The Origins of Broccoli
Broccoli has a long and storied history. It originated in the Italian peninsula in ancient Roman times over 2,000 years ago. Broccoli is derived from wild cabbage plants that grew across the Mediterranean region. Through selective breeding over many generations, growers gradually cultivated it into an edible vegetable crop with densely bunched green flower heads.
The word broccoli comes from the Italian word broccolo which means cabbage sprout or shoot. Broccoli first became popular as a food in Italy during the Roman Empire. The Romans would eat the flowering shoots of broccoli which at that time resembled large green stalks with small flower buds similar to modern broccolini.
Broccoli Arrives in America
Broccoli did not make its way across the Atlantic Ocean to North America until colonial times in the 1700s. Thomas Jefferson helped introduce broccoli when he brought broccoli seeds back to Monticello after a trip to Europe. Commercial production started in the 1920s when Italian immigrants brought their broccoli recipes and seeds to the United States.
Today, California produces over 90% of broccoli grown in America, with about one million tons harvested annually. Broccoli has exploded in popularity over the last 50 years and is now one of the most widely consumed vegetables thanks to its rich nutrition and countless health benefits.

The Many Health Benefits of Broccoli
The unique combination of vitamins, minerals, antioxidants and phytochemicals in broccoli provide a wide range of health benefits. Broccoli has been extensively studied for decades and the research continues to show eating broccoli regularly can...
Boost Immunity
The Vitamin C content found in just a single cup of broccoli exceeds your daily requirements. Vitamin C stimulates the production of white blood cells and antibodies to fight against invading pathogens and infections.
Support Heart Health
Broccoli is rich in a compound called sulforaphane that research shows can help reduce LDL and total cholesterol to support cardiovascular function.
Aid Detoxification
The isothiocyanates in broccoli help upregulate phase 2 liver detoxification enzymes to assist with eliminating toxins from the body more efficiently.
Protect Skin Health
As an antioxidant-rich food, broccoli can help minimize oxidative stress to skin cells to reduce the effects of aging. Broccoli is also high in vitamin E critical for UV protection against sun damage.
The B vitamins in broccoli also prevents flaking of the skin and other symptoms associated with vitamin B deficiency.
Prevent Cancer
The sulforaphane found in broccoli may help suppress tumor growth by helping rid the body of cancer-causing chemicals. Multiple studies have linked eating cruciferous vegetables with a lower risk of cancers including prostate, colon, breast and lung cancer.
Build Strong Bones
The abundant vitamin K in broccoli plays an essential role in bone health by improving calcium absorption and reducing urinary excretion of calcium to prevent bone thinning.
Broccoli also contains magnesium, zinc and phosphorus needed for proper bone matrix formation to keep bones strong and prevent osteoporosis with aging.
Slow Aging Process
The antioxidants in broccoli like vitamin C and glutathione fight against free radical damage to cells. This antioxidant effect helps slow the aging process caused by oxidative stress contributing to neurodegenerative disease, vision loss and aging skin.
Support Eye Health
The zeaxanthin and lutein antioxidants found in broccoli may help prevent UV damage to the eyes as well as age-related macular degeneration (AMD) which can lead to blindness.
Boost Digestion
The dietary fiber content aids with digestion by promoting regularity and encourages growth of good bacteria in the gut microbiome. The sulforaphane in broccoli also seems to provide a protective effect on the gastrointestinal lining.
Strengthen Immunity
Broccoli has nearly 150% of your daily needs of immunity boosting vitamin C per cup. Vitamin C increases white blood cells to fight infections and helps shorten duration and severity of colds.
Potential Health Risks of Eating Too Much Broccoli
Most medical professionals consider broccoli to be very safe even when eaten in large amounts. However, there are some possible health risks to consider if you eat very high amounts of broccoli on a daily basis. These include...
Blood Thinning
The vitamin K content in broccoli could interfere with blood thinner medication. Anyone taking Coumadin or other anticoagulant drugs should keep intake consistent rather than suddenly increasing or decreasing daily amounts.
Kidney Stones
Broccoli does contain small amounts of oxalates which can contribute to kidney stone development in a small subset of people prone to this condition. But studies show broccoli more often helps prevent kidney stones.
Gas and Bloating
The fiber in broccoli, while beneficial for most people, may cause gas, diarrhea or cramping in some cases with digestive issues like IBS. FODMAPs in broccoli can also trigger uncomfortable bloating.
Thyroid Function
Like other cruciferous veggies, broccoli naturally contains small amounts isothiocyanates which could theoretically disrupt thyroid function in high amounts for people with hypothyroidism.
But human studies show normal broccoli consumption poses little risk unless you already suffer from thyroid problems. Cooking broccoli, rather than eating large amounts raw, can further reduce this concern.
