Study Notes
Food and Digestion
- Lipids are fats, either solid or liquid at room temperature
- Plant lipids are usually liquid and called oils
- Animal lipids are usually solid and called fats
- Lipids are made of glycerol and fatty acids
- Lipids store energy, insulate the body, and protect organs
Lipids
- Lipids make up about 10% of the body's mass
- Lipids are a long-term energy store
- Fat acts as insulation, reducing heat loss
- Fat around organs protects them from damage
- Saturated fats are more common in animal products
- Unsaturated fats are more common in plant oils
- Saturated fats are less healthy than unsaturated fats
Proteins
- Proteins are polymers made of amino acids
- Proteins are essential for growth and repair
- Proteins can be enzymes or structural components
- Proteins are about 18% of the body's mass
- Protein deficiency can lead to kwashiorkor
- Recommended daily protein intake is about 70g
- Essential amino acids must be obtained from food
Minerals
- Minerals are chemical elements needed by the body
- Minerals are in our food as mineral ions
- Minerals are used for a variety of bodily functions, including bone growth
- Minerals required by the body in large amounts include calcium and phosphorus
- Minerals required by the body in smaller amounts include sodium, chlorine, magnesium, and iron
- Calcium and phosphorus build teeth and bones
- Sodium and Chlorine are found in body fluids
- Magnesium makes bones and is part of cells
- Iron is part of haemoglobin, carrying oxygen
Essential Amino Acids
- 10 amino acids are essential amino acids
- Essential amino acids must be obtained from food
- Meat, fish, eggs, and dairy products have high amounts of essential amino acids
- Vegetarians can obtain essential amino acids from plant products
