Personalized Nutrition, Rooted in Science & Care

Our
Philosophy
Integrative and Functional Nutrition (IFN) is a forward-thinking approach to healthcare that focuses on identifying and addressing the root causes of disease rather than merely treating symptoms. It emphasizes a personalized, systems-oriented model that empowers patients to take an active role in their health (1).
This approach integrates traditional food wisdom, current evidence-based science, and the principles of Functional Medicine to provide a comprehensive strategy for health promotion, disease prevention, and nutritional treatment of chronic diseases (2).
"The power of food as medicine is more than just an idea. It's a practical solution that can help us heal our bodies, prevent disease, and achieve optimal health."

Core Principles of Integrative & Functional Nutrition
Integrative and Functional Nutrition revolves around a set of foundational principles that reshape the way we think about health and wellness. The approach is highly personalized, employs a systems biology approach, seeks to identify and address the root causes of health issues, and values the therapeutic relationship between the practitioner and the patient.
Individualized Care

Integrative and Functional Nutrition takes pride in its distinct approach to health and wellness - one that is far removed from the conventional "one-size-fits-all" model. IFN professionals understand that each person is unique, with their own specific nutritional needs. This individuality comes from a combination of our genetics, lifestyle choices, and the environment in which we live (1)
​
Genetics: Our genes play a substantial role in our health and well-being. They can influence our risk for certain health conditions, how we metabolize different nutrients, and even our preferences for certain foods. IFN acknowledges these genetic differences, using them as a guide to provide personalized dietary advice (2).
Lifestyle: Our daily habits - such as what we eat, how much we move, our sleep patterns, and how we manage stress - significantly influence our health. IFN professionals work closely with individuals to understand their lifestyle patterns and provide practical strategies for improvement that align with their personal needs and circumstances (3).
​
​Environment: Our surroundings, including where we live and work, the air we breathe, the water we drink, and our exposure to various toxins, can profoundly impact our health. IFN practitioners consider these environmental factors when developing personalized nutrition strategies, recognizing the need to support the body in the face of these challenges (4).

Dietary Guidelines
The approach of Integrative and Functional Nutrition (IFN) is rooted in systems biology, a field of study that understands that our bodies function not as separate parts, but as a complex, interconnected system. This comprehensive viewpoint is crucial because it recognizes that an issue in one area can influence health in another area, highlighting the interconnected nature of our bodies and health (1).
​
Here are few examples:
​
Digestion: The process of breaking down food and absorbing nutrients is essential for our overall health. But what if our gut health is compromised? This could not only lead to digestive issues like bloating, constipation, or discomfort but can also impact other areas of our health.
Mental health: A significant portion of our body's serotonin, a neurotransmitter that contributes to feelings of happiness and well-being, is produced in the gut. Therefore, issues with gut health can potentially impact our mood and contribute to conditions like depression and anxiety (2).
Immunity: Our immune system is intricately linked with our digestive system. In fact, approximately 70% of our immune cells are located in our gut. This means that any disruption in the gut can directly influence our immunity, making us more susceptible to infections and diseases (3).

The beauty of IFN's systems biology approach is its capacity to connect the dots between different body systems, providing a holistic view of an individual's health. It is through this understanding that IFN practitioners can create comprehensive and effective strategies to enhance health and well-being.

Root Cause Resolution

One of the defining principles of Integrative and Functional Nutrition (IFN) is its focus on root cause resolution. Unlike conventional models that often target symptoms alone, IFN seeks to uncover and address the underlying reasons for health problems. This strategy aims for long-lasting health improvements, rather than temporary relief of symptoms (1).​
​
Consider headaches, for example. In a conventional approach, the immediate response might be to recommend over-the-counter pain relievers. While these can be effective at relieving pain in the short term, they don't address the underlying cause of the headaches.
​​
IFN, on the other hand, asks, "Why are the headaches happening?" Could it be due to dehydration? A certain food intolerance? Stress? Hormonal imbalances? By diving deeper, an IFN practitioner can help you identify the root cause of the issue and provide strategies to address it.
This root cause resolution approach treats symptoms as clues to deeper imbalances within the body. They are signals that something is off balance and needs attention. Symptoms, from this viewpoint, are not problems to be suppressed but rather messages to be understood (2).
​
By identifying and addressing the root causes of health issues, IFN aims to restore balance in the body and promote sustainable health improvements. This is an empowering approach, allowing individuals to take control of their health, understanding their bodies better, and making informed decisions about their health and well-being.
"Rather than slapping on a diagnosis and giving an 'off-the-shelf' drug, we need to dig deeper and look at the whole person, the lifestyle, the stress — the root cause."

Therapeutic Relationship
The Integrative and Functional Nutrition (IFN) model places immense value on the relationship between the practitioner and the patient. This relationship is not just about prescribing a diet or treatment plan; it is about building an alliance that fosters empowerment, education, and self-care (1).
​
Empowerment: The goal of an IFN practitioner is not just to provide care, but also to empower individuals to take charge of their own health. This means equipping patients with the knowledge, skills, and confidence to make healthy decisions and changes in their lifestyle. Practitioners do this by providing personalized guidance, supporting individuals in their journey, and celebrating their victories along the way (2).
​
​Education: Knowledge is power when it comes to health. That's why education is a crucial part of the IFN approach. Practitioners strive to ensure that individuals understand their health conditions, the factors that contribute to them, and the steps they can take to improve their health. This might include education on nutrition, lifestyle habits, and how different factors interact to affect health (3).​

Self-care: The IFN approach understands that caring for oneself is an integral part of health and wellness. This might include developing healthy eating habits, practicing regular physical activity, ensuring restful sleep, managing stress, and nurturing emotional health. IFN practitioners provide strategies and support for self-care, understanding that it plays a critical role in maintaining health and preventing disease (4).

Application of Integrative & Functional Nutrition
Integrative and Functional Nutrition revolves around a set of foundational principles that reshape the way we think about health and wellness. The approach is highly personalized, employs a systems biology approach, seeks to identify and address the root causes of health issues, and values the therapeutic relationship between the practitioner and the patient.
Dietary Guidelines

IFN's dietary principles are not about quick-fix diets or restrictive eating. Instead, they emphasize a wholesome and sustainable approach to nutrition.
​
Whole Foods
A central tenet of IFN is the importance of whole foods, minimally processed and rich in nutrients. These include fruits, vegetables, lean proteins, whole grains, and healthy fats. Such foods provide the array of nutrients our bodies need to function optimally.
"Whole foods offer not just essential nutrients but a comprehensive array of health boosters, like fiber, phytonutrients, and a balanced combination of fats, protein, and carbs. These foods form the cornerstone of a vibrant, health-supporting diet." -
- Dr. Deanna Minich
Nutrient Density
Nutrient density means choosing foods that provide a high amount of nutrients relative to their calorie content. For example, a cup of spinach is more nutrient-dense than a cup of chips, as it provides a wider array of vitamins, minerals, and other health-promoting compounds for a similar number of calories.
​
Gut Health
Maintaining a healthy gut microbiome is also crucial. Our gut microbiota plays a pivotal role in many aspects of health, from digestion and nutrient absorption to immune function and even mood regulation. Foods that promote a healthy gut microbiome include those rich in fiber, like whole grains, fruits, and vegetables, as well as fermented foods like yogurt and sauerkraut.
Lifestyle Modifications
IFN recognizes that diet is just one piece of the health puzzle. Other lifestyle factors play a critical role in our well-being and are integral to the IFN approach.
​
Sleep
Sleep is essential for health. Poor sleep can contribute to a range of health problems, from weight gain and poor mental health to an increased risk of chronic diseases. IFN practitioners provide strategies to improve sleep quality and address any underlying issues that may be affecting sleep.
​
Stress Management
Stress management is another critical aspect. Chronic stress can negatively impact almost every system in the body and contribute to a variety of health problems. IFN emphasizes strategies to manage stress, such as mindfulness, yoga, and other relaxation techniques.

Physical Activity
Physical activity is also crucial. Regular exercise can help control weight, reduce the risk of chronic diseases, improve mental health, and boost overall well-being. IFN practitioners help individuals find forms of exercise that they enjoy and can maintain long-term.
Socialization
Social connections also play a role in health. Having strong, supportive relationships can help manage stress, improve mental health, and contribute to a longer, healthier life. IFN practitioners recognize the importance of this aspect and may provide strategies to foster social connections.
