Study Notes
Nutrient Definition and Purpose
- Nutrients are substances plants and animals need for survival and growth. They come from food and drinks.
- Each nutrient has a specific role in maintaining health and bodily functions.
- Knowledge of nutrients helps to plan and prepare meals and understand recommended food groups.
- Essential nutrients are crucial for the body's needs.
Macronutrients
- Macronutrients are needed in larger amounts for energy.
- Carbohydrates are broken down into glucose, the body's primary energy source.
- Simple carbs (sugars) are quickly digested, providing quick energy but potentially followed by energy crashes and cravings. Found in fruits, dried fruits, sugar beet, vegetables, honey, sugar cane.
- Complex carbs (starches) release energy slower, aiding in satiety and maintaining energy levels. Found in potatoes, bread, pasta, rice couscous, oats, beans, peas, porridge, museli and lentils
- White carbs (simple) have less fibre and vitamins compared to whole grains (complex)
- Fats provide a concentrated energy source, especially beneficial for long-duration, low-intensity activities.
- Healthy fats protect organs, repair tissue, and regulate body temperature.
- Fats contain essential fatty acids and aid vitamin absorption.
- Saturated fats are typically solid at room temperature and found in animal products (milk, meat, cheese, butter), some processed foods, and some plant products.
- Unsaturated fats (monounsaturated and polyunsaturated) are liquid at room temperature and found in sources like olive oil, avocados, fatty fish, nuts, and seeds.
- Cholesterol is a fatty substance produced by the liver, transported in the blood.
- LDL (low-density lipoprotein) is considered "bad" cholesterol, increasing heart disease risk, and can lead to artery blockages.
- HDL (high-density lipoprotein) is "good" cholesterol, helping remove excess cholesterol.
Micronutrients
- Micronutrients (vitamins and minerals) are needed in smaller quantities for various bodily functions.
- Vitamins are categorized as either fat-soluble (stored in the body) or water-soluble (not stored).
- Fat-soluble vitamins include A, D, E, and K.
- Water-soluble vitamins include B and C
- Minerals are categorized as macrominerals and trace minerals, depending on the needed amounts. -Macrominerals: in larger quantities, e.g. Calcium -Trace minerals: in small quantities, e.g. Iron
Importance of Water & Fibre
- Water is essential for bodily functions, including nutrient transport and temperature regulation.
- Adequate water intake helps to maintain hydration levels.
- Fibre is a non-digestible plant compound that aids in digestion and may help regulate cholesterol.
- Sources of fibre include whole grains, oats, fruits, and vegetables. Fibrous foods can aid in reducing cholesterol levels.
Factors Affecting Nutrient Needs
- Factors like age, sex, activity level, and health status influence individual nutrient requirements.
- Specific needs rise during pregnancy or for certain medical conditions.
