Both plantains and bananas belong to the Musaceae family, with similar nutritional values. However, they are distinct species with noticeable physical differences. The online claim that "plantains have three ridges while bananas have five" is overly simplistic.Additionally, the presence or absence of ridges on bananas merely indicates different varieties and has no bearing on nutritional value. A banana's nutritional content primarily depends on its growing environment, including climate and soil conditions.
Since plantains are less commonly consumed, their cultivation area is smaller, leading to higher prices.As some fruit vendors note, the "emperor banana" is not a plantain but belongs to the Cavendish banana category.
So how can we tell them apart? Experts offer these tips: First, examine the shape: Bananas are elongated with a short stem, while plantains are shorter with a long stem.Second, examine the color: Some bananas develop black sesame-like spots on their skin; more spots indicate better flavor. Plantains rarely exhibit these spots. Third, taste the fruit: Bananas offer a sweeter, more pleasant taste than plantains, which tend to be more acidic.
Whether bananas relieve constipation depends on individual constitution. Medical experts also note that claims bananas cause constipation lack scientific basis. Both bananas and plantains are cooling fruits that promote bowel regularity. However, those with weak constitutions should consume them sparingly and avoid eating them on an empty stomach.Though both bananas and plantains have laxative effects, why do some people experience no relief or even worsened constipation after eating them?
Traditional Chinese medicine practitioners emphasize that treating illness requires pattern differentiation. This principle also applies to consuming fruits and foods. Eating bananas healthily involves more than just considering individual constitution; proper consumption methods matter too.Traditional Chinese medicine generally classifies constipation into four types: heat-type constipation, qi-type constipation, cold-type constipation, and deficiency-type constipation. Heat-type constipation arises from rising internal heat (commonly referred to as "heatiness"), while qi-type constipation stems from stagnant qi flow. Bananas, being cold in nature, can alleviate these two types of constipation. However, for those with the latter two types—who often have inherently weak and cold spleen-stomach systems—consuming bananas may have the opposite effect.Instead, they may benefit from nuts like almonds to promote bowel regularity. Additionally, TCM practitioners note that bananas' effectiveness varies by individual. Some with sensitive constitutions may experience relief, while others see little effect. Do not increase intake solely because the laxative effect is mild.Banana consumption should be moderate. Those with robust constitutions who benefit from bananas should limit intake to 1-2 per day. Nutrition experts also note that plantains and bananas share similar nutritional value, both being high-potassium foods.
They are also rich in magnesium. Modern medicine confirms that potassium helps maintain normal blood pressure and heart rhythm, preventing hypertension and muscle cramps, while magnesium aids in fatigue recovery. Furthermore, the sugars in bananas convert rapidly into glucose, providing an immediate energy boost—a reason many athletes favor them during competitions.
