Here in Japan, we get our bananas from the Philippines, something the Japanese should enjoy while oil used to ship them 2,000 miles is still cheap and available. We eat them every day starting with oatmeal and bananas for breakfast. Two bananas will give you about 1000 mg of potassium which is great for your cardiovascular system, as well as about 90 mg of magnesium and many vitamins. They can help to counteract all that excess table salt you probably get if you eat a Western diet.
Today, K found bananas on sale - 5 for 100 yen (about 86 US cents). These bananas are each about 220 grams, so for my US friends that works out to about 35 cents a pound. She bought ten and used some to make banana bread with blue berries (yum!).
What got me on the banana thing tonight, besides banana bread? .... no, not the "papa's got the shipfitter blues, and loving you has made me bananas" song... It was a post on Peceli and Wendy's blog, Babasiga. Wendy is used to getting about 6 bananas for a dollar in Fiji, but right now she's at their Australia home and bananas have become scarce. I'll let you visit her blog and read why that is and about how much she had to pay for ONE banana. (Hint for all you carnivores out there: how much does steak cost?).
Hopefully, you don't have to pay too much for this wonderful fruit. In addition to the benefits mentioned above, they can help protect you from stroke and ulcers, lower your blood pressure, and give you a boost of energy to start the day. Even when they are expensive they are probably cheaper than prescription drugs for doing those things and have no side effects that I know of.
