Mom always said broccoli was good for you … and she was right! The disease-fighting power of broccoli, combined with its low cost and availability, makes this cruciferous vegetable a top pick for an anti-cancer diet!
Even better is that the primary health benefits of broccoli are available to you by consuming a meager half-cup serving every day. It is naturally high in fiber, anti-inflammatory, detoxifying, and boasts powerful antioxidant content.
- Glucoraphanin, gluconasturtiian, and glucobrassicin are three phytonutrients in broccoli that help to detoxify your body at the cellular level.
- Dominant flavonoids kaempferol and quercetin boost your resistance to allergens, lower inflammation, and fight the ravages of free radicals caused by oxidative stress.
- Carotenoids such as lutein, beta-carotene, and zeaxanthin go above and beyond to protect you from the natural process of oxidation that gets out of control with our poor diet and lifestyle.
- Cancer stem cells don’t stand a chance against the sulforaphane content of broccoli! This compound has been studied extensively in the scientific community, and researchers are astounded by its effect on the development of cancer.
The nutrient density and low glycemic index of broccoli make it an excellent, low-calorie food for people on any health regimen – even diabetics and patients recovering from a heart event!
Broccoli Benefits: A Nutritional Powerhouse
Broccoli is a true nutritional powerhouse, delivering an impressive array of vitamins and minerals in every serving. It is exceptionally rich in vitamin K and vitamin C — two nutrients essential for bone health and immune function — while also providing vitamin A, vitamin E, and a full spectrum of B vitamins including folate and choline. On the mineral front, broccoli offers manganese, potassium, chromium, and copper, all wrapped in a generous serving of fiber. This remarkable combination makes broccoli one of the most nutrient-dense vegetables you can put on your plate.
Your digestive system, immune system, and cardiovascular system all gain a serious advantage when you add this cancer-fighting cruciferous vegetable to your meals. At 89% water, broccoli also helps hydrate your body as you eat. The fiber in broccoli protects your gut by giving beneficial bacteria the environment they need to flourish — and good gut flora are the key to flushing toxins out of your body as efficiently as possible. Broccoli’s extremely high levels of vitamin K promote strong bones and healthy blood, while its iron content is crucial for delivering oxygen-rich red blood cells throughout your body. Your heart will beat with joy at the significant potassium load as well. Out-of-control toxins and contaminants cause chronic inflammation — a primary risk factor for most forms of cancer. That means every food that aids in “sweeping up” these offenders helps you stay strong and cancer-free while giving you a powerful edge against heart disease, obesity, diabetes, and so much more.
Grow “Baby Broccoli” in Your Kitchen!
Consider broccoli sprouts. Broccoli less than three days old offers 50 times the cellular protection and 100 times the detoxification effect of fully mature broccoli. These tiny greens are one of the most potent cancer-fighting foods on the planet.
Similar in appearance to alfalfa sprouts, broccoli sprouts can be grown right on your kitchen counter with minimal equipment. No garden. No special lighting. Just a jar, some organic seeds, and a few days of patience. Dr. Joseph Mercola recommends using organic seeds and eating the sprouts raw for the best results — heat can destroy the powerful enzyme myrosinase, which is essential for converting sulforaphane into its active, cancer-fighting form.
Add a handful to salads, sandwiches, smoothies, or eat them straight. A little goes a very long way.
How to Prepare Broccoli to Retain the Most Health Benefits
If you must cook your broccoli, lightly steam it to keep the antioxidants intact. Never microwave your antioxidant-rich foods — studies have shown that microwaving can destroy up to 97% of flavonoids and other protective compounds. Raw is always best to get the full nutritional and anti-cancer benefits of broccoli. But if cooking, here is how to retain the most nutrients:
- Cut up organic broccoli a few minutes before cooking. This “prep time” activates the plant’s defense mechanisms, increasing levels of beneficial compounds such as sulforaphane.
- Bring two cups of water to a boil in a medium saucepan.
- Using a steaming basket, add broccoli and steam for approximately 5 minutes. The florets will turn bright green, and the texture will be “tender-crisp” — not mushy.
- Serve immediately with a sprinkle of coarse sea salt or a drizzle of cold-pressed olive oil.
Whenever possible, choose real food over supplements. Synthetic versions of vegetables are not the same, and your body knows the difference. While you may get some benefit from supplements, most are poorly absorbed compared to whole, living foods. No pill has ever matched the synergistic power of a fresh head of broccoli or a handful of sprouts.
Eat Your Way to a Cancer-Free Life!
When you follow a cancer-free lifestyle, you automatically lower your risk of many other serious diseases that claim the lives of millions every year — including heart disease, diabetes, obesity, and neurodegenerative conditions.
Your diet is a crucial aspect of total body wellness. Choose wisely and shop responsibly, opting for local and organic whenever possible. Eat real food — not processed, not packaged, not lab-made — and reap the benefits for decades to come.
Your body is counting on you. Every meal is either feeding disease or fighting it. Make your next meal a cancer-fighting one. Start with broccoli.

I use broccoli sprouts on my celery, carrot, and tomato and lettuce juice. I even even broccoli occasionally. My lunch was just broccoli boiled in water and coated with plant-based butter not butter coming from an animal and that was a whole meal for me.
