_{Banana one of your best sourcesof potassium}

Because of their impressive potassium content, bananas are highly recommended by doctors for patients whose potassium is low. One large banana, about 9 inches in length, packs 602 mg of potassium and only carries 140 calories. That same large banana even has 2 grams of protein and 4 grams of fiber. No wonder the banana was considered an important food to boost the health of malnourished children! Those reducing sodium in their diets can't go wrong with a banana with its mere 2 mgs of sodium. For the carbohydrate counters there are 36 grams of carbs in a large banana.

A full range of B vitamins are present with:
• .07 mg of Thiamine
• .15 mg of Riboflavin
• .82 mg Niacin
• .88 mg vitamin B6
• 29 mcg of Folic Acid.

Putting all of the nutritional figures together clearly shows the banana is among the healthiest of fruits.

The banana plant, often erroneously referred to as a "tree", is a large herb, with succulent, very juicy stem (properly "pseudostem") which is a cylinder of leaf-petiole sheaths, reaching a height of 20 to 25 ft (6-7.5 m) and arising from a fleshy rhizome or corm. Suckers spring up around the main plant forming a clump or "stool'', the eldest sucker replacing the main plant when it fruits and dies, and this process of succession continues indefinitely.

As the young fruits develop from the female flowers, they look like slender green fingers. The bracts are soon shed and the fully grown fruits in each cluster become a "hand" of bananas, and the stalk droops with the weight until the bunch is upside down. The number of "hands" varies with the species and variety.

Brazil is the leading banana grower in South America—about 3 million tons per year, mostly locally consumed, while Colombia and Ecuador are the leading exporters. Venezuela's crop in 1980 reached 983,000 tons. Large scale commercial production for export to North America is concentrated in Honduras (where banana fields may cover 60 sq mi) and Panama, and, to a lesser extent, Costa Rica. In the West Indies, the Windward Islands of Martinique and Guadeloupe are the main growers and for many years have regularly exported to Europe. Green bananas are the basic food of the people of Western Samoa and large quantities are exported.

The edible bananas are restricted to tropical or neartropical regions, roughly the area between latitudes 30°N and 30°S. Within this band, there are varied climates with different lengths of dry season and different degrees and patterns of precipitation. A suitable banana climate is a mean temperature of 80°F (26.67°C) and mean rainfall of 4 in (10 cm) per month. There should not be more than 3 months of dry season.
