Lack of dietary vitamin A increases the risk of skin infections and acne. Science has known for a long time that creams with synthetic vitamin A can be used against various skin problems, yet they do not know how vitamin A really works. Now, a study conducted by scientists from UT Southwestern Medical Center in Texas, USA, reveals the underlying mechanisms by identifying a bactericidal skin protein that requires vitamin A in order to work. But what kind of vitamin is vitamin A really? When does it work optimally? And is there in fact vitamin A in carrots?
We all know the importance of eating a healthy diet, exercising, getting sufficient sleep, and sunbathing with caution. Still, life is not always that simple, and even if we stick with the official guidelines for healthy living, it can often be challenging to get adequate amounts of the essential nutrients. Nonetheless, supplements are useful as compensation for these shortcomings. In fact, the use of such products can be compared with plant fertilizers that make plants look healthy, flourish and thrive.
Poor wound healing, a somewhat common and well-known problem, especially among hospital patients, is associated with huge health costs. Proper wound healing is contingent upon on the presence of different nutrients, and it appears that the ratio between omega-3 and omega-6fatty acids is particularly important. This was demonstrated in a new study of rats, where higher intake of omega-3 at the expense of omega-6 turned out to have the best effect on the formation of new blood vessels, increased collagen synthesis, and faster wound healing. In the study, which is published in Nutrients, the authors look closer at the fact that modern diets typically contain too much omega-6 and too little omega-3, and this contributes to problems such as cardiovascular disease, overweight, diabetes, and other lifestyle diseases.
According to a new study that is published in the British Journal of Nutrition, even minor zinc deficiencies may cause poor digestion, skin problems, and fatigue - and lead to numerous other health problems in the long run. You should therefore avoid zinc shortages, and people with poor diets, vegans, vegetarians, and older people should make sure to get enough zinc.
Having healthy-looking hair means a lot to most people. Hair that splits at the ends, hair loss, and other hair problems may be caused by stress, hormone changes, and numerous other factors. In this article, we will take a closer look at the diet and its impact on hair health, and we will look at available studies of protein, iron, zinc, selenium, silica, B vitamins, vitamin D and vitamin A. The fact is, we need plenty of these nutrients in a form that the body can absorb and utilize. On the other hand, getting too much can do more harm than good, according to an article in Dermatology Practical & Conceptual, in which the author has analyzed the available research.
Those with a higher dietary intake of vitamin A than what is officially recommended are 17 percent less likely to develop the second-most common skin cancer compared with those who get limited quantities of the nutrient, according to a study from Brown University in the USA. Beware that vitamin A is found in different forms in various foods and that one of these forms (retinol) can be overdosed.
“Before, I was losing hair but it stopped when I started taking selenium. Even my nails seem to be a lot stronger now,” says Maria Remenyi, a 70-year old lady who is amazed with the effect of the selenium tablets with zinc that she is taking.
New Year’s resolutions are often related to healthier living with better dietary choices, fewer stimulants, and more exercise. We want to stay as young and vital as possible with lots of energy. However, life is not always that simple, and nature often needs a helping hand. The following anti-ageing tips – including the essential beauty sleep – are based on a summary of articles that have all been published previously on this site.
More and more women take key nutrients that work from the inside to support smooth skin, strong nails, and healthy hair.
You probably spend a fortune already on expensive face creams and the like but did you know that a supplement combining two specific micronutrients is one of the best things you can take for your skin, hair, and nails? More and more women include selenium and zinc as part of their daily routine for beauty and appearance and find that it works surprisingly well.
Q10 is a coenzyme that is involved in cellular energy production and protection of our cells. There are numerous cosmetics with Q10 that are believed to delay skin ageing. However, only limited amounts of data have been available to prove the effect of Q10 on skin - until recently.
An important element in skincare and natural anti-ageing is to protect our cells against free radicals, which are aggressive oxygen compounds that we humans are exposed to. The free radical burden increases tremendously as a result of stress, too little sleep, ageing processes, smoking, inflammation, poisoning, medical drugs, and sunburns. Our only source of protection against free radicals is the presence of different antioxidants such as vitamins A, C, and E, selenium, zinc, and Q10, but we also need essential fatty acids. Optimal skincare requires that we get adequate quantities of the different nutrients, which are also an important element in our energy turnover. But what is skin ageing really? And why can we not simply stop it with anti-wrinkle creams, Botox, and plastic surgery? Also, which antioxidants and essential fatty acids are difficult to get in the right quantities?
Sulphur is essential for plants and animals. An adult contains around 175 grams of sulphur. The nutrient is found in the amino acids cysteine and methionine and is therefore also present in all the proteins and enzymes that contain these amino acids. Sulphur is a component of those enzymes that are responsible for ensuring that the hemoglobin in red blood cells is able to bind oxygen. Sulphur is also a component of the disulfide bonds that give strength to skin, hair, and nails. The reason why bird eggs have such a high sulphur content is that the nutrient is needed for the plumage of the developing bird. Sulphur is able to bind heavy metals and other toxins. Sulphur is chemically similar to selenium, but sulphur is not an antioxidant and has other functions in the body.
Vitamin B2 is water-soluble and because it does not get stored in the body we depend on regular intake of the nutrient. Vitamin B2 is also known as lactoflavin and is used as a yellow colouring agent/additive in various foods. When ingested in very large quantities vitamin B2 causes the urine to turn highly yellow. Vitamin B2 is destroyed by light, heating, and alcohol.
Photodynamic therapy is a kind of light therapy that is used to treat skin cancer, psoriasis, and other skin diseases. According to a review article published in Nutrients, vitamin D supplementation can improve the outcome of the treatment. In fact, vitamin D appears to have several positive effects on skin health. Taken in large doses, the vitamin can even repair skin damage caused by sunburns.
- here is a check list of typical signs and diseases
An estimated two billion people worldwide lack zinc. The essential trace element is involved in more than 1,000 different enzyme processes, besides being a powerful antioxidant that protects the body’s cells. Even minor zinc deficiencies can lead to impaired digestion, infections, skin problems, fatigue, impaired fertility, and DNA damage. Such deficiencies can eventually increase the risk of cancer and other diseases. People with unhealthy diets, vegetarians, vegans, older people, and pregnant and breastfeeding women are at particular risk of lacking zinc. Even if your diet provides sufficient amounts of zinc, different factors can affect the uptake and utilization of the nutrient, thereby increasing your body’s actual need.
– but will enrichment do the trick?
Even minor zinc deficiencies may cause poor digestion, infections, skin problems, and fatigue – and many other diseases may occur along the way. A new study shows that a diet with as little as four extra mg of zinc daily may strengthen cellular DNA and help protect the body. The four milligrams of zinc are about the same as populations with deficiency symptoms can get by eating zinc-enriched wheat and rice.
Zinc supplements have been given to patients with acne for years because of the anti-inflammatory properties of the nutrient. Still, it remains unclear whether zinc also helps treat other inflammatory skin diseases. Therefore, a group of scientists wanted to look closer at this and they discovered that zinc supplementation may be useful in the treatment of atopic dermatitis and diaper rash. Local treatment with zinc salve may also help.
Our skin is among the body’s organs that contains the most zinc, and the trace element is of vital importance to the formation and protection of skin cells. A zinc deficiency can therefore contribute to poor wound healing, sensitive skin, acne, eczema and other skin disorders, and hair loss, according to a new study that is published in the scientific journal Nutrients. Although clinical zinc deficiencies are rare in our part of the world, sub-clinical deficiencies are rather common. For instance, vegetarians, pregnant and breastfeeding women, and older people are particularly vulnerable. A large intake of sugar, calcium, and alcohol, the use of birth control pills and several types of medicine, plus certain diseases and other factors can also increase your risk of becoming zinc-deficient.
