Since the doctor's recommendation. Kale seems to have slightly more nutrients, but, IMO, at to great a cost too taste.

The kale taste can be mitigated somewhat with a mixture of lemon juice, olive oil, salt, pepper and sesame oil. I do this with spicy arugula too as I often find the taste overpowering.

Ah that makes sense. Still, I stand by my shock. Going to kale before spinach is just nuts (barring pressure from a doctor who doesn't care about your culinary experiences).

Have you tried cooking it though? Kale is one of the greatest stir fry ingredients

I had the misfortune of working at a company that chose to get us lunches from Zesty. I endured more varieties of kale preparation (and avocado which I also dislike unless made into guacamole) in a month than in my entire previous life. So many things were great about that job, but I was actually dreading lunch on most days.

I found it to be the other way around, spinach tastes gross and kale is rather neutral. Were you cooking it?
