What was the name of the health institution opened in 1866?

The correct answer is the Battle Creek Sanitarium, which opened in 1866. This institution was founded by John Harvey Kellogg and became a cornerstone of the health reform movement associated with the Seventh-day Adventist Church. The sanitarium emphasized a holistic approach to health, integrating diet, exercise, and spiritual well-being, which was in line with the church’s teachings on healthful living.

The Health Reform Institute, while an important part of the health movement, was established later and is often confused with the Battle Creek Sanitarium due to their similar missions. The other options, such as the Health Improvement Center and the Medical Missionary Institute, although related to health reform and education in their respective contexts, do not refer to the specific institution that opened in 1866. Understanding the significance of the Battle Creek Sanitarium in the advancement of health practices and its historical impact on the Adventist community is essential in appreciating its role in the broader health movement of that era.
