Diet has a profound impact on the human body, and this extends to the face. The food we eat can affect the development of our skull and facial bones, the shape of our teeth and jaw, and the health and appearance of our skin. For example, a diet rich in sugar, gluten, dairy, and alcohol can cause acne, inflammation, and dehydration. In addition, the introduction of softer, more calorie-dense foods has led to smaller jaws and changes in facial structure, with implications for oral functions such as chewing and breathing.

What You'll Learn
Diet and skin health
Sugar, for instance, can lead to premature ageing and a "sugar face", while gluten can result in what is described as a "gluten face", which may be related to an intolerance or overconsumption of carbohydrates. Dairy may also cause a "dairy face", possibly due to lactose intolerance, and it can trigger acne due to increased testosterone and other androgen production, influencing the skin's hormone receptors. Alcohol can also lead to inflammation and dehydration, damaging the immune system and contributing to ageing.
In addition to specific foods, the overall diet and lifestyle can influence skin health. Our ancestors, as hunter-gatherers, consumed tougher and chewier foods that stimulated their jaws, contributing to proper bone and jaw growth and health. In contrast, today's diet often includes softer, more processed foods that may lack the necessary nutrients, vitamins, and minerals for optimal bone development. This shift in diet has led to changes in facial structure, with human faces becoming smaller over the last few thousand years.
To maintain healthy skin, it is essential to stay hydrated by drinking plenty of water, as it provides the body's organs with moisture, helping to prevent dry and inflamed pores and reducing the likelihood of breakouts. While medical-grade skincare products can enhance skin appearance, addressing internal factors, such as diet, plays a significant role in achieving clear, glowing, and healthy skin.

Diet and jaw development
Diet has a significant impact on jaw development, with research suggesting that a soft modern diet may cause the lower jaw to grow too short and small relative to the size of the teeth. This can lead to orthodontic problems such as malocclusion and impacted wisdom teeth. The agricultural revolution marked a shift towards softer, more calorie-dense foods, and this trend has continued with the introduction of heavily processed foods and kitchen equipment that further reduces the need for chewing.
Our ancestors, who were hunter-gatherers, consumed a significant amount of tough, chewy foods that provided ample stimulation for their jaws. In contrast, today's diet often consists of softer, well-cooked foods that require minimal chewing. This reduction in masticatory function has been linked to changes in the mandible, including decreased bone mass. Clinical studies have reported a positive relationship between masticatory performance and tongue pressure in adults, highlighting the importance of adequate chewing and tongue function for optimal jaw development.
Research has also found a link between diet and jaw bone metabolism. A soft diet has been shown to negatively impact bone formation and mineralization in the maxilla and mandible, while a hard diet can promote bone growth and recovery. For example, studies in rats have demonstrated that a powdered diet can suppress bone growth in various directions, including the posterior, superior, and buccal directions. This suggests that adequate chewing is necessary to stimulate jaw bone development and maintain proper oral function.
Additionally, certain diets, such as the Paleo diet, have been proposed to positively affect jaw development and brain size. A diet rich in omega-3 fatty acids and leafy greens is recommended to support healthy jaw development and potentially enhance intelligence. Overall, it is clear that diet plays a crucial role in jaw development, and a balanced, nutrient-rich diet is essential for optimal oral health and facial development.

Diet and facial symmetry
Diet plays a significant role in determining facial symmetry. Leading experts in ancestral nutrition, Dr. Shanahan and Dr. Weston Price, have explored the link between nutrient deficiencies and facial symmetry. In his book, "Nutrition and Physical Degeneration", Dr. Price describes how our ancestors achieved full faces, straight teeth, and enhanced physical symmetry through their diet. This included grass-fed meats, organ meats, eggs from pastured chickens, raw milk and butter, cod liver oil, fish eggs, fermented foods, soaked nuts, properly prepared grains, and fresh fruits and vegetables. These foods are rich sources of fat-soluble vitamins A, D, E, and K, which are essential for bone development.
Dr. Price also found that children who are deprived of these nutrients during critical periods of growth tend to develop weak bone structures and facial asymmetries. Similarly, Dr. Lin, in his book "The Dental Diet", emphasizes the impact of diet and key nutrients on facial symmetry and bone structure. He highlights the importance of fat-soluble vitamins A, D, E, and K2, as well as calcium, for maintaining healthy teeth, gums, and bone structure.
Modern diets, characterized by softer and more processed foods, have contributed to changes in facial structure over time. Our ancestors, as hunter-gatherers, consumed tougher and chewier foods that provided more stimulation to their jaws. In contrast, today's diets often consist of softer, well-cooked foods that require less chewing. This reduction in chewing activity can influence the development of the jawbone and facial bones, leading to narrower dental arches, malocclusion, and impacted wisdom teeth.
Additionally, certain dietary habits can impact skin health, which indirectly affects facial appearance. For example, dairy products can trigger acne due to their influence on hormone receptors in the skin. Alcohol consumption can also cause inflammation and dehydration, damaging the skin over time. On the other hand, staying hydrated by drinking plenty of water can promote clear and glowing skin, reducing breakouts and improving overall skin health.

Diet and facial bone structure
Diet plays a crucial role in the development and structure of our facial bones. While genetics is a factor, it is not the sole determinant of our facial features. The interaction between genetics and the environment, including our diet, influences how our facial bones grow and develop.
The shift from a primitive hunter-gatherer diet to modern industrialized agriculture has significantly altered our facial appearance. Our ancestors consumed tougher, chewier foods that provided ample stimulation for their jaws. In contrast, today's diet often consists of softer, less challenging foods, leading to changes in our dentition and facial bone development.
A soft, refined, and processed diet can impact the formation of our palates and the growth of our jaws. Studies suggest that orthodontic issues, such as crowded teeth and impacted molars or wisdom teeth, are more prevalent in people from urban areas due to their softer, modern diet. This type of diet contributes to a shorter and smaller jaw compared to the size of their teeth, leading to teeth crowding issues.
Additionally, certain dietary habits can influence skin health, which also contributes to our overall facial appearance. For example, a diet high in dairy products may trigger acne breakouts due to the stimulation of hormones similar to insulin, such as IGF-1. On the other hand, drinking plenty of water can promote clear and healthy skin by providing the body's organs with the moisture they need, resulting in a radiant "glow-from-within" complexion.
To promote healthy facial bone structure and overall facial appearance, it is essential to consume a balanced and nutrient-rich diet. This includes incorporating raw fruits and vegetables, calcium-rich foods like almonds and kale, and adequate dietary fat and fat-soluble vitamins like vitamins A, D, E, and K2. By doing so, we can positively influence the development and appearance of our facial bones, teeth, and skin.

Diet and teeth
Diet plays a significant role in maintaining dental health. A nutrient-rich diet is essential for the development of the jawbone and facial bones, impacting the overall facial profile. The modern diet, often comprising softer, calorie-dense foods, has led to changes in facial structure, resulting in narrower dental arches and impacted wisdom teeth.
To maintain healthy teeth, it is crucial to limit sugary foods and drinks, as they contribute to tooth decay and enamel breakdown. Sugary substances promote the production of plaque, which produces acids that destroy tooth enamel, leading to cavities. It is recommended to consume sugary treats during mealtimes to reduce the risk of tooth decay. Additionally, acidic foods should be consumed in moderation, as they can increase the acidity of the mouth and contribute to mineral loss in the teeth.
A well-balanced diet, as recommended by the USDA, includes whole grains, such as brown rice, oatmeal, and whole wheat bread, as well as a variety of fruits, vegetables, and protein sources like fish, beans, nuts, and seeds. These foods provide essential vitamins, minerals, and nutrients that support gum and tooth health. For instance, vitamin D helps the body absorb calcium, which is vital for maintaining strong teeth and bones.
It is worth noting that certain diets, such as low-fat or low-carb diets, can have unintended consequences for oral health. Low-fat diets can interfere with the absorption of fat-soluble vitamins, including vitamin D, leading to potential tooth and bone breakdown. Similarly, low-carb diets can result in "keto-breath," caused by high levels of ketones in the body, which can induce ketoacidosis and lead to other health issues.
In conclusion, a healthy diet that provides the necessary nutrients, vitamins, and minerals is essential for maintaining strong teeth and supporting overall oral health. Limiting sugary and acidic foods, following a balanced diet, and practicing proper dental hygiene, including regular professional cleanings, are key factors in preserving dental health and preventing tooth decay and other oral issues.
