Apa Manfaat Kesehatan Selada Air?

Selada air kaya akan isothiocyanate yang dapat membantu mencegah kanker dan meningkatkan kekebalan tubuh. Nitrat dalam sayuran meningkatkan kesehatan jantung dan juga dapat meningkatkan kinerja fisik Anda. Nutrisi lain dalam sayuran ini dapat membantu mencegah osteoporosis dan membantu pengobatan diabetes.

1. Dapat Membantu Pencegahan Kanker

Selada air melawan spesies oksigen reaktif, dengan demikian membantu pencegahan kanker. Sayuran kucifer, termasuk selada air, mengandung senyawa organosulfur dan isothiocyanate yang berperan dalam hal ini (3).

Selada air juga ditemukan dapat menekan perkembangan kanker payudara. Ini bisa dikaitkan dengan phenylethyl isothiocyanate, senyawa dalam sayuran. Senyawa ini mengganggu fungsi protein yang berperan dalam perkembangan kanker payudara (4).

Senyawa ini juga ditemukan membantu mencegah kanker paru-paru pada perokok (5). Selada air juga ditemukan untuk meningkatkan efek terapeutik dari terapi radiasi kanker (6).

Selada air juga dapat berperan dalam pencegahan kanker kolorektal. Dalam sebuah penelitian, sekelompok populasi Selandia Baru dengan asupan selada air yang tinggi ditemukan memiliki tingkat kanker kolorektal yang rendah (7).

2. Dapat Meningkatkan Kesehatan Jantung

May Promote Heart Health
May Promote Heart Health

Reports suggest that nutrient-dense veggies, like watercress, are more likely to protect people from heart disease (2). Studies show that cruciferous vegetables, in general, have cardioprotective properties (8).

These green leafy veggies also contain nitrates, which promote heart health. Dietary nitrates lower blood pressure levels and prevent platelet aggregation. They improve endothelial function and exercise performance in individuals (9). Nitrates achieve this by reducing arterial stiffness and thickness and their inflammation (9).

In rat studies, watercress extracts could reduce levels of total cholesterol, triglycerides, and bad cholesterol (10). More human studies are warranted, though.

3. May Aid Diabetes Treatment

There is not a lot of research to support this claim. However, one study states that watercress may have a beneficial effect on serum glucose levels. The study conducted on diabetic rats found that extracts of watercress could lower the levels of both serum glucose and serum cholesterol. These effects, if replicated in humans, can have beneficial effects on individuals with diabetes (11).

People with diabetes also tend to have a higher risk of vascular disorders, including hypertension and neuropathy. The nitric oxide in watercress can help alleviate this (12).

The nitric oxide can also reduce the risk of other diabetes complications, like blindness and limb amputations (12).

4. Can Promote Bone Health

Rutin, a flavonoid found in watercress, was found to stimulate the formation of osteoblasts (cells that secrete the matrix for bone formation) (13). The vegetable was also found to stimulate bone mineralization, which is an important function to prevent osteoporosis.

The vitamin K in watercress also plays a major role in bone health. Deficiency of this nutrient has been linked to higher rates of osteoporosis and fractures (14).

5. May Boost Immune Function

In a study involving fish, watercress was found to boost immune function. The nutrients of watercress that contribute to its immune-boosting effects include vitamins A, B1, B2, and C, folic acid, iron, glucosinolates, and calcium (15).

Watercress showed similar effects in another study involving broilers. Including watercress in their diet could improve the performance and immune response of the broilers (16).

The vitamin C in the vegetable, in specific, also has beneficial effects on the immune system. 34 grams of watercress offers about 24% of the daily value of vitamin C. Vitamin C is known to boost immune function by promoting the production of white blood cells (17).

6. May Promote Athletic Performance

May Promote Athletic Performance

We have seen that watercress contains nitrates. There is some research that states that these nitrates may boost athletic performance. They relax your blood vessels and improve nitric oxide levels in the blood. This may promote athletic performance (18).

On the contrary, other research shows that watercress may have a negative impact on exercise performance (19). Hence, more research is warranted in this regard.

7. May Improve Skin Health

Watercress may help reduce skin inflammation. The use of watercress in the cutaneous inflammatory process treatment has been well documented. Interestingly, the use of watercress for treating skin inflammation may produce no adverse effects (as opposed to the conventional treatment methods) (20).

The vitamin A in watercress also contributes to skin health. It protects the skin cells from damage due to free radicals. The nutrient also boosts resistance to skin infections (21).

The isothiocyanates in watercress can prevent skin cancer too. These compounds interfere with malignant cells and restore normal cell function (22).

8. May Aid Weight Loss

Watercress is a nutrient-dense vegetable that is low in calories. Hence, one can include it in a weight loss diet. It would be a way of getting more nutrients with fewer calories.

Though there is no research citing the direct weight loss effects of watercress, you definitely can try including it in your weight loss diet.

Watercress is a humble veggie with an incredible nutrient profile. Including it in your regular diet would sure be a wise move. But how do you do it?

How To Incorporate Watercress Into Your Diet

Due to its tenderness, watercress sautés faster than most other greens. It also imparts a mild spice and tang to any dish it is added to. You can incorporate this veggie into your diet in the following ways:

  • Toss it into a salad. Include watercress in your evening vegetable salad. You can also eat it along with a delectable dash of pepper.
  • Add it to your wrap or sandwich. You can complement this with grilled cheese.
  • Add it your breakfast omelet or egg scramble.
  • Include watercress in your morning vegetable juice.

There is nothing that should stop you from eating watercress every day. But before you do that, you ought to know the potential adverse effects this vegetable may cause.

What Are The Potential Side Effects Of Watercress?

May Interfere With Thyroid Health

Most cruciferous vegetables, including watercress, contain compounds called goitrogens that may interfere with iodine metabolism. Iodine is a nutrient essential for thyroid health, and this interference may cause thyroid issues (23).

Individuals with thyroid issues may have to limit their intake of watercress (and other cruciferous vegetables) and consult their doctor.

May Aggravate Kidney Disease

Watercress contains potassium, though only in low amounts. Excess potassium may aggravate kidney disease (24). If you are dealing with kidney issues, please check with your doctor before adding watercress to your diet. Your doctor may suggest you limit consumption and even advice you on the right dosage.

Insufficient Information On Its Effects During Pregnancy And Breastfeeding

There is less information available on the safety of watercress during pregnancy and breastfeeding. Hence, please check with your doctor before you include the vegetable in your diet.

Conclusion

Now we know why watercress was a staple in the diets of Roman soldiers. Its potent antioxidants may keep diseases at bay and promote athletic performance. Adding it to your diet is quite simple. Be wary of its adverse effects, though.
