How the nutrition value of a product is decided?

Hello,

The Nutrition value of a product decided by a group of experts, by a special analysis for the basic three food groups; Carbohydrates, Fats and Protein then after that another special analysis should be for vitamins and minerals.

but nowadays new food analysis programme called ESHA usually used to analysis any type of food we as a dietitians use it to analysis any kind of food only by using this application.

best regards.

By the amount of nutrients (vitamins&minerals) in the product in relation to the macronutrients (proteins&fats&carbs)

which you can know from the nutrition label and the ingredients of the product.

for example: sugar is pure carbs without any nutrients so it's nutrition value is very low so there shoudn't be much of it in food.

while rice is also a source of carbs but it contains a good amount of vitamins, minerals and fibers which differs in different types of rice (white,brown,wild) so in general it has a good nutrition value 

the same goes for oils and protein powders although they may be good and healthy for you their nutrition value is lower than avocados,nuts & chicken breasts,red meat.

How to read the nutritional information for products Nutrition Facts

How do you know the amount of carbohydrates, calories, fats and proteins, the products and the food that you buy?

I will confine myself to the calories and carbohydrates account in this post. Following the same way, you can rest nutrients Account

The picture above, an example of a product will read nutritional information.

First start identifying the amount by which we calculate on the basis of

Note the sentence:

Serving size: 3 cookies

This means that the amount of the share, which we calculate on the basis of which is three pieces of biscuits. This means that all the numbers that we read, are present in all three pieces of the biscuits

We start in calories, the Calories, which always put them in the foreground as it more importantly, however, it is not so when supporters of the Atkins :)

There are 130 calories if, in all three pieces. If every piece: 130 divided by 3 = 43 calories

Carbohydrates 19 grams carbohydrate. But those who follow the Atkins program, it be removed from the calculation, the resulting fiber carbohydrates Dietary Fiber and the Sugar Alcohol, because the body is not absorbed into the blood, but her out, and thus will not affect

 The rate of the rise in sugar

If: 19 grams, 7 grams Delete them, leaving 12 grams, in all three pieces. This means that a single piece, in which 4 grams carbohydrates

Another example, in which the Serving size is not specified size and number:

Note here that the Serving size is 172 grams. Instead of the number (three pills in the previous example). In this case, all the numbers that read it are present in every 172 grams of this product. And therefore you should look for net product Net Weight weight, and assume that 400 grams in this example.

I remember, we assume net weight here, but when you want to be counted among your own viewing pleasure on products, look for him: "Net Weight net weight." No product is free from this number at all, but be found the task may be difficult at times, where you need to read between the lines, and to turn the product many times with your hands: /

If the number of calories Calories is 200 calories, 172 grams each. And as long as we may assume that the net weight of the product is 400 grams, the amount of full-calorie which is 400 divided by 172 = 2.32 * 200 = 465 calories

465 calories in the whole product. Thus as yourself how much consumed. That I ate a quarter in your meal, you consumed 465 divided by 4 = 116 calories

Number 36 grams carbohydrates, 172 grams each. But those who follow the Atkins program, we have to cancel the carbohydrates from fiber Dietary Fiber because the body is not absorbed into the blood, but give it, and therefore will not affect the rate of the rise in sugar

36 grams, delete them 11 grams, 25 grams left. If the number of net carbs influential in Atkins is 25 grams per 172 grams of product weight

Thus, the total number of net carbohydrates in the product is 25 * 2.32 = 58 grams

58 grams carbohydrates in the whole product. Also, how much of yourself you consumed. That I ate half of it in your meal, you consumed 58 divided by two = 29 grams
