What is the evidence behind salt sensitivity?

At DNAffit, we have a strict inclusion protocol to evaluate whether a gene will be included in our reports. Each gene must have a minimum of 3-peer reviewed studies in humans demonstrating the effect, there must be a consensus on that effect, and that effect must be modifiable through an environmental and lifestyle change.

Below is a sample of our evidence base for salt sensitivity:
