ផលប្រយោជន៍សុខភាពនៃមើម Fennel (Health Benefits Of Fennel)


fennel
Fennel is easily recognized by its pale bulb and long green stalks, and can be grown almost anywhere.
Excerpt from Medical New Today - What are health benefits of fennel?

Nutritional breakdown 

One raw fennel bulb contains only 73 calories, 0.5 grams of fat, 0 milligrams of cholesterol, 2.9 grams of protein, 17 grams of carbohydrate, and 7 grams of dietary fiber (28% of daily requirements).

The same serving provides 27% of daily potassium needs, 5% of sodium, 6% vitamin A, 11% calcium, 46% vitamin C, 9% iron, 5% vitamin B-6 and 10% of daily magnesium needs.

Fennel also contains phosphorous, zinc, copper, manganese, selenium, niacin, pantothenic acid, folate, choline, beta-carotene, lutein and zeaxanthin (vision), vitamin E and vitamin K.

In addition to all of these nutrients, fennel also contains dietary nitrates and is a natural source of estrogen.

Possible health benefits of consuming fennel

Bone health
The iron, phosphorous, calcium, magnesium, manganese, zinc and vitamin K content present in fennel all contribute to building and maintaining bone structure and strength.

Though phosphate and calcium are both important in bone structure, the careful balance of the two minerals is necessary for proper bone mineralization - consumption of too much phosphorus with too little calcium intake can result in bone loss.
Iron and zinc play crucial roles in the production and maturation of collagen.
Bone matrix formation requires the mineral manganese, and iron and zinc play important roles in the production and maturation of collagen.
Low intakes of vitamin K have been associated with a higher risk for bone fracture. Adequate vitamin K consumption is important for good health as it acts as a modifier of bone matrix proteins, improves calcium absorption and may reduce urinary excretion of calcium.5
Blood pressure
Maintaining a low sodium intake is essential to lowering blood pressure, however increasing potassium intake may be just as important because of its vasodilation effects. According to the National Health and Nutrition Examination Survey, fewer than 2% of US adults meet the daily 4,700 mg recommendation.4

In addition, potassium, calcium and magnesium (all present in fennel) have been found to decrease blood pressure naturally.6

Dietary nitrates present in certain foods such as fennel have been found to lower blood pressure and protect the heart due to their vasodilatory and vasoprotective properties. One study conducted by the Swedish School of Sport and Health Sciences showed that participants' blood pressure levels were lower after taking nitrate supplements that contained nitrate amounts equivalent to 150-250 grams of nitrate-rich vegetables than after taking a placebo.9

Heart health

Fennel's fiber, potassium, folate, vitamin C, vitamin B-6 and phytonutrient content, coupled with its lack of cholesterol, all support heart health.

Fennel contains significant amounts of fiber, which helps lower the total amount of cholesterol in the blood, thereby decreasing the risk of heart disease.

In one study, those who consumed 4,069 mg of potassium per day had a 49% lower risk of death from ischemic heart disease compared to those who consumed less potassium (about 1,000 mg per day).

Vitamin B-6 and folate prevent the buildup of a compound known as homocysteine. When excessive amounts of homocysteine accumulate in the body, it can damage blood vessels and lead to heart problems.

Cancer

Selenium is a mineral that is not present in most fruits and vegetables, but can be found in fennel. It plays a role in liver enzyme function and helps detoxify some cancer-causing compounds in the body. Additionally, selenium prevents inflammation and also decreases tumor growth rates.

Fiber intakes from fruits and vegetables like fennel are associated with a lowered risk of colorectal cancer.

Vitamin C, vitamin A and beta carotene function as powerful antioxidants that help protect cells against free radical damage.

Fennel also contains folate, which plays a role in DNA synthesis and repair, thus preventing the formation of cancer cells from mutations in the DNA.

Immunity

The selenium found in fennel has also been found to improve immune response to infection by stimulating production of killer T-cells.

Inflammation

Choline is a very important and versatile nutrient in fennel that helps with sleep, muscle movement, learning and memory. Choline also helps to maintain the structure of cellular membranes, aids in the transmission of nerve impulses, assists in the absorption of fat and reduces chronic inflammation.

Metabolism

Fennel is a source of vitamin B-6, which plays a vital role in energy metabolism by breaking down carbohydrates and proteins into glucose and amino acids. These smaller compounds are more easily utilized for energy within the body.

Digestion and regularity

Because of its fiber content, fennel helps to prevent constipation and promote regularity for a healthy digestive tract.

Weight management and satiety

Dietary fibers are commonly recognized as important factors in weight management and loss by functioning as "bulking agents" in the digestive system. These compounds increase satiety and reduce appetite, making you feel fuller for longer and thereby lowering your overall calorie intake.

Increasing iron absorption

Iron deficiency is one of the most common nutrient deficiencies in developed countries and a leading cause of anemia. Pairing foods like fennel that are high in vitamin C with foods that are iron-rich will maximize the body's ability to absorb iron.

Estrogen

Estrogen, which is found naturally in fennel, is crucial in regulating the female reproductive cycle and can also affect fertility. The University of Texas Southwestern Medical Center conducted a study on mice, which showed that estrogen also plays an important role in controlling factors that contribute to body weight, such as appetite and energy expenditure.8

Skin

Fennel is an excellent source of vitamin C. Collagen, the skin's support system, relies on vitamin C as an essential nutrient that works in our bodies as an antioxidant to help prevent damage caused by the sun, pollution and smoke. Vitamin C also promotes collagen's ability to smooth wrinkles and improve overall skin texture.

Consuming fruits and vegetables of all kinds has long been associated with a reduced risk of many lifestyle-related health conditions. Many studies have suggested that increasing consumption of plant foods like fennel decreases the risk of obesity and overall mortality, diabetes, heart disease and promotes a healthy complexion and hair, increased energy, overall lower weight.
