Yet originally you phrased it as if it were a general truth, so as to (intentionally or unintentionally) have the effect of misleading your fellow humans not born and raised or influenced by dietary patterns of your country, which is what my query was (is) all about.
Easy, meat has no fiber.
Western (read: American) diet consists of over consumption of meat, refined sugar, and processed grains, and woeful lack of vegetables, and lesser extent fruits.
If the value of Beyond Meat is "better for you, better for environment", the health benefits seem dubious at best, and environmentally, I don't know if anyone has compared the impact on a per-oz of beef vs per-oz of beyond meat--though the meat industry at scale has had serious negative impact on our environment (putting it mildly)
Most of us on the western diet, would do better to increase our consumption of veggies.
