It's probably not the Glutamate in MSG that is bad for you, it's the Sodium.
That statement doesn't quite hit the mark, Keith. While it's true that sodium plays a role in high blood pressure and cardiovascular risks, the key factor—as I've already mentioned—is always the total amount.
Monosodium glutamate contains significantly less sodium than NaCl (table salt), so that with skillful use and substitution of NaCl with MSG, one can actually reduce sodium intake while maintaining or even improving the flavor.
At the same time, glutamate itself is not a purely inorganic “foreign substance,” but rather an amino acid produced naturally by the body that plays a central role in metabolism and particularly in the brain, which means that the body can generally handle it without any problems.
Here, too, when it comes to carbohydrates, many things are simply lumped together, which would be better considered in a more nuanced way.
If one wants to take the health context seriously, it is worth examining the overall structure of one’s diet, noting that the quality of carbohydrates plays a significantly greater role than the question of whether MSG is present in any food.
Monosaccharides and rapidly available, highly processed carbohydrates, such as rice and refined flours, lead to rapid spikes in blood sugar, which is metabolically unfavorable in the long term, whereas complex polysaccharides, dietary fiber, and soluble fiber, such found in oats, have a completely different effect, as they are metabolized more slowly and simultaneously have a positive influence on the gut flora.
Dietary fibers, such as Beta-glucane, which are found in oats and barley, for example, have been shown to help lower cholesterol levels and stabilize blood sugar, demonstrating that the real drivers of health lie much more in the overall composition of the diet than in individual substances.
In this context, it also becomes clear that many discussions about supposedly problematic ingredients miss the mark in practice because they ignore the actual levers of control. Anyone who wants to design a sensible diet can, for example, easily make their own vegetable broth by drying, grinding, and using fresh vegetables, herbs, and spices, thereby maintaining control over both the salt content and the overall composition.
In many cases, this also eliminates the need to rely on industrially produced products like Maggi or other highly processed meat and chicken broths in large quantities, which are often characterized primarily by salt, fat, and additives.
What matters is the overall composition of the diet—which sources of carbohydrates, proteins, and unsaturated fats dominate, the ratio of omega-6 to omega-3, etc.—and the extent to which processed products play a role.
A healthy diet should be balanced, natural, as fresh as possible, varied, and tailored to your body’s specific needs.
ASR is always very focused on measurable facts in audio technology; what I sometimes read here about food chemistry and metabolism reminds me of audio voodoo websites.
