Dr. Frank has over 25 years’ experience as a Nutrient Analysis Expert. She has worked with the media, cookbook publishers, recipe bloggers & websites. Dr. Frank wrote “From As Purchased to Edible Portion,” as an essential tool for anyone providing nutrient analysis.

Purchasing nutrient analysis software and learning how to use the program is only useful if you have the knowledge to convert “as purchased” ingredients to the “edible portion.” This book describes how to read a recipe and enter the correct ingredients and amounts, in order to provide an accurate nutrient analysis.

Nutrition Analysis is part of our everyday life. We have grown accustomed to nutrition information being readily available. But what if a recipe has no nutrition information or even worse the information is wrong?

People with medical conditions might not try the recipe. There are millions of people who have special dietary needs, such as low calorie, carbohydrate controlled, high protein, low protein, low carbohydrate, low fat, low cholesterol, low sodium, high fiber, gluten free, lactose free, peanut allergies, and these are just a few of the diets available.

Many people believe if they just buy a nutrient analysis program, they can provide an accurate nutrition analysis for a recipe. This is far from the truth.

Recipes are usually written based on what the consumer needs to purchase. The individual analyzing the recipe must evaluate the recipe based on the actual food ready to eat (unless the food is meant to be eaten whole.)

A nutrient analysis program cannot cook or prepare meals. A person must have skills in Food Science, Culinary Nutrition, Cooking and Preparation Techniques, Purchasing Guides, Yield Factors, and Nutrient Analysis Software.

An essential tool for analysis is the food conversion and equivalent tables. These databases provide information on AP (as purchased), EP (edible portion), waste, marinating, straining, percentage of bones; difference between a raw or cooked weight; comparison of weight versus volume measures. Many nutrient analysis software programs do not provide this information for all items; therefore it must be calculated manually or estimated.

Most Americans believe one cup is equal to eight ounces; and they would be right if we were referring to a liquid. In selecting the correct measure of a food, it is critical to know whether the food is measured by weight or by volume. Weight measures include grams, ounces, and pounds. Volume measures are listed as teaspoons, tablespoons, fluid ounces, cups, pints, quarts, and gallons.
