Don’t Eat a Bad Sex Diet. Avoid these Libido-Killers.

You won her heart with long-stemmed roses. Now what? Keep the post-Valentine’s Day doldrums at bay by steering clear of these foods. Every one of them is known to kill the sex drive.

Gin and tonic You already know about the effects of gin (I believe the proper medical terminology is whiskey dick), but did you know that tonic water also suppresses the libido? The quinine that flavors it is known to lower testosterone levels. Gin with tonic water is a double whammy in a highball glass.

Microwave popcorn Pop a bag and the nonstick chemicals used on the inner lining of the microwave bag are transferred to the popcorn you eat. The most commonly used of the chemicals contain substances that have been linked to testicular tumors, infertility, and lower sex drive.

Moroccan spices The Willams-Sonoma website describes its little jar of ras el hanout as ‘notable for its rich aroma and well-balanced curry-like flavor.’ Ras el hanout is even more notable for containing agnus castus, a spice better known as monk’s pepper or chaste berry, an ingredient prized in monastery kitchens for helping monks to maintain their vows of chastity.

Black licorice A simple movie date is a nice follow-up to the Valentine’s Day fuss, but skip the concession stand Good & Plenty. Black licorice contains testosterone-lowering phytoestrogens. Just the black. Have some Red Vines instead.

Mint Mint tea is a common homeopathic remedy prescribed for women with excess body hair. The mint oil in the tea (and other minty foods) makes the extra hair fall out by lowering the drinker’s testosterone. This is a good thing. Not so good for men who want to hang on to their testosterone and their hair.

And then there’s soy. Soy gets a special mention because it doesn’t belong on this list. For years it’s been getting a bad rap. The story goes that soy is loaded with estrogen; it will overwhelm your system with female hormones, your testosterone will plummet, your muscles (and more!) will start shrinking, and you’ll develop gynecomastia, a.k.a. man boobs. Not true. The misinformation stems from a lone test subject in a single study who apparently did grow breasts and did drink soy milk in ungodly amounts, but he also suffered from a host of other health and weight-related issues that were not widely reported but probably the true culprits.
