Potatoes, tomatoes, peppers and aubergines. These are not just a random list of food, they are all part of the same group, the nightshades, along with the spices, cayenne and paprika.
First thoughts when it comes to nightshades may well be the age old poison, 'deadly nightshade' but whilst this food group is not deadly, it might surprise you to know that in some individuals it can cause problems.
Nightshade foods contain alkaloids, particularly steroid alkaloids. For individuals who are sensitive to these compounds, common symptoms can manifest themselves as joint or muscle pain/stiffness, skin rashes or digestive discomfort.
I have known for some time that I am intolerant to nightshades and should avoid eating these foods. But I have one major problem, I love food. I love all sorts of food, I'm not fussy and up until recently I was eating nightshade foods without even realising that they were making me ill.
