Too much of a good thing: Mushrooms intolerance and your genes

mushroom_intolerance

I love mushrooms and can eat them in abundance – especially sauteed in a little butter with some salt sprinkled on them!  Yum!  So I was fascinated to read a study that linked mushrooms, a certain gene variant, and Crohn’s disease symptoms. The study, Mushroom intolerance: a novel diet-gene interaction in Crohn’s disease, was published in …

Carbohydrate metabolism: Your genes play a role in insulin and blood glucose levels

Carbs

When it comes to advice about the best diet, the things that everyone seems to accept as gospel don’t always hold true when researchers actually look into them.  Take the glycemic index for example: Around since the 1980’s, accepted dogma holds that white bread will very quickly raise everyone’s blood glucose levels with a GI …

Interaction between high fat diet and ACE deletion

ACE-deletion

Wondering if you should cut down on red meat and fat to lower your blood pressure?  According to a new study, it could depend on your genes. A recent study in the Journal of the American Heart Association illustrates once again the interaction between genetics and diet.  The study looked at blood pressure measurements in …

Building Up Iron – Genetics, Diet, and Health Effects

I have blogged before about hemochromatosis and the importance of checking your DNA results for the genetic variants that cause it, but I’m revisiting the topic today with updated research on the topic of iron overload. This is a personal cause for me, and getting the word out to as many people as possible is …

Increased Inflammation and IL-17A Polymorphisms

Inflammation (1)

In looking into the effects of emulsifiers on our gut, I came across quite a few genetic polymorphisms that are involved in increased inflammation and increased risk of inflammatory bowel diseases.  IL-17A is one of these pro-inflammatory gene polymorphisms. IL-17A is a pro-inflammatory part of our immune system that, while necessary in times of injury …

Vitamin C Levels and Your Genes

vitamin-cgenes

As the weather here turns colder, thoughts turn to preventing colds and the flu.  My “go to” method of preventing sickness has always been by loading up on vitamin C, even though recent studies haven’t really supported the idea that vitamin C increase immune function. At my house, if you have the sniffles it is …

Medium chain acyl-CoA dehydrogenase deficiency

Medium Chain Acyl-CoA Dehydrogenase Deficiency

Medium-chain acyl-COA dehydrogenase (MCAD) deficiency is an “inborn error of metabolism” in which there is an impaired ability to break down medium-chain fatty acids.  In a nutshell, the body can use either glucose (through glycolysis) or fatty acids (through beta oxidation) to begin producing energy in the mitochondria.  MCAD deficiency affects the body’s ability to …

Riboflavin, MTHFR, and other Genetic Polymorphisms

Riboflavin (Vitamin B2) helps some people with certain genetic polymorphisms.

Riboflavin (Vitamin B2) is a water soluble vitamin that is a co-factor for many enzymes in the body.  To put it in simpler terms: riboflavin is vitally important! Riboflavin is a ribose sugar bound to a flavin molecule.  It is the precursor to FMN (flavin mononucleotide) and FAD (flavin adenine dinucleotide), which are coenzymes involved …

Genetics of Biotin Deficiency

biotin-deficiency

Biotin, also known as vitamin B7 or vitamin H, is a cofactor which aids in the metabolism of fats, carbohydrates, and proteins.  Biotin deficiency due to diet is pretty rare, but eating raw egg whites for an extended period of time can deplete the body of biotin.  Foods that are high in biotin include egg …

Adiponectin levels, food choices, and genetics

food-choices

Adiponectin, a hormone discovered in the 1990’s, is secreted by adipose (fat) tissue.  It is an anti-inflammatory protein, protective against the effects of low-grade inflammation that are associated with obesity.  Although it is made in fat tissue, those who have more fat tissue usually have lower adiponectin levels.  It is thought that the lower adiponectin levels (and …
