The typical American diet has changed over the decades, with Americans consuming 29% more grains, mostly in the form of bread, pastries, and other baked goods, than they did in 1970. The average American diet is often dubbed the Standard American Diet (SAD) and is characterized by a high consumption of processed foods, red meats, and sugary beverages. The average American consumed 2,481 calories a day in 2010, about 23% more than in 1970. The diet of an average American is woven from the threads of rapid lifestyle changes, economic shifts, and evolving food preferences. Caloric consumption is an oversimplification of nutritional needs, as calories are simply units of energy. However, knowing a rough estimate of daily caloric intake can be a launching point to understand whether one is getting enough energy.

What You'll Learn
Calories from grains, flours, and corn products
Grains, flours, and corn products are a significant source of calories in the typical American diet. According to the Economic Research Service, grains were the primary contributor to daily calories per capita in both 2000 and 2010, with 596 and 581 calories, respectively. This includes wheat flour, corn products, and other grains like rye flour, oat products, and barley products.
In 2014, Americans consumed an average of 6.7 ounce-equivalents of these grain products per day, which is a 35% increase from 1970. The consumption of corn products specifically grew by 202%, reflecting the popularity of corn-based foods like tortillas and chips, as well as the use of cornstarch in processed foods. This shift towards more corn product consumption is notable, as corn is a staple crop in the United States and has a significant presence in the American diet.
The 2015-2020 Dietary Guidelines for Americans recommend that individuals requiring 2,000 calories per day consume 6 ounce-equivalents of grains, with at least half being whole grains. Whole grains include whole-wheat flour, bulgur (cracked wheat), oatmeal, and brown rice. They are important sources of magnesium, selenium, and dietary fiber. Additionally, eating whole grains can reduce the risk of heart disease and support healthy digestion.
However, it's important to note that most Americans consume more refined grains than whole grains. Refined grains have been milled, which gives them a finer texture and improves their shelf life, but it also removes dietary fiber, iron, and B vitamins. Examples of refined grain products include white flour, corn grits, white bread, and white rice. To compensate for the loss of nutrients, refined grains should be enriched by adding back certain B vitamins and iron.
In summary, grains, flours, and corn products are a major contributor to the calorie intake of Americans, with corn products seeing a significant increase in consumption. While whole grains are recommended for their nutritional benefits, refined grains are more prevalent in the typical American diet.

Calories from fats and oils
In 2000 and 2010, added plant-based fats and oils, such as salad and cooking oils, margarine, and shortening, ranked second in terms of calorie contribution to the American diet. During these years, these fats and oils accounted for 480 and 518 calories, respectively, out of the total daily calories. This contribution from plant-based fats and oils is notable, considering that grains were the primary source of calories, with 596 calories in 2000 and 581 calories in 2010.
The American diet also includes a significant proportion of calories from animal-based fats and oils. Meat, poultry, and fish contributed 438 calories in 2000 and 416 calories in 2010. While the overall percentage of calories from these sources remained stable at 17% in both years, there were shifts within the category. Calories from poultry and fish increased, while those from red meat decreased.
It is important to distinguish between healthy and unhealthy fats when discussing calories from fats and oils. Unsaturated fats, such as canola, soybean, and olive oil, are considered healthier options. Replacing foods high in saturated and trans fats with unsaturated fats can help lower the risk of heart disease by improving cholesterol levels. The American Heart Association recommends limiting saturated fats to less than 6% of total calories. Saturated fats are found in animal-based foods like red meat, butter, cheese, and tropical oils like coconut and palm oil.
While this information provides insights into the calorie distribution of the typical American diet, it is worth noting that individual dietary needs and perceptions may vary. Some Americans may intentionally restrict their calorie intake to lose weight or for health reasons, while others may consume more calories than their bodies require. Additionally, the impact of dietary choices on health extends beyond calorie counts to the types of nutrients consumed and the overall lifestyle of an individual.

Calories from meat, poultry, and fish
The calorie content of meat, fish, and poultry varies depending on the type and cut. Red meat, for instance, tends to have a higher calorie count than poultry. Poultry, such as chicken and turkey, is generally lower in calories compared to other meat options. Fish also shows variation, with "oily" fish like salmon and tuna containing more calories than "white" fish like cod and haddock. Trimming visible fat and selecting leaner cuts can reduce the calorie intake from meat.
The contribution of meat, poultry, and fish to an individual's calorie intake can depend on various factors, including age and dietary preferences. Adults tend to derive a larger proportion of their calories from this food group compared to children aged 3 to 14, who get a slightly smaller percentage of their calories from meat, poultry, and fish. However, it is worth noting that the recommended daily protein intake varies between men and women, with men requiring 56g and women 45g (for those aged 19-50).
In terms of broader dietary patterns, the typical American diet has seen a shift in calorie intake over time. Between 2000 and 2010, the average daily calories per person decreased by 2%, from 2,545 to 2,481. This decrease may reflect changing dietary habits and increasing awareness of nutritional needs. However, it is important to note that caloric consumption is just one aspect of nutrition, and a balanced diet also considers the intake of essential nutrients and overall health and energy levels.
While the focus on calories can provide insight into dietary patterns, it does not always equate to nutritional health. For example, some individuals may consume a high number of calories but lack essential nutrients, leading to malnutrition. On the other hand, diets extremely low in calories can also be detrimental to health and are often associated with nutrient deficiencies and even eating disorders. Therefore, it is crucial to view calorie intake as just one component of a holistic approach to nutrition and well-being.

Calories from sugar and sweeteners
The average daily intake of added sugars in the US varies by age, sex, and race. In 2017-2018, children and young adults aged 2-19 years consumed 17 teaspoons of added sugars daily, with higher intake among boys (18 teaspoons) than girls (15 teaspoons). Similarly, adults aged 20 and older consumed 17 teaspoons daily, with men averaging 19 teaspoons and women 15 teaspoons. These values translate to a significant calorie intake from added sugars alone.
The American Heart Association recommends limiting added sugars to no more than 6% of daily calories. For a 2,000-calorie diet, this equates to 50 grams or 200 calories from added sugars. However, it's important to note that added sugars should be just one consideration when evaluating overall diet health.
Sugar-sweetened beverages, such as soda, are a significant contributor to added sugar intake in the American diet. While these drinks provide a pleasant flavor, they offer little to no nutritional value and are associated with negative health effects. Additionally, baked goods, desserts, and sweets are other common sources of added sugars in the American diet.
While there is a general awareness of the negative health impacts of excessive sugar consumption, many people may not realize the true extent of their sugar intake. Reading nutrition labels and understanding the various names for sugar can help individuals make more informed dietary choices and reduce their added sugar intake.

Caloric intake and health implications
Caloric intake is a complex issue, and it is important to note that individual needs vary. For instance, a 40-year-old man of average height and weight who is moderately active requires 2,400 calories, while a woman with the same characteristics needs 1,850 calories. However, the average American diet exceeds the necessary intake to maintain a healthy body mass index (BMI), contributing to weight gain and obesity.
The typical American diet has been estimated at about 2,200 to 2,481 calories per day, with 50% of calories from carbohydrates, 15% from protein, and 35% from fat. While these macronutrient intakes fall within the Acceptable Macronutrient Distribution Ranges (AMDR) for adults, the nutritional quality of specific foods is often poor. The diet is typically high in processed foods, red meats, sugary beverages, and low in fresh fruits, vegetables, and whole grains. This imbalance results in nutritional deficiencies, disrupted metabolic processes, and increased inflammation, setting the stage for chronic diseases and compromised physical and mental health.
The Western pattern diet, which includes the typical American diet, is positively correlated with an elevated risk of obesity, heart disease, cancer, metabolic syndrome, and other diseases. The excessive consumption of oils, saturated fats, and added sugars is prevalent, with 89% of Americans consuming more sodium than recommended. This diet also includes more chicken and less beef, less milk, and a significant decrease in sugar intake, replaced by corn-derived sweeteners.
While caloric intake is an oversimplification of nutritional needs, it can serve as a starting point to understand energy levels. A diet of less than 1,000 calories per day is associated with nutrient deficiencies and may indicate an eating disorder. However, it is important to note that not eating enough calories can also lead to health issues related to malnutrition. Therefore, a balanced approach to nutrition and caloric intake is crucial for maintaining overall health and well-being.
In conclusion, the health implications of the typical American diet are far-reaching due to its high caloric content and poor nutritional quality. To improve health outcomes, a shift towards whole, nutrient-dense foods is necessary, reducing the intake of highly processed, high-calorie foods.
