The human stomach is a J-shaped hollow muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.
The average human stomach can handle between one and one-and-a-half litres of food before getting the urge to throw it back up, but can stretch to accommodate four times that much before a rupture occurs.
Food is undoubtedly needed by the body to carry out various activities, (simple or complex) within the body, yet too much of it could be harmful too.
Normally, there are regulated amounts of food classes( protein, fat, carbohydrates, e.t.c) in our food supplements, however, when we eat a meal that’s high in fat, sugar and carbohydrates, the parasympathetic nervous system tells our body to slow down and focus on digesting the food, causing you or me to feel lethargic.
As the food is digested, cells in the pancreas produce the hormone insulin, which in turn leads to an increase in melatonin and serotonin, hormones that makes you feel drowsy as well as happy. You may also struggle to keep your eyes open, thanks to a spike in glucose levels from the food you’ve eaten.
This can interfere with the neurons in the brain that normally produce the orexin proteins responsible for keeping you awake and alert, hence alertness and wakefulness is compromised.
Our fat cells produce the hormone leptin, which binds with receptors in the brain to tell us that we're no longer hungry. But, eating more than your body needs causes your body to produce more of this hormone, as leptin levels are directly related to the amount of body fat a person has.
In such cases, people may build up a resistance to leptin, which disrupts the brain’s ability to recognise when you’re full, leading you to overeat and put on weight. And I'm sure you really dont want to put on some weight right?
Expecially you! (smiles) I caught you right there!
Save yourself from overweight! Inactivity! and even Diabetes Mellitus, e.t.c
Eat considerably! and may the Lord continually probide for us too! Amen!
