The American diet is a pressing issue, with poor diet now one of the leading causes of death in the country. The Standard American Diet (SAD) is high in processed foods, fast foods, added sugars, and sodium, and low in whole grains, legumes, nuts, seeds, fruits and vegetables. This has resulted in a range of health issues, from weight gain and obesity to chronic illnesses such as cardiovascular disease, cancer, and diabetes. While there have been efforts to address this issue, such as the MyPlate guidelines and the integration of food and nutrition into healthcare, more needs to be done to improve the American diet and reduce the associated health risks.

What You'll Learn
The high cost of healthy food
The perception of healthy food being more costly is a critical factor in dietary choices. According to Carlson & Frazao (2012), people may choose less nutritious foods to save money, compromising their health. This is supported by a study that found adhering to dietary guidelines would cost a family of four $1,000 to $1,200 per month, significantly higher than the average food expenditure. As a result, many, especially those on limited budgets, find it challenging to eat healthily.
The financial implications of unhealthy eating extend beyond grocery costs. Obesity and chronic diseases, such as cardiovascular issues and diabetes, are more prevalent in individuals with poor diets. These conditions lead to higher medical expenses, with obese individuals incurring $1,500 more in annual medical costs on average. Therefore, while choosing healthy foods may seem expensive initially, the long-term savings in healthcare costs could offset this.
To address these concerns, various policies have been proposed. One suggestion is to tax snack foods and sugar-sweetened beverages, making them less affordable and potentially encouraging the purchase of healthier options. Conversely, some advocate for reducing the cost of nutritious foods through government initiatives. Research supports this approach, with a study finding that people consumed 25% more fruits and vegetables when their cost was reduced by 50%.
While the cost of healthy food is a significant challenge, it is not the only factor contributing to America's unhealthy eating habits. The abundance and convenience of junk food, as well as a lack of knowledge about healthy cooking and dietary choices, also play a role. Addressing these issues will require a multifaceted approach, including educational initiatives and structural changes to make healthy food more accessible and affordable.

The convenience of fast food
Fast food is a staple of the American diet, with over 20% of meals being eaten in cars. It is a convenient option for busy individuals and families, offering speed, accessibility, and ease of eating on the go. In today's fast-paced world, time is precious, and many people opt for fast food due to its quick service and convenience. Shift workers, college students, and travelers often choose fast food to fit meals into their busy schedules.
Fast food is also affordable. The large scale of many fast-food restaurants, often franchises, allows them to purchase ingredients in bulk at lower prices, reducing their costs per unit. Minimal service, with food served at the counter or through drive-throughs, further decreases expenses. Efficient cooking techniques, such as standardized recipes, pre-cooked ingredients, and specialized equipment, enable fast-food restaurants to produce and serve large quantities of food quickly and at a low cost.
However, the convenience and affordability of fast food come at a cost to health. Fast food is typically highly processed and contains high levels of saturated fat, sodium, sugar, and refined carbohydrates, which are linked to serious health issues. These include heart disease, high cholesterol, weight gain, obesity, and diabetes. Prolonged consumption of fast food can also lead to insulin resistance and digestive issues.
While fast food may be convenient and affordable, it is essential to recognize its potential negative impact on health. Making small changes, such as choosing whole grain bread over white bread or opting for healthier fast-food alternatives, can be a step towards improving dietary choices and leading a healthier life.

The abundance of ultra-processed food
The issue is not just limited to fast-food chains but also grocery stores, which offer a wide variety of processed food options that are often cheaper and more accessible than fresh, nutritious foods like fruits, vegetables, and lean meats. The availability and affordability of healthy food options are crucial factors in promoting a balanced diet. The high cost of nutritious foods can strain tight budgets, making it challenging for individuals to make healthier choices.
The Standard American Diet (SAD) is characterized by its high content of processed foods, fast foods, added sugars, and sodium. This diet has been linked to various health issues, including obesity, chronic illnesses, and cardiovascular disease. The overconsumption of discretionary calories, or non-essential calories from sources such as solid fats, saturated and trans fats, and added sugars, is a particular concern. These "SoFAS" foods, as termed by the Dietary Guidelines Advisory Committee (DGAC), contribute to excess calorie intake, which can lead to weight gain and increase the risk of diet-related chronic diseases.
To address this issue, it is essential to recognize the role of convenience and accessibility in food choices. In today's fast-paced world, many people prioritize convenience over the quality of their meals. The availability of ultra-processed foods that are quick and easy to prepare or purchase has contributed to the decline in home-cooked meals. Additionally, advancements in technology and transportation have made it possible to access a wide variety of foods from different parts of the world, further contributing to the abundance of ultra-processed options.
To promote healthier eating habits, it is crucial to make nutritious foods more accessible and affordable. This can include initiatives such as providing healthy meals and groceries to patients, especially those at risk for diet-related illnesses, and integrating food and nutrition into healthcare. Additionally, educational programs and campaigns can empower individuals to make informed choices and understand the impact of their dietary decisions on their overall health.

The negative health effects of the American diet
The Standard American Diet (SAD) is quite literally killing Americans. The average American diet consists of excess sodium, saturated fat, refined grains, and calories from solid fats and added sugars. It is also severely lacking in nutritious foods like fresh fruits, vegetables, whole grains, legumes, nuts, seeds, and lean meats. Poor diet is predominantly associated with weight gain and obesity, but it can also contribute to the development of many diseases, including:
- Cardiac dysfunction and cardiovascular disease: A Western diet has been shown to impair cardiac function in mice, and it has also been linked to elevated fasting insulin levels and lower insulin sensitivity in rats. These results suggest that a Western diet may contribute to the development of insulin resistance, a precursor to type 2 diabetes. Additionally, the American Heart Association reports 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 increase in caloric consumption has been linked to higher rates of obesity and overweight individuals, with almost 35% of adults in the US being obese, and an estimated 70% being overweight.
- Asthma: Studies have shown that while the Western diet does not cause asthma, it can worsen the severity of the condition.
- Mental health issues: Eating a diet high in fat and sugar can be associated with a greater incidence of depression and depressive symptoms, impaired learning and memory, and an increased risk of developing α-synuclein clumps, which are a hallmark of Parkinson's disease.
- High blood pressure and high cholesterol: The CDC notes that these conditions are caused by consuming too much salt and are the leading causes of heart disease and stroke.
- Other diseases: The American diet has also been linked to an increased risk of cancer, chronic illness, stroke, diabetes, and fatty liver disease.

The role of nutrition in healthcare
Nutrition plays a critical role in healthcare, and the American diet has been labelled a "national disgrace" by some experts. Poor diet is now one of the leading causes of death in America, even more so than smoking. It is a significant contributor to weight gain, obesity, and chronic illnesses such as cardiovascular disease, stroke, diabetes, cancer, and fatty liver disease. The average American diet consists of excess sodium, saturated fat, refined grains, and calories from solid fats, added sugars, and sweeteners.
The Standard American Diet (SAD) is characterised by an overabundance of processed foods, fast foods, added sugars, and sodium. This diet lacks sufficient fruits, vegetables, whole grains, legumes, nuts, and seeds. The issue is not just limited to fast-food restaurants but also extends to grocery stores, where nutritious foods are often more expensive than packaged, processed alternatives. This makes it challenging for people to make healthier choices, especially when combined with the convenience and affordability of readily available, calorie-dense foods.
To address these concerns, there is a growing movement to integrate nutrition into healthcare. This includes providing healthy meals and groceries to patients to help prevent or manage diet-related illnesses. For example, prescriptions for fruits and vegetables can encourage healthier eating habits and improve diet quality. Additionally, the Affordable Care Act mandates that diet counselling be covered by insurers as a preventive measure for those at higher risk of chronic diseases.
Furthermore, the White House nutrition conference has proposed several ideas to tackle unhealthy eating habits, including the creation of a national director of food and nutrition to streamline efforts. The USDA has also made efforts to promote healthy eating by introducing MyPlate, which replaces the old food pyramid. While this is a step in the right direction, more work needs to be done to educate the public about the impact of their dietary choices and to encourage a cultural shift towards a healthier lifestyle.
