Obviously, we cannot know everything in life. Not far away, in the world of food and drink, there are still many secrets that you may not even notice. Here are just a few of them.
Many people have the misconception that the darker the apple, the sweeter it is. However, the truth is that the color of an apple’s skin does not indicate whether it is sweet or not. For example, the Red Delicious apple has the darkest red color but is less sweet than the lighter Fuji apple – which is considered the sweetest apple in the world today.
Biologically, eggplant is a berry and its seeds contain nicotine at a concentration of about 100 nanograms per gram of eggplant. That is, to consume the same amount of nicotine as a cigarette, you need to eat about 20 pounds (more than 9kg) of eggplant. It is known that, in addition to eggplant, tomatoes, potatoes and bell peppers also contain very little levels of this substance.
There are more than 1,000 varieties of bananas grown around the world today, and science has proven that this fruit contains the radioactive element Potassium-40.

Cashews are in the same family as ivy and poison sumac, which means that cashews contain a chemical irritant called anacardic acid. However, this substance is only found in the shell of the cashew nut. That is why cashews are often roasted, then the shell must be removed to eat.
Basically, fresh pineapple contains bromelain , a proteolytic enzyme that acts on your tongue, cheeks, and lips.
