Nutrtion and digestive system

Hello, how about we start with nutritional science?

Let me welcome you to my blog and let's talk a little about the digestive system.

Love you all.

1.1- Digestive Enzymes

Amylase / Leptase / Pepsin / Trypsin

Chymotrypsin / Carboxypeptidase

Elastase / Ribonuclease / Deoxyribonuclease

Cholese / Sucrase / Isomaltase / Phosphatease

1.2- Digestive Enzymes

Amylose: Converts amylose to maltose

Maltase: Converts maltose to glucose

Amylose: Converts amylopectin to dextrin

Isomaltase: Converts dextrin to glucose

Sucrase: Converts sucrase to glucose

and fructose

Lactase:  Lactose is converted into glucose

and galactose

2- Digestive System Hormones

Gastrin

Secretin

Cholecytokolin

2.1- Digestive System Hormones

Gastrin: Secreted from the stomach, its function is to stimulate the stomach to

secrete hydrochloric acid and begin the digestion of food.

Secretin: Stimulates the pancreas to secrete fluids to neutralize

the acidic food coming from the stomach.

The hormone is stimulated by stomach acid.

Cholecytokolin: Its secretion is stimulated by fats, which in turn stimulates

the pancreas to secrete digestive juices.

 2.2- Pancreatic Hormones

Insulin

Glucagon

Somatostatin

2.3 Insulin Hormone

Secreted by the pancreas

Its primary function is to facilitate the entry of glucose into cells

and lower blood sugar levels

2.4 Glucagon Hormone

A hormone that helps release glucose from the body

and prevents diabetic coma, which raises

blood sugar levels

2.5 Somatostatin Hormone

This hormone inhibits the action of intestinal hormones

Now that we've discussed the digestive system, let's talk a little about the most important element the intestines need to support the balance of vital processes.

3- Fiber

3.1- Soluble Fiber

This is fiber that dissolves in water and is digestible

and easily dispersed, such as pectin and hemicellulose.

 3.2 - Its Functions and Benefits for the Body:

Slows absorption / Lowers cholesterol /

Reduces bad fats / Slows gastric emptying /

Increases satiety.

3.3 - Sources of Soluble Fiber

Lentils, grains, and legumes

White oats and bran

Fruits and nuts

Cucumbers and carrots

3.4 - Insoluble Fiber

This includes cellulose, lignin, and some types of heme fiber.

Cellulose.

Found in vegetables and most grains.

Consuming it treats constipation and irritable bowel syndrome.

3.5 - Insoluble Fiber

Beneficial for gut health

Has a laxative effect on stool

Helps in the reverse movement of food

Slows down the passage of food through the intestines, thus promoting absorption.

 3.6 Constipation and Fiber

We recommend 6-20 grams of bran per day, which increases stool bulk and bowel frequency.

If this is ineffective, we administer a lactose laxative.

3.7 Irritable Bowel Syndrome (IBS) and Fiber

Fiber is used to treat IBS in some cases and helps alleviate abdominal pain.

We give 12-16 grams of bran per day to treat constipation associated with IBS.

3.8 Diabetes and Fiber

Fiber is considered an effective treatment for diabetes.

A diet rich in fiber helps lower blood sugar.

 3.9- Fiber and Colon Cancer

Fiber contributes to reducing the risk of colon cancer.

Increased fiber intake and fermentation reduce the secretion of toxins in the colon.

Fiber also helps food move faster and viscous, reducing its retention in the colon and the formation of toxins.

4- Let's talk a little about the glycemic index:

The glycemic index

is an index that shows how much a food raises blood sugar levels.

When we say that a food has a glycemic index of

30, we mean that eating 100 grams of this food raises blood sugar levels to 30.

 And now we conclude our article for today with Insulin Resistance

5.1- Insulin Resistance

Signs of Insulin Resistance

Blood pressure reading above 140/85

Cholesterol above 200

Low LDL cholesterol above 130

Glucose above 100

Triglycerides above 150

Low HDL cholesterol below 5

5.2- Causes of Insulin Resistance

Bacteria and toxins

Lack of sleep

Alternative sweeteners

High blood pressure

Unhealthy diet

With this, we conclude our article for today.

See you tomorrow with a new article in nutritional science.

Enjoy your time.

May God protect you.

Love you all.
