Vitamin D Benefits – 9 awesome reasons
Vitamin D Benefits everyone’s health young and old. Vitamin D has multiple benefits and I have been a massive advocate of Vitamin D for many years due to my autoimmune family. Further strengthened when asked to write for the New Scientist on the tragic case of a murder trial.… So lets dive in to why you and your family need Vitamin D today….. It has been known for many years that Vitamin D is important for the following reasons: Vitamin D helps our body absorb calcium and phosphate, lowering the risk of tooth decay, cavities, and gum disease as well as ensuring our bones are flexible and strong. Vitamin D support the immune system which allows our body to fight off harmful bacteria and viruses. Vitamin D helps to strengthen muscles. Excitingly there is more to vitamin D than it was originally believed…..but before we get into that lets cover the basics…. Low levels of Vitamin D It is important to be aware that nearly half of the population have low blood levels of Vitamin D during winter months. This is especially low from January through to April/May when any summer sunshine stores you may have gained the previous summer are truly depleted. Those living in latitudes above ∼35° are significantly affected. In addition to depleted stores, many more people than ever have low levels of vitamin D due to changes in our lifestyles, less time outdoors, and the use of sunscreens. The elderly or those who are housebound are at very high risk all year round. Dark skinned people are also at risk. Further risk has been found in people who are obese, pregnant or a child due to either a lack of availability as Vitamin D is locked away in high fat stores or due to an increased need for development and growth in childhood and pregnancy. What are the Symptoms of a low vitamin D? The following symptoms can be common in those with Vitamin D deficiency: Fatigue Not sleeping well Bone pain or achiness Depression or feelings of sadness Hair loss Muscle weakness Loss of appetite Getting sick more easily What does vitamin D do for you? Tonnes!!! Interestingly Vitamin D is actually a steroid hormone but also known as a fat-soluble vitamin. This helps the body absorb and retain calcium and phosphorus; essential for building bone. How does Vitamin D work as a hormone? The body synthesizes Vitamin D after you have been exposed to the sun. It is then activated by the liver and kidneys. This activated form acts like a hormone to regulate calcium metabolism around the body. Vitamin D Benefits Cancer Exciting studies are now showing that vitamin D can reduce cancer cell growth, help control infections and reduce inflammation by stimulating the production of T-cells. These T cells help our bodies respond correctly to fight infections, including viruses, bacteria and fungus. These infections are responsible for various types of illnesses, including the common cold, and flu, Strep A and similar community-wide diseases. Vitamin D also aids in the repair and regeneration of cells, stimulate the death of cells that have been damaged by cancer, and lower the formation of blood vessels in tumours. Mood Vitamin D boosts your mood. Studies suggest that the decreased levels of Vitamin D3 may impact the levels of serotonin in the brain, this is a hormone that regulates the mood. By enjoining some safe sun each summer and, if in the Northern hemispheres taking a Vitamin D3 supplement in the winter, you could see a significant boost in your mood. Weight Loss Vitamin D can aid in weight loss. The chemical influence of Vitamin D is on serotonin, the “feel-good” hormone. This is known to assist appetite, sleep, mood, and stress levels. The connection to weight loss is believed that with sufficient levels of Vitamin D you are more likely to be motivated and have the energy to make the changes both mentally and physically to stay fit and healthy at a safe weight. Rheumatoid Arhtritis Vitamin D can lower the risk of rheumatoid arthritis. One of Vitamin D benefits is to help maintain the immune system and ensure that it is working correctly. A deficiency in Vitamin D could therefore increase the risk of developing rheumatoid arthritis as your immune system is more susceptible to attack. Type 2 Diabetes Vitamin D lowers the risk of type 2 diabetes. Not getting enough sunlight can reduce the secretion of insulin from the pancreas, which can create resistance to insulin and affect how the body responds to glucose. Sufficient vitamin D can help lower levels of cortisol. This is a stress hormone produced in the adrenal glands. Cortisol assists in the body’s response to stress. Prolonged high levels of cortisol can lead to increased abdominal fat. This is linked to several health conditions including diabetes type 2. Blood Pressure Vitamin D can help lower blood pressure. a large genetic study that involved more than 150,000 people revealed that low levels of Vitamin D can cause hypertension. In this study, those who had the highest levels of Vitamin D had lower blood pressure. It was found that a 10% increase in Vitamin D led to a 10 % reduction in high blood pressure. Heart Disease Vitamin D might reduce the risk of heart disease. Several studies have indicated that a deficiency in Vitamin D is a risk factor for developing high blood pressure, heart disease, congestive heart failure, peripheral arterial disease, strokes, and heart attack. What causes vitamin D to drop other than sunshine? Vitamin D deficiency as mention is most commonly caused by a lack of exposure to sunlight. However some medical disorders can also cause Vitamin D deficiency. The most common causes after sunlight is a poor diet, medications and certain disorders. Cystic fibrosis, Crohn’s disease and Coeliac disease are conditions that can prevent your intestines from adequately absorbing enough vitamin D through diet and even supplements, especially if
It’s Been a While – Vitamin D
Hi, well what a year it has been. Work has pushed my boundaries further than ever imagined, the kids school and social demands continue unabated and we are now heading to another episode of over indulgence! Looking back, we have had a disappointing amount of summer sunshine, not good for Vitamin D stores or for the fun picnics we so love. We did have a fab trip which was a special treat and it certainly made up for our poor weather; a royal Caribbean cruise! Wow, as a Dietitian it was a sight to behold. The food choices were superb from both ends of the spectrum! The holiday guests, some whom had definitely been there before, could eat 24/7 and some did. Initially I found it all a little overwhelming and off-putting, but once I realised that the majority were not all gluttons we had a holiday of a lifetime! Vitamin D As we come into the winter it is important to be aware that nearly half of the British population have low blood levels of Vitamin D during the winter and spring months. This has come from changes in our lifestyles, less time outdoors, and increased use of sunscreens. If you are Obese, pregnant or a child you are at further risk due to either lack of availability with high fat stores or due to an increased need for development and growth. Why Worry? Rickets, a bone disease from the Victorian times, that had diminished, is now increasing significantly, leading to bow legs and short height, if prolonged it results in adults as osteomalacia. Recent Scientific literature has linked this important vitamin to not alone bone health; rickets, oesteoporosis (brittle bones) but also low levels of vitamin D are linked to increased risk of heart disease, high blood pressure, breast and colon cancer, impaired immunity, type I diabetes, arthritis and multiple sclerosis. What Can You Do? Careful exposure to the sun in the summer months (pale skin achieves sufficient amounts 10 times faster than darker skin) is considered essential but maybe not enough. Food Sources: Salmon- wild and baked is an excellent source. Baking has no effect on Vitamin D content whereas frying reduces it by 50%! Sun dried Shitake mushrooms is also highly concentrated, sardines canned, mackerel and tuna canned. Some breakfast cereals are higher than others so check the labels. Some manufacturers are aware of this deficiency worry and products like breads are being fortified, polyunsaturated margarine are also fortified. Until further fortification is widespread supplements maybe necessary. Make sure you are getting enough from your diet and sunshine and then top up over the winter months.
