Sugar? Starch? Carb? What’s The Difference!

Sugar? Starch? Carb? What’s The Difference!

Last week we talked about forms of sugar (words ending -ose) and how they are different or alike. In many cases the sugars broke down to, in at least part, glucose. Glucose is used by your muscles to perform work. Sugars are SIMPLE carbohydrates. COMPLEX carbohydrates are what we call “starches”.

Why Do I CARE??

GLYCOGEN! Glycogen is why you care.

Glycogen is one of TWO forms of energy storage in the body:

1. Glycogen stored in muscle and the liver.

2. Triglycerides (i.e. FAT) stored in adipose tissue.

So, let’s get to the point…Your body can store 1-day’s worth of glycogen. The trick is, your body will use your “one day” stores of glycogen BEFORE relying on the stored energy in your fat cells. Meaning, you MUST exercise off your daily stores before you can mobilize the energy stored in the fat cells. Keep your energy/food intake in check!

Why Complex Carbohydrates Matter

All forms of sugar, and starch, break down into glucose. Starch is a COMPLEX CARB (i.e. 3-10 sugars linked in a long COMPLEX chain) vs sugar being a SIMPLE CARB.

Starch/complex carbs break down slower than simple carbs/sugar. Since complex carbs break down slower, we stay “full” longer. Complex carb examples include peas, beans, whole grains, and vegetables. Stick with complex carbs in your diet vs simple carbs for overall health!

Starch come in the forms of digestible and resistant starch. Digestible starch is quickly turned into fat if we don’t use it right away. Resistant starch doesn’t get digested in the small intestine like digestible starch, instead many types ferment in the large intestine and act like fiber! Resistant starches are not broken down into glucose in the stomach, so they have a lower calorie content, also improve insulin sensitivity/lower our blood sugar levels and keep us full longer (thanks to the slow digestion). Although there are various types of resistant starch, some examples are grains, seeds, legumes, potatoes and unrefined rice.

WAIT: White rice is “refined”, which means it’s been processed, and the fiber has been broken down making it a SIMPLE carb. Brown rice however is a whole grain – fiber intact – so it is a complex carb. Purchase whole grain rice!

Good Carbs vs. Bad Carbs??

Why are the terms “good carbs” and “bad carbs” floating out there? GOOD carbs can be considered those that not only contain energy/glucose (i.e. refined sugar) but also vitamins and minerals (i.e. vegetables – more bang for your your calorie-buck).

EXERCISE improves how our body moves sugar/glucose into our muscles, eventually causing you to require much less insulin than someone who is physically inactive.
