In the largest research of its type, a Harvard University study has shown that without a doubt that the adherence to an unhealthy high fat typical Western diet is associated with impaired testicular function. Fertility expert Professor Allan Pacey of Sheffield University told the Independent that the results were almost certainly “down to an effect that those with the better diets are taking in more antioxidants.”
The research recently presented at the European Society of Human Reproduction and Embryology (ESHRE) annual meeting in Vienna, examined about 3,000 healthy young Danish men having a compulsory medical examination to determine their fitness for military service in the period 2008 to 2017.
The research conclusively showed that the SAD diet (the Standard American Diet) is indeed very sad when it comes to fertility.
Avoid red meat, processed food and starchy carbohydrates to be fertile
Those who ate a lot of red and processed meat, pizza, chips and sugary drinks tended to ejaculate an average of 25.6 million fewer sperm than those on a healthier diet.
But the study did not specifically look at a vegan diet. The healthiest category in this study was certainly not vegan and was dubbed a “prudent” diet comprising of fish, chicken, vegetables, fruit, and water. The category was not too dissimilar to the so-called Mediterranean diet.
The second highest sperm count was found in the vegetarian group whose diet did include soy and eggs.
With fertility rates declining in the western world by some 60% since the 1970s, this is another wake-up call to change dietary patterns away from the SAD diet towards something far more nutritionally sound. A decline of diet quality has accompanied the drop in fertility
A Scandanavian diet high in processed meats (“smørrebrød”), whole grains, cold fish and dairy came in the third position above the standard diet which came in last.
