Testosterone is the primary male sex hormone that's absolutely crucial for things like building muscle mass, strengthening our bones, improving our memory and mood, and of course increasing our sex drive and libido. And while certain foods like oysters pomegranates and Ginger can all help boost testosterone there are also certain foods that will hurt your body's ability to effectively produce testosterone and consistently eating these Foods overtime can even lower your testosterone levels. And low testosterone can lead to a chain of negative side effects including a loss of muscle mass insomnia increased body fat, depression, and low sex drive. So today I want to go over 7 foods that can hurt your testosterone levels based on scientific evidence. Starting first with flax seeds. Now I know that flaxseed products have gained a lot of popularity over the last few years and some have even called them a superfood. However even though flax seeds are very high in fiber and ala omega-3 fatty acids, flax seeds aren't that great for optimizing male hormonal health mostly because they're loaded with lignans. In fact, they're the world's richest source of lignans. Flax seeds contain about 75 to eight hundred times more lignans than most grains legumes fruits and vegetables. (1) now, this can be a problem for two reasons. First is that lignans are highly estrogenic. In other words, they increase levels of the female sex hormone estrogen. (2) Second is that lignans increase levels of sex hormone-binding globulin or shbg (3). Now, this may sound like a good thing but this hormone binds to free testosterone molecules rendering them inactive. So the testosterone won't be able to be used for other beneficial hormonal functions. We can see the direct adverse effects of flax seeds in a number of studies. For example, just 2 tablespoons of flax seeds were given to 40 male participants for only a month and their testosterone levels drop by around 10 percent. (5) In another very small but also very interesting study a woman who had high testosterone levels was also experiencing excessive facial hair growth. So to combat that researchers told her to eat 30 grams of flaxseeds per day for 4 months. after doing that her serum testosterone levels dropped by 70% and her free testosterone dropped by 89 percent. (4) In another study, two tablespoons of flaxseed per day dropped total testosterone in men by around 15% and free testosterone by 20 percent (6) however it's important for me to mention that the participants were also told not to get more than 20% of the daily energy intake from fat and a low-fat diet could've contributed to a reduction in testosterone levels as well. In either case, if you want to maximize your testosterone levels you're better off going with other sources of omega-3 fatty acids like salmon fresh sardines and walnuts.
Let's move on to cooking oils that are high in polyunsaturated fatty acids. These include things like soybean oil vegetable oil corn oil sunflower oil and margarine just to name a few. Most cooking oils used today are processed so many times they go through either bleaching, degumming, or deodorizing. Couple this with the fact that these oils aren't that great for high-temperature cooking and you'll see why they're not the best choice for your health. But even if you don't use them for cooking their high content of specifically omega 6 polyunsaturated fatty acids hurt the production of testosterone. This is because most people nowadays already get way too much omega-6s and way too little omega-3s. Not only does this create inflammation throughout the body and increase your risk of various chronic diseases but a high omega 6 polyunsaturated fat intake may lower testosterone. (11) in a study where researchers look at how different nutrients influence hormonal health, they found that the more dietary fat the participants ate the higher their testosterone was. (12) this was found to be true for they're saturated fat intake (13) as well as they're monounsaturated fat intake. (14) However, the results were the exact opposite for polyunsaturated fats. The more polyunsaturated fat that the participants ate in relation to their saturated fat intake the lower their testosterone levels dropped. (15) so if....
