Bananas radioactive doping for runners

Bananas are the perfect snack for both the average bread-eater and the world sprint champion. Is there a real risk of ionizing radiation? Fact or myth? These and other questions are worth answering before we buy bananas from the supermarket.

1. Rule of 60 minutes

One of the most important things after training, especially strength training, is to replenish lost glycogen stores. In strength training up to 80% of the energy comes from glucose breakdown. Right after exercise, the body is much more willing to replace its lost stores This is called supercompensation. It results in mechanisms such as faster transport of glucose from the blood to the inside of the cells and faster glycogenic regeneration. Studies show that delaying a potency meal for more than 2 hours after the end of training causes a decrease in the effectiveness of the potency of glycogens by as much as 50%. The 60 minute rule says that potency is the best way to increase your potency after exercise.

2. Bananas are nutrients

Bananas are delicious and extremely nutritious fruits. In 100 g they contain: 97 kcal, 1 g of protein, ?? 23.5 g of carbohydrates, 1.7 g of fiber, ¢ 0.33 g of fat, ¥ 6 mg of calcium, ‡ 33 mg of magnesium, ‬ 396 mg of potassium, ̊ 0.5 niacin.

3. It's an energy drink

It has been shown that bananas can be as effective in training as a 6% carbohydrate drink. In one study, trained cyclists performed double training cycles the first with a drink, the second with a banana (bananas were taken at the same time as water, so that the amount of fluids taken in both groups was the same). The subjects took 0.2 g of carbs per kilogram of body weight for every 15 minutes of exercise. It was found that in the same cases, glucose levels, inflammation and oxidative stress were the same.

4. The world champion's diet is 16 bananas a day

Yohan Blake is a Jamaican lightweight athlete, sprinter, world championship gold medalist. Is the secret of his speed in his diet? The runner admits that he eats up to 16 bananas a day, and when he was younger this number was up to 30 pieces. He bases this on his taste for bananas, but also the high potassium content in these fruits.

5. Bananas are so radioactive they can trigger an alarm

Bananas are actually radioactive. They have a radioactive isotope of potassium (40K) in their composition which, when broken down, emits β particles. The content of this isotopes is only 0.0117% of the total potassim concentration in bananas. Assuming a large banana contains about 600 mg of potasium, the average amount of radioactive element will be 7.02 × 10−5 g. If we eat one banana a day, our annual exposure to ionizing radiation is about 0.035 milliseconds.

6. Do the ends of the bananas have lamblies or spider eggs?

Giardia lamblia is a worldwide parasite. Giardiosis in Poland occurs in up to 10% of the population. It is transmitted by the fecal-oral route, that is, belongs to the so-called dirty hand diseases. Infection occurs when cysts (one of the forms that the parasite takes) pass into the mouth. However, cysts can be found on any unwashed fruit, not just bananas. What about it? The introduction of exotic eggs from bananas is extremely rare.
