Children’s science issues reflect on what is the world’s most unhealthy vegetable.
According to Professor Mikael Fogelholm, it may well be coconut if toxic vegetables are left out of the bills.
The abundant saturated fat in coconut raises blood LDL cholesterol and increases the risk of cardiovascular disease.
Coconut is a rare exception in vegetables. Usually they are very healthy and important sources of vitamins.
What is the most unhealthy vegetable in the world?

Vegetables The vegetables, roots, berries and fruits used as foods are generally calculated. Some of the fungi are very toxic and thus unhealthy.
Even for edible mushrooms, for example, the ear sponge is deadly toxic if it is not prepared properly.
Even in Finland, the ear fungi must definitely be cooked twice in plenty of water at least five minutes at a time. Boiled mushrooms must also be rinsed well after both soups.
The toxicity of food sponges has not been much compared, but untreated ear fungus is certainly one of the most toxic mushrooms in the world. When cooked properly, your ear sponge is healthy food!
Of non -toxic vegetables, coconut is a good candidate to be the most unhealthy vegetable in the world. The coconut’s nutritional content is special because it has an exceptionally high level of fat.
The unhealthy is due to the fact that the coconut fat is saturated in composition, that is, hard. Most of the fats in the plants are unsatisfactory. This is recognized by the fact that they are running at room temperature.
Hard fat, for example, increases the concentration of unhealthy LDL cholesterol in the blood, one of the biggest factors that increase cardiovascular disease. The coconut should not be eaten in food except occasionally.
Coconut is a rare exception, as vegetables are almost invariably very healthy. They are very important sources of vitamins and minerals.

We do something all the time when we are resting, as muscle is already needed to breathe.
Can you do anything?
Elsa Kuokkanen, 9
While we live We do something all the time. Even breathing is to do because it requires muscles and affects the outside world by moving the air.
We do not even notice much of our activities, but we work a bit like autopilot. Fortunately, you don’t have to plan every step, but you can think of more interesting and comfortable things.
Sometimes it is good to be idle so that you do not do anything special, but, for example, dreams of a hammock, walks in a familiar environment, or does something else that doesn’t have to work. Jouty is a great way to relax and organize thoughts. Even then, the brain works briskly and a lot of things to mind popping up.
Better than doing in a hurry to focus on important things. It helps if you can be idle from time to time.

The highest place in the earth’s Himalayas mountains can also be considered the most lumpy.
What is the most even point in the world? What about lumpy?
Siiri Vuorela, 5
Terrestrial The smoothest areas of the surface are located in the depths of the oceans. About 40 percent of the bottom of the oceans, almost half, is a deep sea level.
That plateau consists of sediment, that is, landed and stratified there, which can be up to five kilometers deep. The sediment is a loose substance, which makes it very smooth according to the gravity of the earth.
The ground plains are also very flat. The most even area above sea level is Salar de Uyun’s plain in Bolivia.
The area is over 10,000 square kilometers, or one million hectares. Its surface consists of a smooth dried salt. In the entire plateau area, the height varies less than a meter.
The most even song in our solar system is Jupiter’s Moon Europa, the highest points of which are only a few hundred meters high ridges.
If, on the other hand, at the world’s most even point, it means the most smooth substance, a good candidate is graphene, which is a very thin mesh and plain substance.
Also a viable option is the substance called Helium4. It does not repeat so easily the irregularities of other materials when they touched it like graphene. However, the super -mounted helium4 would only form a top -level surface very close to the absolute zero point, about -273 Celsius temperature and under high pressure.
The Himalayan Mountain is the highest place on the surface of the globe and can also be considered the most lumpy. The most uneven points in Himalayan are located in the Nepalese area. The highest peak is Mount Everest, about 8850 meters.
When you think about the whole universe, Mars is a very lumpy celestial body. At least the other planets of the solar system are not to compete with it. For example, Mars has the highest mountain and the deepest canyon in the solar system.
A good candidate for the lump is a prickly nanohiukkanen, developed at the University of Michigan in the United States.

The number of people who have lived on Earth over time can only be roughly estimated. The current estimate is over 110 billion.
How many people have lived on the earth?
Enni Rantala, 8
Human life Accurate calculation requires uniform statistics. Based on the statistics of the United Nations, the United Nations and the pre -Federation of Nations, it is known that after 1920, about 12 billion people have emerged, of which 10 billion after 1945.
From the beginning of the era to 1920, it was estimated that about 45-50 billion people were born, and during the 10,000 -year period, about 40 billion people.
In the past, there were estimated to about 10-15 billion people. They were hunter-collectors, that is, lived directly from nature.
Thus, over 110 billion people have lived roughly on Earth. Efforts have been made to outline the number of people through old writings, cities, tombs, archaeological discoveries and inheritance factors, and by evaluating the effects of diseases, disappearances and wars.
The difficulty of responding is how humanity is defined. Europeans, in particular, have indications of crossing with Neanderthal people, and there is no certainty whether a person, or Homo Sapiens, is over 200,000 or even 300,000 years old.

Correction 7.3. 7.52am: Corrected point for the treatment of ear fungi. Quick bursting, or cooking in hot water, is not enough, as was initially stated, but the ear fungi must be cooked twice in plenty of water at least five minutes at a time, and the fungi must also be rinsed well. Correction 7.3. 11:18 pm: The word burst completely removed from the response and replaced it by handling and cooking.
