1. The correct choice is A.) Carbohydrates
During digestion, the body converts carbohydrates in food into glucose. This glucose enters the bloodstream and serves as direct energy for bodily functions. It can also be stored as glycogen in the liver or muscles.
The term for the level of glucose in the blood is blood glucose. Typical fasting glucose levels range from 0.6 g/l to 1 g/l. After eating, blood sugar can rise for one to two hours, not surpassing 1.6 g/l, and returns to normal within two hours.
2. The appropriate answer is D.) Iron
Iron plays a crucial role in supporting the immune system. It facilitates the absorption of nutrients from food and aids in delivering oxygen to injured areas of the body, which are more susceptible to infections.
Iron is necessary for making hemoglobin, a protein found in red blood cells that transports oxygen throughout the body.
3. The correct answer is A.) helps the body process the nutrients we consume.
Water is vital for living organisms, as the majority of it resides within cells. Another portion is in the intercellular space, acting as a reserve for blood and cells. The remainder is found in the blood and lymph, circulating continuously throughout the body.
Besides being a fundamental cell component, water carries out several functions:
- it takes part in numerous chemical reactions of the human body,
- it transports various dissolved substances essential for cells,
- it aids in removing metabolic waste,
- it helps regulate the body's internal temperature.
4. The best option is A.) Whole wheat pasta with a Bolognese or vegetarian sauce served with bread.
To enhance glycogen reserves is vital for extended physical activities, as these reserves determine how long sustained effort can be maintained. This idea is referred to as capacity. Therefore, factors that positively influence glycogen stores include:
the initial level of storage; if muscle fibers are depleted of glycogen, they will absorb more sugar due to the "overcompensation" phenomenon;
the training intensity; a more conditioned athlete can store better due to increased insulin sensitivity;
the diet; a carbohydrate-heavy diet encourages glycogen resynthesis, particularly within the first hours following exercise (8 to 12g/kg/d). Benefit from metabolic opportunities after recent workouts, which are often less intense, to maximize your glycogen stores.
5. The correct choice is C.) vitamin D
* Dairy products are an excellent source, including cheese, yogurts, and milk. Here are some equivalents for equal calcium content:
30g of cheese = 150ml of milk = 100g of cottage cheese.
* Fish are also a source of calcium.
In a standard 150g serving of fish, there is typically 150mg of calcium.
6. The right answer is B.) Tomatoes, strawberries, and peppers.
* Peppers are particularly rich in vitamin C, just behind parsley, and ahead of cabbages and spinach, providing 126mg per 100g, meaning a modest 50g portion delivers 75% of the daily recommended intake.
* Raw tomatoes additionally provide vitamin C, with 100g offering 19.38% of the Nutritional Reference Values (NRV) in vitamin C (approximately 15.50 mg per 100 g).
7. After thorough research, it's determined that the foods mentioned are equally high in iron and magnesium, making both answers valid (deficiencies in both iron and magnesium can occur).
* Hazelnuts serve as a rich source of magnesium for women and a source for men, their requirements differing.
* Hazelnuts provide iron as well for men and are also a source for women, given their differing needs. Iron is present in every cell of the body.
Similar conditions apply to red meats and various vegetables (some are rich in magnesium, while others contain iron).
