Biochemistry of thyroid production
Introduction There are two hormones in humans are triiodothyronine (T3) and thyroxine (T4) that are responsible for the effects of thyroid function however, there is a cascade of events that must occur beforehand to make their production possible moreover, the presence of specific molecules and nutrients must be sufficient to produce these hormones in the first place Both of these hormones are composed of tyrosine and iodine, however T3 contains three iodine molecules and T4 contains four. T4 is considered the inactive form of thyroid hormone, and T3 is the active form. That is, in the cell T3 is the necessary form of the hormone for thyroid activity. T4 is very easily converted into T3, as we will discuss in a moment. Through a series of signals through the hypothalamic pituitary axis (HPA), we somehow come out on the other side with T3 and T4 being secreted into the bloodstream by the thyroid gland. However, there are many prerequisites that must take place before any of that can ensue.

The biology of taste
Taste is a sensation that is triggered by the presence of specific molecules on the tongue. These molecules stimulate a cellular response within cells on the tongue. The result is the activation of specific nerves that send a signal to the brain and are interpreted. Humans have 5 tastes that we can distinguish, each having a specific receptor. Humans can detect sweet, salty, bitter, sour, and umami molecules on the tongue. Each of these taste sensations are activated by different molecules, and there are a multitude of molecules that stimulate a given taste sensation.

Is consuming milk or milk products making you fat?
Milk is the first thing that we taste after taking birth into this world. That first motherly touch, that first sip of divine milk, although we do not remember, our bodies do. But as we transition from infancy to childhood, many of us stop drinking milk. And then when we enter adulthood, most of us stop drinking it at all. The reason? That it makes us fat. But how much truth is there in this statement? Make a search on Google and you might get flooded with tons of supportive reasons from both sides. These conflicting opinions on the subject can make it hard to know what to believe.
