Carbohydrates & Fibre Introduction to carbohydrates

Let's review PROTEINS from last lesson.....

You have 5 minutes to answer the discussion question on Canvas relating to proteins and what you learnt last lesson. Go!

DID YOU KNOW: Carbohydrates can be found in fruits, vegetables, grains, breads, and sugar-foods.


VIDEO & QUESTIONS: Watch the following Ted Ed Video on Carbohydrates and fill out the accompanying questions in your workbooklet.

Let's get crafty.....

ACTIVITY: Using page 37 of your text and the craft materials behind the bar, construct the following structures onto poster paper. Make sure to use colours and to label each structure: glucose, fructose, galactose, sucrose, lactose, maltose, oligosaccharide and a polysaccharide.

Draw these structures in your workbooklet. Be sure to use colour and labels.

HOMEWORK #2: Complete Homework #2 on page 8 of your booklet, as well as making sure that all the content from pages 1-8 is completed.

DID YOU KNOW: Some carbohydrate based foods break down quickly and are absorbed into your blood faster than others. Can you think of any that give you a quick buzz?
Get ready to cook......
We will be cooking Jacket Potatoes with Coleslaw which are full of starchy carbohydrate as well as complex carbohydrates
DID YOU KNOW: Juicing is a process that extracts most of the insoluble fibre out of a fruit or vegetables while retaining the soluble fibre. Is this a good thing?

READING: Read page 38 of the text on Glycemic Index

BOARD NOTES: We know that all carbohydrates function as relatively quick energy sources. However, simple carbohydrates cause bursts of energy much more quickly than complex carbohydrates, because of the quicker rate at which they are digested and absorbed.

The glycemic index (GI) rates carbohydrates on how quickly they are digested, absorbed and metabolised and raise the glucose level in the blood, over a two hour period.

Carbohydrates are given a score out of 100; the lower the score the lower the glycemic index. The foods you consume should have a low GI for sustained energy release. Carbohydrates that are rapidly digested, absorbed or metabolised, such as white bread, result in a rapid increase in blood glucose levels and have a high glycemic index of 70 or above.

ACTIVITY: Answer Question 1 & 2 on page 9 of your workbooklet in relation to the below graph.

DID YOU KNOW: Fibre is a non-digestible, plant-derived carbohydrate that passes through the human digestive tract essentially intact and has little to no energy value.

HOMEWORK #3: Complete Activity 2.1 found on page 39 of your text book and page 11 of your workbooklet.

DID YOU KNOW: In general, coarse, grainy breads with higher amounts of fibre have a lower GI value than white breads.
