Study Notes

Definition of a Calorie

A Calorie is the amount of heat energy needed to raise the temperature of one liter of water by one degree Celsius.

Energy from Food

Carbohydrates provide 4 Calories per gram.
Fat (lipids) provide 9 Calories per gram.
Protein provides 4 Calories per gram.
Alcohol provides 7 Calories per gram, but is not a nutrient.

Calculating Calories from Food

Multiply the number of grams of a macronutrient by the number of Calories per gram.

Total Calories Calculation

Add the number of calories from fat, carbohydrates, and protein to determine the total number of calories in a food.

Percentage of Calories

Divide the number of calories from a specific macronutrient by the total number of calories, then multiply by 100 to get the percentage of calories from that macronutrient.

Food Choices

Factors influencing food choices include: availability, cost, convenience, emotional factors, social factors, cultural factors, advertising/marketing, habit, positive association, personal preference, values and beliefs, and health.

Canada’s Food Guide

Guides healthy eating for Canadians 2 years of age and above.
Uses nutrition research to provide advice on healthy food choices for overall well-being.
The 5 basic characteristics of a healthy diet are: adequacy, balance, calorie control, moderation, and variety.

Nutrient Density
