Eating processed red meat, like bacon and sausages, is linked to a 16% higher dementia risk. This alarming finding highlights the importance of dietary choices in protecting cognitive function as we age.

N=133,000 over 40 year time period

Observational study so limitations may apply but the findings do hold after adjusting for a large list of factors I will quote here:

educational attainments, family history of dementia, menopausal status with hormone use status, total energy intake, regular antidepressant drug use, history of depression, BMI, moderate-to-vigorous physical activity, neighborhood SES [socioeconomic status], marital status, living arrangement, smoking status, histories of hypertension, diabetes, and hypercholesterolemia and intakes of sugar-sweetened beverages, fruits, vegetables, whole grains, poultry, fish, eggs, nuts and legumes, low-fat dairy products, high-fat dairy products, and alcohol

        Stupid question - are whole plant foods just fruit and veggies and nuts, or is it also stuff like nut milks, chickpea pasta, etc?

          When people say “whole” they’re referring to virtually any plant food that’s in it’s whole, ideally intact, form. For example in descending order:

          1. Farro is a whole grain. It’s a type of wheat, and it’s whole because all parts of the grain are still there - the bran, germ, and endosperm. This is the ideal kind of grain to eat - whole and intact.
          2. Whole wheat noodles are still a whole grain, but a bit less so because although all parts of the grain are still in it, it’s been broken down and reconstituted into a new form. The structure of plant foods in and of itself has health impacts.
          3. Whole wheat bread is still a whole grain, but quality can vary greatly depending on the ingredients and ways it gets processed. The vast majority of “whole wheat bread” is honestly dubious at best. Even more, since bread is less compressed than noodles, it digests more rapidly, and takes on properties that start to resemble refined grains more.
          4. Refined grains. Think white rice, white bread. Low fiber, low phytonutrients. These foods digest rapidly, lack important nutrients, and have a high glycemic load (high blood sugar spikes).

          Chickpea pasta would be comparable to number two on this list, so not bad. Store bought plant milks are not whole foods because the plant solids have been strained out. If you were to make a plant milk by, say, blending whole soy beans or almonds in water, that would be a whole food.
