The Claim
In high-income countries, the primary source of dietary sodium is processed foods and meals consumed outside the home, whereas in low- and middle-income countries, dietary sodium is primarily derived from salt added during home cooking or from condiments such as soy sauce and fish sauce.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In rich countries, most salt in our food comes from packaged snacks and restaurant meals, but in poorer countries, people usually add salt themselves while cooking or use salty sauces like soy sauce.
