I did get a few odd looks eating blueberries on the tube this evening, but I was hungry and that's all I had with me ... plus eating blueberries is way healthier than eating a bag of crisps, just not that 'normal'!
For some reason I haven't been able to get enough of them this past fortnight, but fortunately both Tesco and M+S have offers on them at the moment, and theirs seem to be particularly tasty (despite not being in season right now).
Blueberries are great with breakfast, as a pudding, in a smoothie or just on their own as a snack. Admittedly carrying them around in your handbag isn't that practical (it could end in a big blue mess) but they're a great desk snack and also worth freezing at home for the days when your cupboards are bare.
The pigments in fruit and vegetables are what contain the different antioxidants - the amazing blue pigment in blueberries (eat enough and you'll have a black tongue like we used to get from eating black jacks!) is particularly cardio-protective. This is why it's important to eat a variety of different coloured fruit and veg to get the full range of antioxidants, each of which protect against different toxins and can help prevent different diseases.
So whilst they're taking my fancy, I'll keep on snacking on blueberries ... just maybe not on public transport!
