Kesan Akibat Kekurangan Vitamin D

Assalamualaikum!


Tahukah anda, vitamin D bukan sahaja baik untuk tulang anda (membantu penyerapan kalsium), tetapi ia juga baik untuk kesihatan jantung, mengurangkan risiko kanser, depression dan macam-macam lagi..


Di sini saya share satu artikel tentang Vitamin D...

Vitamin D and Your Bones



Vitamin D allows your body to absorb calcium. Without it, your bones can become brittle and weak. In adults, too little vitamin D can lead to malformed bones and osteoporosis.  In children, vitamin D deficiency once caused many cases of rickets, a bone disease and a major public health problem in the U.S. Fortifying the milk supply with vitamin D virtually eliminated the disorder.

Vitamin D for Heart and Mind



Low blood levels of vitamin D may have effects beyond your bones. Studies find a greater risk of heart problems and a greater risk of depression in older adults with low levels of vitamin D. And though it's not clear why, people taking a vitamin D supplement were 7% less likely to die than those who didn't take a daily supplement in one study. In children, researchers have found more severe asthma when vitamin D levels are low.





Who's at Risk for "D" Deficiency?




Studies find vitamin D deficiency can affect adults, infants, children, and adolescents. Your diet may increase your risk if it's low in milk or the foods that naturally contain vitamin D, such as salmon and eggs. Most people with low blood levels of vitamin D don't notice any symptoms. Others risk factors include:
  • Obesity
  • Digestive disorders like celiac disease
  • Older age (50+)
  • Some medications

Blood Pressure and Vitamin D


The combination of high blood pressure and vitamin D deficiency could be deadly. In one observational study, people with hypertension and a vitamin D deficiency were twice as likely to have a cardiac event than other people in the study. The lack of vitamin D was not linked to cardiovascular problems in those without hypertension.

Vitamin D and Breast Cancer


Low vitamin D may worsen the prognosis for women with breast cancer. In one study, women deficient in vitamin D when they were diagnosed had a 94% greater chance of the cancer spreading. They also had a 73% greater chance of dying over the next 10 years. Other studies suggest that vitamin D may even offer protection against developing breast cancer.

Vitamin D and Other Cancers


Vitamin D may offer some protection against at least two other cancers: colon cancer and prostate cancer. But vitamin D isn't a magic bullet. The cancer-fighting benefit may be limited to people who are otherwise healthy, not overweight, and exercise.

Vitamin D and Weight Gain


After menopause, most women gain weight until they reach their mid 60s. There is evidence, though, that taking a vitamin D and calcium supplement may slow that weight gain. In one study, women who were not getting enough of those two nutrients at the start were 11% less likely to gain weight and more likely to maintain their weight or even lose weight as a result of taking the supplement.

Vitamin D and Children


Evidence shows that children who get adequate vitamin D, either from the sun or from supplements, may have a reduced risk of developing type 1 diabetes. Studies also link inadequate vitamin D to more severe childhood asthma. Children with asthma who have low vitamin D levels have more hospitalizations and use more asthma medications.

How Much Vitamin D Do You Need?


How much vitamin D you need depends on your age and risk factors. The recommended dietary allowance is 600 IU per day for adults up to 70, and 800 IU for ages 71 or older. Some researchers have suggested much larger doses of vitamin D for a variety of health benefits, but too much may harm you. Above 4,000 IU per day, the risk for harm increases, according the Institute of Medicine.
