High salt intake is a risk factor for osteoporosis because excess dietary sodium promotes urinary calcium loss, leading to calcium loss from bone and therefore decreased bone density.

Hypertension is an important risk factor for kidney disease, but dietary sodium has other damaging effects on the kidneys. High salt intake drives the production of oxygen radicals, leading to oxidative stress in kidney tissue.

Excess dietary salt is most notorious for increasing blood pressure. Americans have a 90 percent lifetime probability of developing high blood pressure - so even if your blood pressure is normal now, if you continue to eat the typical American diet, you will be at risk.

Your future health can be predicted by the nutrient density of your diet.

Resting metabolic rate is largely genetically determined, but our calorie intake has an effect as well.

Our studies show they do reduce subsequent intake in the meal. If your salad is high in calorie density, it's worse. You don't compensate later.
