Now that we’ve learned about the different macromolecules our bodies need and use, let’s return to our the questions we asked at the beginning of the modules about healthy diets:
Think about It
- Is it even possible for a person to cut all carbs out of their diet?
- Is it actually healthy to remove an entire class of molecules from the diet?
- Fats and cholesterol are strictly bad—right?
It is, in fact, impossible to have a no carb or no fat diet. These molecules are in all cells and cells make up what we eat. More importantly though, each of these biological macromolecules has a very important role to play. If you cut too much fat from your diet, for example, it is possible for your fat stores to dip low enough that your hair will fall out!
Even the much maligned cholesterol is a requirement for a healthy body and lifestyle: without sufficient cholesterol, your body doesn’t make enough sex hormones (estrogen or testosterone depending on if you’re male or female). The trick is to make healthy choices overall without too much of any biological macromolecules—after all, there can certainly be too much of a good thing.
It is tempting to view different topics as completely separate, but in fact the ideas we cover in this course are often connected to one another. If you don’t retain the vocabulary from module to module, those connections can be missed. As you continue on, remember to come back and review the terms you’ve learned in order to increase your depth of knowledge.
