Nutritional and caloric values of the banana

Rich in antioxidants, the banana would prevent the appearance of many diseases. In addition, the sugars it contains would help maintain good gastrointestinal health. From a culinary point of view, there are 2 types of bananas: dessert bananas, like the ones we eat for breakfast, and cooking bananas, like the plantain.

Focus on the micronutrients contained in bananas

Bananas have their own nutritional profile. Among other things, it contains various nutrients essential to the good health of the body. Among these nutrients, we can mention the following: 

The benefits of bananas

Thanks to its unique composition, the flesh of the banana turns out to be a real daily health ally. Satisfying, rich in dietary fiber and micronutrients, it has its place as part of a varied and balanced healthy diet. 

Cancers

A prospective study, carried out among 61,000 Swiss women, demonstrated a link between high fruit consumption and a lower risk of suffering from kidney cancer. Of all the fruits studied, the researchers found the strongest relationship with bananas. The banana would have the same beneficial effect on the risk of colorectal cancer, both in women and men.

stomach ulcers

Some in vitro and animal studies tend to show that banana in the form of an extract (especially plantain, but also the dessert variety) could protect the stomach lining against ulcers. A study has shown that the extract of 2 varieties of bananas grown in Thailand (Palo and Hom) would have a gastroprotective potential in rats. However, only the Hom variety is said to have an effect on healing ulcers. This type of banana would be close to the Cavendish, the most widespread variety in the world. Current research, however, is insufficient to recommend the consumption of bananas for the prevention or treatment of gastric ulcers.

Chronic diarrhea 

A few studies conducted in Bangladesh have shown that eating bananas can reduce the symptoms of chronic diarrhea in children. In some cases, a mixture of rice and cooked plantains or a mixture of rice and pectin could decrease the number and weight of stools, as well as the duration of diarrhea in babies. In other cases, the consumption of unripe bananas (½ to 3 bananas per day, depending on the age of the children) hastened the healing of acute and chronic diarrhoea. Another study carried out in Venezuela showed that a diet comprising a preparation based on cooked plantain reduced the number and weight of stools, the duration of diarrhea and promoted weight gain, compared to a traditional preparation based on yogurt.

Also, the unripe banana contains resistant starch, a type of sugar that resists the action of digestive enzymes (in the same way as dietary fiber) and which goes intact in the colon. Under the action of the intestinal flora, the undigested starch then undergoes a fermentation there, which transforms it into fatty acids with short chains (for example butyric acid). These stimulate the absorption of liquids and salt in the colon, thus reducing the loss of water in the stool. Short-chain fatty acids would also indirectly improve the permeability of the small intestine, a phenomenon that helps relieve the symptoms of diarrhea.

Cardiovascular illnesses

A study indicated that a high consumption of bananas during a meal (400 g, or more than 3 bananas) reduced the free radicals present in the body, 2 hours after the meal. This diet decreased the oxidation of LDL-cholesterol (bad cholesterol), a process involved in the development of cardiovascular disease. However, other studies will be necessary in order to target the effects of bananas in the longer term and with more moderate doses.

Type 2 diabetes 

The resistant starch (a type of sugar) in unripe bananas is said to contribute to weight loss in obese individuals suffering from type 2 diabetes, as well as to improve the sensitivity of cells to insulin. A resistant starch extract from unripe bananas is also thought to lower insulin secretion and glycemia (blood sugar levels) in both healthy individuals and those with type 2 diabetes.

Researchers have observed that resistant starch decreases the absorption of sugars consumed at the same time, which leads to a decrease in glycemia (blood sugar level). Additionally, regular consumption of resistant starch would lead to a greater increase in mealtime ghrelin, a hormone that has been linked to improved insulin sensitivity.

Antioxidants and carotenoids

Although the banana is not among the fruits that contain the most antioxidants, it still has a high antioxidant capacity, which could possibly help prevent the onset of certain cancers, cardiovascular diseases and various chronic diseases. The very popular Cavendish banana is said to contain dopamine, a molecule from the catecholamine family. Dopamine demonstrated antioxidant activity similar to that of vitamin C, the most potent water-soluble antioxidant. As banana contains both dopamine and vitamin C, this could explain its high antioxidant capacity. Plantain is also an important source of several phenolic compounds that are well absorbed by the body, thus optimizing their antioxidant potential.

A flavonoid antioxidant, leucocyanidin, has been extracted from unripe plantains. This active compound has demonstrated a protective effect against the erosion of the stomach lining, following the intake of aspirin.

The plantain banana contains beta and alpha-carotene, 2 carotenoids with the ability to transform into vitamin A in the body. Of all the carotenoids, beta-carotene is the most efficient in converting to vitamin A. The latter promotes the growth of bones and teeth, keeps the skin healthy and protects against infections.

Nutritionist’s word

Plantains contain more resistant starch than sweet bananas. Also, as the banana ripens, the amount of resistant starch decreases to such an extent that only bananas that have not reached their optimum ripening stage would contain resistant starch in significant amounts.

How to choose the right banana?

If the annual consumption of bananas per person is 2 kg in China, 10 kg in Europe and 12 kg in the United States, it increases to 50 kg in Oceania and 210 kg or more in African countries. from the east. A variable consumption, therefore, for this fruit with a unique nutritional profile.

Choose the banana according to its color  

The more green marks the banana has, the less ripe it is and the longer it will keep. It can then be used for cooking. On the other hand, it will have to be left to mature before consuming it raw, because at this stage, it is indigestible. It is ready to eat when the flesh yields slightly to pressure and the skin is very yellow and slightly tiger-colored, without any green coloration. When it shows brown or black spots, it has passed this stage and is then better suited for cooking. Note that small bananas are generally sweeter than large ones.

The plantain banana is generally sold when its skin is green.

Derivatives

You can find a pink red banana in specialized grocery stores, which can be eaten raw or cooked. Commercial dried bananas often contain added sugar: read the label carefully.

“Banana essence”, which is used to flavor liqueurs and confectionery (as well as certain processed cheeses), is in fact amyl acetate, a synthetic substance obtained from the acid acetic. Natural banana essence is too volatile to be of culinary interest.

Finally, there are frozen banana leaves in Asian grocery stores, which can be used to cook food in foil.

When to peel the banana? 

Do not peel the banana until ready to eat or prepare it, because its flesh oxidizes on contact with air. If it is necessary to peel it in advance, it is lightly lemoned.

The plantain peels more easily after it has been blanched for 5 minutes in salted boiling water.

How to prepare the banana

From a culinary point of view, there are 2 types of bananas: dessert bananas and cooking bananas. In this last category, the plantain banana is by far the most widespread. For each of these types, there are a multitude of varieties giving fruits that vary considerably in size, shape, color and flavor. Most of these varieties are unknown outside their countries of production. The main banana producing countries are located in Latin America and Asia, as well as in Africa for cooking bananas. Virtually all dessert bananas exported worldwide come from a single variety, the Cavendish.

Contraindications

Although excellent for health, the banana remains an allergenic fruit for many people. It is therefore advisable to be careful and attentive to the signs of a possible oral allergy, which can have serious consequences if it is not treated in time. 

Beware of allergies

Banana is a food implicated in oral allergy syndrome. This syndrome is an allergic reaction to certain proteins from a range of fruits, vegetables and nuts. It affects some people with allergies to environmental pollens and is almost always preceded by hay fever .

Thus, when some people eat the banana raw (cooking usually degrades allergenic proteins), an immunological reaction may occur. These people experience itching and burning sensations in the mouth, lips and throat. Symptoms may appear and then disappear, usually within minutes of eating or touching the offending food. In the absence of other symptoms, this reaction is not serious and banana consumption does not have to be systematically avoided. However, it is recommended to consult an allergist to determine the cause of reactions to plant foods. The latter will be able to assess whether special precautions should be taken.

People allergic to latex may demonstrate hypersensitivity to bananas as well as other foods such as kiwi and avocado. Reactions are diverse, ranging from hives to anaphylactic reactions. Given the potential seriousness of the reactions, very special care should be taken when consuming these foods in people who know they are allergic to latex. Again, it is recommended to consult an allergist in order to determine the cause of reactions to certain foods as well as the precautions to be taken.

History and anecdotes

The term “banana” appeared in 1602. It comes from the Portuguese banana, borrowed, according to some, from a Bantu language; according to others, to an Arabic word meaning “finger”. The fruit was first referred to as ‘apple of paradise’ and ‘garden fig’.

The term “plantain” to designate the plantain banana first appeared in the form of “plantin” at the beginning of the 17th century. It derives from the Spanish platano, which designates the plane tree, a tree having nothing to do with the banana tree. We do not know why the Spaniards who landed in South America named it so. Note that “plantain” also refers to a small herbaceous plant whose name derives from the Latin plantago.

A little history

The banana tree is one of the oldest known plants. It is probably also one of the first to have been domesticated. However, it is believed that the fruit was hardly consumed by our hunter-gatherer ancestors since, before the domestication of the plant, it was not very fleshy and contained many inedible seeds. On the other hand, we very probably consumed its buds as well as its internal leaf sheaths. Primitive fishermen used the fibers of its stem to make nets. The leaves also had various uses.

The Musaceae family includes only 2 botanical genera, Musa being by far the most widespread and diverse. This genus is subdivided into many species (from 30 to 50, according to experts), several of which still grow in the wild. However, the majority of banana and plantain varieties are derived from the M. acuminata and M. balbisiana species or their crosses.

Native to Southeast Asia, the banana tree followed human migrations to the Indian peninsula, the Pacific islands and Africa. Under the influence of natural evolution and human intervention, it has greatly diversified. In Africa, farmers grow a wide range of plantains, distinctly different from those in the Pacific zone, as well as another group of cooking bananas, with their own characteristics.

As the banana does not keep well and is easily damaged during transport, it will take time to be known in the West. It does not seem to have been consumed by the Egyptians, the Greeks or the Romans, and would not have appeared in the Near East until the 7th century AD. It did not spread to Europe and North America until the 19th century, when ships were faster and conservation methods better mastered.

Consumption varies by region

If the banana is considered a simple dessert or a snack in rich countries, it is quite different in Africa, Asia and South America. For nearly 400 million people, it is a subsistence food, to be put on the same footing as nutritious tubers, such as taro, cassava or sweet potato. The research carried out in these regions by national and international organizations is of great importance. They aim to increase the productivity of banana plantations and find solutions to the problems of diseases and insects that attack this crop.

Besides the fruit, in various parts of the world, the young shoot, the base of the stem or the male flower are eaten. Ashes from burnt leaves are used as salt in Asia. Some banana species are only grown as ornamental plants. Others are used to produce fibers to make ropes, fabric, paper, baskets, carpets, roofing materials and are called “Manila hemp”.

The banana tree and its diet

The banana tree is not a tree, but rather a giant grass. The trunk is actually a pseudostem, made up of leaf sheaths (leaves that overlap at the base).

The set of bananas produced on the same plant (from 100 to 400) is called a “bunch”, which is divided into groups of 10 or 20 fruits called “hands” or “legs”. The individual fruits are called “fingers”.
