A study from the Netherlands has just been published 1 which continues to pile up the evidence that plant-based diets help to prevent diabetes, while animal-based diets do quite the opposite.
The researchers start from the suggestion that vegan/vegetarian diets are claimed as being useful in reducing the risk of type 2 diabetes (T2D). But they consider that not enough is still not known about whether replacing an animal-based with a plant-based diet may be beneficial for prevention of T2D.
To establish this, they looked at data from the original 1991 prospective cohort Rotterdam Study 2 as well as from the subsequent follow-ups 3 and investigated whether: “…levels of adherence to a diet high in plant-based foods and low in animal-based foods is associated with insulin resistance, prediabetes, and T2D“.
There were 6798 participants in this prospective population-based cohort study in the Netherlands. They collected dietary intake data via questionnaires. Information on insulin resistance was derived from homeostasis models (HOMA-IR), and both prediabetes and T2D data were collected from general practitioners’ records, pharmacies’ databases, and from follow-up examinations in their research centre until 2012.
During the 5.7 and 7.3 years of follow-up, they documented 928 prediabetes cases and 642 T2D cases.
After they adjusted for sociodemographic/lifestyle factors, they found that a plant-based diet was associated with the following:
- lower risk of prediabetes
- significantly lower risk of insulin resistance
- significantly lower risk of developing T2D
They concluded that: “…a more plant-based and less animal-based diet may lower risk of insulin resistance, prediabetes and T2D.”
In addition, they consider that their findings strengthen recent dietary recommendations for populations to adopt a more plant-based diet.
Although we’ve already looked at aspects of diabetes in relation to diet 4 5 , I think it’s always worth mentioning new research in this area as it appears – invariably, it seems, appearing to be in favour of the plant-based and against meat-based diets.
And this isn’t just a matter of what you see – it’s also what you don’t see: you don’t see research stating the opposite!
Indeed, instead of peer-reviewed published research data, all we really get is Paleo Propaganda…
Where’s the beef?!
