Food nutrition value

Reading and Understanding Food Nutrition Value

When you go to the supermarket to shop for food, odds are you noticed that there was a listing of nutrients and ingredients on the back of the food package and wondered exactly what the point of that was. It turns out that some time ago the United States government realized that people were eating improperly because they likely didn’t understand what exactly was in the food they were eating. Not knowing calories, fat contents and other nutrient values in food can lead to eating too much of a certain nutrient or other compound. This can lead to health problems down the road, which is why you have to understand food nutrition value.

What Food Nutrition Value Measures

Food nutrition value measures raw food nutrition, which is the amount of nutrients given to the body from a given serving of food. Nutritional value is measured in terms of a percentage, meaning how much of a mparticluar nutrient your body getws from eating one serving of a given food. For example a slie of meat might give 40% of a peson’s daily value for protein. The food nutrition value is based on a person’s daily calorie intake. Every nutrient except for water has a certain amount of calores per gram, and all these add up to a full day’s worth of calorie consumption. There are generally two listings on a food nutrition value – one for 2000 calories and one for 2500.

2000 calories per day is the average adult human intake, meaning that It takes into account base metabolic rate and a reasonable amount of extra activity. The more you exercise, the more calories will be necessary to keep the body running, because more muscle tissues use more calories. Generally, people who are more active require at least 2500 calories per day. Men require more than women on average as well.

The best way to make use of knowing food nutrition value on the packaging is to mentally calculate how much of that food you could eat to get your recommended daily allowance of the most abundant nutrient. For most people, they look at the fat content first, and this may or may not be the wisest. After all, there are other nutrients than fat. You should look at vitamin A and C content in fruit or vegetable products especially. As a rule, you should be able to eat three servings of a given food at least and still be wihin your allotment of nutrients and calories, and make sure there’s a balance between calories and nutrients.
