Why is pet food so confusing? Are corn, raw, and brands really good?
Hello! All great questions and comments - and you're right, there's a lot of conflicting information out there regarding food. Some of the information you're going to find is based on personal preference or a value bias. Corn is a good source of digestible carbs, fatty acids, and protein - but these things are better digested in dogs than in cats (who are obligate carnivores), and some people prefer to minimize grains, so those people might state corn is "bad".... in my opinion, the focus on grains is based more on trends in human nutrition than evidence-based pet nutrition. Statements regarding what pet foods are "good" vs "bad" will also come from personal preference...your vet can probably explain what made them state that Purina is better than Merrick, and another vet might have their own input on the matter. I do personally like both Purina and Hills because I find their products consistent, reliable, and I like that those companies put a lot of their profits back into nutrition research to work on creating good foods - but that doesn't mean they're the only good foods out there.
Raw food is another hot topic. I have worked extensively with dog mushers, and raw meat is a very common component to their food - and I'm fine with that. However, I also have a degree in Public Health, and know that raw foods increase the likelihood of foodborne illness such as salmonella both in the pets themselves, and in the humans who are in contact with them. So, again, there are going to be different sides to the conversation.
It's confusing when there's conflicting information! Try to sort through what's based on research and evidence, and what is based on the personal opinions and biases of the speaker. Good luck! Hope this helps.
