High blood pressure is a dangerous condition that often leads to serious and sometimes fatal consequences. If you have been diagnosed with pre-high blood pressure it’s critical that you act immediately before the condition worsens into full-blown high blood pressure. If you already have high blood pressure, you should know that high blood pressure management is possible. Here are some tips for maintaining healthy blood pressure. 1. Quit Smoking There are lots of reasons to quit smoking, but did you know smoking increases the risk of high blood pressure? The very best thing you can do for your health is
Over the decades, authorities have published public dietary and nutritional guidelines in an attempt to inform individuals about the healthiest choices to optimize health and prevent disease. However, conflicting and sometimes contradictory messaging has often led to more confusion than clarity. With so many different types of diets and supplements available it is difficult to know if they are really right for you. We have all heard some people say that certain diets work wonders for them but unfortunately not all see the same success.
Part of the reason there are wide variations in individual responses to different diets and nutrition is due to genetic variation. People are unique at every single level of their being, from their hair color to their cells, which are influenced by our environment, dietary traditions and genetic individuality. Advances in understanding the complexities of human metabolism, including the nutrient pathways, enzymes and genes that those pathways depend on, uncover how certain versions of genes (SNPs) may act as metabolic “roadblocks”. As we will see, these genetic changes account for variations in an individual’s predisposition to disease and response to dietary interventions. In addition, SNPs can help predict the most appropriate dose and form of certain nutrients.
No More ‘One Size Fits All’: Personalized Treatment Strategies Backed by Research
We know from family and twin studies that there is a high degree of inheritance of certain chronic diseases, including obesity, metabolic syndrome and heart disease. The studies demonstrate a strong genetic influence in the risk of developing disease. Furthermore, significant advances in understanding the environment and gene interactions on the development of disease have led to our ability to predict the impact of nutrition on individual health. This understanding allows us to eliminate the ‘one size fits all approach’ when it comes to diet and nutrition.
Response to diet – Environment-gene interactions
There is a significant genetic predisposition to obesity, influencing caloric consumption, satiety levels, food choices and behavior around food. The good news is that these risk factors can be significantly modulated through diet-gene interactions.
For Some, Protein is Key
The FTO gene, coined the fat-mass and obesity gene, significantly influences risk for weight gain, affecting satiety levels and total caloric intake. Those with a particular version of the gene have a 1.8-fold increased risk of obesity, higher BMI and waist circumference unless protein intake is above 18% of total energy intake. This variation also influences the ability to lose weight in response to diet and physical activity. Studies show that those with the AA genotype lost considerably more fat mass on a high protein diet, compared to individuals with the TT or TA genotypes who showed no difference in weight loss on a low protein versus a high protein diet. (Corella et al., 2012) (Merritt et al., 2018)
The Skinny on Total Fat and Saturated Fat
Significant advances in understanding the relationship between fat consumption and obesity have been revealed through genetics. In those with certain versions of the APOA2 gene, an increase in calorie consumption and weight gain exist. However, this effect is only present when those individuals have a diet high in saturated fat (more than 22g of fat). (Corella, 2009; Domínguez-Reyes et al., 2015).
In a study involving 1020 men and 1110 women, those with a certain version of the LIPC gene who consumed a diet with less than 30% of energy from fat had significantly higher HDL-C (good cholesterol) concentrations. If total fat consumption was above 30%, the effects were deleterious. This study shows clearly how the environment (in the form of diet) can impact genes. (Ordovas et al., 2002)
Improving Guidelines for Nutrients
Variations in the genetic code significantly influence risk for nutrient deficiency. Changes in your genes can impair nutrient absorption, transportation, cellular uptake, and intracellular conversion into active forms. (Paul and Brady, 2017) For example, genetic variations that affect folate metabolism and the subsequent production of homocysteine, an independent risk factor for heart disease, contribute to significant differences in folate and B12 requirements between individuals.
Research consistently shows that individuals with a certain version of the MTHFR gene have a reduction in folate levels in their blood and an elevation in homocysteine, even with the same dietary intake of folate as those with the normative version of the MTHFR gene. (Willems et al., 2004)
By understanding individual genetic variations, scientists can determine the specific form and dose of nutrients and supplements that are most effective for certain people. This has led to the development of improved vitamins and nutraceuticals. For example, the active form of folate, 5-MTHFR, which is seven times more bioavailable than its synthetic counterpart, folic acid, is now available. In the United States, the recommended daily allowance (RDA) of Vitamin B12 is set at 2.4 mcg per day. However, up to 30% of adults have issues absorbing B12, due to aging, digestive disease or genetics; their absorption rates may plummet to as low as 1%. Clinical studies show that high doses of B12, ranging from 1 to 3 mg in the form of methylcobalamin, are effective at overcoming absorption issues and inborn genetic variations of B12 metabolism. (Paul and Brady, 2017)
These examples show how understanding individual genetic variations can significantly impact the response to dietary interventions, nutrient dose and form and overall disease prevention. In 2015, the World Health Organization (WHO) modified its guidelines for optimal folate level as a result of this research. (Zhang et al., 2013)(National Academies of Sciences, Engineering, and Medicine et al., 2018)

(Kaufman et al., 2012)
A unique pledge of customer privacy – Finally, there are growing concerns about privacy relating to the use of one’s personal genetic information. Specific legislation has been passed within North America prohibiting employers and insurance companies from discriminating against individuals based on the results of a genetic test. These include the Genetic Information Non-Discrimination Act (GINA) in the US and the Genetic Non-Discrimination Act (GNA) in Canada; however, these laws are not all-encompassing. Other direct-to-consumer (DTC) genetic companies sell de-identified genetic data collected from their testing to third-party companies for both research and product development purposes, including big pharma. While AOR is a strong supporter of research, we pledge to NEVER SELL anyone’s genetic data to a third party.
