The Standard American Diet (SAD) is a modern dietary pattern that is high in carbohydrates, saturated fats, refined grains, and calories from solid fats and added sugars. It is characterized by a high consumption of processed and fast food, which are often high in sodium, sugar, and unhealthy oils. This diet has been linked to various health issues, including obesity, cardiovascular disease, diabetes, and cancer. Poor diet and sedentary lifestyles have led to high rates of overweight and obesity in the US, with nearly 40% of adults considered obese. While the SAD may be convenient, it lacks essential nutrients and contributes to a range of chronic illnesses.

What You'll Learn
Excess calories, saturated fats, added sugars, and sodium
The average American diet is often associated with excess, particularly in calories, saturated fats, trans fats, added sugars, and sodium. Obesity, cardiovascular disease, type 2 diabetes, and certain types of cancers are the health risks affecting a large number of Americans and are strongly associated with diet.
Excess Calories
According to the USDA, the daily per capita intake of calories increased by 617 between 1970 and 2008. The three largest contributors to this increase were added fats and oils, flour and cereal products, and caloric sweeteners. Caloric sweeteners, or added sugars, include all refined sugars, corn sweeteners, honey, and edible syrups. The discretionary calorie allowance is the balance of calories remaining in a person's energy allowance after accounting for those consumed when meeting recommended nutrient intakes through healthy foods. A high intake of added sugars or fats has the potential to contribute to the overconsumption of discretionary calories by Americans.
Saturated Fats
Saturated fats are naturally present in animal fats but can also be made from unsaturated fats through the process of hydrogenation. They are found in butter, cheese, red meat, other animal-based foods, and tropical oils. Saturated fats can raise the level of LDL (bad) cholesterol in the blood, increasing the risk of heart disease and stroke. The American Heart Association recommends limiting saturated fats to less than 6% of total calories.
Added Sugars
Added sugars include refined sugars, corn sweeteners, honey, and edible syrups. Sugar-sweetened beverages, such as soda, contain high amounts of added sugars and can contribute to excess caloric intake and weight gain, especially in children and adolescents. The American Heart Association recommends that most American women consume no more than 100 calories per day from added sugars (about 6 teaspoons of sugar), while men should limit their intake to no more than 150 calories per day (about 9 teaspoons).
Sodium
High blood pressure is a common health issue in the United States, affecting about half of the adult population. Excess sodium intake is linked to high blood pressure, and the average person consumes more sodium than is recommended for a healthy diet. The National High Blood Pressure Education Program recommends no more than 2,300 milligrams of sodium per day, with an ideal intake of only 1,500 milligrams.

Lack of fruits and vegetables
The American diet is often associated with excess, particularly in calories, saturated fats, trans fats, added sugars, and sodium. Poor diets and sedentary lifestyles have led to high rates of obesity, being overweight, and diet-related chronic diseases, including cardiovascular disease, hypertension, and diabetes. According to a 2010 report from the National Cancer Institute, three out of four Americans don't eat a single piece of fruit in a given day, and nearly nine out of ten don't reach the minimum recommended daily intake of vegetables.
The CDC reported that in 2015, only 9% of adults met the intake recommendations for vegetables, and only 12% met the recommendations for fruit. These numbers vary slightly from state to state, with Washington, D.C., having the highest fruit consumption and Alaska leading in vegetable intake. In contrast, West Virginia had the lowest compliance, with only 7.3% and 5.8% of people meeting the guidelines for fruit and vegetable consumption, respectively.
The lack of fruits and vegetables in the American diet is concerning, as these foods are essential sources of nutrients and contribute to a reduced risk of chronic diseases. A diet rich in fruits and vegetables can help prevent diabetes, heart disease, and certain types of cancer. However, the cost of fresh produce, lack of time to cook, cultural barriers, and limited access to healthy options are some of the challenges Americans face in incorporating more fruits and vegetables into their diets.
The USDA's crop subsidies also play a role in this issue. They primarily support crops like wheat, soy, and corn, which are used in many junk food products, giving these highly processed foods an unfair advantage over more nutritious options. Nevertheless, there are efforts to address this imbalance. For example, programs that provide vouchers for fresh produce and initiatives to make healthy options more affordable for lower-income individuals are positive steps towards improving the overall health of the nation.
In conclusion, while the American diet may be convenient and suited to the fast-paced lifestyle of many Americans, it falls short in terms of nutritional value due to the lack of fruits and vegetables. This deficiency has significant health implications and contributes to the high rates of diet-related diseases in the country. Addressing this issue requires a multi-faceted approach that considers cost, accessibility, and education to empower Americans to make healthier food choices.

High consumption of processed foods
The Standard American Diet (SAD) is often skewed towards protein and refined grains, while lacking fruits and vegetables. In fact, a 2010 report from the National Cancer Institute found that three out of four Americans don't eat a single piece of fruit in a given day, and almost nine out of ten don't reach the minimum recommended daily intake of vegetables.
The SAD diet is also packed with processed foods, with around 60% of the American diet consisting of ultra-processed options. These include soda, fast food, packaged foods, frozen meals, sweets, cereals, and canned soup. These foods are loaded with sodium, sugar, inflammatory fats, preservatives, artificial flavors, and colours. As a result, they offer very little nutrition, despite being calorie-dense.
The high consumption of processed foods in the American diet is partly due to convenience and cost. In today's fast-paced world, many Americans prioritize convenience over health, and processed foods are often more affordable than fresh, nutritious options. Additionally, the constant influx of messaging around overeating has led to a focus on calorie reduction, which can be easier to achieve through processed foods.
The overconsumption of processed foods has severe health consequences. It is a leading cause of death in America, contributing to weight gain, obesity, and an increased risk of chronic illnesses such as heart disease, stroke, diabetes, cancer, and fatty liver disease. Poor diet and sedentary lifestyles have led to high obesity rates, with almost 35% of adults in the US being obese, and this number is expected to increase to nearly 50% within 15 years.
The high intake of processed foods also disrupts the gut microbiome, allowing unhealthy bacteria to outnumber the beneficial ones. This can have far-reaching consequences, as gut health is linked to mental health and overall wellness.
To improve their diets, Americans are encouraged to increase their consumption of fruits, vegetables, whole grains, and lean meats, while reducing their intake of processed foods. Making these changes can have a significant impact on reducing the risk of chronic diseases and improving overall health.

Poor diet and sedentary lifestyle
The SAD typically includes an abundance of processed foods, fast food, and sugary items. These food choices are often driven by convenience and cost, with packaged foods being more affordable and accessible than fresh, nutritious options like fruits and vegetables. According to a 2010 report, three out of four Americans don't eat a single piece of fruit daily, and nine out of ten don't meet the minimum recommended vegetable intake. This lack of fruits and vegetables means that Americans are missing out on essential vitamins, minerals, antioxidants, and anti-inflammatory compounds.
The high consumption of added sugars in the American diet is particularly concerning. Sugar provides quick energy but lacks nutritional value and can disrupt the gut microbiome, increasing the risk of diabetes by throwing off blood sugar regulation. Alarmingly, the average American consumes around 19 teaspoons of sugar daily, adding up to 60 pounds of sugar per year. This excessive sugar intake is comparable to the consumption of street drugs like cocaine, indicating how addictive sugar can be.
Sedentary lifestyles compound the issue of poor diet, further increasing the risk of chronic illnesses. Adopting a sedentary lifestyle means spending most of the day sitting or lying down, with little to no physical activity. In today's fast-paced world, many Americans prioritise convenience over health, and this lifestyle choice, coupled with poor dietary choices, has contributed to the nation's health crisis.
To address these issues, Americans are encouraged to make healthier food choices, increase their physical activity, and limit their consumption of processed foods, added sugars, and solid fats (a combination of saturated and trans fats). By prioritising nutritious whole foods, increasing fruit and vegetable intake, and incorporating daily exercise, individuals can significantly reduce their risk of developing chronic diseases and improve their overall health and well-being.

Underconsumption of whole grains and low-fat dairy
The American diet is often associated with excess calories, saturated fats, trans fats, added sugars, and sodium. Poor diets and sedentary lifestyles have led to high rates of obesity, overweight, and diet-related chronic diseases, including cardiovascular disease, hypertension, and dyslipidemia.
A study found that 99% of Americans do not meet the minimum recommended daily intake of whole grains, which is about three to four ounces per day. Whole grains include whole-wheat flour, bulgur (cracked wheat), oatmeal, and brown rice. They are sources of magnesium and selenium, which are essential for bone health and energy release from muscles. Additionally, whole grains are a good source of dietary fiber, which is often lacking in refined grains.
The Dairy Group, one of the five food groups, includes milk, yogurt, cheese, lactose-free milk, and fortified soy milk and yogurt. Dairy products are a significant source of calcium, potassium, and vitamin D in many American diets. However, about 90% of Americans do not consume enough dairy, and most people would benefit from including more low-fat or fat-free dairy options in their diets.
Low-fat or fat-free dairy products have been a dietary staple since the 1980s when fat was considered unhealthy. Today, nutrition experts agree that dietary fat is essential, but the type and source of fat are crucial. Dairy products, unlike other healthy fat sources like olive oil, oily fish, and nuts, primarily contain saturated fat. Saturated fat has been linked to an increased risk of heart disease. Therefore, while dairy can be part of a healthy diet, it should be consumed in moderation, with a combination of low-fat and full-fat options.
In conclusion, Americans generally underconsume whole grains and low-fat dairy, which are important sources of essential nutrients. Increasing the consumption of these food groups as part of a balanced diet can have significant health benefits and reduce the risk of chronic diseases.
