Today's topic: Healthy Digestion: The Key to a Healthy You

By Joe Singleton


The proper digestion of the foods you consume and the beverages you drink demands the integrated cooperation of vastly complex chemical and physical machinery. Only when every component is operating efficiently can your meals be converted into your great health. It's incredible how integral proper digestive function is to health general. Optimizing digestive function impacts the health of a lot of other systems throughout the physique. We all know the saying, "You are what you consume!" This is indeed true as digestive health is the key to general wellness.



As one thinks about this link, it makes sense. Right after all, the digestive tract, stretching from the mouth towards the rectum, is a main website of contact with the outside world. Our meals, toxins, microbes and other environmental substances all enter our system via the digestive tract. This system plays a vital function as an immune barrier in two main methods. Firstly, it acts as a structural barrier merely by keeping bad issues out and great issues in, only allowing issues to pass via for specific reasons. Second, it is a main component of our immune system and the initial line of defense for our bodies. Major immune structures and immunoglobulins reside within the digestive tract or are manufactured there. These elements play an important function in sustaining our general immune defenses. Therefore the dual function played by the digestive tract, by acting as a physical barrier and an immunological barrier, is vital to our health. Given this crucial function, it is simple to see how the health of the digestive tract can impact a lot of other areas throughout the physique.

Now that we comprehend the importance of digestive health, let's look at how we can best maintain it. To be able to do that, we have to explore the function of the various components of this system. Digestion literally begins with the sight and smell of meals. These senses initiate the production of enzymes within the mouth that prepare for the arrival of meals and to start the procedure of breaking foods down. Of course, chewing is a critically important step as this permits the salivary enzymes to start acting on the meals. From here, the meals moves down via the esophagus and in to the stomach.

Stomach

The stomach mixes meals with the acid and enzymes it adds to what you've eaten; the acid partially dissolves big meals particles into a lot smaller ones and the enzymes start the digestion of those smaller fat and protein particles. Along with stomach acid, pepsin plays an important function by breaking down proteins into smaller particles recognized as peptides.

Small Intestine

The little intestine is exactly where most food digestion and nutrient absorption occur. Most food digestion happens within the upper little intestine and most from the absorption from the individual vitamins happens in its lower regions. Anything remaining right after traveling down the length from the little intestine goes into the large intestine for a various kind of processing prior to being expelled within the stool.

Pancreatic Enzymes

Meals leaving the stomach stimulates the pancreas to send a package of digestive enzymes towards the little intestine where they join the bile from the gallbladder. Together these enzymes can digest just about something we're likely to consume except fiber. They serve to further break down fats, carbohydrates and proteins into their components and vitamins for assimilation. But there's a catch - all of the digesting compounds sent towards the little intestine could digest our pancreas and gall bladder, so they're initially sent in inactive forms. Once they arrive, the little intestine releases a "master enzyme" that activates all of the other people and will get digestion truly rolling.

Bicarbonate

There's another catch - all that stomach acid could deactivate the enzymes. To prevent this, the pancreas sends together with its enzymes some bicarbonate. This neutralizes the excess acidity and serves to protect the enzymes and lining of the little intestine from stomach acids. The little intestine itself does its part by covering its inner lining with a layer of bicarbonate-rich mucus.

Water

In order for that digestive procedure to perform smoothly, h2o is really a necessary cofactor. Copious quantities of h2o are needed to keep everything dissolved. This h2o comes in the beverages we drink during meals and snacks and from your blood. Several cups of h2o are moved from your circulation into your digestive tract with every meal or snack. Although in younger people the hydration of the circulation is maintained by the entry of h2o from other parts of the physique, studies published lately in the American Journal of Clinical Nutrition and the Journal of Applied Physiology discovered that in older adults the physique surrenders less of its total h2o to the circulation, increasing the risk for bouts of dehydration after meals

The Colon

Your large intestine, or colon, is required to perform one main and essential task above all others - retrieve back into the physique the h2o that has been added to your food by your saliva and digestive secretions. This h2o was taken out of your bloodstream (about 1 to 2 cups per meal) and added to the material in your alimentary tract (the "digesta") to assist your physique digest food and absorb its vitamins relatively rapidly and, for that most part, very efficiently. Nevertheless, if that h2o is merely lost via your stool you would dehydrate extremely rapidly a few hours right after every meal - certainly not a healthy outcome!

The cells lining the colon are responsible for recapturing the water and restoring it to your blood. Normally they're very efficient. And, like anybody else, these tough workers have to be fed. Here's something you most likely don't know: Unlike just about every other cell in our physique, the cells lining our colon aren't fed via the bloodstream. They get their nutrition directly from whatever will get to them from the little intestine - the leftovers of the digestive procedure. If they're undernourished, they can't operate successfully. This leads to abnormal stools and inefficient digestive function.

Lately, the colon has also been recognized as being a main immune organ. It contributes to general immunity by functioning because the reservoir for healthy (and unfortunately, unhealthy) bacteria and yeast. Numerous studies shine light on the positive well being advantages associated with healthy gut ecology and adequate numbers and strains of probiotic organisms. Likewise, the chronic presence of unhealthy bacteria and yeast lead to unhealthy digestive function and detrimental effects on immune functioning. Maintaining healthy gut ecology by supporting colon well being is essential for our well-being.

Our colon depends on two main elements to keep it healthy: A healthy stability of probiotic organisms, because the intestines, particularly the colon, are where the majority of these beneficial organisms reside, and Sufficient quantities of fiber within the diet. This should be within the form of both soluble and insoluble fibers.

Changes with Age

Research suggests that this entire procedure might work much less and much less nicely as we get older. And of course there's no justice - this age effect doesn't mean we are able to consume much more with out gaining as a lot weight; it means that as we age the stability between what we consume, what we absorb and what our physique needs grows increasingly out of whack. Therefore, with age it becomes much more essential to ensure that our digestive tracts function at an optimal level. This frequently requires nutritional support.
