Sweetener saccharin shows surprise power against antibiotic resistance

Of course not. But a kid raised on a high-sugar diet, particularly if reïnforced repetitively through habit, is going to have a tougher time eating healthy than someone who learned to see sugary drinks as a treat.

Alchohol isn't really good for you - statistically you will probably get away with reasonably low intake but the observational studies showing a benefit were most likely confounding variables - like studies where the 'non-drinkers' category contained those who had been alcoholics and were forced to stop drinking, or demographic distortions where moderate drinkers had much healthier lifestyles in other areas (exercise, access to healthcare, etc.) than heavy drinkers.

Coffee seems to be good for you, as long as it's only up to a few (3-4) a day, and as long as it's not affecting your sleep. But I have read the fines in methods like Turkish coffees could be somewhat harmful, whereas espresso is fine and paper filtered better. Sweetening it with sugar isn't great for you of course.

One that gets me is dairy and milk, I get the ethical concerns, and one can make an argument that it's not super 'natural' to take another species milk and to drink it after infancy, but that doesn't mean it's unhealthy (almost all medicines are 'unnatural' too, while some poisons are fully natural!). There's some evidence of milk/dairy being protective against bowel cancer for instance, and inconclusive evidence of harms so I do wince a bit at the plant-based milk alternatives (which are highly- or ultra-processed, if you do care about that kind of thing!) being so trendy.

No, isomaltulose(a.k.a Palatinose) is the best. Not very sweet, but it's literally just glucose and fructose connected differently, no other off-products or metabolic consequences, just a sweet carbohydrate with slow metabolism that doesn't cause cavities and is beneficial to the gut microbiota due to the slow release of sugar, just like a good resistant starch would.

It's not as sweet, low calorie, or inexpensive, but health-wise forget being harmless, it's outright better than almost all other carbs.

Guess it's all about the usage model..!!

This general weakness of the bacterial wall is something to be wary of given they didn’t study its effect on a wider range of important bacteria.

Throwing a lot of anything in your gut that can cause an imbalance, ir serious dybosis is a good reason to treat your stomach like a little fermenting aquarium whose bacteria and skin cells cycle every 3-5 days.
