Whether baking soda works or not, eating a healthy diet with lots of leafy greens is a proven way to reduce inflammation in the body. Getting the right amount of vitamin D is another. Eating health fats like Omega 3s helps. And engaging in moderate exercise, getting good sleep, and having good connection to family, friends, and nature also help reduce inflammation in various ways. And of course avoid sugar and most refined carbohydrates -- as well as most food additives. Example link: https://www.health.harvard.edu/staying-healthy/foods-that-fi...
Except you can do all that (have always done that) and still be struck down with run-away inflammation, and without being some obvious genetic outlier.
What you are describing is nowhere near the cure-all that unsymptomatic bystanders assume it is.
You may also get hit by a car or get struck by lightning. Nothing is a guaranteed cure-all but what the GP describes is probably a good idea for a lot of people.

For those with autoimmune disorders no amount of healthy diet is enough.
My only experience with this is for chronic metabolic acidosis due to renal failure (in a parent) - there are sodium bicarbonate tablets in 325 and 650mg. Taken multiple times a day. Somewhere around 1500-3000mg/day. Looks like this study was working with a single amount of 2g dissolved in 250mL.
I had suffered from dueodenul ulcers, and was hospitalized, almost died.
This was right before my 21st birthday, so afterwards, during that time in my life, I attended alot of parties, but my stomach would often sour (time of night, food, etc.).
I was not much of a drinker, but I would use baking soda at house parties when my stomach started to turn.
I would not do it daily, but 1 tsp dissolved in approx 6 oz of water as needed.
