> I'm French (and incidentally a doctor,and my post is not judgemental in any way, this is not the point). Everytime I travel to the USA, I'm puzzled by how difficult it is to "eat normally" (= by my own standards).

As biologist with a background in Agriculture and Culinary: they exist, most farm to table restaurants in the US just have a small footprint in overall ecosystem. I spent most of my culinary career within them, ranging from Vegan to vegetation to seasonal based omnivore option. I also worked and ran kitchens in Agrotourisms in Europe and I'm familiar benefits with the Mediterranean diet, Spain having now surpassing Japan in Life expectancy, and diet is a significant contributor to it.

> I think sugar is the main problem (not fat) and I'm not convinced calory count is key. We did not evolved to eat processed sugar, which is not easily found naturally in the environment.

Agreed, and even that is not always so cut and clear as having extra CNV of the amalayse gene (like I do) can be super beneficial, which leans to the need of the Biohacker space (of which I'm a part of and is comprised mainly of many dissatisfied Health Scientists) to play with diet and the epigenetic effects of it, as that has been woefuly neglected for decades in Medicine and Scientific journals but a mainstay in the Biohacker community that has become mainstream due to influencers.

As a kid I never understood the allure of sweets/desserts because of the CNV in my saliva is already breaking down the sugars in my mouth and makes super sweet things always taste a bit like the after taste of bitter chocolate or coffee--none of which I like. I always liked eating fruit, especially tart or sour ones more as a desert and only found out later in Life why that was. the study of how a palette is formed is a very interesting and entirely negated study in my opinion.

> This implies to know/learn how to cook (not so hard but this is easier when the local/family culture allowed you to learn passively).

Agreed! The best thing to do is to learn to cook with local, fresh organic products and help solidify a local food supply chain and relationship with your local farmers! This has a compound effect throughout the entire community and many communities are open vacant lots to community garden spaces.

> It looks like this is hard to do in the USA: you don't easily find, for example, yogurt without sugar added. (Or I didn't look at the right place, once again this is not judgemental).

It's there, its just found at higher end stores and outlets, ironically it costs more to deliver a product with less sugar and additives; but even Walmart has been a big player in the Organic produce Market. There is one next to my gym and I often went in to buy a pre-workout snack or a kombucha and there was always something I could eat without spiking my glucose levels.

> Generally speaking, it is easy to find online high-level cooking courses, but hard to learn the basics of how to cook your onions or tomatoes in different ways in everyday life, or make an healthy meal with what's left in the fridge; this could be interesting to have.

Agreed. Its an undervalued art and craft, in Boulder (one of the most concentrated 'foodie' places in the entire US) there are classes offered via a business that offers Learning Kitchen experiences where professional chefs from the surrounding area are commissioned on a topic/recipe/menu and teach paying members of the community on how to do things via interactive cooking.

Its a very cool model that I think should be expanded on. I'd love to be able to work with some of my old team members in the Industry especially if it could help offset my expenses and help me fund other projects in my Life; online learning could be a bridge or a primer, but cooking is ultimately a craft you learn by repeated instruction and correcting hand positioning (re-enforced with lots of cuts, burns, scrapes) that makes it more like going to the gym than watching a lecture on a subject.

You can learn online, I know I did watching Michelin Star chefs on Saturday Kitchen on the BBC before making the return into culinary in Europe, having only ever worked in catering while I was attending University as it inspired me to experiment with different techniques. I'm now retired from Kitchens but want I want to create a food docu-series, as I feel now is a critical time in Restaurants after having been so impacted due to COVID, that many may not make it.

> ban every processed food, sauce, appetizer.... If you would not eat a spoon of every single ingredient of some food, don't eat it. - ban all added sugar, except (real) honey in reasonable proportions.

I'm not for banning anything, just using it in moderation and having people have a solid understanding on what it does to you metabolically and its impacts on health. Japanese and Italian cuisine are the two pillars my culinary repertoire and sugar is a vital component of Japanese recipes that simply cannot be substituted. I've tried stevia and honey but it just doesn't work, a proper tare is sweetned with sugar not just for taste and lush sheen and gloss when used to grill, but also as the precursors for the bacteria to ferment that takes place over years to give it a unique and umami loaded taste that defines Japanese cuisine.

And pasta and bread, carbohydrates, are just processed long-linked sugars and I can never give those up despite seeing and personally experienced the benefits of keto and carnivore diets in my friends.

I'd throw including intermittent fasting and meditation/yoga in that equation as well and you have a solid foundation for how to be healthier and more productive in Life that I found via Biohacking methods, cooking and farming professionally.

I also have the genetics for longevity on both sides of my family: my grandparents all made it to their late 90s, and my grandmother on my maternal side hit 99.7 before passing due to non health related issues, so I'm hoping that with this information guiding my behaviour I can make it to 150 years of age.
