Question 3 [20]
3.1 The human body’s requirement for salt is more or less 2 to 8 grams per day. However,
studies have shown that people consume up to 30 grams per day. It is advisable to avoid
too much salt, because high sodium intakes correlate with high blood pressure. Carefully
jot down 7 short, easy-to-remember guidelines that you can share with patients with high
blood pressure to help them reduce their sodium intake. (10)
