I think the longer anyone waits, the more the program will improve and be more beneficial for a greater number. I can see it "evolving" and changing every week. They are actively using the biometric data of everyone who is enrolled. They got a big boost during COVID because they had a big COVID tracking and notification program. They most recently did the "Poop" study - they surveyed hundreds of thousands of people about poop habits and used app data to compare to general respondents/those not using the app. The foods I am eating that get high scores (including meals and recipes - it will take any internet recipe and "score" it for you - some score great) include MANY that I didn't eat before, because my IBS was so bad and they would set it off. I now suspect that my IBS symptoms were the result of gut microbes who love fructose or "fructans" - contained in the foods in the low FODMAP diet that everyone with IBS is told to eat. It was either a battle between the "good" and "bad" ones or a reaction of my body to the microbes that love the sugar (does not matter where it comes from, does include fake sugar like sugar-free gum and candy). Whatever it was - it's gone now. I've eaten them all, and the only food that bothered me a bit was extremely ripe, super sweet cantaloupe. But that was 2 hours of distress, not 3-4 days of being laid up with unbearable cramps. So, the BASICS of this, how I am eating, are exactly what my friend Diane, the professional nutritionist, said she and her husband eat. One fundamental is - we do not typically eat enough fiber. It also isn't contained in a lot of the foods we typically eat and even "leafy greens" don't have as much as we really should have. There's a couple of foods that I had avoided that do have good fiber: beans and whole grains - like steel cut oats or whole wheat berries. Now I eat those and use flax and bran. ALL GOOD - it plays an important role in so many ways. I see very good effects from eating these foods I avoided before due to too much gluten (grains), eating the wrong type (rolled oats vs. the delightful steel cut 'gruel' type), or IBS - brussels sprouts etc. I could list how much better I feel for ages - mentally, physically, energy, cognitive, but right now I am avoiding boring, tedious, seemingly endless work before we leave on kayak trip ... My friend Diane the nutritionist says Zoe is using real science but she feels the microbiome part is "mumbo jumbo" right now because it is so limited. It's probably true - they are just matching patterns without a real true understanding of which microbe does what.
