5 vitamin deficiencies your body is trying to tell you

It’s so common to have marks, bumps or blemishes on our body and just ignore them until they go away. But what if they don’t? What if your eyes, skin or hair is trying to tell you that you are lacking in a specific vitamin or mineral, which could be affecting your health and wellbeing? Speak to your doctor if you have any of these symptoms, and they can help you diagnose and treat any deficiencies. 1. Calcium deficiency Do you have weak or brittle nails, numbness in your extremities, or regular muscle cramps? Calcium deficiency could be a problem for you. It’s not just in dairy (though that is a great source) but also in seaweed, leafy greens, legumes and nuts. You can also find calcium-fortified products such as specific cereals, orange juice and soy milk. 2. Vitamin C deficiency Do you bruise more easily than you used to? Do you have cuts and wounds that seem to take a long time to heal? This could be a sign that you are low in vitamin C. And it’s not just from a lack of oranges. The best places to find this vitamin include strawberries, kiwi, broccoli and red capsicums. 3. Iron deficiency If you look unusually pale, have cold hands and feet, or a swollen tongue, you could be lacking in iron. As well as iron supplements, you can bulk up your iron intake with iron-rich foods such as red meat, fish and legumes. 4. Omega 3 deficiency Do you have bumps on the skin on your upper arms, dandruff, dry hair or dry eyes? You could be low in omega 3. Generally found in fish, seeds and nuts, leafy greens and eggs – it can also be ingested as a supplement from the chemist. 5. B12 deficiency B12 is readily available in meat, so this is a common deficiency in vegetarians and vegans. B12 is also less able to be absorbed from food as we get older. Signs of deficiency include skin irritation and dermatitis, lethargy and unusual weakness, pins and needles, and a smooth red tongue is also common (the little bumps disappear). You can get B12 in tablets or as an injection, but ideally you can get it from your food. Go for meat, leafy greens, mushrooms and nuts. Do you have any of these symptoms?

Vitamin C deficiency linked to cognitive impairment

A new study has found a link between poor brain function and how much Vitamin C older people have, and that a deficiency could have some serious effects on the brain. Cognitive impairment is common among older, hospitalised patients, and can result in poor memory and concentration, as well as finding decision-making difficult. The team from Flinders University in Adelaide tested the cognitive function and vitamin C level of 160 people over the age of 75 who were admitted to the university’s medical centre. From this, 91 patients were found to have cognitive impairment, and 42 of this group were found to have such low levels of vitamin C - below 11 micromoles per litre - they were at risk of developing scurvy. “Our findings showed that cognitive function scores were significantly lower among patients who were vitamin C deficient, with further analysis suggesting vitamin C deficiency was almost three times more likely to be associated with cognitive impairment after adjustment for other factors,” Associate Professor Yogesh Sharma, the study’s lead author, <a href="https://www.scimex.org/newsfeed/low-vitamin-c-linked-to-cognitive-impairment-in-older-australians" target="_blank" rel="noopener">said</a>. The researchers stressed that the two were associated, not that vitamin C deficiency causes cognitive impairment. They also noted that many of the symptoms of low vitamin C levels - including skin issues, bruising and bleeding - are common in this age group because of a number of conditions. “It may, therefore, be difficult to diagnose vitamin C deficiency solely on looking for these particular symptoms in older hospitalised patients,” Associate Professor Sharma said. “Given we know vitamin C deficiency is common among older hospitalised patients, medical professionals need to remain vigilant for this condition and confirm a patient’s vitamin C status in suspected cases.” With this link, the researchers said they will need to conduct more studies to confirm the link and determine whether replacing a patient’s vitamin C levels could help prevent or reverse cognitive impairment. The study was published in the journal <a href="https://doi.org/10.3390/antiox11030463" target="_blank" rel="noopener">Antibiotics</a>. Image: Getty Images

Five weird signs you’re iron-deficient

Though iron is one of the most important nutrients that is needed for many functions of the body, many of us don’t get enough of it. “Iron deficiency is the most common micronutrient deficiency worldwide,” said Dr Kelly Prichett, assistant professor of sports nutrition at Central Washington University. The World Health Organisation estimates that nearly half of the world’s 1.62 billion cases of anaemia - where an individual is lacking healthy red blood cells - can be traced back to an iron deficiency. When your body is low in iron, common signs include feeling tired, faint, or becoming breathless more easily. However, there are some more unusual signs that could indicate a dip in your iron levels, including these five. 1. Odd cravings for inedible items While the reasons why are still unknown, people with severe iron deficiencies often crave non-food items including dirt, clay, paint chips, cardboard, and cleaning supplies, according to the <a rel="noopener" href="https://www.nhlbi.nih.gov/health-topics/iron-deficiency-anemia" target="_blank">National Heart, Lung, and Blood Institute</a>. The condition, called pica, can be difficult to identify as many are ashamed to admit they have these unusual addictions. Pica typically occurs in young children or during pregnancy, but <a rel="noopener" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2850349/" target="_blank">case studies</a> have shown that older people can experience pica too. 2. Brittle or spoon-shaped nails Fingernails can be a surprisingly good indicator about your health, including when you’re experiencing iron problems. Along with weak and brittle nails, spoon nails can be a sign of iron deficiency. Also called koilonychia, spoon nails occur when the inside of your nail sinks in, leaving your fingernail shaped like a spoon. Since spoon nails can also be caused by exposure to petroleum-based solvents, trauma (such as a jammed finger), and other issues, doctors may need to perform a blood test for iron deficiency anaemia when there aren’t any other obvious causes. 3. Dry and cracked lips While many of us are familiar with chapped lips caused by harsh cold, a dry room, or licking your lips, people with low iron levels may be prone to a more specific kind of cracking that affects the corners of the mouth, called angular cheilitis. These cracks can make it difficult to eat, smile, or even shout. In a study of 82 people with the condition, 32 percent were found to have an iron deficiency. In those cases, creams or ointments won’t do the trick and the underlying iron deficiency must be addressed to stop the cracking from coming back. 4. An oddly swollen tongue Atrophic glossitis, also known as a swollen and tender tongue, is another less-than-obvious symptom of an iron deficiency. In a <a rel="noopener" href="https://www.jfma-online.com/article/S0929-6646(13)00406-3/pdf" target="_blank">2013 study</a> of people with iron deficiency anaemia, nearly 27 percent of the 75 participants were found to have atrophic glossitis, as well as dry mouth, a burning sensation, and other oral health issues. The swelling results in the tongue appearing smooth rather than bumpy, and can cause problems with chewing, swallowing, or talking. 5. A constant craving for ice Craving ice is a specific type of pica <a rel="noopener" href="https://www.ncbi.nlm.nih.gov/pubmed/15804997/" target="_blank">called pagophagia</a>, and is one of the most common symptoms of a severe iron deficiency. While the reasons behind this craving are unclear, some experts hypothesise that chewing ice may increase alertness in iron-deficient people - who often feel sluggish and tired - or that it may soothe swollen tongues. What to do about it If you experience several of the above symptoms, booking an appointment with your doctor may be the best next step. If you are feeling more tired than usual, struggle to catch your breath while walking up stairs or exercising, feel dizzy or often feel weak, you may need to check your iron levels with your doctor. In the meantime, eating iron-rich foods such as red meat, poultry, eggs, fish, nuts, or dark leafy green vegetables can help you take in some more iron.

7 signs you’re protein deficient

Whether you’re a vegetarian or an avid meat eater, protein is essential for your health. Composed of amino acids, protein is necessary for building and maintaining muscle mass, which is important whether you’re a gym junkie or a couch potato. If you’ve noticed any of the following signs, it may be time to pop more protein on your plate. <ol start="1"> <li>You’re craving food – if you find yourself desperate for a snack between breakfast, lunch and dinner, you may be eating too many carbs and sugars and not enough protein, which is essential for balancing blood sugar levels.</li> <li>You have pain in your muscles and joints – noticed you’re a bit weaker these days? Your muscles may be breaking down or joints releasing fluids to supplement the protein you’re not eating.</li> <li>You take ages to recover from injuries – protein is highly important to rebuild and mend damaged cells and tissue, so if you’re not eating enough, you may find your body takes longer to heal.</li> <li>You have weak hair, skin and nails – thinning hair, dry, cracked skin and weak, dented-looking nails are often the first signs of protein deficiency.</li> <li>You’re retaining lots of fluid – edema (fluid retention) can occur when you don’t eat enough protein, as it is responsible for preventing the accumulation of fluid in tissues, especially in the ankles and feet.</li> <li>You’re always sick – your immune cells are made from proteins, so if you’ve noticed you’re constantly sick, your immunity may have been compromised thanks to a lack of protein.</li> <li>Your mind is foggy – getting too many of your kilojoules from carbs can cause massive fluctuations in blood sugar, impeding your ability to focus. Protein helps restore the balance of blood sugar levels and removes that foggy feeling.</li> </ol> So, how much protein should you actually be eating? The recommended dietary requirement for men between 51 and 70 is 64 grams and 81 grams after the age of 70. For women, it’s 46 grams between the ages of 51 and 70 and 57 grams beyond 70. This means around 2 and a half to 3 serves of protein each day, which can come from lean meat, poultry and fish, dairy, seeds and nuts, beans and legumes, or soy products such as tofu. How do you incorporate enough protein into your diet? Tell us your tips in the comments below.

How to avoid omega-3 deficiency

You may be familiar with the term “omega-3s”, but what exactly are they and how can you ensure you’re meeting your nutritional requirements? Omega-3 expert Dr Bill Harris explains. More than 80 per cent of the world’s population is deficient in omega-3s, and many Australian are at risk of sub-optimal levels, due to poor dietary choices. Low levels of omega-3 may have a serious effect on your short and long-term health. But why are they so important for your health? What are omega-3s? Omega-3s are “fatty acids”. Fatty acids are the fundamental building blocks of life, like proteins and DNA, they are found in every cell in the body. Most fatty acids in the body are made from scratch by cells, but two classes cannot be made from scratch: the omega-6 and the omega-3 fatty acids – these must be obtained pre-formed from the diet. Typical western diets contain sufficient amounts of omega-6, but are now known to be low in the omega-3s. What are the different types of omega-3s? There are two most important omega-3 fatty acids are EPA – eicosapentaenoic acid and DHA - docosahexaenoic acid. These are found mainly in fish and other seafoods. A third omega-3, ALA – alpha-linolenic acid, is found in a range of plants foods, most predominantly in flax seeds, soy oil and walnuts. ALA must be converted in the body to EPA and DHA, but this is a very slow process. By including fish and seafoods in your diet two to three times a week, you'll ensure that your body is getting its required levels of the most important omega-3s. The more omega-3s you have in your cells, the better they function. Which foods can help boost my omega-3 levels? According the National Heart Foundation of Australia, Australians are recommended to include two to three servings of fish every week to obtain at least 250 to 500mg of marine-sourced (DHA+EPA) omega-3s. However, according to a recent survey, more than half (52 per cent) of Australians are not meeting this target. Your best choices are from “oily fish” such as salmon, mackerel, herring, trout, sardines, anchovies and tuna. ALA (short-chain) omega-3s are also present in some plant foods including chia seeds, walnuts and canoloa and soy oil. Can supplements help meet my nutritional omega-3 requirement? The most common way in Western countries to achieve the recommended intakes of 250 to 500 mg of EPA+DHA per day is to take an omega-3 supplement. There are many varieties, but they may be generally broken down into three categories by original source: fish, krill or algae. All three types can provide significant amounts of EPA+DHA, and they constitute the surest way to guarantee optimal intakes. Remember to always check with your healthcare practitioner to ensure that a supplement is right for you before adding to your diet. How do I know if I’m getting enough omega-3s? The only way to accurately know whether you are consuming enough omgea-3s is to test them. The <a href="http://www.omega3indexproject.com/" target="_blank">Omega-3 Index Test</a> is a simple, self-administered finger prick test, which requires one drop of blood dried on a small collection pad. This pad is sent to a laboratory for analysis, and a report is returned detailing your Index level. The target Omega-3 Index is eight per cent, above which is associated with the lowest risk for developing cardiovascular disease. An Omega-3 Index of four per cent or less is linked with a relatively high risk. Do you believe in taking supplements? Let us know in the comments below. Omega-3 Index testing is available through select practitioners and pharmacies.

The long-term problems with a B12 deficiency

Vitamin B12 deficiency can cause a range of symptoms such as tiredness, weakness, constipation, loss of appetite, weight loss and megaloblastic anaemia. Nerve problems, such as numbness and tingling in the hands and feet, can also occur. Other symptoms of vitamin B12 deficiency can include problems with balance, depression, confusion, dementia, memory and soreness of the mouth or tongue. Vitamin B12 deficiency can damage the nervous system even in people who don't have anaemia, so it is important to treat a deficiency as soon as possible. From a biochemical perspective vitamin B12 plays a critical role in keeping the body's nerve and blood cells healthy and helps make DNA, the genetic material in all cells. It is absorbed in a completely different way from most nutrients, in what is essentially a two-step process. Firstly, hydrochloric acid in the stomach separates vitamin B12 from the protein to which vitamin B12 is attached in food. After this, vitamin B12 combines with a protein made by the stomach called instrinsic factor and is absorbed by the body. Pernicious anaemia is a condition where the body cannot make intrinsic factor, subsequently these people have trouble absorbing vitamin B12 from all foods and even dietary supplements. You can also see how making good levels of stomach acid is essential to vitamin B12 status, and this is becoming a problem for more and more people. Vitamin B12 is found naturally in all animal foods and is added to some vegetable-based processed foods. Plant foods do not contain vitamin B12 unless they are fortified. If you believe your vitamin B12 deficient seek the advice of your GP, as often a regular B12 injection is required. You can also help to stimulate stomach acid production with apple cider vinegar before eating to see if this assists vitamin B12 levels.

Plant suffer from nutrient deficiencies too

Are your plants’ foliage suffering from discolouration or pigmentation? If you’ve ruled out pests or disease, your unhappy looking plants may be suffering from a nutrient deficiency. Plants need dozens of nutrients from the soil to thrive and a lack in any of them can result in the plant growing poorly. To help you narrow down the suspects these are the most common symptoms for nutrient deficiencies in plants. In most cases, a suitable fertiliser will help you combat the situation. Signs of nutrient deficiencies in plants Nitrogen Leaves are small and light green; lower leaves lighter than upper ones; not much leaf drop; weak stalks. Phosphorus Dark-green foliage; lower leaves sometimes yellow between veins; purplish colour on leaves or petioles. Potassium Lower leaves may be mottled; dead areas near tips and margins of leaves; yellowing at leaf margins continuing toward centre. Calcium Tip of the shoot dies; tips of young leaves die; tips of leaves are hooked-shaped. Magnesium Lower leaves are yellow between veins (veins remain green); leaf margins may curl up or down or leaves may pucker; leaves die in later stages. Sulphur Tip of the shoot stays alive; light green upper leaves; leaf veins lighter than surrounding areas. Iron Tip of the shoot stays alive; new upper leaves turn yellow between veins (large veins remain green); edges and tips of leaves may die. Manganese Tip of the shoot stays alive; new upper leaves have dead spots over surface; leaf may appear netted because of small veins remaining green. Boron Tip of the shoot dies; stems and petioles are brittle.
