Potential Health Benefits of Arugula 

Arugula’s high nutrient content may contribute to a wide range of health benefits. They may improve everything from bone strength to brain health. In this part, we review some noticeable benefits of adding arugula to your diet. 

1. May Aid in Lowering Cancer Risk 

This potential health benefit is due to the following: 

• Presence of Antioxidants in Arugula 

Arugula is loaded with antioxidants, vitamin C, and carotenoids like lutein and zeaxanthin. These antioxidants help to protect your body from free radical damage. These unstable molecules can lead to cell damage and contribute to chronic diseases like cancer. 

• The Role of Cruciferous Veggies in Preventing Cancer 

Being a cruciferous vegetable, arugula has glucosinolates. These are sulfur-filled compounds which break down into isothiocyanates. These include sulforaphane. Research shows that sulforaphane can halt the growth of cancer cells and lessen the formation of malignant tumors. By consuming arugula and other cruciferous veggies often, you may lower your risk of developing different kinds of cancer. However, more research is required to confirm the claim. 

2. Might help in Preventing Osteoporosis 

This proposed benefit is due to the following: 

• The Link Between Vitamin K and Bone Health 

As we have said, arugula is full of vitamin K, which is proposed to be vital to keep bones healthy. Vitamin K boosts bone density by helping to make proteins needed for bone structure and function. A good intake of vitamin K has been linked to a lower risk of getting osteoporosis and fractures as we get older. 

• The Role of Calcium in Strong Bones 

Arugula also has calcium. This crucial element is needed for making and maintaining strong, healthy bones. Eating calcium-rich foods like arugula may help your body keep bone mass. This then reduces the risk of osteoporosis and bone fractures. 

3. Might Help in Managing Diabetes 

• Low Glycemic Index 

Arugula has a low glycemic index. This means it’s less likely to cause spikes in blood sugar compared to high-glycemic foods. A diet rich in low-glycemic foods may help people with diabetes manage their blood sugar levels better and lessen the chance of complications. 

• Fiber and Blood Sugar Control 

The fiber in arugula also may aid in controlling blood sugar levels. Fiber slows the absorption of glucose into the bloodstream. This helps to keep blood sugar levels steady throughout the day. Eating fiber-filled foods like arugula may offer added benefits for people managing diabetes. 

4. Might Help in Promoting Heart Health 

• Reducing Blood Pressure 

Being a good source of potassium, arugula may play a key role in controlling blood pressure levels. Potassium works against the bad effects of sodium and helps support healthy nerve and muscle function. Including potassium-rich foods like arugula in your diet may help lower your risk of heart disease by keeping blood pressure levels healthy. 

• Managing Cholesterol 

The fiber in arugula also may aid heart health. It is proposed to bind with cholesterol in the gastrointestinal tract and remove it from the body. This reduces total and LDL cholesterol levels and lessens the risk of heart disease. 

5. Might Help in  Boosting the Immune System 

• Vitamin C and Strong Immunity 

Arugula is a top source of vitamin C, which is critical to a strong immune system. Vitamin C helps make white blood cells, which fight infections and diseases. Eating vitamin C-rich foods like arugula may help build up a powerful immune system. 

• Antioxidant Support 

Being rich in antioxidants, arugula helps protect your body from free radical damage and oxidative stress. This protection may lead to a stronger immune system, better equipped to fight off infections, inflammation, and disease. 

6. Might Help Support Cognitive Health 

• Protecting the Brain 

Arugula’s high folate, nitrate, and antioxidant content may boost brain health and cognitive function. One study published in the Neurology journal found that eating just one cup of leafy greens each day may slow cognitive decline tied to aging. 

• Lowering Inflammation 

Arugula’s powerful antioxidants also aid the body in fighting inflammation. Chronic inflammation can contribute to illnesses and cognitive decline. Including arugula in your regular diet may offer protection against age-related cognitive decline and brain-attacking conditions. That could include Alzheimer’s and Parkinson’s diseases. 

7. Might Help Vision Support 

• Vitamin A and Eye Health 

Arugula is rich in provitamin A carotenoids. These may contribute to healthy vision and overall eye health. Vitamin A also may aid the immune system and keep the kidneys, lungs, and heart working well. 

• Antioxidant Effects on Vision 

As a good source of lutein, arugula may protect your eyes and keep your vision sharp. It blocks harmful UV light and might prevent age-related macular degeneration. Macular degeneration is a common cause of blindness and vision issues. 

Evidence of all these above-mentioned potential health benefits of arugula is continually being collected. Some studies have been conducted showing these benefits while more probing is required
