The Small Intestine
After the mush passes through the pylorus it makes it to the small intestine. The small intestine is made up of 3 parts: The duodenum, the jejunum, and the ileum. The duodenum is first and super complicated, it is where the bile and pancreatic enzymes meet the mush from the stomach. This mixture is now called chyme. The acid denatured protein is chopped up by the pancreatic enzymes to make amino acids which can now be transported across the jejunum and ileum lining which is made up of villi. Fat, the remaining carbs, and vitamins and minerals are all absorbed in the small intestine as well. Digestive enzymes are an available supplement to help with digestion. Papain, bromelain, and lactase are examples. For instance if someone is lactose intolerant then they don’t make the enzyme lactase. Lactase cleaves lactose into glucose and galactose. When this digestive enzyme is taken as a supplement the person is better equipped to digest dairy.
Villi are like little fingers with lots of blood supply that stick out from the wall of the intestine. Gluten, found in wheat based foods, damages the villi and thus indirectly impedes absorption of many nutrients. People will argue this. Those people love bread and other garbage and are in denial. If your part cow maybe you can digest it, but no one needs it so just cut that junk out of your diet.
When nutrients are absorbed through your intestines it passes into the bloodstream of the GI system which all gets routed to your liver by the portal vein. The liver attacks any drugs and tries to clear them since they are seen as toxins.
If you take supplements, and if you’re reading this you probably do, then pay attention: if your taking those supplements on a full stomach or with food their absorption is altered by the absorption of the food. They can chemically bond with the food or be modified by the stomach acid or food. Thats why there are 4 times to take your supplements: First thing in the morning, when your stomach is empty, pre workout, post workout, and right before bed. I have designed products with the right amount of the best ingredients for each of those times. If you want to take supplements on a full stomach use a sublingual delivery. This bypasses all digestion and the portal system and thus the liver. This drives bioavailability sky high. Unless you need the liver to convert a drug or supplement to an active compound you’re always better off with sublingual delivery.
This is really little more than a way for your body to absorb water and electrolytes from your feces. Any chyme that makes it this far wasn’t digested and absorbed. If your feces smells like something you ate then guess what, you didn’t absorb it. Either eat less at a time or don’t eat it at all. Once chyme makes it to your colon bacteria start digesting it. This produces gas and that is where bloating and farting comes from. Another sign you ate something you shouldn’t. Probiotics are not another name for digestive enzymes, despite popular belief. They are live cultured bacteria which live in your colon and have a symbiotic relationship with you. These bacteria eat the fiber we can’t digest and often dairy and gluten…and all the food you couldn’t absorb because your villi were to inflamed by the gluten you had to have. If you’re eating only foods your body can digest and absorb then you should be as regular as a dog. 15 g Psyllium Fiber before bed with 30 oz of water should ensure this. Most commercial fiber products have sugar or say they don’t and lie. You want to order straight Psyllium fiber.
You’re probably thinking; What about chylomicron absorption? The immune system? GIP? IgA? Food allergies? Nutritional absorption post gastric bypass? Pernicious anemia? Sorry charlie, All those sub components are to complicated to add to one article. It would be a whole textbook if i went in depth!
