What's really normalized is metabolic syndrome. 88% of adult americans have some degree of metabolic dysfunction. High blood pressure, obesity and other ailments are very often a direct result of that. So much so, that the 'normal' range of indicators such as uric acid has been revised and adjusted over the years, because "normal" people had higher levels and still appeared to be fine. Thankfully, we are starting to question that (eg. https://pubmed.ncbi.nlm.nih.gov/24867507/)
First order of business for anyone watching their blood pressure creeping up over the years (even more so if A1C, triglycerides, liver enzymes and uric acid are rising too): cut sugar in all forms. Not just the sugar you personally add to food, not only what's specified as 'added sugar', but all food containing sugar - which is basically all ultra processed foods. It does include sliced bread which is easily broken down into sugar( and is often laced with additional sugar, check ingredients). Leave your sugar 'allowance' to be used by a reasonable amount of fruits.
That may not reverse the problem (although, in my case, it did) but should help tremendously.
No, first order of business is consulting your doctor and/or a nutritionist and otherwise adhering to common sense of having a reasonably balanced nutritional diet.
If your first order of business is taking random advice from the intertubez, you have bigger problems than high blood pressure.
In most places, any bozo can claim to be a nutritionist. From what I can tell, a large proportion of them are deranged crackpots.
So, no. Absolutely do not consult a self-described nutritionist.
