Ya but... Very low salt also means poor Hydrochloric Acid in stomach = poor digestion/nutrition.
DASH works for some body/metabolism types. Should not be considered a one-size-fits all plan. Way too high in grains for many types. Paleo/anti-inflammatory diet is a strong alternative.
Low carb will lose weight. Heart will be happier.
