Paper: [Plant-Based Dietary Patterns and Risk of Alzheimer Disease and Related Dementias in the Multiethnic Cohort Study | Neurology](https://www.neurology.org/doi/10.1212/WNL.0000000000214916)
I’m 44 and most of my diet was sweets and anything that was on the table. I was in good shape and felt ok too.
Had a scare a few weeks ago and since then I’ve cut out sweets completely and I’m eating more fruit, vegetables and upped my fibre intake.
I feel like a new person. Mentally I’m a lot happier, physically I’m absolutely flying through any task.
Diet is a massive part of how you feel. I wouldn’t have believed it but the evidence, even after a few weeks is there.
What are the benefit to grains that aren’t a part of greens?
I’m now in my 70s – is it too late for me?
What’s particularly interesting about this study is that it compared different plant based diets, not comparing plant based versus non-plant based.
They divided plant based diets into „healthful“ and „unhealthful“ groups for the purpose of the study, and found the results positive for the healthful group.
In the conclusion they mention that abstaining from low-quality plant-based foods was especially notable.
Not in France. We have at least 4 times higher levels of cadmium than in most other countries, and cadmiun is known to cause Alzheimer amongst other things. Whole grains is less healthy than non whole grains here.
Most mornings I include a fruit smoothie made with soy or oat milk, apple, mixed fruit (usually pineapple, cantaloupe, honeydew, grapes and strawberry) and frozen mixed berries (black, blue and raspberries) I have about six to eight ounces, does this seem healthy or too sugary? Being a „Smoothie“ its the whole fruit and not just the juice.
