Vitamin D Benefits – 9 awesome reasons

Weight loss happy lady

  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

Essential Nutrition for Recovery after Surgery (Part 1)

In the first of a two-part series, Director and Principal Dietitian Gillian Killiner, discusses the relationship between good nutrition and surgery and how this can help your recovery process. Are you waiting for an operation? More and more people are spending months on waiting lists for minor and major surgery. Waiting when you are in pain or unable to function can have a devastating effect on your day to day abilities. If severe, your ailment can affect your job and income. These and many other issues related to surgery can negatively impact on your mood, your ability to eat, sleep, movement, your mental health and general well-being. Surgery is a deliberate, skillful injury to your body which following, may take you several weeks or months to heal. Infections and blood loss are two possible complications that you will want to avoid. While you are waiting for your procedure you can do your part to make sure you heal well without problems. You can do this by choosing the most nutritious diet well in advance of your hospital admission. Surgery is a big event. It makes sense to give yourself extra nutrition, so you can replace any blood loss and protect your immune system against infection. These same nutritional elements will repair your skin, nerves, blood vessels, muscle and bone and get you back on your feet again. What do vitamins and minerals do for you? The following are a snapshot of the major ones to assist your recovery: Vitamin B12 Vitamin B12 is the largest and most complex of all the vitamins. You need vitamin B12 so your body can create energy from your dietary fats and proteins. B12 is needed for you to make haemoglobin. It even helps your memory, mood and brain function. Vitamin B12 deficiency affects about 15 percent of people over the age of 60. There are several reasons people are low in B12: age, alcohol, bacteria infection and certain drugs. B12 rich foods include: beef, shellfish, cottage cheese, chicken, egg and nutritional yeast. Folate Folate plays a vital role in the work and growth of all your body cells. Not having enough folate causes problems in the cells. Some of your immune system white blood cells will be affected. If you do not take in enough folate you will experience fatigue, weakness, and shortness of breath. Never take a folate supplement without making sure you have enough Vitamin B12. Folate rich foods include: spinach, kale, Brussels sprouts, cabbage, broccoli, beans and legumes (e.g. peas, blackeye beans), yeast and beef extracts, oranges and orange juice, whole grain foods, poultry, pork, shellfish and liver. Vitamin B6 Vitamin B6 is needed for the proper function of about 100 essential chemical reactions in the human body. People who are low in vitamin B6 have impaired immune function. This is especially true for the elderly. Sleep, pain, mood, memory, and clear thinking are also affected by a shortage of Vitamin B6. The stress of hospitalisation for surgery causes many people to lose sleep. Increased pain and mood changes are also common. You may find your appetite is changed when you are in the hospital. Vitamin B6 is important at this time. B6 rich foods include: turkey, beef, pistachios, tuna, avocado, chicken, sunflower seeds, sesame seeds. Vitamin B1 (thiamine or thiamin) Vitamin B1 plays a critical role in making energy from food. It is needed for your heart, digestive system, and nervous system. Your muscles especially need vitamin B1 to work properly. Alcoholism is linked with a low intake of thiamine and other nutrients. If you drink large amounts of tea and coffee (even decaf), you may end up with not enough thiamine. This is because of the action of certain enzymes in these drinks. Vitamin B1 foods include: nutritional yeast, seaweed, sunflower seeds, blackbeans, lentils, white beans, asparagus, sprouts. Vitamin B2 (riboflavin) Riboflavin or Vitamin B2 is essential for changing the carbohydrates, fats, and proteins in your food into energy in your cells. It also helps manage drugs and toxins in your liver. If you do not have enough riboflavin you may not be able to absorb the iron, you need to make haemoglobin in your red blood cells. Riboflavin improves your ability to prevent or recover from iron-deficiency anaemia. Food rich in B2 include: liver, seaweed, feta, almonds, tempeh, mackerel, eggs, tahini. Vitamin B5 Pantothenic acid is essential to all forms of life. It is another of the vitamins you need in order to create energy from your food. Vitamin B5 will speed up wound healing. It can also increase the strength of scar tissue. Vitamin B5 rich foods include: beef liver, avocado, sunflower seeds, duck, portobella mushrooms, eggs, salmon, lentils, plain yoghurt, broccoli. Vitamin B3 (niacin) Vitamin B3 is also called nicotinamide or nicotinic acid. It is required for the proper function of more than 50 enzymes. Without it, your body would not be able to release energy or make fats from carbohydrates. It’s important for insulin-dependent diabetes. Vitamin B3 rich foods include: beef liver, chicken, tuna, lamb, salmon, sardines, turkey, white mushrooms. Biotin Biotin is one of the B-complex vitamins. It is needed for four important enzyme reactions in your body allowing cell growth and immune system protection against bacterial and fungal infections. If you do not have enough biotin it can lead to depression, a sense of tiredness, and weakness. You may also notice a rash on your face and numbness and tingling of your hands or feet. If you have brittle fingernails or notice increased hair loss, you may be low in biotin. Biotin rich foods include: liver, eggs, yeast, salmon, cheese, avocado, raspberries, cauliflower. Vitamin C Vitamin C is a water-soluble vitamin. Unlike most mammals, humans do not have the ability to make their own vitamin C. You have to get the vitamin C you need through what you eat and in supplements. (These are not all the same and can do more harm than good.) Vitamin C is a powerful antioxidant required to
