You are what you eat? How healthy eating can improve your health.

Updated: Sep 11, 2023

The age-old saying, "You are what you eat," has resonated with us for generations. It emphasizes the profound link between our dietary choices and our overall health and well-being. However, it's not just a cliché; this phrase is true and functional medicine backs this thought up. Functional medicine is a holistic approach to healthcare that seeks to address the root causes of illness. In this blog post, we will dive deeper into the concept of "you are what you eat" and explore how it profoundly affects our health, particularly through the lens of functional medicine.

Understanding "You Are What You Eat"

The phrase "you are what you eat" underscores the idea that the foods we consume play a pivotal role in shaping our physical, mental, and emotional health. Every morsel of food or sip of a drink we put into our bodies contains essential nutrients, vitamins, minerals, and compounds that interact with our cells, tissues, and organs. This interaction influences our body's ability to function optimally.

  1. Nutrient Density: Consuming nutrient-dense foods provides the body with the essential building blocks it needs for growth, repair, and maintenance. This means we should keep your diet whole-food based, which eliminates foods that are highly processed and filled with added sugars. If you see a paragraph of ingredients on a food label that you cannot pronounce it probably is not natural!

  2. Inflammation: Certain foods, like highly processed and sugary items, can trigger inflammation in the body. Chronic inflammation is associated with various diseases, including heart disease, diabetes, and autoimmune conditions.

  3. Influence on Disease: What we eat can either bolster our defenses against disease or leave us vulnerable to various health issues. Nutrient-rich foods can enhance our immune system and overall resilience, while poor dietary choices can pave the way for chronic illnesses like heart disease, diabetes, and obesity. The immune suppressing effects of sugar can start in less than 30 minutes of consuming that food or drink and can last up to 5 hours after eating. Constant consumption of foods like these can cause a permanent dampening on the function of the immune system.

  4. Gut Health: A balanced diet is crucial for maintaining a healthy gut microbiome. The gut houses trillions of microorganisms that impact digestion, immunity, and even mental health. When your gut microbiome is imbalanced, we are more prone to developing gut infections and gut permeability, which leads to a wide array of health problems.

The Connection to Functional Medicine

Functional medicine is a patient-centered approach to healthcare that focuses on identifying and addressing the underlying causes of illness, rather than merely treating symptoms. It seeks to optimize the body's functioning by promoting wellness and preventing disease. The connection between "you are what you eat" and functional medicine lies in their shared belief in the power of nutrition to influence health and healing.

  1. Personalized Nutrition Plans: Functional medicine practitioners recognize that each person is unique. They create personalized nutrition plans tailored to individual needs, taking into account genetics, lifestyle, and environmental factors.

  2. Healing Through Food: In functional medicine, food is often viewed as medicine. Patients are encouraged to make dietary changes that can help resolve underlying health issues. For example, a diet rich in anti-inflammatory foods may be recommended to address chronic pain or autoimmune disorders.

  3. Gut-Brain Connection: Functional medicine acknowledges the intricate relationship between the gut and the brain. A healthy gut microbiome is believed to positively impact mental health, and dietary changes can play a vital role in restoring balance.

  4. Prevention and Wellness: Rather than waiting for disease to manifest, functional medicine emphasizes preventive care. Nutrition is a key component of this strategy, with a focus on maintaining optimal health through a well-balanced diet.


The phrase "you are what you eat" serves as a powerful reminder of the huge influence our dietary choices have on our health. Functional medicine takes this concept to the next level by integrating it into a comprehensive approach to healthcare. By recognizing the vital role of healthy eating and tailoring treatment plans accordingly, functional medicine empowers individuals to take control of their health and work towards a state of wellness. What we eat matters not just for our bodies, but for our overall quality of life. So, remember, the next time you sit down to a meal, you're not just filling your stomach; you're nourishing your entire being!
