> This is an important insight from this research: cutting out beef and dairy (by substituting chicken, eggs, fish or plant-based food) has a much larger impact than eliminating chicken or fish.
My intuition is that this harm reduction is surprisingly doable for most omnivores, because it doesn't require going full vegan. Or going on a harm reduction meal plan on, say, all weekdays would make 80% of the difference.
Eliminating all the meats as options for core components of dishes all at once is a radical and major change.
Eliminating just a couple of them, ie beef or red meat, getting used to it and probably learning a couple veggie main dishes to replace the variety makes the next step easier.
Then cut back on a next meat or dairy item once the first step became normal. Repeat.
This worked for me, and at the start I didn’t even think I’d go all the way. I just wanted to stop eating red meat since it seemed the least efficient.
