Calculating energy and nutritional values GapFill

A person's basal metabolic rate (BMR) is the amount of energy their body needs to perform basic life processes, such as  runningbreathingexercisingbody composition or heartbeat. It changes depending on age, sex or gender, height and weight, and is usually higher for men than for women as they tend to be larger.

PAL, or  physically assisted learningpalpable adrenal lesionsphysical activity levelpeer assisted learning, reflects the amount of energy needed by the body to perform other functions, such as working or exercising. It is used to estimate energy  expeditionexpectednessexcitementexpenditure over a 24-hour period and is expressed as a number.

All our energy comes from food.  20509055% should be derived from carbohydrates, with 45% from starches, lactose and fruit sugars and a maximum of 5% from free sugars. Fats should provide 35% and proteins should provide   1021550%. 1g of pure carbohydrate provides 3.75kcal. 1g of pure fat provides 9.0kcal. 1g of pure protein provides  4.06.754.55.0kcal.

Nutritional analysis helps to plan and modify recipes, meals and  dietsfood diarylabelsroutine so that they reflect the  nutritional statemalnutritionnutritional valuenutritional needs of an individual. Many tools, such as food tables, are useful when calculating the  nutrient profilenutrient sketchdietary fibrenutrient outline of a food product or a meal.

A nutrient profile is the amount of various macronutrients and micronutrients in food. It is important as many food products contain a mixture of various  chemicalssystemsnutrientsmolecules - for example milk is a mixture of water, proteins, fats and sugars - and identifying how much of each a product contains allows consumers to make informed choices.

Both the energy content and nutritional value of a meal or diet can be changed by choosing the ingredients, adjusting their amount or replacing them with  surrogatesbackupreservealternatives. Energy values can also be easily altered or lowered by controlling the portion size of a meal.

To adjust or develop recipes to meet current dietary guidelines, it may be necessary to lower the amount of fat, sugar or salt, or to increase the amount of  dietary fibremonosaccharidessaturated fatscholesterol.
