How many bananas a day is too many?


Quote  |  Reply

I eat a lottttt of bananas.  A medium sized banana has 422g potassium  -- how many grams of potassium a day is dangerous?

 

I'm a 17 yr old female.

How many bananas is a lot? 2? 4? 50? There are calculators you can find online that tell you the individual breakdown of your nutritional needs. I would recommend finding that and then figuring out how many bananas will fit in there!

I'm the same- I eat at least two bananas a day! Usually frozen and in a smoothie, mind; but they're still amazing. :] I looked up "potassium" on wikipedia and got this from it:

"The 2004 guidelines of the Institute of Medicine specify a DRI of 4,000mg of potassium, though most Americans consume only half that amount per day."

Hope that helps?

Alysha,

I don't think it is possible to eat too many bananas a day. I highly doubt you could OD on potassium from a natural food, unless you are on dialysis, but you would have already been told to stay away from food like that.

I eat between 2-4 bananas every day. Some people might say it's too much sugar, but it has got to be better than 2-4 snicker bars! BTW, I am a 42 year old, 160 pound male.

Hope this helps,

Brad

Anything > 0 is too much banana for me, but that's because the sugar in them is mean to me.

You can OD on potassium, but it takes an awful lot.  Like, drinking gallons of OJ in a day would do it.  A bunch of bananas every day probably isn't going to kill you.  But I do have to put in the disclaimer that I'm not a doctor, so what the heck do I know?

I don't think bananas will kill you! Bananas apparently also trigger the 'happy' feeling in your brain, and while they are more calorific than some fruits they're a really good pre/post-exercise boost.

However, I think they only count as one piece of fruit no matter how many bananas you have. If you eat five bananas a day, it's not reaching your five-a-day, you have to eat other fruit like apples, peaches, kiwis...and veggies..thats what i heard anyways...

While we're on the topic of 'too much', is tuna really that bad? I heard that too much tuna can lead to mercury poisoning...not that i eat loads of tuna...

r2r2-  If you eat 5 bananas it does not only count as 1 piece of fruit. It doesn't matter if you eat 5 of the same type of fruit, each piece is still "a serving" of fruit. 

It is, however, recommended that you get your 5-9 servings of fruits and veges from a variety of fresh and/or frozen sources if possible! Eating a variety of healthy foods with many colors helps to ensure you are getting adequate nutrients to meet your RDI's...

To answer the question as to whether or not you can OD on bananas, I think it would be very difficult... It is highly unlikely that you will reach toxicity levels for potassium by eating too many bananas. The only time you would have to worry about that is if you had advanced kidney disease of were on certain heart related prescription drugs.

Hope this helps...

i just wanted to say that no medium sized bannana contains 422g of potassium, not medium bannana even wieghs nearly half a kilogram.

 

just so you know

just FYI, many dietitians and nutritionists tell you to refrain from counting any sugar that comes from fruit. That is good sugar that your body needs. Its the added sugar you should be worrying about ! i'd say eat as many many as you please :)

Bananas are high glycemic and very sugary. From what i've learned about nutrition, sugary foods are never an optimal source of nutrition even when they contain other nutrients/anti-oxidants.

"just FYI, many dietitians and nutritionists tell you to refrain from counting any sugar that comes from fruit."

To lump 5-9 servings of fruit-veggies in one category is criminal. The two groups should be separated. 1-2 servings of fruit, 5+ servings of low starch veggies.

I don't think its a good idea to throw out moderation when it comes to fruit. Fruit doesn't nessacarily need to be avoided entirely because there are redeeming qualities (well, if you're trying to lose weight reducing sugary carby stuff like fruit is always a good idea- berries tend to be lower in sugar). But honestly, you can get everything you need from veggies without fruit, there is way more potassium in spinach (I bet you hate spinach though right?)! The problem is, we don't like the taste of veggies, we like fruit because its sugary. Fruit should be a dessert, not a snack IMHO, because of the fructose issues. Fructose/sugars are way worse for us then people seem to think... 

Even when not dieting, eating fruit in moderation is ok, but the fact is fruit is sugary- fructose. Fructose is 20-30 times more glycating the glucose, glycation is very damaging to the body. Its not about the calories when it comes to fruit, its about the fructose! Yes, its better then a snickers bar, and doesn't have the same impact. Its a whole food- but its still fructose, it still a sugary carby food, and the body still processes the same way as any other sugary food.

Keep in mind fruits tend to be heavily sprayed with pesticides/herbicides/fungicides- check out the dirty dozen- many popular fruits are high up on that list (apples, peaches, cherries,strawberries,blueberries). Bananas thankfully aren't high on the list, and they have a skin so exposure is reduced. But there is exposure none the less.

i think we all know that moderation is the key! just saying eating 3 bananas a day won't kill you.

I dont remember saying eating 3 bananas will result in Sudden death. I was just making a point about the fructose in fruit, that it can be unhealthy to eat 3 bananas a day due to the facts of life- the way fruit is processed in the body. 

they're only a problem if its crowding out other essential nutrients (protein, fat, vitamins), like with anything else.

I think just like everything else, moderation is important. I would try to avoid leaning heavily on any one food item. I'm sure a few won't hurt you but any more than that on a regular basis will probably throw your overall nutritional profile out of balance as suggested above.
