You probably like sweets?
Monkeys and cavemen also looked for sweet food in the woods, like berries, fruits,
and honey.
That’s because if it’s sweet - it is most likely edible!
Sour food can mean that the fruit is unripe.
And bitter food can mean that it is poisonous.

Most people think that there are four tastes: sweet, sour, bitter, and salty.
But there is a fifth taste too. It was discovered a hundred years ago.
It’s called a japanese word “umami”.
This taste tells you food is nourishing.
Meat, mushrooms, and walnuts, all have that taste.
Soy sauce gives that taste to any food.
