You've got cinnamon as being okay, but some cinnamon contains coumarin, which is toxic to dogs (it's only really dangerous in large amounts, but smaller amounts can cause stomach issues). There are two types of cinnamon, Cassia and Ceylon - Cassia has relatively high amounts of coumarin, while Ceylon has virtually none.
For beef you say not to give it raw, but in many cases that's fine. You also say not to give human food as regular part of their diet, but feeding meat, vegetable and grains is often better than kibble.
You also say not to feed beef bones, but raw bones are fine - it's cooked bones that should be avoided (because cooking weakens them and can lead them to splinter).
If you're going to give this kind of health-related information, you need to do a better job and make sure what you're saying is accurate.
