Broccoli sprouts are a powerhouse of nutrients that have all sorts of health benefits, particularly for cancer patients.
Along with all the other cruciferous vegetables, like cauliflower, broccoli, rocket (arugula), radishes and a number of others broccoli sprouts contain an enzyme called myrosinase that’s released when they are damaged in some way like biting them.
This enzyme breaks down glucosinolates into their active forms. One group of those is isothiocyanates. Isothiocyanates in turn activate other enzymes that can break down and remove toxic chemicals that can cause disease.
Broccoli sprouts contains large amounts of a particular glucosinolate which breaks down to sulforaphane. They have up to 100 times the amount of sulforophane as mature broccoli, depending on how fresh they are, which makes them a particularly valuable source of it.
Sulforophane has been shown to work on breast, prostate, colon, lung, oral, bladder, liver, stomach and skin cancers.
Its functions include inhibiting enzymes that can convert compounds into carcinogens and also removing carcinogens from the body.
Sulforophane can also affect your genes. The science of epigenetics is fairly new but genes can be switched on and off, which affects whether they do their job or not. It’s important for the right genes to be switched on and off.
Sulforophane can switch off genes with mutations, such as the BRCA gene mutations, and protect against disease.
Breast cancer
In a small and fairly short trial, sulforaphane found some positive but not statistically significant changes in tumor biomarkers that are usually used to detect improvements in cancer development (1).
Cancer stem cells are crucial to the development and recurrence of breast cancer. A mouse trial found that sulforophane eliminated stem cells (2). This has profound implications for protecting against breast cancer recurrence.
Another exciting mouse trial found that if a pregnant female ate broccoli sprouts regularly, it has a protective effect against breast cancer in her infant. This works via the epigenetic effect of sulforophane mentioned above (3).
Prostate cancer
Mice with prostate cancer were fed broccoli sprouts for 16 weeks. At the end of the trial, the researchers found that their cancers showed a significant reduction in growth (4). A very small human trial of men with recurrent prostate cancer didn’t have quite such spectacular results, but their PSA results did improve. Their PSA doubling time was significantly increased too. The researchers hoped to try it again with higher doses (5).
Colon cancer
Mice given a carcinogen were then fed broccoli sprouts. Normally they would have suffered colitis leading to colon cancers, but those on the broccoli sprout diet had less colitis and tumors (6).
In a human placebo-controlled trial, they were asked to eat 20 g a day of broccoli sprouts for 2 weeks to test the effect on their gut bacteria. The researchers found that the broccoli sprouts increased certain bacteria that are known to produce butyrate, which protects the lining of the colon from cancers (7).
Lung cancer
In 2005, a trial was conducted on mice to see whether sulforaphane could reduce lung cancers caused by tobacco. The results were positive and the researchers suggested that it should be tested on smokers and ex-smokers with early stage tumors (8).
Air pollution is considered to be another risk factor for lung cancers. So a trial was conducted in a particularly polluted area of China to see whether broccoli sprouts could help to detoxify people of the carcinogens in the air. They found that the sprouts worked very quickly and consistently to remove the carcinogens from the trial participants’ bodies, showing that they could have a protective effect against air pollution (9).
Oral cancer
In a review in 2016, they looked at a mouse trial, a laboratory study and a small human trial that aimed to discover whether sulforophane could protect against oral cancers. Mice that were predisposed to oral cancers had far fewer tumors after taking sulforophane than those who didn’t.
In the laboratory study, human neck and head cancer cells treated with sulforophane produced a protein that helped to detoxify carcinogens. In the human trial, healthy participants were asked to swish around their mouths fruit juice mixed with broccoli sprout extract for a few days. They produced the same protective detoxifying protein (10).
Bladder cancer
In another animal study, this time rats, who had been dosed with a carcinogen designed to cause bladder cancer, were given broccoli sprout extract and again it showed protective effects (11).
In a laboratory study more recently, the researchers found that broccoli, its sprouts or their pure isothiocyanates helped to kill bladder cancer cells by inducing apoptosis (programmed cell death) and other mechanisms. They went on to study the effects in mice implanted with human bladder cancer cells, where broccoli isothiocyanates significantly reduced the growth of tumors (12).
Liver cancer
In Qidong, a city in China, they have the highest incidence of liver cancer in the world. Part of the problem is related to molds called aflatoxins that are found in contaminated foods such as corn, which are known to be associated with liver cancer carcinogenesis.
Researchers tested an infusion (‘tea’) made from broccoli sprouts on 200 healthy adults and then measured the amount of aflatoxin in their urine. The results varied widely, as it seems that some people absorb the sulforophane more easily than others. But in the high absorber group, there was a significant level of aflatoxin excreted, suggesting that this is a good way of protecting at least some of the people in the area from liver cancer (13).
Stomach cancer
The rate of stomach cancer increases up to 6-fold in people who carry the H. pylori bacterium. It tends to cause gastritis and the resulting inflammation can lead to stomach cancer.
A placebo-controlled clinical trial in Japan, where rates of H. pylori infection are particularly high, involved a group of people who were infected. They were asked to eat 100 g of broccoli sprouts each day for 2 months.
The levels of H. pylori were substantially lower in the group eating the broccoli sprouts, as was the degree of gastritis. The bacteria were not completely eliminated, though. But the researchers suggested that broccoli sprouts would be a useful intervention to reduce the risk of stomach cancer (14).
Skin cancer
Hairless mice that were exposed to UV light twice a week for 20 weeks were subsequently treated topically with a concentrated broccoli sprout extract 5 times a week for 11 weeks. In the placebo group, all of the mice developed skin cancers.
However, in the concentrated broccoli sprout group only half of them got skin cancers and they were about half the size of the placebo group’s (14). It’s interesting that it wasn’t used as a sunscreen but after sun exposure to reduce the UV’s damaging effects.
Other health benefits of broccoli sprouts
- Helping prevent and fight cancer
- Supporting strong bones
- Helping fight H. pylori infection
- Supporting a healthy heart
- Detoxifying the body
- Helping protect the brain
- Improving lung function
- Supporting MS patients
It’s very rare finding fresh organically grown broccoli sprouts because you don’t often see them in your local health food store or supermarket. Mostly, you’ll be able to buy them as supplements, but the fresh ones do have more nutrients than the supplements.
So, the best option is to grow your own sprouts or a more convenient way it’s our ready to drink Broccoli Sprout Juice “COME ALIVE”.
One shot (40ml) of “COME ALIVE” Broccoli Sprout Juice is equivalent to 70gr of 3-4 days old fresh broccoli sprouts and 1.5kg of mature broccoli. Our juice is organic certified, raw-cold pressed (HPP), vegan and 100% safe from pathogen microbes and mold.
