Aside from supplements, what are some reputable companies whose purview is nutrition?
Allow me to rephrase and ask a similar question in OP’s stead:
In the nutrition space, aside from companies who focus on supplements to improving nutrition, are there companies that take another route in improving nutrition and how do they do it?
For example: using regenerative organic farming to improve density, or Huel creating an artificial food formula with all nutrients needed.
>whose purview is nutrition?
You’d have to be more specific.
Coca Cola is a reputable company that claims that soda can be part of a responsible diet.
There are diet plans - Jenny Craig, Weight Watchers, Slim-Fast, etc… some of it’s good advice, some of it’s garbage.
There are service providers - like Noom and Keto-Mojo - that may or may not work for any given individual but could work wonders for another for entirely different reasons.
What are you looking for?
The “companies” (sellers) at local farmer’s markets.
Every national/international corporation is suspect, and they can change for better or for worse at any time. So if you’re looking for a brand to trust, I don’t see the point.
