Salt Preference is Linked to Hypertension and not to Aging

Area of Science:

• Nutrition Science
• Cardiovascular Health
• Dietary Habits

Background:

• Reducing dietary salt intake is crucial for managing hypertension.
• Seasoning is a potential strategy to decrease salt consumption.
• Limited research exists on how seasoning affects salt preference.

Purpose of the Study:

• To compare salt preference in bread among hypertensive and normotensive outpatients.
• To investigate if seasoning can alter salt preference in these groups.
• To assess the influence of age on salt preference in relation to hypertension.

Main Methods:

• 118 outpatients were divided into four groups: young/older hypertensive and young/older normotensive.
• Participants tasted bread samples with varying salt concentrations before and after seasoning.
• Blood pressure and urinary sodium/potassium excretion were measured.

Main Results:

• Hypertensive individuals showed a higher preference for saltier bread compared to normotensive individuals.
• Seasoning significantly reduced the preference for saltier bread in all groups, especially hypertensive individuals.
• Age did not significantly influence salt preference, but hypertension did.

Conclusions:

• Hypertension, not age, is linked to a higher preference for salt.
• Seasoned bread effectively reduced salt preference across all participant groups.
• Seasoning is a viable strategy to encourage lower salt consumption in diverse populations.
