(The relevant bit is at the end:
Other food rich in potassium (and therefore in 40K) include potatoes, kidney beans, sunflower seeds, and nuts.[18][19] Brazil nuts in particular are not only rich in 40K but may also contain significant amounts of radium, which have been measured at up to 444 Bq/kg (12 nCi/kg).
Fill your bidons with loose mash. )
Suffer pretty regularly with cramping on 50km plus fixed rides.
Usually it'll show up when I start to spin down hill.
Really not a banana fan* so need another solution.
Uusally just carry water in my bottles, maybe I should be bunging a tablet (Nuun etc) in there too?
*Been consuming a few more bananas than usual recently as I just bought a blender and have been chucking them in smoothies. Anyone know what the half life of their anti-cramp properties is? Ie, if I have a banana in a smoothy today, will it be of any benefit when I go out for a ride tomorrow/the day after or does the banana need to be consumed at the time of exercise?
