Peeling carrots is not necessary  from a nutritional standpoint,  

as the skin and just beneath it  contain valuable nutrients and fiber.

However, there are reasons why you  might choose to peel them. The skin  

can sometimes have a bitter taste  or be tough, which peeling removes.

Additionally, peeling can eliminate any residual  dirt or pesticides on non-organic carrots,  

even though washing them thoroughly can  also effectively reduce these residues.

If you prefer to keep the peel for its  nutritional benefits, scrubbing carrots  

well under running water with a brush is  a good practice to clean them thoroughly.

For organic carrots, washing  might be more appealing as  

they are grown with fewer chemical pesticides.

Ultimately, whether to peel carrots comes down  

to personal preference and  the intended use in recipes.

Eating them with the peel on  maximizes their nutritional value,  

while peeling can enhance texture  and remove any unwanted residues.
