Lesson 3.2 Macronutrients Flashcards
Name the macronutrients.
The bulk of what we need to function is referred to as macronutrients. These include proteins, carbohydrates, and fats.
Why is macro in macronutrients?
We call them macro because we need them in fairly large quantities to support normal functioning, and daily requirements are measured in grams.

Our ideas and understanding of what constitutes a healthy diet have changed drastically in the last few decades. Expert opinions vary widely regarding the ideal ratio of proteins, carbohydrates, and fats we should consume for the most balanced diet.

What are the benefits of complex carbohydrates?
Today, many people understand the importance of choosing more complex carbohydrates to sustain energy levels and of increasing fibre intake.
