Background

Estimated Average Requirement (EAR): The average daily nutrient intake level that
is estimated to meet the requirements of half of the healthy individuals in a particular life
stage and gender group.

Recommended Dietary Allowance (RDA): The average daily dietary nutrient intake
level that is sufficient to meet the nutrient requirements of nearly all (97-98 percent)
healthy individuals in a particular life stage and gender group.

Classification of amino acids.

Indispensable	Dispensable	Conditionally Indispensable	Precursors of Conditionally Indispensable
Conditionally indispensable is defined as requiring a dietary source when endogenous synthesis cannot meet metabolic need. Although histidine is considered indispensable, unlike the other eight indispensable amino acids, it does not fulfill the criteria of reducing protein deposition and inducing negative nitrogen balance promptly upon removal from the diet.
Histidine	Alanine	Arginine	Glutamine/glutamate, aspartate
Isoleucine	Aspartic acid	Cysteine	Methionine, serine
Leucine	Asparagine	Glutamine	Glutamic acid/ammonia
Lysine	Glutamic acid	Glycine	Serine, choline
Methionine	Serine	Proline	Glutamate
Phenylalanine		Tyrosine	Phenylalanine
Threonine
Tryptophan
Valine

Estimated 'Calorie' Calculators

Several of these calculators may be particularly useful for dieters. Just about every single MAJOR calorie/ energy equation that has been released over the last 90 years is included below. Each calculator has a customized printout option for easy analysis. Recommendation: Try each calculator - print out the results - then compare!
Basal Metabolic Rate (BMR) Overview.

Harris-Benedict Equation: Estimation of total calories needed. MOST widely used equation for calculating basal metabolic rate and total calories.
Revised Harris-Benedict Equation:The original Harris Benedict equation was revised in 1984. This updated equation can be used to calculate the basal metabolic rate and total calories.
RESTING Metabolic Rate (RMR): Resting Metabolic Rate Calc - This equation can be used to calculate the RESTING metabolic rate and total calories. Mifflin-St Jeor equation.
Schofield equation (BMR) : This equation was part of the previous government guidelines to formulate RDA's and can be used to calculate the basal metabolic rate and total calories needed.
Institute of Medicine Equation- LATEST EQUATION: IOM Equation-Estimated Energy Requirement (EER) Estimation of total calories needed. This equation is behind the 2005 Dietary Guidelines for Americans and the new food pyramid, MyPyramid.

Body Weight Calculators

Adjusted Body Weight Calculator and Ideal Body Weight Calculator
Body Mass Index Calculator - BMI - Determines if your weight is in proportion to your height based on Federal guidelines released by the National Heart, Lung, and Blood Institute. The BMI is helpful in determining health risks and appropriate interventions.
Dieting Calculator - This calculator provides several useful outputs including the calculated 'Body Mass Index' or BMI. It will also estimate your 'Basal Metabolic Rate' or BMR. Also included is an estimate of your 'Total Energy Expenditure' or TEE which indicates the number of calories needed per day to maintain your current weight.

Fiber Calculators

Soluble Fiber Calculator - Cholesterol lowering - Soluble fiber: viscous fiber that delays gastric emptying and can result in an extended feeling of fullness. Need at least 7 grams per day to maximize cholesterol lowering benefits.
TOTAL Fiber Calculator - Great tool for dieters! - Insoluble fiber: does not dissolve in water and is not affected by digestive enzymes in the gastrointestinal tract. Insoluble fiber provides bulk which eases defecation.
Daily Fiber Requirements based on AGE

Protein

Protein requirements (daily) - calculate the amount of protein that should be consumed daily based on the latest guidelines.
