Who wrote such an unrefined article?

Your version is unrefined, amateurish, sloppy.

He's a bit unrefined, that's all.

But he was mean and he was coarse and unrefined

Fresh vegetables, raspberries, pita with mare's milk, germinated cereals ...

How many of you can actually tell wheat apart from other cereals?

Foods rich in vitamin E include dark green, leafy vegetables, beans, nuts and whole grain cereals.

In the lower part, cereals are grown, and in the shallows, fish and seaweed are cultivated.

And meat consumption in Southeast Asia and China in particular is what drives the prices of cereals.

And these are things like whole foods, or unrefined carbs fruits, vegetables, whole wheat flour, brown rice, in their natural forms, are rich in fiber.

It would help enormously if we could move more towards nuts and less towards cereals cos they are much more sustainable because they grow on trees.

And the ultimate may be, but it doesn't apply to cereals, that we have entirely closed ecosystems the horticultural systems right at the top left hand corner.

In other words we want to achieve a natural cycle, where the city gets back fish from the shallows, cereals from the fields, vegetables from the plant factory.

At this time, I hardly managed to do mazes on the back of my cereals box, so, how do you want me to find my way in a game like that!
