Research suggests that sulforaphane found in broccoli may protect the eyes from ultraviolet radiation. Studies show this antioxidant can help prevent blindness, reduce the risk of cataracts and macular degeneration, and protect against other serious eye diseases.
Furthermore, broccoli contains lutein and zeaxanthin, two potent antioxidants that positively affect vision. Broccoli is also rich in vitamin C, another nutrient essential for better vision.
All these nutrients work together to improve eye health and reduce the risk of age-related vision problems. Therefore, consuming a regular portion of boiled broccoli may be beneficial for maintaining healthy eyesight throughout life.
It may reduce the risk of cancer.
Cruciferous vegetables, such as broccoli, contain various bioactive compounds that may reduce cell damage caused by certain chronic diseases. These compounds have also been shown to help protect against certain types of cancer.
Namely, cruciferous vegetables have been associated with a reduced risk of breast cancer recurrence and mortality in breast cancer. They have also been found to decrease levels of estrogen metabolites associated with the risk for breast cancer.
In prostate cancer, cruciferous vegetables have been linked to lower prostate-specific antigen (PSA) levels in patients with localized prostate cancer. They have also been associated with a lower risk for advanced prostate cancer.
For gastric/stomach cancer, cruciferous vegetables have been found to lower the risk for gastric adenocarcinoma and other stomach cancers.
In colorectal cancer, cruciferous vegetables have been shown to decrease colorectal cancer mortality and inhibit the growth of colorectal tumour cells.
In renal/kidney cancer, cruciferous vegetables have been linked to a reduced incidence rate and mortality from renal cell carcinoma (RCC) and kidney tumours.
Lastly, cruciferous vegetables have also been associated with a decreased risk of bladder cancer.
However, it is important to note that while current data is encouraging, more human research is needed to confirm the relationship between cruciferous vegetables and preventing these cancers.
Supports hormonal balance
Studies have suggested that compounds in cruciferous vegetables, such as broccoli, may support hormonal balance. Broccoli contains phytochemicals, including sulforaphane and indole-3-carbinol (I3C), which may help to reduce the risk of endocrine-related disorders. These compounds can affect hormones by affecting the metabolism of hormone regulation or production enzymes.
In addition, these compounds may also be able to interact with estrogen receptors and modulate their activity.
Research suggests that consuming more cruciferous vegetables is associated with better hormone balance due to the presence of these active compounds. Furthermore, animal studies have indicated potential benefits for balancing hormones when consuming cruciferous vegetables such as broccoli due to their anti-estrogenic effects.
Therefore, eating a diet rich in broccoli could provide benefits for maintaining healthy hormonal levels.
It may support the immune system.
In addition to helping maintain hormonal balance, broccoli is also beneficial for supporting the immune system. Research shows that vitamin C, a key nutrient in this vegetable, plays an important role in preventing and treating illnesses. It can be obtained by consuming 100–200 mg of vitamin C daily.
Broccoli contains a wealth of this vital vitamin — just one-half cup (78 grams) provides 84% of the recommended dietary intake. Some health benefits related to its immune-boosting properties include:
- Increased Resistance: Vitamin C helps support white blood cells, which defend against bacterial and viral infections.
- Improved Healing Time: This nutrient has been shown to reduce inflammation and speed up wound healing by promoting collagen production.
- Enhanced Immune Response: Vitamin C helps boost immunity by stimulating the activity of natural killer cells responsible for attacking foreign invaders such as bacteria and viruses.
Overall, it’s clear that broccoli is a great source of vitamin C and, therefore, an excellent way to support your body’s natural defence mechanisms against illness.
Healthy Digestion and Reduced Constipation
Eating broccoli has been linked to improved digestion and reduced constipation. Studies have found that consuming a diet rich in fibre and antioxidants, like broccoli, can help maintain healthy gut function.
A study conducted on mice concluded that a broccoli-based diet led to lower levels of inflammation in the colon and beneficial changes in bacteria composition.
Additionally, humans who ate broccoli were reported to experience less difficulty defecating than those in the control group.
While these results are promising, more research is needed to fully understand how eating broccoli affects digestive health and reduces constipation.
