Introduction To The Apo E Gene
We all have the Apo E gene (pronounced by saying each letter, A - P - O - E). This gene plays a key role in our body's internal environment and is a determining factor in the development of chronic disease, especially heart disease and Alzheimer’s disease.
The Apo E gene occurs as three variations, or alleles, in humans: Apo E 2, Apo E 3, and Apo E 4.
Since genes come in matching pairs, we each have two alleles of every gene, one from each parent. If you received an Apo E 2 from one parent and an Apo E 3 from the other parent, your genotype would be E 2/3. The six possible combinations of Apo E gene pairs are E 2/2, E 2/3, E 3/3, E 4/2, E 4/3, and E 4/4.
How Your Apo E Genotype Affects Your Health
As you can see from the table below, the most common genotype, Apo E 3/3, is found in approximately 64 percent of the population. It is considered the “neutral” Apo E genotype. Combinations that include either the Apo E 2 or Apo E 4 are considered “alternative” expressions of the more common Apo E 3 pairing. People with Apo E 2 or 4 alleles will process foods differently from the way in which an Apo E 3’s body will.

The specific pair of Apo E genes you inherited from your parents greatly influences your predisposition to certain illnesses, including heart disease, vascular dementia, Alzheimer's disease, Parkinson's disease, and cancer. For example, persons with the Apo E 4/4 genotype could have up to a 90 percent chance of developing a chronic illness such as Alzheimer's disease. Maintaining an optimal diet and lifestyle for your particular Apo E genotype is known as maintaining a "gene-supportive environment" (GSE), and doing so can dramatically reduce your risk of developing these chronic illnesses. That's why the Apo E Gene Diet was created.
The Apo E Gene Diet
The foundation of the Apo E Gene Diet is a nutritional plan that focuses on eating the optimal percentages of "The Big Three" - carbohydrates, fats and proteins - for your specific Apo E genotype. One diet does not fit all because each Apo E genotype processes foods differently. There is a unique optimal combination of carbohydrates, fats, and proteins which creates the ideal diet for each of the six Apo E genotypes. Creating this optimal balance in your diet provides the foundation for your good health.
The Apo E gene has been shown to be the number one factor affecting how your body uses The Big Three macronutrients or food groups, and this influences the possibility and severity of developing certain diseases. It is extremely important to eat the right balance of carbohydrates, fats and proteins for your specific Apo E genotype.
The Apo E Gene Diet is not a diet in the typical sense of the word. With the Apo E Gene Diet, we use the word "diet" to mean a series of specific recommendations for individual nutrition and other environmental factors, such as exercise and stress levels, to name a few. The goal of the Apo E Gene Diet is disease prevention and a healthy life; it is a personalized plan for your Apo E genotype which will guide you in choosing the optimal:
• fat content with the correct types of fats
• carbohydrate content with the correct types of carbohydrates
• protein content with the correct types of proteins
• caloric content for your needs
• amount and kind of exercise appropriate for you
• balance of stress and relaxation in your life
• quality of mental and emotional environment
• type of energy and intentions you allow into your life (the spiritual component)
Most of the existing dietary recommendations are based on the assumption that one diet plan is appropriate for everyone. Because of that assumption, those diets fail to accomplish long-term weight loss or optimal disease prevention. We are not all the same. In reality, diet and exercise recommendations must be individualized, beginning with a person's genetic foundational recipe.
The Apo E Gene Diet focuses on an individual’s genetic recipe, creating dietary and exercise recommendations for each of the six possible Apo E genotypes a person can have. No other program does this. In addition, the Apo E Gene Diet takes into account the whole person (physical, emotional, and spiritual) in creating a gene-supportive environment which promotes a healthy life, free of chronic illnesses.
The Optimal Diet and Lifestyle For Your Apo E Genotype
So how do you create the optimal diet and lifestyle for your particular Apo E genotype? There are three steps.
1. First, read The APO E Gene Diet by Pamela McDonald.
2. After reading the book, you can make an informed decision as to whether you want to know your Apo E genotype. Finding out which Apo E genotype you have is done through a simple cheek swab test or non-fasting blood test (more information on testing options).
3. Once you know your Apo E genotype, follow the diet and lifestyle plan outlined in the book for your particular Apo E genotype.
Following these three steps will support you on the path to a healthy life, free of chronic disease.
