Nutripoints [9] is a food-rating system which places foods on a numerical scale based on their overall nutritional value. The method is based on an analysis of 26 positive factors (such as vitamins, minerals, protein and fiber) and negative factors (such as cholesterol, saturated fat, sugar and sodium) relative to calories.
Based on the total score, a label ranging from A (best) to E (worst) is assigned. Nutritional contents negatively (N) affecting the Nutri-Score are: high energy density per 100 g or per 100 ml, high sugar content, high content of saturated fatty acids, high salt content. Nutritional contents positively (P) affecting the Nutri-Score are:
The fat content of milk is the proportion of milk, by weight, [1]: 266 made up by butterfat. The fat content, particularly of cow's milk, is modified to make a variety of products. The fat content of milk is usually stated on the container, and the color of the label or milk bottle top varied to enable quick recognition.
The rate at which the consumer encounters food items per unit of food density is called the attack rate, a. The average time spent on processing a food item is called the handling time, h . Similar equations are the Monod equation for the growth of microorganisms and the Michaelis–Menten equation for the rate of enzymatic reactions.
The British Heart Foundation also advises people to cut down on saturated fat, and to read labels on the food they buy. [ 96 ] [ 97 ] The British Nutrition Foundation have said that based on the totality of available evidence the saturated fatty acids should make up no more than 10% of total dietary energy.
Based on the work of Atwater, it became common practice to calculate energy content of foods using 4 kcal/g for carbohydrates and proteins and 9 kcal/g for lipids. [2] The system was later improved by Annabel Merrill and Bernice Watt of the USDA , who derived a system whereby specific calorie conversion factors for different foods were proposed ...
Whereas glycemic index is defined for each type of food, glycemic load can be calculated for any size serving of a food, an entire meal, or an entire day's meals. [citation needed] Glycemic load of a 100 g serving of food can be calculated as its carbohydrate content measured in grams (g), multiplied by the food's GI, and divided by 100.
The Insulin Index is not the same as a glycemic index (GI), which is based exclusively on the digestible carbohydrate content of food, and represents a comparison of foods in amounts with equal digestible carbohydrate content (typically 50 g). The insulin index compares foods in amounts with equal overall caloric content (240 kcal or 1000 kJ).
