Erectile dysfunction (ED), also known as impotence, is the inability to achieve or maintain an erection sufficient for sexual activity. It is one of the most common health issues among men. Today, it’s estimated that about 30 million men in the U.S. and more than 100 million men worldwide suffer from erectile dysfunction (ED). A large US survey found that roughly 50% of men between the ages of 40 and 70 experience some degree of ED.
Men with ED are known to have a higher risk of heart attacks and strokes. That’s why ED is often referred to as a “canary in the coal mine” for cardiovascular health—it may be an early warning sign of underlying vascular problems.
Oral medications like Viagra, Levitra, and Cialis provide symptomatic relief for about two-thirds of men, but they do not address the root cause and are not a cure. These medications also come with potential side effects and risks of adverse reactions. The only long-term solution is to address the underlying cause through diet and lifestyle changes. The good news is that these changes not only improve ED but also reduce the risk of future cardiovascular disease.
Adopting the PBWF/IF/10K lifestyle (a whole-food, plant-based diet combined with intermittent fasting and regular physical activity) has shown excellent results. This topic is briefly covered in the documentary Forks Over Knives and explored in greater detail in The Game Changers, which shows how a single high-fat, animal-based meal can significantly impair nocturnal erections.
The penis contains sponge-like erectile tissue that becomes engorged with blood during arousal. When a man is sexually stimulated, the brain sends signals that release the neurotransmitter nitric oxide (NO), which increases blood flow to the penis and causes an erection.
The most common cause of ED is poor blood flow. Contributing factors include alcohol, tobacco, and many medications—particularly those prescribed for high blood pressure, such as diuretics and beta-blockers. Although ED can also be caused by prostate surgery, neurological issues, or psychological factors, this discussion focuses on vascular causes.
Most articles on ED list high blood pressure, high cholesterol, obesity, and diabetes as risk factors. However, this can be misleading. These conditions do not directly cause ED—the same inflammatory, artery-clogging foods that cause these conditions also lead to ED.
We have previously discussed how atherosclerosis, caused by consuming inflammatory foods, narrows blood vessels and reduces blood flow. It also impairs the release of nitric oxide from endothelial cells, which line the inner walls of blood vessels. The penis requires healthy blood flow and adequate nitric oxide for proper function.
Nitric oxide is essential for achieving an erection. Disorders that impair its production or release are closely linked to ED. The enzyme nitric oxide synthase (NOS) produces NO from the amino acid L-arginine.
To address ED at its root, one must reverse atherosclerosis and repair endothelial function. This can be supported by increasing nitric oxide availability through dietary intake of L-arginine. Several plant-based foods are rich in L-arginine, including:
- Soybeans, pumpkin seeds, sesame seeds, peanuts, and walnuts
- Green bell peppers and spirulina
- Grains such as quinoa, oats, and wheat germ
To reverse atherosclerosis, the best nitrate-rich foods are green leafy vegetables and beets. We have previously discussed their benefits in detail.
VIAGRA: The Rest of the Story
The role of nitric oxide (NO) as a signaling molecule in the cardiovascular and nervous systems has been known since the 1980s. However, its clinical potential only began to unfold around the turn of the millennium. Dr. Louis Ignarro, a pharmacologist at UCLA, was at the forefront of this research and was awarded the Nobel Prize in 1998 for his groundbreaking work showing how nitric oxide helps open up clogged blood vessels.
Building on Dr. Ignarro’s discoveries, Pfizer—one of the world’s leading pharmaceutical companies—began developing a drug to treat high blood pressure and angina. During clinical trials for heart patients, researchers observed an unexpected side effect: the drug was significantly more effective at inducing erections than relieving angina. That serendipitous finding led to the development of Viagra. And now, you know the rest of the story.
Today, it’s estimated that about 30 million men in the U.S. and more than 100 million men worldwide suffer from erectile dysfunction (ED). A large U.S. survey found that roughly 50% of men between the ages of 40 and 70 experience some degree of ED.
Interestingly, what Viagra achieves temporarily can also be supported through long-term dietary choices. Regular consumption of nitrate-rich foods such as green leafy vegetables and beets has been shown to naturally boost nitric oxide levels, offering lasting cardiovascular and sexual health benefits.
