For a client following a vegetarian lifestyle, which food choice is appropriate?

Tofu is a suitable food choice for a client following a vegetarian lifestyle. It is derived from soybeans and is a rich source of plant-based protein, making it an excellent alternative to meat for those who avoid animal products. Tofu also provides important nutrients such as iron and calcium, which can sometimes be more challenging to obtain in adequate amounts from a vegetarian diet.

Incorporating tofu can help ensure that individuals following a vegetarian lifestyle can meet their dietary needs while still adhering to their values regarding animal consumption. It can be easily prepared in various dishes, absorbing flavors well and offering versatility in cooking.

Other options like chicken, fish, and beef are animal products and do not fit within a vegetarian diet, therefore making them inappropriate choices for someone following a vegetarian lifestyle.
