Be warned, liars: Researchers in Germany say they have identified a reliable biomarker for coffee consumption that can verify whether or not people have recently drunk coffee.
A new study has found that the odour and taste from garlic or coffee can be found in breast milk, while flavours from fish oil or nursing tea weren t traced.
A study has found that the taste and odour of active substances from garlic or coffee partly enter the mother s milk as an odour active metabolic product, while flavours from fish oil or nursing tea were of little to no significance.
Researchers found that when mothers eat a curry dish containing piperine - a chemical responsible for the pungency in pepper - it soon becomes present in their breastmilk.
Pepper-containing foods can transfer into the mother's milk contributing to an increased tolerance at a later age, say researchers, who outline how dietary constituents are transferred from mother to baby.
