They say Guinness is good for you but would it be possible to live on the black stuff alone?
It’s true that a pint of Guinness contains a whole variety of nutrients including 2g protein, 7.5g carbohydrate, 1mg iron and all the B vitamins except B12. However, it also contains alcohol, and lots of it (well, 16.5g, to be precise). A glass of the black stuff contains approximately 99 calories and a pint contains around 198 calories, which is less than most beers.
Since Guinness does not contain vitamin C, B12 or calcium, you would actually need to drink 47 pints of stout along with 2 glasses of milk and a glass of orange juice to get all the nutrients you need on a daily basis. That being so, it’s not exactly what we would recommend as a balanced diet!
Excessive alcohol consumption leads to liver damage, prevents fat-soluble vitamins being stored in the liver and also impairs vitamin absorption.
