Whether you are vegan, vegeterian or omnivorous, how do you ensure you are eating a "balanced" meal?
In my quest to become "more vegan," I've discovered that my problem is that I'll eat a lot of one thing, e.g., I will happily eat raw kale for breakfast, lunch and dinner for a week. It might be healthy, but it's hardly a balanced meal. I admit that this is related to subpar grocery shopping habits--I ALWAYS buy the same one or two things.
Nutrition/fitness websites that I've surveyed are too general. You need more "calcium, iron, protein", etc, but surely that hardly covers the milligrams of other nutrients that are important to a body?
What rules do you go by when you are planning your next meal? Do you eat 5 colors a day? Is there a (vegan/vegetarian-oriented) nutrition book that you recommend? (I would really like a book that confirms I'm not damaging my health by seasonal consumption of certain nutrients, i.e., I am wild about grapefruit in the winter, and so my absorption of Vit C drops precipitously as soon as grapefruit is out of season and I move on to other things).
P.S. I'd like to avoid multi-vitamins.
