Question

How many calories are provided by a food that contains 29 grams of carbohydrate, 6 grams of protein, and 1 gram of fat?

Answer 1

The food item containing 29 grams of carbohydrates, 6 grams of protein, and 1 gram of fat provides a total of 149 Calories.

Step-by-step explanation:

To calculate the caloric content of a food item based on its macronutrient composition, we use the fact that proteins and carbohydrates both provide approximately 4 Calories per gram, while fats provide about 9 Calories per gram. Using this information:

• 29 grams of carbohydrates will provide (29 g × 4 Cal/g) = 116 Calories.
• 6 grams of protein will provide (6 g × 4 Cal/g) = 24 Calories.
• 1 gram of fat will provide (1 g × 9 Cal/g) = 9 Calories.

Adding these together gives a total caloric content of 116 + 24 + 9 = 149 Calories for the food item.

Answer 2

Energy (caloric) value of foods is indicated by calories, which measure the amount of heat that the food releases in the metabolic process. In physiology, it is determined by the energy balance of the organism, ie the heat exchange between the organism and the external environment.
Calories of nutrients:
1 g of protein = 4 kcal (kilocalories)
1 g of fat = 9 kcal
1 g of carbohydrates = 4 kcal
1 g of alcohol = 7 kcal
1 g of organic acid = 3 kcal

According to the table above, we can calculate required value:

29x4 + 6x4 + 1x9= 149 kcal/g
