Fat, food and sex. Oh the joy of ignorance. I remember growing up in the 80’s and pretty much everything I ate came from a box. My mom was a single mom trying to raise us while working 2 or 3 jobs. Dinner was often Dinty Moore beef stew in a can, or On-cor frozen entrees like Salisbury steak or chicken parmesan. Or there was Suddenly Salad!, which wasn’t salad at all, but pasta in a bunch of oil and salty seasoning. I could enjoy them without knowing how all the fat and salt affected sexual function, compromising blood flow to the arteries of the clitoris. I didn’t realize until I was way older and concerned about my own pleasure in the bedroom that all that fat could affect my sex life.
Hyperlipidemia is when there is too much fat in the blood, which comes from eating a high fat diet. Women with hyperlipidemia had significantly lower arousal, lubrication, orgasm and satisfaction1. Eating fatty food causes our blood vessels to stiffen and makes the heart have to work extra hard to pump blood to the body. Even after one fatty meal, such as chicken and cheese in one study, the blood vessels become measurably stiffer a few hours later2. When blood vessels, arteries and veins are more elastic, blood is able to move more freely and the heart does not have to work as hard.
In addition to stiffening the blood vessels, fatty foods also cause build up in the blood vessels. In fact, the blood vessels going to the penis3 and clitoris4 are some of the smallest in the body. So, long before a person sees signs of heart disease, they will notice that sexual pleasure and function5 declines6. In fact, men who are diagnosed with ED in their 40’s are 50 times more likely to develop Coronary artery disease7. The good news is that even after damaging blood vessels with high fat, changes in diet can help normalize blood flow to the genitals8.
Plaque Accumulation
Plaque accumulation also restricts blood flow to the clitoris, making it more difficult for it to become fully engorged with blood. Clitoral vascular resistance means9 is that blood does not flow as freely in the clitoris. This increases with factors associated with cardiovascular disease such as weight and insulin resistance. Poor blood flow will make the clitoris less responsive to touch, making orgasm more difficult10.There’s, great news though! Changing your diet can actually reverse damage to these blood vessels caused by excessive fat intake11. Eat good food and sex will be better.
The fat-sugar combination:
The Fat Sugar Combination:
It seems that eating high fat plus high sugar is even worse for your blood vessels. There is a great deal of research showing that eating one high fat- high sugar meal results in immediate low-grade inflammation in our bodies and dysfunction in our blood vessels12. This is a temporary state, but when we chronically challenge our bodies with high fat and high sugar we damage blood vessels, making it more difficult for them to deliver adequate blood to the genitals.
So when we consider food and sex, we must make a conscious effort to limit dietary fat so that our blood vessels can deliver abundant blood to the genitals, for the best sex!

Hi there:
I don’t really get spam remarks, though honestly I am not savvy in web management. Good luck though!
Thanks so much for your kind words 🙂
