Raising Sodium Recommendation

A recent meta-analysis suggests that <3g/day is actually worse than consuming 4-5g of sodium each day. This held true for people without hypertension and for people with hypertension. People with hypertension had worse outcomes if they consumed >7g/day, but actually the worst outcomes at <3g/day, and best outcome with 4-5g. People without hypertension did not have worse outcomes at 4-5g or >7g/day, but did at <3g/day.

The AHA’s main contention is the possibility of confounding factors; that sick people or unhealthy diets are related to <3g/day sodium intake and those are the cause. However the results of the meta-analysis remain significant when researchers control for past cardiovascular disease, which makes the confounding factors argument somewhat weaker.

What do we think about this?


Old news. This has already been discussed on this forum.

It may be new news because it adds more evidence that <3g per day is actually harmful, and compounding evidence should eventually lead to change. Current recommendations are built significantly on 1. the proven fact that sodium intake increases blood pressure and 2. higher blood pressure is correlated with more cardiac risk. 1 may be proven but 2 is a correlation, and as with some blood pressure lowering medications we’ve learned changing blood pressure directly is not always helpful and may be harmful. The whole point of following this logic was that low sodium intake should lower cardiac risk, but according to this meta-analysis it actually increases risk even more than high intake.

Another significant reason for recommendations is based on how much sodium is excreted in sweat, but as noted in the last thread that rises and lowers with sodium intake and may not be relevant to health outcomes.

What I want to know, is this good enough evidence to justify increasing Soylent’s sodium content? I think so, at least up from 1500mg even if they don’t take it to >3000mg.


There are some users who both need a low-sodium diet and who still struggle to limit the sodium in their non-soylent diet portion to levels that work for them. Adding sodium to soylent would make their eating choices more difficult.

For those of us (like me!) who need more sodium, it’s easy to add salt. Even 100% soylent users drink additional water; adding salt to their water is easy (and tasty!).
