Foods contain fats, carbohydrates and proteins. These nutrients provide energy and this energy is measured in kilocalories. Vitamin A is also a nutrient but it is not a fat, carbohydrate or protein. It is not measured in kilocalories. So, the answer to your question is that vitamin A contains 0 grams of kilocalories.
If you are talking about getting 100 calories from pure protein, there are 25 grams of protein. However, a lot of foods have a mixture of protein, carbohydrate, and fat. So this isn't necessarily the case with all foods. Take a look at the nutrition fact label to see how many grams of protein/fat/carbohydrate are in each serving. 1g protein=4 calories 1g carbohydrate=4 calories 1g alcohol=7 calories 1g fat=9 calories
Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram. So, the total number of calories in the food would be (20 grams carbohydrate x 4) + (8 grams protein x 4) + (5 grams fat x 9) = 80 + 32 + 45 = 157 calories.
No. Both one gram of protein and one gram of carbohydrates contain 4 calories.
A carbohydrate is mass, and "gram" is a unit to measure the weight of mass. So any given mass of carbohydrate will have a weight measurable in grams. For instance, 1 cup of corn weighs 166 grams. Of that weight, 123 grams are carbohydrates. I think your real question may have been, "How many calories in a gram of carbohydrate?" This is a little tricky because indigestible fiber is considered to be carbohydrate but being indigestible has no calories. Non-fiber carbohydrates are considered to have 4 calories per gram. So in the example of the corn, there are 12 grams of fiber. This leaves 111 grams of carbs times 4 calories = 444 calories from carbohydrates. There are 16 grams of protein in the 166 gram quantity and protein is also counted @4 calories per gram, so 4x16= 64 calories from protein. Fat is considered to have 9 calories per gram and the cup of corn contains 8 grams of fat, so 8x9=72 calories from fat.
One cup of chicken salad spread contains 416 calories. It also has 28 grams of fat, 15 grams of carbohydrate, and 24 grams of protein.
Peanut butter is a blend of protein, fat and starch or carbohydrates. For example, if you had 2 tablespoons of peanut butter, you would get 6 grams or 24 calories worth of starch/carbohydrate; 8 grams or 32 calories worth of protein; and 16 grams or 144 calories worth of fat.
One cup of raw brown rice is probably about 100 grams. It should be around 331 calories. Three grams of fat, 60 grams of carbohydrate, eight grams of protein.
Every gram of carbohydrate has 4 calories, so 20 grams of carbohydrates would be 80 calories. But you also have to take into account the amount of protein and fat grams in the food, as well. Protein has the same amount of calories as carbohydrates (4 calories per gram) and fat has 9 calories per gram.
How many calories are in a food which has 10 grams of protein, 4 grams of fat, and 20 grams of carbohydrate
There are 180 calories in 45 grams of carbohydrates.
