According to an article in today's National Post, he's right. Cutting a potato into smaller pieces helps it cook faster, but you lose more potassium into the water.
Potatoes and bananas are main food sources of potassium.
A teenaged hockey player on Dave's team collapsed after dry-land and on-ice training in the summer. The diagnosis: low potassium levels.
Keep well-hydrated with water when exercising, and snack on bananas.
Some people find they are more attractive to biting insects like mosquitoes after eating bananas. Hikers and campers might want to get their potassium from potatoes.
Don't worry about getting too much potassium unless you have kidney damage.
Healthy kidneys flush out excess potassium.
If you need to regulate potassium intake, ask your doctor or a dietician if there are foods you should avoid, and how best to prepare the foods you like.
Peel a banana from the bottom like primates do, and you won't have to pick off the little strings.
To keep bananas longer, take your bananas apart from the bunch.
Separated, single bananas won't ripen as quickly as they will when connected at the stem.
