Whoever the person was going on about how much potassium per/kcal there is in Tea and Coffee didnt stop to think about the weight of tea required to make a kcal.
Lets put it straight - 1 cup of brewed tea provides… from RDAs according to USDA
2% riboflavin
3% folate
26% manganese
3% potassium
1% copper
so, to be getting 100% of your potassium levels - you need about 33 cups of brewed tea[/quote]
Where did I say that people should be relying on tea for 100% of their potassium needs?
Let’s recap. In the context of getting sufficient potassium in the diet, someone had mentioned that “a few bananas a day” took care of his needs. Perfectly reasonable.
But it reminded me of something I’ve noticed many times, and which always irritates me: mention “potassium” to the average person, or even to a doctor, and they’ll say “Oh yeah, bananas!” - as if they are a uniquely rich source of this nutrient.
Bananas are inexpensive and convenient, but there’s nothing special about them when it comes to potassium! Almost all foods contains ample amounts of potassium, and many foods contain more than bananas. Heck, there’s twice as much potassium in a large serving of McDonald’s fries than in a large banana (look it up:
http://www.nal.usda.gov/fnic/foodcomp/search/ ), and the average person probably prefers french fries over bananas.
So why don’t people say “Oui, French fries!” when you mention potassium? Cause fries ain’t healthy! Why? Well, besides the trans fats, that serving of fries has over five times as many calories as the banana.
So I thought it would be interesting to rank some common “healthy” foods in terms of how much potassium they contained per calorie, as opposed to per serving. Thus, my earlier post.
Obviously, I should have left coffee and tea off the list. While making for interesting side discussions, I’m afraid they’ve stolen too much attention from my anti-banana jihad.
