I miss the SpO2 sensor on my old S5. It used to work up until a couple years ago when S Health took out the functionality.
My wife did not feel well last year and thought her pulse was going up. I figure I'd reassure her quickly (or notice an issue) with my Note 8.
Unbeknowst to me, some samsung update put the hardware functionality behind some health app that wanted to setup a tracking profile and two factor authentication and my email and my phone and name and details and preferences and goals and 12 point health plan and whatnot.
By the end I was the one with anxiety attack. I'm still livid when I think about it. I'm not a violent or profane man but... I have some thoughts reserved for people who planned, approved and implemented that. Not all evil is big evil. Little evil is evil too (Note for all fellow software engineers here :)
I think I picked up a dedicated unit finger pulse oximeter for like $20.
FWIU Apple Watch is one product with FDA approval as a medical device (ECG Electrocardiogram) for detection of AFib Atrial Fibrillation and Parkinsons.

I did buy the separate $20 sp02 / pulse monitor after that episode. She has an apple watch now but I of course have zero confidence / will not trust the kindness of corporate strangers again to allow me access to my own hardware.
i.e., A vegetarian diet?
https://en.wikipedia.org/wiki/Veganism#Nutrients_and_potenti... :
> Vegan diets tend to be high in dietary fiber, folate, vitamins C and E, potassium, magnesium, and unsaturated fats.[34] However, consuming no animal products increases the risk of deficiencies of vitamins B12 and D, calcium, iron, and omega-3 fatty acids. [34][264]
> The American Academy of Nutrition and Dietetics states that special attention may be necessary to ensure that a vegan diet will provide adequate amounts of vitamin B12, omega-3 fatty acids, vitamin D, calcium, iodine, iron, and zinc. It also states that concern that vegans and vegan athletes may not consume an adequate amount and quality of protein is unsubstantiated. [265]
FWIU, high-red-meat diet outcomes are probably on average worse.
