All products made by branded people may be healthier or may not be healthier
Changing to herbal tea yes it’s good option
Changing to protein bars yes good but I prefer natural home made than brand made
Meals also basically u can change ur lifestyle in a healthier way but rather depending on branded outside packed ,it’s good to depend on home food
And all plants don’t give all types of nutrient .
people having pure plant based can get vit
b12 deficiency leads to megaloblastic anemia ,neuritis and many more ..
But people should take good homemade healthier food rather taking supplements ..
