For instance, you might swap out olive oil for a lot of different kinds of plant oils. In Asian diets soybean oil has historically been one of many dominant oils, used for making ready stir-fried dishes with numerous greens and nuts. The obtainable fruits may additionally be completely different, and tofu is a broadly consumed plant-protein supply.

One instance the place we are able to get into bother is consuming an excessive amount of spinach, which has well being advantages however can even trigger kidney stones, presumably as a result of its excessive content material of oxalate. Within the US weight loss program, once we encourage consumption of inexperienced leafy greens, folks suppose this overwhelmingly means spinach.
