Eat a Whole Foods Diet for Longevity and Improved Quality of Life

Your body is composed of over 30 trillion cells, each of which is continually listening and responding to environmental signals. Your cells have antennas embedded in their cellular membranes. This is how your cells listen, relay messages to your DNA, and respond to your environment by activating biochemical processes. The food you eat carries information, which the antennas sense and then tell your cells how to behave. You either turn on your anti-aging, disease-prevention, and anti-inflammatory pathways or you turn on your inflammatory, aging, and disease pathways with every bite of food.

For each individual, the foods that prevent disease or turn it on may be different, however, a foundational place for anyone to begin is to remove all processed foods from one's diet and consume a whole foods diet. Removing processed foods and consuming a whole foods diet is one of the most powerful core principles of health and longevity that everyone can benefit from.

Research indicates that over 80% of chronic disease is preventable through dietary changes, moderate exercise, maintenance of a healthy weight, and tobacco cessation. This may seem so simple, however, currently in the United States, more than 50% of all calories consumed are coming from ultra-processed foods!

Improve the quality of your food to improve the quality of your life. 

Highly processed foods generally contain fat and sugar in high amounts, combined with flavor enhancers to make them incredibly addictive. This can trigger a surge of dopamine in the brain after consumption, making it very difficult to stop eating them. This is why the re-wiring process can take time; you are actually re-wiring this circuitry in your brain. Sleep, exercise, alcohol reduction, nutrient repletion, gut healing, and a whole foods diet will gradually balance dopamine to reduce and eliminate cravings for unhealthy foods or habits.

QUOTE LAO TZU

The best antidote to a processed foods diet is to simply cook your meals at home using whole food ingredients! Cooking nearly all of your meals from scratch at home takes time and practice. Create realistic meal plans starting with two to three whole-food-based meals, and build from there. Starting your day with a high-quality breakfast based on protein, fiber, and healthy fats is one of the best ways to begin to transform your health. A meal like this will reduce cravings and change the messages being sent to your cells for the rest of the day! 

It's the things you do daily that have the most impact on your health. The food you eat, the water you drink, the air you breathe, and the thoughts you think all send signals to your DNA to change how your body functions. Additionally, the types of microbes that live in your gut are messengers that tell your cells how to behave. The food you eat feeds these microbes, which either creates a calm, anti-inflammatory environment or turns on inflammatory pathways that can lead to disease. Since food is something you can control, then you can start to reprogram every cell in your body by changing your food. 

What is the best diet to start with?

If you are ready to transform your relationship with food and begin a healthy eating plan that can carry you through life, there are several foundational diet plans that can get you there. The easiest and most basic whole-food-based diets that include a wide variety of foods are the Clean Eating Diet and IFM Core Food Plan. Both of these diets will lay a strong foundation for health and teach you to cook with a wide variety of whole foods. Remember, diet diversity is a key component to health and longevity. 

Two other diets to begin with that include a wide-variety of whole foods are the Mediterranean Diet and the Paleo Diet. The Mediterranean Diet leans towards eating more plant-based meals, while the Paleo Diet is focused on more animal-based meals. You might find that a balance of the two suits you bestsome days more plant-based, and some days more animal-based. As you become more in-tune with your body and what it needs, the type of diet becomes less important. As long as you are consuming whole foods, learning to listen to what you need on a daily basis will be a key aspect to your health and wellness journey. 

Here's how to set up your kitchen for success:

  1. Go through your pantry, freezer, and refrigerator and remove all types of highly processed and packaged foods
  2. Remove all refined oils from your kitchen such as vegetable oil, canola oil, and peanut oil. Stock your kitchen with healthy fats and oils such as extra virgin olive oil, coconut oil, avocado oil, and organic butter or ghee.
  3. Go to your local health food store and buy several varieties of whole grains and dried beans, such as black rice, brown rice, quinoa, rolled oats, black beans, chickpeas, and lentils (store these in glass jars in your pantry). Canned, organic beans are great to have on hand as well! I always keep organic, canned black beans, chickpeas, and refried beans on hand for quick meals!
  4. Fill your freezer with organic or pasture-raised meat and poultry, as well as wild-caught fish.
  5. Go to the bulk bins at your local health food store and buy a few different varieties of raw nuts and seeds and store them in glass jars in your refrigerator or freezer. Raw almonds, walnuts, pecans, sunflower seeds, pumpkin seeds, flax seeds, and chia seeds are all excellent choices.
  6. Create a medicinal spice cabinet or drawer! Stock up on small jars of organic herbs and spices and keep them organized so they are easier to use. 
  7. Replace sugar and corn syrup with low-glycemic coconut sugar and pure maple syrup.
  8. Fill your freezer with frozen organic berries and other organic fruits for smoothies, snacking, and healthy baking recipes. 
  9. Stock up on fresh, organic fruits and vegetables regularly.
  10. Use healthy, minimally processed foods to keep you on track with healthy eating. Organic rice cakes, almond flour crackers, sprouted corn tortillas, organic preservative-free dried fruits, and dry-roasted macadamia nuts all make healthy, quick snacks! 
  11. Add healthy condiments to your refrigerator and pantry such as dijon mustard, coconut aminos, wheat-free tamari, raw apple cider vinegar, organic balsamic vinegar, brown rice vinegar, and white wine vinegar.

Letting Go of Food Addictions During an Elimination Diet

Food is more than just fuel—it’s emotional, cultural, and deeply tied to our daily habits. But for many, it also becomes a source of addiction, keeping us stuck in negative cycles of cravings, energy crashes, and emotional eating. Processed foods, high in sugar, unhealthy fats, and artificial additives, are designed to hijack our brain’s reward system, triggering dopamine releases that make us reach for more, even when we know they’re harming our health. Letting go of food addictions isn’t just about willpower—it’s about breaking free from old patterns and stepping into alignment with your future self. Over the years, one of the biggest struggles I’ve seen during the elimination diet process is the difficulty of letting go of foods that have been part of one’s daily diet for years—or even decades. The cravings for sugar, gluten, dairy, and processed foods can feel overwhelming, and ironically, they often get stronger when we try to break away from them.

How Food Sensitivities Trigger Autoimmunity: The Hidden Connection

Autoimmune diseases are on the rise, affecting millions of people worldwide and leaving many struggling with unexplained symptoms, chronic pain, and fatigue. While genetics play a role, emerging research highlights the profound influence of environmental factors—especially diet—on the development and progression of autoimmunity. The foods we eat can either calm inflammation and support immune balance or trigger immune overactivity, leading the body to mistakenly attack its own tissues. This means that every meal is either contributing to healing or fueling disease. The connection between food and autoimmunity is powerful, and for those suffering from conditions like Hashimoto’s, rheumatoid arthritis, lupus, or inflammatory bowel disease, dietary changes can be life-changing.

The Elimination Diet: A Path to Healing and Personalized Nutrition

Food has a profound impact on our health, influencing everything from digestion and inflammation to energy levels and mental clarity. But for many, certain foods can trigger unwanted symptoms without them even realizing it. An Elimination Diet is a structured approach to identifying food sensitivities and intolerances by removing common trigger foods for a period of time, then systematically reintroducing them to observe how the body reacts. Unlike food allergies, which cause an immediate immune reaction, food sensitivities often create delayed or chronic symptoms that can be difficult to pinpoint. These reactions may manifest as digestive distress, fatigue, joint pain, brain fog, migraines, skin conditions, sinus congestion, or autoimmune flare-ups.
