Lecture: March 30, 2011

On Monday Dr. Hartley will be gone and Dr. Jones will be teaching class. Be nice to Dr. Jones!

Today we talked about talked about Ch. 45 which covers Nutrition, Digestion and Absorption.

One of the topics that came up was Diabetes. Here is some information on the disease:
Diabetes is a lifelong disease that arises when the body cannot produce or use insulin resulting in high blood glucose levels. Insulin is a hormone that takes glucose from the blood into the cells and is needed to convert sugar and starches into energy.
Type 1 Diabetes or Juvenile Diabetes occurs in children and young adults. Their bodies don’t make insulin or don’t know how to use it. People with Type 1 diabetes are put on Insulin therapy. Only 5% of people with diabetes have type 1.

Type 2 diabetes is the most common form of diabetes that affects millions of people. In type 2 diabetes the person either does not produce enough insulin or the body ignores the insulin being produced. People with type 2 diabetes have to ensure they are within adequate glucose levels to avoid any complications with glucose building up in the blood.
Gestational Diabetes is when an expecting mother develops diabetes after the 28th week of pregnancy. Often times gestational diabetes disappears after the baby is born.

Another question that came up in class was if it was better to add salt while cooking or after cooking. Here is what I found:
The longer food is cooked the more flavor is masked. Adding salt while you are cooking is not as healthy as adding it after because the salt being added while cooking loses flavor and often people add more salt to maintain that flavor. It is healthier to simply add salt after the cooking process is complete. Less salt is being added to the food but the flavor will remain the same. If salt should be added to a recipe try adding it last to reduce overall salt input.

The next question that came about was why we weigh less in the morning that at night?
We weigh less in the morning because our bodies have been asleep for the past 8 or so hours. While the body is sleeping it still respires however there is no energy intake. So essentially your body is burning more energy that it’s getting. Also while you respire you lose water and CO2 through respiration. These gases have mass which contributes to the overall loss of mass. ☺

Dr. Hartley was talking about an SNL video with Alec Baldwin that talked about the body systems. I couldn’t find it, but I’ll keep looking and post it if I do!
