(the art of eating according to your genes)
Nutri- (i.e., Nutrition)-genomics (i.e, genetics) is the sciences that uses DNA components to inform us on the relationship between our genetics, diet, and risk of diseases. It also, encompasses the effect of diet on genetic changes.
It's been known for decades that “one size doesn’t fit all”, but were still missing many pieces of the puzzle when it comes to nutrition. Thanks to omics technology nowadays we are able to answer we people respond to diet and exercise differently, and nutrigenomics was one of the reason. Providing nutrition recommendation tailored to individual's genetic-make is one of the main approaches to providing a “Personalized Nutrition” plans. Recent nutrigenomics studies have shown that genetics influence the rate of weight loss, fat, protein and carbohydrate metabolism, as well as eating habits and body response to different type of exercises.
Nutrigenomics test allows you to examine your body response to:
1- Macro nutrients (fat, carbohydrate, etc)
2- Metabolism and weight loss
3- Eating habits
4- Micronutrients metabolism and risk of diseases (vitamin B complex, omega 3, vitamin D, and calcium)
5- Body response to sport and exercises
6- Bone & joint health, risk of injury
Your genes load the gun,
your choices pull the trigger
Healthy aging starts from the moment you are born. Similarly, environmental factors, such as diet, start to influence your genetics at the first stage in life.
Diet can modify your genetic effect and thus enhances or decreases risk of disease based on what you choose to eat.
Tiered of following many different diet, do you find yourself reaching a plateau and don't know what to do?
Are you an athlete who is competing or playing in a team.
The gene diet is planned based on your body unique genes, and it identify your strength and weaknesses when it comes to body response to different type of diets and exercises.
Some nutrients deficiencies are more prevalent in certain cultures compared to others. Simply due to the effect of genetics on nutrients absorption and metabolism.
Vitamins and Minerals are essential in many steps in cell cycling, DNA methylation, oxygen transportation, cell death and repair! Thus, are crucial to be suffeciennt during fertilization, pregnancy, and early stages of life.
Meet Our Diet
Ohood Alharbi MScFN, PhD is the founder of Personalize My Diet, an online nutrition clinic specialized in nutrigenomics and personalized diet. Dr. Ohood completed her undergraduate degree in Medical Laboratories specializing in microbiology and genetics. She was awarded her Masters degree in Food and Nutritional Sciences and her PhD in nutrigenomics (aka how to eat according to your genes) in 2018. During her PhD, she also completed Independent-Dietetic Practicum in different settings including Nurse Practitioner community clinic, Retirement community and long term care as well as home care. Dr. Ohood, however, is not practicing as a dietitian.
Dr. Ohood completed her PhD studying the association between dairy products and risk of cardiometabolic diseases using the genetics of lactose intolerance as an indicator of dairy consumption. Individuals with lactose intolerance lack the enzyme lactose that digest lactose the main sugar in milk. Her PhD research results showed that genotypes of lactose intolerance are predictive of dairy intake and vitamin D blood levels. Furthermore, the genotype predicting lactose intolerance was associated with changes in metabolites (known as proteomes) only when consuming dairy products. These results are novel and the mechanisms behind it are still unknown; however, speculation of the involvement of the gut microbiome is plausible. Therefore, Dr. Ohood is dedicating her time to understand the interaction between genetics, dairy, and the gut microbiome.
Dr. Ohood is also a public speaker, she presented in different organization to educate and spread awareness about the interaction between diet, genetics, and health. She has been a reviewer in multiple scientific journal including PEN: a Practice-based Evidence in Nutrition, a powerful database delivering evidence-based answers to health professionals.
