What do you all think of these findings, particularly regarding the foods listed? Some of them are known to be heathy, such as: fish, beans, nuts, pulses, spinach and beets!
Also - What if you already have aggressive prostate cancer, then does eating the less lethal food, mentioned below, become less or non-impactful?
"The researchers found associations between more aggressive prostate cancer and three metabolites – phenylacetylglutamine, choline, and betaine."
"The researchers found that men with elevated phenylacetylglutamine in their blood serum at the start of the study were 2.5 times more likely to die of prostate cancer than those with the lowest levels. Men with increased choline or betaine had almost twice the risk of lethal prostate cancer as controls."
"Phenylacetylglutamine is produced when gut bacteria break down phenylalanine, an essential amino acid. Choline and betaine are in some foods, as well as being formed by gut bacteria.
Phenylalanine is in high protein foods, such as dairy, meat, poultry, soy, fish, beans, nuts, and diet sodas sweetened with aspartame. It is an essential part of many proteins and enzymes in the body and, when converted to tyrosine, is used to make the neurotransmitter dopamine.
CholineTrusted Source is found mainly in animal products, such as meat, fish, eggs, and dairy, although pulses, nuts, and seeds are sources for vegans. Foods high in betaineTrusted Source include shellfish, wheat, spinach, and beets.

Dr. Sharifi commented: “[Our findings] suggest that food intake has a complex interaction with gut bacteria to affect lethal prostate cancer risk.”
Some gut bacteria convert choline and betaine into trimethylamine and trimethylamine N-oxide (TMAO)Trusted Source, which a previous studyTrusted Source found may also increase the risk of cardiovascular and neurological disorders. This is the first study to show an association between precursors of TMAO and cancer.
“Betaine and choline are being converted into more toxic chemicals in some. This does not mean they are bad for everyone. It’s the diet-microbe interaction that leads to the cancer.”
