Final answer:
To reduce lower esophageal sphincter pressure, Dan should avoid alcohol, caffeine, spicy foods, and citrus fruits.
Step-by-step explanation:
When teaching Dan, age 76, how to reduce his lower esophageal sphincter pressure, it is recommended to avoid substances like alcohol, caffeine, spicy foods, and citrus fruits. These foods and beverages tend to contribute to GERD (gastroesophageal reflux disease) and can increase the pressure in the lower esophageal sphincter, leading to symptoms like heartburn and acid reflux. Quitting smoking, losing weight, and practicing portion control can also help reduce pressure in the lower esophageal sphincter.
