While previous studies have found a link between red meat consumption and type 2 diabetes risk, this study, which analyzed a large number of type 2 diabetes cases among participants being followed for an extended period of years, adds a greater level of certainty about the association.
Type 2 diabetes rates are increasing rapidly in the U.S. and worldwide. This is concerning not only because the disease is a serious burden, but it also is a major risk factor for cardiovascular and kidney disease, cancer, and dementia.
For this study, the researchers analyzed health data from 216,695 participants from the Nurses’ Health Study (NHS), NHS II, and Health Professionals Follow-up Study (HPFS). Diet was assessed with food frequency questionnaires every two to four years, for up to 36 years. During this time, more than 22,000 participants developed type 2 diabetes.
Key Research Outcomes
The researchers found that consumption of red meat, including processed and unprocessed red meat, was strongly associated with increased risk of type 2 diabetes. Participants who ate the most red meat had a 62% higher risk of developing type 2 diabetes compared to those who ate the least. Every additional daily serving of processed red meat was associated with a 46% greater risk of developing type 2 diabetes and every additional daily serving of unprocessed red meat was associated with a 24% greater risk.
The researchers also estimated the potential effects of substituting one daily serving of red meat for another protein source. They found that substituting a serving of nuts and legumes was associated with a 30% lower risk of type 2 diabetes, and substituting a serving of dairy products was associated with a 22% lower risk.
@ddnomad @BuddyTheBeefalo Omega-3 is an EFA, not an amino acid. It also isn't an issue if you get fats in their whole form (i.e. flax seeds instead of flax oil) as far as I understand.
The only actual deficiency that is present in a balanced whole foods plant based diet is B12, and that is a product of modern sanitation practices (dairy has it btw b/c cows are fortified with it as I understand it). Easily satisfied with a Vit B12 supplement or nutritional yeast.
My bad, "I'm not a scientist" bit me hard here lol, though I did read that if you get your omega-3 from plant sources (linolenic acid) its absorption rate is extremely low comparing to sources like salmon.
Regarding supplementation, I feel like having to do that because of inherent issues with your diet is somewhat of a dirty hack (I do take some supplements though, so I'm not gonna pretend like it is not an option).
@ddnomad The only supplements I take are B12 and D3, and many omnivores are deficient in those as well. Lack of B12 stems from modern sanitation practices and lack of D3 stems from people not going outside as much. It's compensating for changes to lifestyle and our food system, not for something lacking in our diet per se.
@ddnomad @BuddyTheBeefalo Vitamin D is the other one, but that's true for *everyone* (it's why both dairy and plant-based milks are fortified with D3) and there are, again, supplements if necessary (this one is necessary for pretty much everyone not living near the equator).
Otherwise, nutritionally, a WFPB diet is pretty much the most balanced and nutritious (esp for long-term health) diet one can have.
@ddnomad @BuddyTheBeefalo Dairy consumption is both very recent (evolutionarily) and was historically limited to a few places (even today, the vast majority of the world is lactose-intolerant).
