I want to avoid liverstress.
I use a lot of pepper to flavour my meat.
There are articles claiming that pepper is hard
On the liver and spicy food in general.
I hadn't seen any literature corroborating this statement. I had an idea of how one might extrapolate this position: nightshade family.
Plant Consumption and Liver Health
"Patients with liver disease are advised to avoid nightshade plants which are the common name for the Solanaceae family that consists of more than 2800 plants. Well-known nightshades include eggplant, ground cherries (any of the genus Physalis), mandrake (Mandragora officinarum),
peppers, pimentos (Capsicum annuum), potatoes, tobacco, tomatillos (Physalis ixocarpa), and tomatoes. Animal study of several nightshades resulted in the conclusion that the plants are hepatotoxic showing amyloidosis and moderate necrosis in liver [70]. Another nightshade plant (Solanum cernuum Vellozo) was also involved in hepatic toxicity when it was used in high dose and significant increase in the activities of alanine aminotransferase and aspartate aminotransferase was observed [71]."
While there are members of the nightshade family which do cause liver stress, I'm not seeing peppers explicity indicated anywhere. However, if discussing peppercorns, that is a different plant family altogether.
If anyone has found better data, I'd like to see it.
