Prolly one for Stromba....

I can get a protin shake thats low carb hihg protien, so contains 10g of protien per can, and costs £1 a can

I can go to my locl co-op and buy a 200g bag of penuts, each 100g provides me with 29g of protien, each bag is 59p

So i can eat half a bag of peanuts a day and get 29g of protien a day extra costing me £0.30, or i can drink 3 protien shakes a day and get 30g of protien, at a cost of £3 a day.

Is there any reason i shoudl't go for the cheap option over the more expensive one, ie peanuts?
