Study Notes
Nutrients and Nutrition
- Nutrients are chemicals compounds in food that are used by the body to function properly and maintain health.
- Examples of nutrients include proteins, fats, carbohydrates, vitamins, and minerals.
- Nutrition is about eating a healthy and balanced diet to provide energy and nutrients for overall health.
Types of Fats
- Polyunsaturated fat is a type of fat that is liquid at room temperature.
- There are two types of polyunsaturated fatty acids: omega 6 fatty acids (found in liquid vegetables like corn oil and soybean oil) and omega 3 fatty acids (found in plant sources like canola oil, flaxseed, and walnuts).
- Saturated fat is a type of fat that is solid at room temperature, found in full-fat dairy products (like butter, cheese, cream, and whole milk).
Importance of Protein
- Protein is found in every living cell in the body and is necessary for building and maintaining bones, muscles, and skin.
- Protein can be obtained from meat, dairy products, nuts, and certain grains and beans.
Sodium and Blood Glucose
- Sodium is an essential element that helps with nerve and muscle function and maintains fluid balance in the body.
- Table salt is made up of sodium and chlorine, and is also known as sodium chloride.
- Blood glucose, also known as blood sugar, is the main sugar found in the blood and provides energy for the body.
Calories and Carbohydrates
- Calories are a unit of energy found in food, and are provided by carbohydrates, fats, proteins, and alcohol.
- Carbohydrates are broken down into glucose (blood sugar) in the digestive system, which is then used by the body for energy.
Importance of Good Nutrition
- Good Nutrition means eating a balanced and healthy diet to ensure the body gets the necessary nutrients, vitamins, and minerals.
- Good Nutrition is essential for reducing the risk of diseases, improving overall health, and maintaining energy levels.

- Macronutrients (carbohydrates, protein, and fat) provide energy and maintain the body's structure and systems.
- Micronutrients (vitamins and minerals) are vital for healthy development, disease prevention, and well-being, and are needed in small amounts.
- Food also supplies phytochemicals that serve various functions to ensure the body operates optimally.
