It's easier to start with what I don't eat- sweets and dairy, and then move in.
I eat plenty of rice, legumes, seafood, vegetables and fruit.
I usually have a glass of wine a day, and probably 5 cups of tea.
Seasonal adjustments? I eat more fresh fruits and vegetables in the summer, from my parents garden and the farmers market. In the winter I eat more meat and I bake more bread.
I take a calcium supplement because I like having bones and don't consume dairy. Otherwise, I think I'm probably rather properly balanced dietarily!
