Going Bananas for Bananas

December 1st, 2015

For most of my adult life, I’ve held the belief that bananas are to be avoided; that they are high in sugar and fat and, if consumed on a regular basis, will make you gain weight. This entire belief system was challenged recently during a sleepless night when my wandering mind landed on the topic of bananas (don’t ask, I have no idea why) and I began to ponder the whole “stay away from bananas” belief and asked myself “how many bananas could a person eat in one day?”

Needless to say, the next morning I did a bunch of research and, to my surprise, everything I read indicated that most people can consume up to three bananas a day. Whoa. What? When did that happen?

Well the good news is that if you like bananas you can enjoy them on a daily basis because eating them in moderation won’t make you fat. They make a nutritious, healthy snack and provide the body with a good source of protein, little-to-no fat, and lots of vitamins and minerals.

Here’s a nutritional breakdown of a regular-sized banana (175g) and you can decide for yourself:

Protein: 1 gram Vitamin C: 9-10 mg
Fat: 0.55 grams Vitamin B1: 0.05 mg
Cholesterol: 0 Vitamin B2: 0.1 mg
Carbohydrate: 26.7 grams Vitamin B3: 0.6 mg
Dietary Fibre: 3 grams Vitamin B5: 0.3 mg
Potassium: 450 mg Vitamin B6: 0.6 mg
Sodium: 1 mg Folate: 25 mcg
Magnesium 34 mg Iron: 0.3 mg
Manganese: 0.3 mg Selenium: 1.5 mcg
Vitamin A: 80-90 IU Zinc: 0.19 mg
Vitamin E: 0.55 IU

Wait! there’s more ….

Bananas also contain trace amounts of AMINO ACIDS – important nutrients that are the building blocks of protein – including tryptophan which is necessary for healthy nervous system function and is one of the essential amino acids that our body cannot make and (relies on food sources or supplements).

If the list of nutrients isn’t enough to convince you that eating bananas on a regular basis is a good thing, here’s a list of the health benefits eating bananas can provide:

Nervous System. Bananas help to support the nervous system and to generally help improve mood (e.g. depression, during PMS). They contain tryptophan which is converted to serotonin (one of the neurotransmitters required to promote “happy” feelings). Tryptophan has also been thought to improve and preserve memory.(1)

Blood-Sugar levels. Contrary to popular belief, bananas help to sustain blood sugar levels, not make these levels crash, and eating a couple of bananas before a strenuous workout may help to not only keep blood sugar levels more balanced, but also help improve energy output(2). They are actually listed as low-moderate on the glycemic scale, so they can be enjoyed regularly be diabetics. Some sources indicate that bananas may actually protect against type II diabetes(3). Regulating blood sugar levels also helps to improve mood in general (low blood sugar usually results in irritation and grumpiness).

Muscle cramps and Spasms. Because of the potassium and magnesium they contain, bananas can protect against muscle cramps during workouts and at night-time.

Circulation/Blood. Iron in bananas helps to build healthy blood cells. Further, the FDA officially recognizes that bananas help “to lower blood pressure and protect against heart attack and stroke”.(4)

Digestion: The pectin in bananas helps to improve bowel function and gently helps to naturally regulate the bowels by alleviate constipation and/or diarrhea. Further, the minerals in bananas help to replenish electrolytes lost during diarrhea episodes. Pectin also acts a “mop” for some heavy metals that might make their way into the gut.

Bananas are also classified as a pre-biotic. Foods in this category help establish a healthy gut environment so that good gut bacteria can grow and flourish.

Bananas can be soothing and healing to the mucous lining of the gut and are one of the few raw foods that can be eaten to relieve stomach ulcers (and not cause any undue distress). They’re also found to be a natural antacid and can provide relief for a variety of acidic conditions including acid reflux, heartburn, and GERD(5).

Other. It seems the health benefits of bananas are endless. Because of the generous vitamin B6 levels found within them, when consumed as a part of an healthy diet they also help to reduce swelling and mild fluid retention.

Bananas can also help with weight loss; eating bananas between meals as a snack reduces hunger (by stabilizing blood sugar levels). Bananas also to help lower blood pressure, protect the body against certain cancers, reduce asthma, and maintain heart health.(6)

As you can see, bananas really are good for you! One final note; before you run off to buy some bananas, there are a couple of important things to remember:

ALWAYS buy ORGANIC bananas. Why? Because bananas are among some of the most heavily sprayed commercial crops on the planet and regardless of what some people say, some (all?) of those chemicals DO get in to the edible part of the banana.

People who take certain medications – for example: beta-blockers (commonly prescribed for heart disease) and potassium supplements (prescribed when on diuretic medication) – should keep banana (and other high potassium-containing foods) to a minimum.

Beta-blockers can elevate blood potassium levels, and potassium supplements provide good amounts of potassium to begin with, so eating too many bananas may (in some cases) contribute to higher-than-normal potassium levels which could be dangerous to health.

If you’re taking these meds, you can probably enjoy bananas once in awhile, but certainly avoid eating them three times a day. As always, if in doubt check with your primary health-care practitioner.
