Dieting has changed significantly over the last 50 years. In the 1970s, people consumed more vegetables and fruits than they do now. In the 1980s, the rise of working women and the microwave changed the food landscape in the UK, with meals based on pasta becoming more popular than the traditional meat, potato, and two vegetables. The 1980s also saw the rise of the Beverly Hills Diet, which was based on the idea that certain foods should be combined and others avoided. The 1990s saw a shift towards the Mediterranean diet, with its emphasis on healthy fats, whole grains, lean meats, and fresh vegetables. In the US, the 1990s saw a peak in sugar consumption, with an average of 90.2 pounds of added caloric sweeteners consumed per person per year. The turn of the 21st century saw a shift in public opinion, with fats being embraced and carbohydrates avoided. The last 50 years have also seen a proliferation of fad diets, with Weight Watchers and the Atkins Diet gaining popularity in the 1960s and 1970s, respectively.

What You'll Learn
Diets are more diverse
The diversity of diets has increased over the past 50 years. This is due to several factors, including the globalization of food supplies, the influence of technology and science, and changing consumer preferences.
Globalization has played a significant role in diversifying diets. The spread of crops to new countries has led to a greater variety of foods being consumed worldwide. For example, the Cuban diet became more diverse during the Período Especial in the early 1990s, with an increase in the consumption of soybean and palm oil as alternatives to sunflower oil, which had previously been imported from the Soviet Union. Similarly, the fall of communism in Albania disrupted food supplies, leading to greater total quantities of food and a more wheat-dominated diet.
Advancements in technology and science have also contributed to the diversity of diets. The development of new food processing techniques, such as the use of refined sugars, additives, and preservatives, has transformed the way we eat. Additionally, the rise of smartphone usage has impacted our dietary habits. The convenience of fast food delivery apps and the influence of health and fitness influencers have led to a rise in plant-based diets and "clean eating" movements.
Changing consumer preferences have further diversified diets. People are increasingly concerned about the environmental and ethical implications of their food choices, leading to a decline in dairy consumption and a rise in plant-based alternatives. Health trends, such as the preference for semi-skimmed milk over whole milk and the popularity of superfoods like avocados, have also influenced dietary choices.
The diversity of diets can also be attributed to economic development and urbanization. The growth of international trade and transportation methods has made a wider range of foods accessible to consumers worldwide. This has resulted in an increase in the similarity of food supplies across different countries, with more countries reflecting a global average diet.
Lastly, political unrest can also lead to greater diversity in diets. Disruptions in food supplies during periods of political instability can cause people to adopt new dietary habits and incorporate different types of crops or foods.

People eat more food
People today eat more food than they did 50 years ago. Food prices have dropped so significantly that, on average, people spend a mere 7% of their budget on food—less than in any other nation. This is down from 1919, when people spent more than three times that percentage. Improvements in technology and transportation mean that people can now easily access a wide variety of foods from around the world. For example, someone in Kansas can now buy pineapples from the tropics and farmed salmon from the Atlantic in the same mid-winter grocery trip.
The abundance of food has led to overeating. Food historian Dr. Ken Albala notes that the past century is the first time "when a sizable percentage of the population can actually overeat. That's never been the case in history before." This is reflected in rising obesity rates. Three-quarters of Americans are overweight, and 6 out of 10 suffer from chronic illnesses such as diabetes, heart disease, asthma, and hepatitis.
The rise of fast food has also contributed to people eating more. The fast-food boom has led to increasing rates of obesity and diabetes. In addition, the rise of smartphones has made fast food even more accessible, with fast food delivery available at our fingertips.
People's diets have also become more diverse in the last 50 years. Crops have migrated and are now grown in new countries, so people are eating foods that were not part of their diet before. For example, Americans now eat more salsa than ketchup, and ramen is as familiar as Campbell's tomato soup. The growth of Indian and Chinese communities in Britain introduced people to new cuisines, and dishes like Spaghetti Bolognese became popular after people started taking overseas holidays.

Vegetables are less nutritious
Over the last 50 years, diets have become more diverse, with the average person consuming more fruits and fewer vegetables. The fast-food boom and the rise of smartphones have also contributed to changing dietary habits. While the average life expectancy has increased, there are concerns about the nutritional content of our food due to large-scale farming practices.
The nutritional value of vegetables has declined over the years, with studies showing significant decreases in important nutrients. A 2004 study by Donald Davis and scientists at the University of Texas found that 43 foods, mostly vegetables, had lower nutrient levels between the mid and late 20th century. Calcium in green beans, vitamin A in asparagus, and iron in broccoli stalks were notably reduced. Similar studies have documented declines in other nutrients, such as magnesium, zinc, and vitamins B-6 and E.
This decline in nutritional content is attributed to agricultural practices focused on improving traits like size, growth rate, and pest resistance rather than nutrition. Soil depletion is also a contributing factor, as crops grown in depleted soil lack the richness in vitamins and minerals found in crops from decades ago.
To address this issue, some scientists propose biofortification, a process of putting nutrients directly into seeds to enhance their nutritional value. However, biofortification has limitations, as it typically focuses on one or two nutrients, while nutrient decline affects multiple nutrients simultaneously. Additionally, the accessibility of biofortified seeds is currently limited due to supply and cost constraints.
While large-scale farming methods have contributed to a decrease in the nutritional value of vegetables, it is important to note that vegetables are still rich sources of various nutrients and offer numerous health benefits.

Fast food is more popular
Over the last 50 years, diets have changed drastically due to various factors, including advances in technology and science, while others are a matter of convenience. One of the most notable changes is the popularity of fast food. While fast-food restaurants with drive-through windows were already common in the 1950s, the fast-food boom has intensified in recent decades. Americans, for instance, are consuming large amounts of cheap and unhealthy burgers and fries from over 50,000 fast-food restaurants across the country. This trend is not limited to the United States, as global dietary patterns are becoming increasingly similar.
The rise of smartphone usage in the 2010s played a significant role in the popularity of fast food. With just a few taps on their phones, people could easily order and have fast food delivered right to their doorsteps. This convenience, coupled with the allure of cheap and tasty meals, made fast food an appealing option for many. The busy lifestyles of people also contributed to the preference for quick and convenient dining options.
The fast-food industry has been quick to adapt to changing consumer preferences and trends. The introduction of the so-called "fast-casual" restaurant concept, which offers freshly prepared food with higher-quality ingredients, has blurred the lines between fast food and traditional dining. Chains like Panera Bread, Shake Shack, and Chipotle have revolutionized the industry by providing a middle ground between fast food and casual dining.
In addition to convenience and taste, the marketing strategies of the sugar industry have also played a role in the popularity of fast food. Since the 1960s, the sugar industry has funded research to downplay the health risks of sugar and shift the blame to fats. As a result, sugar consumption has skyrocketed, with Americans consuming about 152 pounds of sugar per person today, far exceeding the recommended amount. High-fructose corn syrup, which was first developed in 1957, has also made its way into the American diet, contributing to the sweet appeal of many fast-food options.
While the popularity of fast food has grown, it is important to note that it coexists with a rise in health consciousness. The availability and preference for plant-based diets, "clean eating" movements, and exotic superfoods reflect a growing awareness of the impact of dietary choices on personal health and the environment. However, the convenience and affordability of fast food continue to make it a popular choice for many, shaping the dietary landscape of the past 50 years.

People eat less milk
Dieting has changed significantly over the past 50 years, with a shift towards more processed and ultra-processed foods, sugar, industrial seed oils, and poultry, and a decrease in butter, lard, whole milk, fresh fruits, and vegetables. The rise of the smartphone has also impacted our eating habits, with fast food delivery becoming easily accessible and "clean eating" movements gaining traction.
One notable change in dietary habits over the past 50 years is the decrease in milk consumption. People are drinking less milk, especially whole milk, and opting for more cheese and yogurt instead. This trend is observed in both adults and children, with each new generation consuming less fluid milk than the previous one.
Several factors contribute to this decline in milk consumption. Firstly, there is an increasing variety of beverage choices available in supermarkets, restaurants, and other food outlets. People now have more options to choose from, including plant-based milk alternatives such as almond, rice, coconut, oat, and hemp milk. These alternatives are often perceived as healthier or more environmentally friendly options compared to dairy milk.
Additionally, the rise in popularity of sugar-sweetened beverages, such as soft drinks and juice drinks, has likely contributed to the decrease in milk consumption. These sugary drinks may be seen as more convenient and tasty alternatives to milk, especially for children and teenagers.
While milk consumption has decreased, overall dairy consumption has changed. The consumption of cheese and yogurt has increased significantly in some countries, such as the United States. People are consuming more cheese and yogurt, often offsetting the decline in milk consumption. However, despite these increases, about 90% of the U.S. population does not meet the Dietary Guidelines' dairy recommendations.
In summary, people are drinking less milk, especially whole milk, over the past 50 years. This trend is influenced by a variety of factors, including an increasing number of beverage choices, the popularity of sugar-sweetened drinks, and shifting preferences towards plant-based alternatives. While milk consumption has declined, overall dairy consumption has been impacted by the rising popularity of cheese and yogurt in some countries.
