What Is Bioavailability And Precisely How Does It Operate?
In our current realm, we're seeing more and more phrases starting with 'bio' joining our everyday vocabulary. Words like 'biodegradable' and 'biofuel' are two such words that we now frequently find in modern speech which are in all likelihood as a result of our increased preoccupation with conserving our planet. This is not to say that words such as this are newly invented as lots of them have been in existence for many years. On the other hand, there are terms out there such as 'bioavailable' and 'bioavailability' for example which aren't regularly used a lot in daily language. Naturally, if you have trained in pharmacology then these terms will most likely be really recognizable to you. You'll also very likely understand what the words make reference to and how they're used in pharmacological circumstances. That being said, what we are concerned with here is looking at the concept of bioavailability from a wellness perspective in terminology that a layperson can understand. There are a number of ways in which a substance can enter the human body. It could go in via the nose by inhalation, through the epidermis via flesh contact, through being injected using an IV or needle or by being ingested. With regards to the food we eat, or more precisely, at the level that swallowed substances are absorbed by the body, these substances are taken up in varying levels and amounts. At this point, we aren't speaking here about the ability of the various internal organs and tissue to absorb compounds but instead how favorable a distinct substance is to becoming assimilated. As we pointed out in the previous paragraph, the compounds which in this case are nutritional substances have differing uptake levels and rates of assimilation. This rate and level of assimilation is known as 'bioavailability' (BA) and there are varying degrees of it hinging on how bioavailable a substance is. To explain this principle a little bit better, let's use the process of digestion in the body of a human to illustrate. Nutrititional substances that are eaten in the form of food items all take the same route through your body's digestive system. To begin with, the foodstuff is broken down in the oral cavity by saliva as well as chewing and then by digestion juices in the tummy once it has been swallowed. These processes allow the nutritional compounds to be discharged so that they are able to carry on their path into the bloodstream and get taken up by the body's tissues and organs. Some nutritional compounds are readily assimilated by the body's organs and tissues and, consequently, are considered to be highly bioavailable whereas others are much more difficult to assimilate. What is more, the rate and speed of assimilation can be affected by factors like whether the substance is soluble in water or oil, for instance. Even a person's eating habits can play a role in absorption level. Take the dangerous substance lead, for instance. Even though it is dangerous to the body and is not something we want our bodies to take in in any way, shape or form, we could be susceptible to enhanced assimilation of lead if we have insufficient calcium and iron in our food intake.
