Sport best lettuce to use?

[sexanoe]

i have been using red leaf for the last couple of years, just wanted to know if there was a more nutritious one

I doubt any one is much better than the other. Just have them all for the sake of variety, that's what I do. Romaine, Red Leaf, Boston, etc...

I would think the deeper red/green the lettuce is the more nutritional it is. Like romaine and baby greens are superier to boston or iceberg.
