Separately from this study, here's an interesting opinion piece by John Ioannidis titled "The Challenge of Reforming Nutritional Epidemiologic Research", published in JAMA 2018:

Good thing I drink hazelnut coffee while eating eggs and bacon! It cancels out right?

		You're joking, but that's probably the right strategy: make sure to enjoy things on both sides of the aisle, so you don't have to worry about which side adds, and which removes, years. And then don't fret about it. Aside from that, I'd love to know how each of those items affects life quality. Living long is only a life goal up to a certain age, and from what I've seen around me, that age is very rarely 90.

these things are 100% true. I eat one hazelnut per hour and have lived already 230 years.
