If anyone has missed this. Thought it was interesting; I notice a lot of food with peas or potatoes as some of their main ingredients.
None of this makes sense to me. I reblogged that memo a while ago with some criticisms of the bullshit “study” that was done try to prove this, because they had so many variables that were unaccounted for.
Grains do not contain taurine. Why would it make a difference if the filler is peas or corn? Typically there’s less meat in a dog food containing grain, which would mean less taurine overall unless the manufacturer adds it in. Again, their only proof of this is a study with a very small sample size and so many variables that were just ignored. I’m curious to see if the FDA does an actual study on it and what their conclusions will be.
I almost feel like potentially the “diets” they are talking about are people trying to make their dogs vegetarian, in which case they would be substituted with a lot of pulses. The whole low taurine thing is a valid concern but yeah I cannot see what on earth that has to do with grain free food, since more meat means more taurine. Either this study is totally bogus, or they are burying the lead in a major way
@hesped some grain free foods substitute peas/lentils and potatoes in place of grain. The way I saw this explained was some protein like lamb is low in taurine so with foods that add a lot of legumes there ends up being a taurine deficiency. Peas and lentils can increase the protein content but doesn’t contain taurine like muscle meat does. Some companies are including a lot of peas/lentils as part of the protein content meaning less actual meat. The heart issues are being seen more in dog breeds that aren’t efficient in synthesizing their own taurine.
Anyway that’s my understanding of it. It’s being vaguely spread that grain free = heart issues but it’s a lot more specific than that.
I was comparing dog foods awhile back and Origin was looking the best in terms of meat content and very low peas/lentils/potatoes in comparison to say Canadian naturals and first mate. There is a formula you can use to calculate the amount of carbs in the food which can help tell how much “filler” is being added
100 – protein % – fat % – moisture % – ash % (use 6% if not listed) = carb %
Anyway that’s my understanding of it so far. Don’t know how reputable the info is I’ve been looking up but I’m trying to get a better idea. I haven’t looked into the effects of the vegetarian formulas but I think those supplement with taurine.
Someone was explaining it to me in that maybe some of these grain free alternative binders (peas/etc) are somehow inhibiting absorption of the taurine from protein sources in the food. Don’t know anything about the science behind that, but I was personally suspicious that this might ultimately be about vegan and vegetarian dog food—though the original bogus article citing the small study pointed a finger at any and all ‘ boutique’ natural pet foods (which is silly and just reeks of hills or royal canin bullshit).
Yeah I heard the same about the peas blocking absorption of the taurine but couldn’t find a source. I am suspicious on the way this is coming out, like it’s trying to scare people back into buying grain free foods. It seems very vague on saying grain free foods are bad, but aren’t specifying why or which ones (lower taurine protein such as lamb esp single protein formulas)
