Arousal & Chocolate

Published:

Dear Dr. Myrtle,

Does chocolate actually has an effect on sexual arousal? How does it work?


Eat 4 ounces of 70% chocolate, and call me in the morning.

Looking for a quick, easy boost for your sexual arousal? Eat dark chocolate, (“straight-up” without other toffee, caramel, sugar-dense junk on it), every day in several doses. Not only will you have the opportunity to slow down and savor something pleasurable melting slowly in your mouth, making your salivary glands weep as that dense “food-of-the-gods” wraps itself around your tongue...

...you’ll also be giving your arousal system a boost in one of the most important ways possible. You’ll be tuning and spiffing up the little cells inside of your body that are the well-springs of your sexual arousal.

The Scoop on Sexual Arousal

(Jump ahead for those who just want the quick and dirty chocolate prescription.)

In a nutshell, sexual arousal depends upon two different things functioning: your nerves and your blood vessels. The nerves have to be healthy enough to transmit pleasure information to and from your brain, skin, genitals, ears, eyes--all over, really. When the brain is willing to be sexual and this information begins zinging around your nervous system, its next influence is on small little blood vessels in your genitals.

Untidy Habits Kill Sexual Arousal

Everything would be fine if we cared for our little blood vessels, but most of us are pretty poor custodians. Frankly, most of us are slobs on the inside. We eat “junk food”. We don’t bother with diets that include “vessel vacuum cleaners”: healthy, vessel-protective substances that could allow our capillaries to function more effectively. But blood vessel dysfunction is not only due to little clogged-up vessels: we’re also poisoning the inside of our little vessels. We breathe in toxic air pollution (including smoking). We neglect healthy workouts, all while living our lives of quiet desperation, stressed out and angry at that *@#* driver ahead of us. (Sheesh.) Then, we expect our blood vessels to perform sexual miracles?

To be healthy, blood vessels need to be supple and flexible, so they can transport vital fluids to other parts of our body. When the vessels are poisoned, their inner lining, something called “endothelial cells,” can’t work properly, and become underfed, under-exercised and inflexible. Stiff, really.

Now I know this seems contrary, but “stiff” is bad for sexual arousal. (I know you’re thinking stiff = hard[on], but nothing could be further from the truth.) Flexibility is critical to blood vessels being able to swell and transport fluids here and there. Fluids flowing and getting temporarily trapped in the genitals is the cause of that stiff and swollen experience.

So, daily exercise combined with diets containing predominantly fruits and vegetables, good oils (olive, canola, etc.) non-beef protein sources, good and varied amounts of spices and herbs, and allowing yourself only a smattering of white things (flour, sugars, etc.) is a SEX-HEALTHY way to live.

What’s Chocolate Got to Do, Got to Do With It?

Consuming dark chocolate on a daily basis can boost your sexual arousal potential. If there was one food that you could eat in moderation, was enjoyable to consume, left you feeling satisfied, happy and relaxed, that can be manufactured in a way respectful to the earth and the people processing it, you would eat it, right? And, what if this same food actually REVERSED some of the negative effects of some of our other life choices (smoking damage to blood vessels), lowered our bad cholesterol, helped our healthy insulin system work more effectively, and stripped our dangerous sugar peaks out of our lives? You’d eat it, right?

Chocolate, the partially fermented fatty seed of the cacao tree, is this impressive wonder food, determined to be the “food of the gods” by Mayan leaders. Multiple studies (1,2) have shown intriguing leads into understanding that there are positive effects from diets rich in dark chocolate. In addition, research in a leading heart research magazine (3) confirms that chocolate has direct positive effects on enhancing the flexibility and function of the “endothelial layer” of small blood vessels - even in participants who smoked cigarettes. The endothelial layer, the inner layer of a blood vessel, itself secretes a gas (nitric oxide) which inhibits irritation (inflammation) and destruction (oxidation) of the lining, and keeps all the cells healthy and in their proper place. Without this protection, the cells can’t work properly, so blood can’t flow through. If blood can’t flow through the little vessels, then no amount of sexual information coming in through the nerves will cause sexual arousal/engorgement (swelling) to occur. The importance of endothelial health to sexual arousal has been underscored by multiple studies, both for healthy persons , (4,5), and people with heart disease, high blood pressure, and diabetes (6,7). Poor blood flow, by itself, can further cause damage to parts of the body which swell with sexual arousal (clitoris/cavernosal sinus’)(8,9).

What’s Chocolate, but a second-hand dessert?

Unfortunately, there are many chocolate-negative messages to combat. Consider these facts:

  1. Regular chocolate consumption suppresses chocolate cravings (10).
  2. Dark chocolate improves glycemic control, allowing insulin and blood sugar to work at lower levels. (11,12)
  3. Eating chocolate infuses PEA & theobromide into our blood streams for a light, positive buzz.
    • Phenylethylamine--a neuromodulator “love hormone” in the adrenaline family--helps us feel sexy, alive, and loved.
    • Theobromide--a methylxanthine--causes mild mood elevation without an increase in stress, also enhances our parasympathetic/cholinergic system which enhances early sexual arousal into our blood.
  4. Eating chocolate releases endorphins (pleasure neuromodulators) into our systems. Other things that do this are:
    • ribald laughter,
    • acupressure and acupuncture,
    • warm hydro-massage,
    • exercise.
  5. Although chocolate contains caffeine, a very large study again confirms that chocolate does NOT cause heart arrhythmias (13).
  6. Although sugar is associated with some types of cancer (14), chocolate itself is anti-inflammatory (15). Don’t eat “milk” chocolate; eat the good stuff that’s at least 70% cacao, or nothing!
  7. Long-term diet studies of chocolate-consuming men show that their chances of dying of heart disease were cut in half. The more chocolate they ate, the higher the blood system health benefit (16).

Your Mother was Right.

If you want to experience the positive sexual benefits of chocolate consider the following guidelines:

  1. Clean your room.
    • Regularly eat chocolate: for fairly tidy people, you can get away with 1-2 oz 70% chocolate per day. Split this dose into several small doses each day, and it won’t seem so much.
    • For not-so-tidy bodykeepers, consider increasing your chocolate to 3 to 4 ounces per day (in split doses). Do be tidy about only eating the 70% chocolate, and don’t cheat by eating commercial candy bars colored with chocolate (those don’t count as good).
    • When you feel the need to knosh on something sweet, eat a small square of 70% dark chocolate. You’ll suppress your appetite, and you’ll be doing your blood sugar a favor.
    • Try to eat at least 60% cacao. If the item in question doesn’t list the “% cacao”, or “% cocoa solids” don’t eat it. Save yourself for a higher goal.
    • Become a health snob on your sex life’s behalf: turn away from milk chocolate. Gift those chocolate bunnies to somebody else. Resist, resist, resist milk chocolate.
    • Never, ever eat “white chocolate” again. This fake “un-chocolate”, reverses all of your good chocolate habits.
  2. Stop Smoking.
    • Although chocolate can reverse some of the short term damage smoking can bring to your blood vessels, imagine your sexual prowess if you never smoked at all.
    • You puff, and Mr. or Ms. Willy takes a hit. (In other words: your arousal & erections are gonna go bye-bye.)
  3. Eat colorful fruits and vegetables.
    • Cacao, after all, is the fermented fruit of the Theobroma cacao tree. The unique health benefits likely come from two features: the antioxidants in the fruit seeds, and the high cacao fat content which allows these antioxidants to penetrate and protect cell membranes.
    • Likewise, colorful fruits and vegetables have different kinds of antioxidants which protect different kinds of cell parts.
    • In general, the more color, the more antioxidant available. Raw or lightly-cooked food maintains more of the healthy components.
    • When shopping for your healthy chocolate source, please buy organic or sustainable chocolate. This helps us keep the beautiful birds in the air (since they live in the cacao trees).

Take Care and pass the chocolate,

Dr. Myrtle
