I’ve reached the conclusion that genetics tests are useless, at least for me. They seem to be nothing but correlations.
For instance, I gained 20+ pounds eating a high saturated fat diet. So I had a genetics test done, which would supposedly tell me if I was susceptible to gaining weight on a high saturated fat diet. The result? I did not have that set of genes. But I still gained a ton of weight, so those genes are suspect.
Then, from the same company, they tell me that I am not more likely (edit: I’m less likely) to get bitten by mosquitos according to genetics. Bwahaaaahhaaahhaa! I am the very first person bitten. When to St. Croix some 10+ years ago, came back covered in mosquito bites. No one else had any or had very few.
Uploaded my data to another, supposedly much more comprehensive place, which even does recommendations for vitamins and minerals. I get the “free” version, which only allows a few complete reports. One report says I am likely to be more anxious than 98% of people. This is completely wrong. While I do get anxious at times like public speaking, in general, I am – and always have been – basically not anxious. Decided I was going to go in the Navy when I was 17, and went. No second thoughts, no anxiety. Decided I was going to move to Arizona after the Navy (was living in California), no anxiety about this at all. Just did it. Decided I was going to move from Arizona to New England without knowing anyone. Just did it.
Then there’s the whole MTHFR gene. Here’s 23 and Me’s position on it:
If what they are is a bunch of correlations, is there any benefit to them?
