Lets have some fun, everyone try to come up with at least one theory.

So i've been doing a bit of research on non-oral taste receptors. i found some interesting bits of info! I guess this topic isn't super important but gosh i found it incredibly interesting!!!!

First off, apparently we have taste receptors in our testicles (if said "we" have any) and the Anus. These taste receptors can only detect Umami. for some reason when scientists removed the taste receptors from the testicles of rats they became completely infertile. As for the anus i found a tough time searching for what reasons we have them for. this is why i proposed the idea of hypothesizing reasons for this.

So then there's the Lung taste receptors, they detect bitter. At first i thought "toxins, it probably detects toxins in the air! of course! The taste buds in your tongue are designed to detect bitter because alot of poisons are bitter". At first the scientists who discovered this thought the same exact thing, but they later found out that bitter substances open up the lungs alot more than the standards asthma and OPCD meds (this promted me to thinking about vaporizing bitter herbs like Calea Zachatechichi or perhaps something else).

Your Pancreas can detect sweet flavors (particularly fructose) and doing so may cause your pancreas to increase insulin production (which could be fairly bad for diabetes. Also btw, your tongue can't tell the difference between sugar and artificial sweeteners (i've heard stevia is an exception) and so your tongue will tell your brain to tell the pancreas to respond by increasing insulin production; again bad for diabetes).

Your Intestines don't detect taste but do turn on an area of the brain involved in feelings of satiation or hunger.

Finally there's your brain. I didn't find much except for some info on how your brain recieves signals from the tastebuds in your mouth. i wish i could find more info on why and how we have taste receptors in our brain. i might just be confused and it might be that the taste receptors in the brain were what they were talking about.

anyways, hope this brought a smile to some peoples faces i know the research definitely intrigued myself!

This is interesting I have to disagree with one point though (based on my own experience): my mouth can detect the difference between sugar and artificial sweeteners. Sucralose is the only exception because it tastes exactly like sugar, but I can taste the difference between sugar and sweeteners. I think I can even taste the difference between aspartame and other artificial sweeteners! It's not just the after taste, the flavour profile is completely different. Sugar doesn't just taste sweet, sugar tastes like sugar.

There must be some trace amounts of other flavours/metals/impurities in sugar and artificial sweeteners that make them taste different. They do taste different.

Did it say if only men have taste receptors in their anuses or if women do too? that sounds interesting to say the least!

ohh i meant that the body reacts the same way to artificial sugars because the body (not so much the tongue, the tongue can definitely differentiate the taste and texture of different sweeteners and sugars) but the body itself should be like "hey i'm recieving sugar. i should probably start a biological process to prepare for it's new presence".

The title made me giggle
