Some plant alternatives have less protein and what they do have can come from soy and pea protein isolate which raises concerns among some dieticians.

一些植物替代品含有较少的蛋白质，它们所含的蛋白质可能来自大豆和豌豆分离蛋白，这引起了一些营养学家的关注。

They contain ingredients unfamiliar to domestic kitchens such as soy protein isolate (in cereal bars or shakes with added protein) and " mechanically separated meat" (turkey hotdogs, sausage rolls).

这些食物含有国内厨房不常见的原料，比如大豆分离蛋白(蛋白谷物棒或蛋白奶昔)与“机械分离肉”(火鸡热狗、香肠卷)。
