Yohan Blake Eats 16 Bananas A Day

In 2011, Jamaican sprinter Yohan Blake ran the second fastest 200 meter sprint ever.

He says he eats 16 bananas a day to support his training:  
Sixteen bananas supplies 6760 mg potassium, 21 g protein, 431 g carbohydrate, 6 g fat, and 1680 kcal.  Here's the essential amino acid content of 16 bananas in grams and percentage of daily requirements:
Here's the vitamin content:
They provide more than 100% of the RDIs for B2, B5, B6, and vitamin C, just shy of 100% for folate, and 50% for B1. Finally, here's the mineral content: They supply more than 100% of the RDI for copper, magnesium, manganese, and potassium, more than 50% for iron (male requirements) and phosphorus, and more than 25% for zinc and selenium. Bananas also contain a significant amount of serotonin [1].  Connell et al reported feeding subjects 12 bananas daily:
"None of the subjects developed symptoms which could not be attributed to increased bulk alone, even though four of them ate 12 bananas daily for six days in addition to their normal diet...Most of them experienced a sensation of satiety from overeating, but none of them complained of diarrhoea, urgency, colic, or borborygmi." [2]
In male rats, a water extract of banana root "stimulated the normal functioning of the testes and exhibited both androgenic and anabolic properties." [3]  I have not found any research suggesting that the fruit has the same ability. Alcohol extracts of banana leaf apparently have efficient antibacterial activity against multi-drug resistant nosocomial infection causing pathogens. [4]

So - what say you about Michael Phelps and his diet?

http://blogs.wsj.com/health/2008/08/13/the-michael-phelps-diet-dont-try-it-at-home/

Breakfast: Three fried-egg sandwiches loaded with cheese, lettuce, tomatoes, fried onions and mayonnaise. Two cups of coffee. One five-egg omelet. One bowl of grits. Three slices of French toast topped with powdered sugar. Three chocolate-chip pancakes.

Lunch: One pound of enriched pasta. Two large ham and cheese sandwiches with mayo on white bread. Energy drinks packing 1,000 calories.

Dinner: One pound of pasta. An entire pizza. More energy drinks.

Phelps’ diet – which involves ingesting 4,000 calories every time he sits down for a meal – resembles that of a reckless overeater rather than an Olympian.

Phelps lends a new spin to the phrase “Breakfast of Champions” by starting off his day by eating three fried-egg sandwiches loaded with cheese, lettuce, tomatoes, fried onions and mayonnaise.

He follows that up with two cups of coffee, a five-egg omelet, a bowl of grits, three slices of French toast topped with powdered sugar and three chocolate-chip pancakes.

At lunch, Phelps gobbles up a pound of enriched pasta and two large ham and cheese sandwiches slathered with mayo on white bread – capping off the meal by chugging about 1,000 calories worth of energy drinks.

For dinner, Phelps really loads up on the carbs – what he needs to give him plenty of energy for his five-hours-a-day, six-days-a-week regimen – with a pound of pasta and an entire pizza.

He washes all that down with another 1,000 calories worth of energy drinks.

The michael phelps "diet" is an urban myth disputed by phelps himself.

He says he eats red bananas, which are smaller than our bananas, and probably different nutritionally.
