What are the substances in food that promote normal growth maintenance and repair in your body?
Nutrients are vitamins, minerals, carbohydrates, proteins, fats, and water. These six essential nutrients are something we all need for growth, energy, and for maintenance and repair of our cells.
What promotes growth maintenance and repair?
Nutrients are substances obtained from food and used in our bodies to promote growth, maintenance, and repair. There are six classes of nutrients that our body needs to function: carbohydrates, protein, fat, water, vitamins, and minerals.
What nutrient gives growth and repair?
Nutrients
| Nutrient | Use in the body |
|---|---|
| Protein | For growth and repair |
| Lipids (fats and oils) | To provide energy. Also to store energy in the body and insulate it against the cold. |
| Minerals | Needed in small amounts to maintain health |
| Vitamins | Needed in small amounts to maintain health |
What nutrient is the body’s main source of energy?
Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.
What food will you take to help delay fatigue?
Some quick options include:
- Whole grain bagel with cheese.
- Cereal with fruit and yogurt.
- Whole grain toast with peanut butter and fruit.
- Hard-boiled egg sliced into a whole wheat pita.
- Scrambled eggs, toast, and fruit.
- Oatmeal with raisins.
Which is not an essential nutrient in the body?
Essential nutrient: cannot be made by the body in sufficient quantities to meet the body’s needs. They must be obtained by the diet. “Essential” does not equal required. Essential and nonessential nutrients are both vital for normal functioning. calorie: energy required to heat 1g of H2O at 1 degree celsius.
How are carbohydrates converted to nutrients between meals?
Explain the concept of amino acid or carbohydrate-fat pools, and describe pathways by which substances in these pools can be interconverted. We have nutrient pools – stores of nutrients – that we can rely on between meals. Many of the nutrients can be interconverted – converted from one form to another (mostly done in the liver).
How are proteins used in the human body?
Proteins are important structural materials of the body, while others function as enzymes and hormones. Proteins are not normally used for energy sources. Vitamins – found in all major food groups. You must have a balanced diet to get all vitamins. Most vitamins function as coenzymes which help enzymes do their function. Nice work!
Why are incomplete proteins considered to be nutritionally incomplete?
Incomplete proteins are nutritionally incomplete because they are low in one or more of the essential amino acids. Nitrogen balance is a homeostatic state. The rate of protein synthesis equals the rate of protein breakdown and loss in healthy adults. Distinguish between fat- and water-soluble vitamins, and list the vitamins in each group.
