When I was a kid you couldn't pay me to eat a spotted banana. I wasn't trying to
be a diva, I just hated the taste of a spotted, bruised, or otherwise
“imperfect” banana. Now that I pay my own bills, I could probably be bribed to
eat a banana that is, in my opinion, past its prime. According to research, if
you're like me you are eating bananas the wrong way – or at least at the wrong
time. Unless you eat with the peel on, and then that's just plain wrong.
When is a banana ripe?
A lot of people will say when a banana turns from green to yellow it's ripe.
Unfortunately, they're wrong. Spots indicate a banana is ripe and at its
nutritional peak. A ripe banana also peels easily and has no green on it, not
even near the stem. Not only are spotted bananas easier to digest, they also
contain more antioxidants.
Bananas and health
Ripe and unripe bananas are good sources of potassium, fiber, and vitamins B6
and C. However, the longer you wait to eat a banana, the greater its
concentration of antioxidants, according to Japanese researchers.
The researchers also found that ripe bananas make a substance called tumor
necrosis factor. TNF fights cells that are cancerous and otherwise abnormal. The
riper the banana, or the darker the spots, the better it is to eat for cancer
prevention. Generally, ripe bananas are eight times better at boosting your
immune system than unripe bananas.
Should you ever eat an unripe banana?
There is one benefit to unripe bananas: a high resistant starch content. Most of
the carbs in unripe bananas are starch while most of the carbs turn to sugar in
a ripe one. That's why riper bananas taste sweeter.
People who need a low sugar intake, such as type 2 diabetics, might prefer the
unripened banana. However, the higher resistant starch content could cause
bloating or intestinal gas, so beware or consume alone. Alternatively, try
eating some peanut butter or almond butter with ripe bananas to slow down the
sugar absorption and prevent spikes.
If you're unsure whether ripe bananas are better for you, check with your
doctor. It is recommended that people consume 3.5 to 5 cups worth of produce per
day, and yet hardly anyone does this. According to the Centers for Disease
Control and Prevention, less than one percent of adolescents meet the daily
produce requirement while only around 2 percent of adult males and 3.5 percent
of adult females get enough. Therefore, don't avoid bananas unless you have a
medical reason to do so.
