I had a slight bike accident and have just had 7 stitches today...?

I unfortunately fell on concrete and know have a number of abrasions on my left forearm, hands, knee and right shoulder. I also have a large abrasion on the right of my face and a cut above and running into my eyebrows - almost everywhere.

I went to A&E and they stitched my eyebrows - 7 stitches.
I also have a number of abrasions. I have washed them with warm water and antiseptics.

What should I do in order to keep my abrasion wounds clean?
Is it possible to reduce scarring by eating certain foods?
How can I reduce scarring in the long run?

just keep the wounds clean and dry. Tea Tree oil and lavender oil are great ante septics. Put a few drops of them in water and bathe.
glad you were not more seriously injured.

take vitamin c supplements if you like.
Increase fresh fruit and veg intake. Eat chicken, fish and beef. You don;t need to go over the top but just eat healthily.
