Soya are beans, but like grain they are also seeds. Do you know what the difference is that makes grain allegedly a bad choice but beans benign?
That you would have to a Taoist I am not one I merely was pointing out that tofu was not invented to avoid meat but grains although some Taoists are vegetarians not all are.

Taoist generally adhere to the Yin Yang principle of balance.
Yin foods are believed to be cool and thought to moisten your body. Yang foods are believed to be warm and drying.
The yin or yang characteristics of a certain food have less to do with its actual temperature or moisture level than its purported energy properties and effects on your body.
"Cool" or yin foods are generally low in calories and high in potassium. They’re recommended in hot weather. "Hot" or yang foods tend to be higher in calories and sodium. They’re recommended in colder months to help warm your body.
Common yin foods include:
soy products, such as tofu and soybean sprouts
certain meats, such as crab and duck
fruit, such as watermelon and star fruit
vegetables, such as watercress, cucumbers, carrots, and cabbage
cold drinks and water
Common yang foods include:
most foods that are high in fat, protein, calories, and sodium
certain meats, such as chicken, pork, and beef
warm spices, such as cinnamon, nutmeg, and ginger
eggs, glutinous rice, sesame oil, bamboo, and mushrooms
alcoholic beverages
