The Pinetree Riddle: Have You Experienced It?

AI Thread Summary
The discussion centers around an article highlighting a phenomenon where some individuals experience a bitter taste in all foods, particularly in wine, tea, and coffee, two days after consuming pine tree seeds. This alteration in taste perception lasts for about five days before normalizing. The cause remains unclear, but it may involve a chemical in the seeds affecting bitter taste receptors. Participants noted they had not experienced this effect, suggesting it might depend on the species of pine nuts consumed, with some referencing the Pinon pine (Pinus edulis). The conversation also touches on the Synsepalum dulcificum fruit, known for temporarily altering taste perceptions by making sour foods taste sweet, and its historical context regarding FDA regulations that prevented its commercial use as a sugar substitute.

I read a remarkable article in the newspaper a few days ago, I was wondering if anyone has ever experienced such a thing? It is at least something to pay attention to.

Apparently quite a few people experience an alteration in their perception of taste, two days after eating pine tree seeds. All of a sudden everything what they eat will taste bitter, especially wine, tea and coffee become undrinkable. After five days the bitter tastes disappear and the perception is normalized.

The delayed effect has been hard to explain, there is a fruit known that can change taste perception: the Synsepalum dulcificum. It makes sour food taste sweet, but the effect only lasts a couple of hours.

Is there an English version? :-p

I've never noticed any effect of eating pine nuts on taste of other things, and I ate a lot of them for a while (bought a big package and added them to everything). I'd definitely remember if my coffee didn't taste good anymore.

Why, it's just Dutch :biggrin:

Sorry, the online website translators are terrible so won't be of any use. The article basically describes what I summarized. There might be a chemical in the pine tree nuts that changes the sensitivity of your bitter-sensing taste buds. They have no clue where it comes from, there doesn't seem a specific source.

I'd definitely remember if my coffee didn't taste good anymore.
haha, Yeah, I haven't noticed the effect either.
 
Well that makes 3 of us who haven't noticed the effects of altered taste after eating pine nuts {seeds}. Maybe its a different species, the pine nuts we eat here come from the Pinon pine{Pinus edulis}.

Make that four of us, hypatia. I have had pretty generous helpings of pine nuts with salads and in trail mixes, and my coffee always tastes fine.

Perhaps that's effect of eating nuts of Pinus nonedulis?

Known in the central states of the US as the notapinenut... :rolleyes:
 
Here's something I remembered that is related to the main topic of this thread. This is a New York Times article on a west African fruit, Synsepalum dulcificum, that drastically alters the sense of taste of other foods for several hours.

Chemicals in the fruit are said to bind to the bitter and sour receptors on the tongue, blocking or modifying what is sensed.

This plant is thinking out of the box! It is a completely different response to create an incentive for animals to eat fruit, from "be tasty," to "make everything else tasty."

Yes, I mentioned it in my first post. I've heard the rumor that the US food industry wanted to use it as an ingredient, but that it got banned.

Indeed, in the article it says: "During the 1970s, a ruling by the Food and Drug Administration dashed hopes that an extract of miraculin could be sold as a sugar substitute. In the absence of any plausible commercial application, the miracle fruit has acquired a bit of a cult following".
