.
- Agricultural biotechnology has significantly progressed, allowing for enhanced crop breeding through genetic techniques.
Health and Nutrition Interrelationship
- High-fat foods can aid muscle movement but should be balanced with calorie-burning activities to mitigate risks of heart disease and diabetes.
- Controlled fat intake can lead to health improvements, notably in brain function.
Minerals in Nutrition
- Calcium (Ca): Essential for strong bones; important in drug therapies.
- Glucosides: Used in cardiac therapy and steroid hormone production.
- Insulin: Utilized in assessing kidney function.
- Heparin: Important for preventing blood clotting.
Low Food Intake and Health Issues
- Malnutrition can arise from food scarcity or difficulty in nutrient absorption, often exacerbated by oral health issues like poorly fitting dentures.
Mental Health Connections
- Undernutrition can influence mental health problems, including depression, dementia, and anorexia nervosa.
Classification of Sugars
-
Monosaccharides: Simplest form of sugars (one sugar molecule); cannot be hydrolyzed further.
- Hexoses are prominent monosaccharides, with glucose being a significant type, known as blood sugar.
- Oligosaccharides: Composed of 2-10 simplistic sugars upon hydrolysis.
- Disaccharides and Others: Formed from two monosaccharides; further classifications exist.
Summary of Alternatives
- Mannitol, Xylitol, Glycerol, Inositol, and Ascorbic Acid have distinct roles as food ingredients and health benefits.
