The Fruit Of The Week - Banana

Fruit Information: 

Southeast Asian farmers first domesticated bananas. Recent archaeological and palaeoenvironmental evidence at Kuk Swamp in the Western Highlands Province of Papua New Guinea suggests that banana cultivation there goes back to at least 5000 BCE, and possibly to 8000 BCE. It is likely that other species were later and independently domesticated elsewhere in southeast Asia. Southeast Asia is the region of primary diversity of the banana. Areas of secondary diversity are found in Africa, indicating a long history of banana cultivation in the region. - Tracing antiquity of banana cultivation in Papua New Guinea 

All widely cultivated bananas today descend from the two wild bananas Musa acuminata and Musa balbisiana. While the original wild bananas contained large seeds, diploid or polyploid cultivars (some being hybrids) with tiny seeds are preferred for human raw fruit consumption. These are propagated asexually from offshoots. The plant is allowed to produce 2 shoots at a time; a larger one for immediate fruiting and a smaller "sucker" or "follower" to produce fruit in 6–8 months. The life of a banana plantation is 25 years or longer.

Cultivated bananas are parthenocarpic, which makes them sterile and unable to produce viable seeds. Lacking seeds, propagation typically involves farmers removing and transplanting part of the underground stem (called a corm). Usually this is done by carefully removing a sucker (a vertical shoot that develops from the base of the banana pseudostem) with some roots intact. However, small sympodial corms, representing not yet elongated suckers, are easier to transplant and can be left out of the ground for up to 2 weeks; they require minimal care and can be shipped in bulk. -  The Unfortunate Sex Life of the Banana

Nutritional Benefits: 

Bananas are a very good source of Vitamin B6. 

At least one preliminary study has found that this vitamin may increase dream vividness or the ability to recall dreams. It is thought that this effect may be due to the role this vitamin plays in the conversion of tryptophan to serotonin. There is anecdotal evidence suggesting supplemental Vitamin B6 may be associated with lucid dreaming. - Effects of pyridoxine on dreaming: a preliminary study. Perceptual & Motor Skills 

Vitamin B6 has a role in preventing heart disease. Without enough pyridoxine, a compound called homocysteine builds up in the body. Homocysteine damages blood vessel linings, setting the stage for plaque buildup when the body tries to heal the damage. Vitamin B6 prevents this buildup, thereby reducing the risk of heart attack. Pyridoxine lowers blood pressure and blood cholesterol levels and keeps blood platelets from sticking together. All of these properties work to keep heart disease at bay. - Benefits of Vitamin B6 

Some studies suggest that the vitamin B6-magnesium combination can also help attention deficit disorder, citing improvements in hyperactivity, hyperemotivity/aggressiveness and improved school attention. - Attention deficit hyperactivity disorders. Magnesium Research
