I eat a bag of salad a day. Those huge family sized bags from Lidl and Aldi. I've just read that because the leaves are washed and gassed with chlorine that they have almost no nutritional value. It also said they contain far more pesticides and preservatives to keep the leaves looking fresh for longer. Then there's the plastic bag they come in, the water used to wash them, the carbon footprint or transport, etc 
It's almost impossible to eat healthy nowadays. I gave up almond milk because the industry is killing off the bees. All vegetables that don't cost a fortune are grown in artificial light and sprayed with round up apparently. On a positive note, if I have to start growing my own organic fruit and veg I'll finally lose weight as I can kill plants by just looking at them.
