Evolution of NutritionHuman understanding of nutrition has evolved exponentially over the past century. Until the beginning of the 20th century, there was little interest in nutrition research. Almost all nutritional knowledge of the time came from the philosophies and opinions of immigrants. America had little knowledge while other countries had begun to invest in nutritional research. Part of the reason this topic began to gain momentum at the time was the fear of falling behind other nations. Additionally, the lifestyle of the average citizen was different. The majority of America was rural farmland, so they were physically active. The general consensus among the population was that a good diet led to good mental and physical health. It was around this time that jobs such as nutritionists and personal trainers began to appear. Times were changing and nutrition was impacting every aspect of life. The evolution of nutrition throughout the 20th century affected the works of writers of the time. Nutrition was considered an unimportant and unnecessary area of ​​study. When this view began to change and the field of nutrition began to grow, a new career opportunity as a nutritionist emerged. Scientists have begun to study the importance and effects of the foods they have eaten for hundreds of years. One of the most common ideologies was that eating fresh fruits and green vegetables was not worth it. Many considered these foods beneficial, but inferior to meat products like chicken or steak. The problem was that meat products were much more expensive and fewer people could afford to eat them regularly. Additionally, fruits and vegetables were relatively inexpensive given the abundance of the paper's lifespan. Finally, the Internet revolutionized the world to such an extent that scientific articles, videos and other publications containing information were immediately accessible. The Internet has allowed millions of writers to flourish and billions of people to read their works. Changes in nutrition over the past century have revolutionized lifestyles, allowing writers an endless amount of possible topics and methods of discussion.
