How do you know if you have vitamin D deficiency? What are the tell-tell signs of Vitamin D deficiency? Vitamin D is extremely important to our everyday well-being. Vitamin D is actually strictly not a vitamin itself, it actually behaves more like a hormone. Did you know, that every single cell in your body has a receptor for it? Vitamin D is produced naturally when your body is exposed to sunlight. You can also find it in certain foods such as fatty fish, fortified dairy products such as yoghurt and egg yolks; however more often than not it is very difficult to obtain the adequate amount in food alone. Because of this, vitamin D deficiency is common. Approximately, 1 billion people in the world have Vitamin D deficiency. So how do you know that you are vitamin D deficient? What are the key signs you need to look out for? - How often are you getting sick or feeling under the weather? Vitamin D’s most important role is to support your immune system so you can fight infections. If you get sick quite often, the lack of Vitamin D can be a contributing factor. - Are you feeling tired or exhausted on a daily basis? This sign often gets overlooked in our busy daily lives; however ignoring the feelings of fatigue can have a detrimental effect on your over-all physical and mental wellbeing. - How often do you complain of having back pain? As you may know, vitamin D helps your body absorb calcium and maintain the optimum bone health. A recent study done in the US found that those with a deficiency are more likely to suffer from back pain which can limit their daily activities. - Are you feeling blue? Depression and low mood has been linked to low vitamin D levels, and effective supplementation saw significant improvement in mood. - Is your hair falling out? Moderate to light hair loss is often associated with stress and poor diet. However, when hair loss is severe it is good to check your vitamin D levels. One successful study has shown that topical application of vitamin D was found to successfully treat hair loss in a young boy who had a severe defect I vitamin D receptors. - Are your muscles hurting? There is some evidence that shows that vitamin D deficiency may be a potential cause of muscle pain in children and adults. This might be due to the interaction between the vitamin and pain-sensing nerve cells. - Do you have darker skin? Your skin pigment acts as a natural sunscreen, so the more pigment you have, the harder kit is for your body to produce the adequate levels of vitamin D. Correcting vitamin D deficiency is easy. You can do it by altering your diet, adding a vitamin D supplement to your diet and spending a few more glorious minutes in the sun. But remember always to stay safe!

Debljina uzrokuje manjak vitamina D Poznato je da debjina utječe na utječe na razvoj dijabetesa tipa 2, srčanih bolesti i određenih oblika raka U nedavnom izdanju časopisa PLoS Medicine objavljena je studija koja upozorava da debljina može uzrokovati manjak vitamina D. Ova je studija, koju su proveli istraživači okupljeni u zajedničkoj suradnji pod imenom D-CarDia u okviru Britanske zaklade za srce (British Heart Foundation), prva povezala visok indeks tjelesne mase (BMI) s niskim razinama vitamina D. Studija je obuhvatila više od 42.000 ljudi iz 21 zemlje, a unutar nje istraživači su pokušali prepoznati sve genetske varijacije kojr bi mogle biti povezane s indeksom tjelesne mase i vitaminom D kako bi bili sigurni da nijedan drugi čimbenik nije utjecao na rezultate. Visok indeks tjelesne mase povezan s niskim razinama vitamina D Istraživači su otkrili da je povezanost između visokog indeksa tjelesne mase i niskih razina vitamina D svojstvena svim demografskim skupinama. Svako povećanje indeksa tjelesne mase za 10 posto uzrokovalo je padom razine vitamina D od 4,2 posto. „Pokazali smo da je povezanost između indeksa tjelesne mase i vitamina D prisutna kod svih bijelaca Sjeverne Amerike i Europe bez obzira na dob ili spol. Dokazali smo i da povećanje indeksa tjelesne mase dovodi do smanjenja vitamina D, a time i da pretilost predstavlja rizik za nedostatak vitamina D", izjavili su autori, podsjećajući kako je vitamin D nužan za zdravlje kostiju i sprečavanje bolesti poput raka, dijabetesa i visokog krvnog tlaka. Nedavno istraživanje provedeno na Sveučilištu u Kopenhagenu otkrilo je kako niske razine vitamina D mogu povećati rizik obolijevanja od srčanih bolesti i prerane smrti. „Naša studija ističe nužnost povećanja razine vitamina D kod pretilih osoba, kao i važnost praćenja i tretiranja nedostatka vitamina D kako bi se smanjili nepovoljni učinci pretilosti na zdravlje. Smanjenje pretilosti u populaciji trebalo bi dovesti i do smanjenja učestalosti nedostatka vitamina D", izjavili su autori istraživanja. Debljina i niske razine vitamina D povezane su s rizikom od dijabetesa Moguće je i da bi pretilost mogla utjecati, osim na smanjenje razine vitamina D, i na razvoj dijabetesa tipa II. Istraživači su otkrili da je rizik za razvoj inzulinske rezistencije veći kod osoba koje su i pretile i imaju nizak vitamin D, nego kod osoba kod kojih je samo jedan od tih dvaju čimbenika izražen. Shaum Kabadi i njegov tim sa Sveučilišta Dextrel otkrili su kako pretili ljudi s normalnom razinom vitamina D imaju čak 20 puta veći rizik za razvoj inzulinske rezistencije u usporedbi s ostatkom populacije. No, rizik kod pretilih ljudi s niskom razinom vitamina D veći je čak 32 puta.
