Low sodium salt: the smarter way to flavour your food

If you've been told to cut back on sodium, your first instinct may be to reach for a low sodium salt substitute. But here's what most labels don't tell you: simply swapping salts rarely solves the flavour problem. The real answer lies in understanding how your taste buds perceive saltiness — and that's where Discover MSG comes in.

What is low sodium salt?

Low sodium salt typically replaces a portion of sodium chloride (regular table salt) with potassium chloride. While this reduces overall sodium content, potassium chloride often leaves a bitter or metallic aftertaste — making food feel less satisfying. Many people end up using more of it to compensate, which defeats the purpose entirely.

Is monosodium glutamate healthy?

Yes — and decades of research support this. Monosodium glutamate Healthy (MSG) contains roughly 60% less sodium than table salt by weight. Because it delivers intense savoury depth at smaller quantities, you can season your food with significantly less total sodium without any loss in taste satisfaction. The U.S. Food and Drug Administration (FDA) classifies MSG as "generally recognised as safe" (GRAS), and major health organisations worldwide share this position.



Natural sources of MSG — it's already in your food

One of the most common misconceptions is that MSG is an artificial additive. In reality, glutamate — the core compound in MSG — occurs naturally in many everyday foods.

The natural source of MSG and the manufactured form are chemically identical. Your body cannot tell the difference — because there is none.

MSG umami — the taste that makes food satisfying

Umami is the fifth basic taste — alongside sweet, sour, salty, and bitter. It is described as a deep, savoury, mouth-coating richness that makes food feel complete. MSG is the purest delivery mechanism for MSG umami flavour, activating glutamate receptors on the tongue to create that lasting, satisfying sensation. Crucially, umami can enhance the perception of saltiness — meaning a small amount of MSG can make your food taste saltier than it actually is, helping you use less low sodium salt overall.

The Discover MSG approach

At Discover MSG, we believe the best low sodium salt strategy is not just substitution — it's intelligent seasoning. By combining a reduced amount of regular salt with a small quantity of MSG, you can cut your sodium intake by up to 40% while keeping your meals just as flavourful. This approach is backed by peer-reviewed research and is increasingly recommended by dietitians working with patients managing blood pressure and cardiovascular health.

Quick tip from Discover MSG

Replace half your regular salt with a small pinch of MSG. Taste before adding more. Most people are surprised that less salt is needed — because umami is already doing the heavy lifting.

Conclusion

Low sodium salt alternatives have their place, but they work best when paired with a smarter understanding of flavour. MSG is healthy, naturally occurring, and the most effective way to add umami depth to any dish — all while keeping your sodium levels in check. Whether you're cooking for a health-conscious family or managing a specific dietary goal, Discover MSG gives you the science and the tools to eat better without eating bland.
