The Cardiovascular Protection Offered by Bananas

Bananas, often overlooked amidst a plethora of fruits in supermarkets, hold remarkable health benefits that extend far beyond their convenience and taste. Rich in essential vitamins such as B, C, and A, bananas are also low in calories and fat while boasting high levels of potassium—a vital mineral crucial for maintaining normal blood pressure and heart function.

Potassium, a cornerstone of cardiovascular health, plays a pivotal role in regulating blood pressure and ensuring the smooth functioning of muscles and nerves. With an impressive 467 mg of potassium per average serving and minimal sodium content, bananas offer a natural and effective means of preventing high blood pressure and safeguarding against atherosclerosis. Consuming just one banana daily can significantly contribute to meeting the recommended daily intake of potassium, which stands at around 3 grams.

Moreover, the high fiber content in bananas further fortifies their cardiovascular benefits. Studies have shown that individuals with a higher fiber intake, around 21 grams per day, experienced a notable 12% reduction in coronary heart disease and an 11% decrease in overall cardiovascular disease risk compared to those with lower fiber consumption, around 5 grams daily. Furthermore, the soluble fiber found abundantly in bananas yielded even more promising results, correlating with a 15% lower risk of coronary heart disease and a 10% reduction in total cardiovascular disease risk.

Beyond cardiovascular advantages, the potassium present in bananas holds promise for promoting bone health. In the face of the prevalent high-salt diets prevalent in many Western societies, potassium acts as a counterbalance, mitigating the increased urinary calcium loss induced by excessive sodium intake. By doing so, potassium aids in thwarting rapid bone thinning, thus contributing to the maintenance of robust skeletal structure and reducing the risk of osteoporosis.

In conclusion, bananas emerge as a nutritional powerhouse, offering a myriad of benefits for cardiovascular health and beyond. From regulating blood pressure to bolstering bone density, the potassium-rich fruit presents a simple yet potent ally in the pursuit of overall well-being. Incorporating bananas into one's daily diet represents a practical and delicious strategy for nurturing a healthy heart and body.

Vitamin B in banana: Importance for human health

Bananas are found to be an excellent source of vitamins. Among vitamin B in banana and plantain: Thiamine (B1), Riboflavin (B2), Niacin (B3), Folate (B9), Pantothenic acid (B5) and Pyridoxine (B6)

*Folate (Vitamin B9) enables red blood cell production (erythropoiesis). It enhances immunity levels and biosynthesizes nucleic acids, nerve tissues (brain functionality) and proteins. It helps in DNA damage risk prevention and immunological homeostasis.

Folate is also important as it helps the body as a coenzyme to
• form blood cells in the bone marrow
• ensure rapid cell growth in infancy, adolescence, and pregnancy
• control (together with vitamin B6 and vitamin B12) blood levels of the amino acid homocysteine, associated with certain chronic conditions such as heart disease.

*Pantothenic acid is essential for the metabolism of fatty acid. Pantothenic acid has antistressor properties which also contribute to the production of neurotransmitters. (Contain about 0.26 mg/100g in banana)

*Dietary riboflavin contributes to the generation of inflammatory and immunity signaling molecules within immune cells through the mechanism of NADPH oxidase 2 priming. (Riboflavin in banana 0.04-0.07 mg/100g)

*Bananas contain 25 percent of the recommended daily allowance (RDA) for pyridoxine (vitamin B6). Pyridoxine enhances immunity integrity via the linkage formation between chemokines and cytokines, while it enhances immune feedback towards increased antibody output. Pyridoxine also promotes brain health, heart health, and more. (contain about 0.51 mg/100g in banana)

*Thiamine (Vitamin B1) essential both as a coenzyme and noncoenzyme, and is involved in many processes, particularly in energy transformation, and oxidative and nonoxidative carbohydrate metabolism. It is centrally important in nerve functioning and energy generation from carbohydrates. 

Thiamine modulates the neurological transmission system, improves brain functionality, protects the peripheral nervous system from compromise, and is involved in synthesizing myelin. (Thiamine in banana 0.04-0.08 mg/100g).

*Niacin (Vitamin B3), shown in Figure 13, is anti-inflammatory and immunohomeostatic in its activity. It inhibits the multiplicity of pro-inflammatory cytokines and the tumor necrosis factor usually effected by monocytes and macrophages.

Vitamin C (L-ascorbic and L-dehydroascorbic acids) content in banana

Vitamin C (Ascorbic acid) is the most important vitamin in fruits and vegetables. Vitamin C is a group of analogues of ascorbic acid, highly soluble in water. Most plants and animals synthesize it for their own requirement but the human body is unable to synthesize vitamin C due to lack of an enzyme gulonolactoneoxidase. Banana is vitamin rich contains of vitamin C (10-20 mg/100g).

This vitamin plays important roles in various metabolic processes in human body from acting as co-substrate for many enzymes, maintenance of redox to neurophysiological functions, including collagen synthesis, wound healing and many positive effects on chronic degenerative diseases.

It functions in absorption of inorganic iron, reduction of plasma cholesterol level, inhibition of nitrosoamine formation, enhancement of the immune system, and reaction with singlet oxygen and other free radicals.

Nutrient values of 100 g edible portion of banana is adequate to fulfill the carbohydrates and vitamin C daily values for babies aged one to three years old whereas for adults need more quantities. About 300 g of bananas are needed to fulfill vitamin C for female adults per day whereas male adults need 400 g.

Vitamin E content in banana

Banana is rich in many bioactive compounds, such as carotenoids, flavonoids, phenolics, amines, vitamin C, and vitamin E having antioxidant activities to provide many human health benefits. Banana contains about 0.1 mg/100 g of α –tocopherol. 0.02 mg/100 g of γ-tocopherol and 0.01 mg/100g δ-tocopherol

Vitamin E includes tocopherols and tocotrienols. They can be in eight different forms (four tocopherols and four tocotrienols). All the isomers have aromatic rings with a hydroxyl group that can donate hydrogen atoms to reduce reactive oxygen species (ROS).

It protects the skin from various deleterious effects due to solar radiation by acting as a free-radical scavenger. Experimental studies suggest that vitamin E has antitumorigenic and photoprotective properties.

Vitamin E acts mainly as an antioxidant preventing polyunsaturated fatty acids from being damaged by lipid peroxidation. Oxidative damage has been linked to numerous chronic diseases conditions, including cardiovascular diseases and cancer, and dietary vitamin E intake and lower circulating vitamin E concentrations have been linked to cardiovascular disease and cancer in observational studies.

Vitamin B6 in bananas

Bananas are economical food and provide a significant amount of vitamin B6. Therefore, they are well posited as a readily available source of vitamin B6 for the elderly.

Bananas contain about 40 % of daily recommended amount of vitamin B6. In general, consuming 1.5 to 2 bananas would provide the recommended intake of vitamin B6 each day throughout most of the life span.

A 100 -gram serving of bananas provides 0.58 milligrams of vitamin B6. Thus an average sized banana (120 grams) would provide 0.7 milligrams of this vitamin.

Although extreme deficiency of vitamin B6 is to be quite rare, numerous clinical studies have demonstrated the importance of vitamin B6 in a number of health conditions that typically respond to vitamin B6 supplementation, including asthma, premenstrual syndrome, carpal tunnel syndrome, depression, morning sickness and kidney stones.

Premenstrual syndrome is remedied from consuming bananas because the B6 property regulate blood glucose levels, which can affect the person mood.

Vitamin in Banana

Banana is a good source of many vitamins and minerals particularly vitamin A, vitamin B and vitamin C.

Many of banana varieties contain high levels of provitamin A carotenoids, the source of the yellow or orange color of the fruit.

The importance of carotenoids becomes clear when one considers that vitamin A deficiency affects around 120 millions children a year. Vitamin deficiency has many effects including weakening the immune system and causing blindness.

Because they contain vitamin A bananas and plantains act as an aid to digestion, and it is reported that boiled mashed ripe fruit can be good for constipation, especially when mixed with other recommended plants.

Banana contains about 10-25 mg of vitamin C per 100 g, though figures as high as 50 mg have been quoted in some varieties.

The quantity is the same whether it is ripe or unripe. Vitamin C in banana helps the body to heal and defend against infections.

Vitamin C also is valuable in the absorption of iron, synthesis of connective tissue, and blood formation.

Banana: The Ideal Food

Banana: The Ideal Food
Healthy, filling and even already wrapped for the consumer, bananas are one of nature’s ideal foods and the world’s most popular fruit.

They are undoubtedly an extremely healthy food, and the healthy conscious late 1990s is a highly appropriate point at which to begin a study of the expanding international banana trade.

Bananas contain nearly all the essential vitamins – in particular vitamins C, B6 (pyridoxine), B2 (riboflavin) and folate – as well as magnesium and potassium.

Potassium is a vital mineral for muscle development and also helps to regulate blood pressure.

These advantages are demonstrated strongly in comparison with other fruits but, equally importantly, bananas also have discernible health and nutrition advantages by comparison with other snack foods, notably chocolate bars.

No other fruit is so readily or so widely eaten as a snack in developed countries. Bananas also rarely cause allergic reactions, apart from migraine headache and indigestion in a few adults, and are a popular first solid food for babies.

They are also useful for treating childhood stomach upsets, although there is as yet no firm evidence to support the theory that bananas may help cell and mucus production in the stomach lining, thereby healing ulcers and preventing new ones.

Aside from these general properties, the banana industry has been assiduous in promoting the use of the fruit for specific dietary needs, most notably by sportspeople such as tennis player and racing cyclists, who have an increased need for vitamins and minerals as well as for carbohydrates without associated fats.

Bananas also contain a high level of natural sugar, in both their fresh and dried form, which they release quickly into the blood stream.

The banana industry has also pointed out that the unique combination of vitamins and sugars within bananas releases energy into the body over a long time, improving stamina and the powers of endurance and concentration.

Banana and Nutrition

Banana and Nutrition
Through out the western non-Mediterranean world, there has been since the 1970s a steadily rising awareness of the importance of diet to health. There is now little doubt that choice of diet contributes to the risk of developing diseases such as heart disease, strokes, some cancers, diabetes, bowel disease, gallstones, dental caries and osteoporosis – though to what degree is not yet known.

Northern Europe and United States, have sought with varying degrees of success to reduce saturated fat consumption, i.e. sugar not contained within the cell wall of a plant or animal food. By comparison, bananas contain their sugar content – fructose, sucrose and glucose – intrinsically, as well as containing substantial amounts of fiber (non-starch polysaccharides) which is helpful for digestion. Unripe banana contain ‘resistant’ starch, which is indigestible in the human small intestine. The nutritional qualities of the banana actually change with ripening, the sugar percentage rising form 2% to around 23% and the starch percentage falling from 23% to 1%.

Banana is high in vitamin B6, which helps fight infection and is essential for the synthesis of heme, the iron containing part of hemoglobin. The banana is a good source of vitamin C, needed to help fight infections. The combination of a good amount of potassium and low sodium may help protect against high blood pressure. As an easily digestible source of fiber, the banana is valuable in preventing both diarrhea and constipation. It has a creamy texture often associated with fatty foods, yet is virtually fat free.
