In this thread or elsewhere? I’m scrolling up and not seeing any source. The Google image search turned up a bunch of charts. Any one image in particular? I didn’t see anything obviously related to your statement:
Which is what I was referring to.
Let me quote from the full text:
Long-term restriction of dietary sodium intake has a clinically relevant impact on cardiovascular disease, with reduction in risk being estimated to amount to up to 25% , as reinforced recently . We demonstrated that HDL-C decreased by 0.05 mmol/l in response to sodium restriction. A meta-analysis of prospective observational studies has demonstrated that mortality from ischemic heart disease is 33% higher for each 0.33 mmol/l lower HDL-C . Extrapolating these data  to the present findings and assuming that the decrease in HDL-C is sustained with long-term sodium restriction could translate into a modest 5% increase in risk, which seems unlikely to outweigh the risk reduction attributable to long-term low sodium intake.
Long-term restriction of sodium reduces the risk of cardiovascular disease by up to 25%. The decreased HDL may increase risk by 5%, assuming the short-term decrease holds true over time (it was only a one-week study). Their results are also possibly only applicable to healthy young men, since as they say:
Obviously, the exclusion criteria applied make that our current findings do not necessarily hold true for hypertensive, overweight or diabetic populations and for women.
Soylent 1.5/2.0 are also not in the low range of sodium intake in that study, except at low caloric intakes (unlikely in healthy young men, but that data isn’t available since they weren’t on controlled diets), and would usually fall between the low and high ranges. The high sodium group (228 ± 77 mmol) should be 5,244 ± 1,771 mg at 23 mg per mmol, while the low sodium group (36 ± 27 mmol) is 828 ± 621 mg. Even at 2000 calories, Soylent 2.0 is already at 1500 mg (above the low range, which caps out at 1449 mg). At 3000 calories, 2.0 is up to 2250 mg. This is assuming 100% Soylent 2.0, since once we add other foods sodium intake becomes an unknown quantity. Soylent 1.5 is similar: 1520 mg per 2000 calories, 2280 mg per 3000 calories.
