Maintaining Health (Formerly Health and Efficiency)
by Rasmus Larssen Alsaker
About the author
Born in Norway in 1883, he later became a Norwegian-American physician and health writer. He is best remembered for popular books on food, digestion, fasting, exercise, and everyday health habits, written for general readers rather than specialists.
His work reflects an early preventive-health approach, arguing that many chronic troubles could be improved through changes in diet and lifestyle. Titles associated with him include Maintaining Health, Eating for Health and Efficiency, and books on the heart, rheumatism, and digestive complaints.
He died on June 14, 1960. Today, he is mainly of interest as a prolific historical figure in natural health writing, especially for readers curious about how ideas about nutrition and self-care were presented in the first half of the 20th century.
