Skin

Moisturized, radiant, with even color, firm and without breakouts. That should be our skin. However, not everyone can boast of a flawless complexion. Many factors affect the condition of the skin, some of them are also associated with diet. Do you know what products positively affect the condition of the skin and which do not serve it? We invite you to read!

Leather – construction and properties
Seemingly delicate and extremely sensitive, it protects the rest of the body against the harmful effects of mechanical, chemical and biological factors. Its main task is to maintain the balance between the external and internal environment. It is also a key element of the immune system, it creates the first barrier for microorganisms. Thanks to the secretory capabilities, it participates in the removal of many substances from the body and regulates the body temperature. The skin in the thickest place on the body is only 5 mm thick and is made up of three layers. These layers are the epidermis, dermis and subcutaneous tissue. The stratum corneum of the epidermis contains in its structure lipids and keratinocytes, which are responsible for water retention and proper hydration of the skin. The most important lipids present in the epidermis are ceramides and phospholipids. In addition to the regulation of hydration, they are responsible for barrier capacity, maintaining proper pH, proper skin breathing and metabolite exchange. The dermis is responsible for maintaining the immunological barrier, and due to the presence of collagen fibers, it is responsible for firmness and proper hydration.

The skin layers also include sebaceous and sweat glands, receptors sensitive both to cold and heat, nerve endings and capillary blood vessels. Their proper functioning and cooperation is a prerequisite for a good skin condition and, consequently, for a nice look. Properly moisturized and nourished skin fulfills all its functions even in extreme conditions.

Problems arise when the skin does not receive all the necessary ingredients and compounds. Then it begins to signal irregularities by the appearance of stains, discolorations, and breakouts on its surface. Other symptoms to which attention must be paid include redness and dryness of the skin.

Factors negatively affecting the appearance and condition of the skin
The skin is affected by both external and internal factors. Belong to them
– nutrition,
– addictions (alcohol abuse, smoking),
– UV radiation (no use of sunblock, frequent visits to the tanning bed),
– detergents,
– hormonal conditions,
– genetic predisposition,
– ceramide metabolism disorders,
stress,
– diseases and inflammation.

To be able to enjoy smooth skin with even color, it is necessary to comprehensively care for your body and if possible minimize the harmful effects of these factors, which are also responsible for the aging process and the loss of some skin properties.

Food ingredients favorably affecting the condition of the skin:

Water

Water is the main component of the human body. An adequate supply of water during the day has a positive effect on the functioning of the body. Water provides, among others maintenance of the correct thermoregulation process, maintenance of water-electrolyte balance and acid-base balance. Also, it is very important in maintaining the proper condition of the skin. It has been proven that the consumption of the right amount of water maintains proper skin tension. It also contributes to the increase of blood flow in the capillary vessels, which is associated with maintaining an adequate blood supply, elasticity, and firmness of the skin. Water shortages in the body affect the increase of dryness of the skin.

Vitamins
Particular attention should be paid to vitamins known for their strong antioxidant activity. This is about vitamins A, C and E. They have a significant impact on the proper functioning of the skin and its regeneration.

Vitamin A not only affects the color and nice appearance of the skin, additionally eliminates sun discoloration, stimulates the production of collagen and elastin in the proper skin layer, regulates sebaceous glands, accelerates the process of healing the skin and mucous membranes, and is an important part of acne and psoriasis treatment. Vitamin A is present in animal products and red, yellow and green vegetables and fruits (in the form of beta-carotene).
Vitamin A Drops
Vitamin E protects the skin against free radicals, accelerates its regeneration, slows down the aging process and prevents skin keratosis. Its source is vegetable oils, fatty fish and nuts.

Vitamin C with Quali-C 1000mg

Vitamin C also shows a similar effect. As a powerful antioxidant, it eliminates the effects of the presence of free radicals. The body is supplied by eating vegetables and fruits. However, it should be remembered that it is very sensitive to exposure to oxygen, temperature, and light, therefore the most vitamin C will have unprocessed vegetables and fruits collected in the season of their natural maturation.

Best Tocotrienols 50mg

The research carried out in 2000 and 2003 by the National Food and Agriculture Organization suggested that the intake of vitamins among Poles does not coincide with the recommended norms. Deficiencies of B group vitamins and vitamin C are very common.

In turn, there is excessive consumption of vitamins A and E, especially in women, which may be the result of making preparations to improve the condition of hair, skin, and nails.

Mineral ingredients
In addition to vitamins, proper supply of macro- and micronutrients is very important. Calcium, potassium, iron, selenium, copper, zinc, iodine and silicon affect the proper skin condition and maintain its properties. These mineral ingredients allow you to maintain skin elasticity, prevent drying and scaling, alleviate the symptoms of acne and accelerate its treatment and have a positive effect on the processes of wound healing and skin damage. To maintain the proper levels of individual elements in the body, the diet should include whole grains, lean meat, fish, eggs, legume seeds as well as nuts and seeds.

Zinc Glycinate 30mg

Essential unsaturated fatty acids
As the name suggests, it should necessarily appear in our diet. They have an extremely wide spectrum of action and have a positive effect on the entire body. Today, however, we are interested in their impact on the skin. In the dermis layer, some ceramides and phospholipids require linoleic and alpha-linolenic acids, which are obtained by the body as a result of transformations of essential fatty acids, namely omega-3 EPA and DHA.

EPA-DHA Balance
 
What effect do the fatty acids have on the skin? They prevent and alleviate inflammation and irritation, reduce dry skin occurring at hand and foot keratoderma, ichthyosis, psoriasis, atopic dermatitis or acne, maintain proper skin hydration and regulate the process of keratinization of the epidermis. To provide the body with adequate amounts of omega-3 fatty acids, the diet should contain nuts, linseed, and linseed oil, pumpkin seeds, and fatty sea fish.

Polyphenols
These compounds are also strong antioxidants and are responsible for maintaining the close skin barrier and its condition. Neutralizing the action of free radicals, they slow down the aging process and condition the proper functioning of the skin. Polyphenols additionally protect the skin against the occurrence of discoloration. The source of polyphenols in the diet are tea (green and black) and fruits and vegetables of dark and intense color (peppers, beets, Aronia, cherries, blackcurrant, without). The darker the color, the higher the content of polyphenolic compounds.

Food products adversely affecting the condition of the skin
To visibly improve the condition of the skin it is necessary to exclude highly processed products from the diet, with the addition of preservatives, artificial colors and flavor enhancers. Consuming such foods in large quantities may result in the intensification or occurrence of acne lesions, allergies, allergies, urticaria, and even inflammation.

The recommendations of the NGOs inform about the health benefits of limiting or even eliminating the consumption of simple sugars. Normalizing blood glucose in this way supports and facilitates weight loss and general health. Another benefit of reducing the number of simple sugars in the diet is improving the condition of the skin. This is due to the presence of different hormones in the skin layers. Both excess and hormone deficiency disturbs the work of receptors, which leads to dryness and flaking of the skin, excessive secretion of sebum, the appearance of breakouts and other skin changes.

Plants improving the condition of the skin
Not only food has a positive effect on the appearance and overall condition of the skin. To improve its condition, it is also worth reaching for medicinal plants. They are often more effective and safer than the cosmetics for care that are popular in drugstores.

Medicinal plants affecting the skin Spirulina
– aloe vera,
– mountain arnica,
– Plantain
– regular onion,
– tea tree,
– St John’s wort,
– three-colored violet,
– purple coneflower,
– red oak,
– stopper rhizome,
– white jasmine,
– lemon balm,
– marigold,
– melilot,
– witch hazel,
– Walnut,
– oats,
– poplar buds,
– chamomile,
– horsetail,
– horse’s thigh,
– two-year evening primrose,
– comfrey.

The aforementioned medicinal plants are mostly applied locally to the skin as compresses or compresses. They can also be used as infusions, baths, tonics or oils. Some of them (oats, nuts, chamomile, onion, etc.) can be included in the daily menu if possible. The substances contained in the discussed plants have anti-inflammatory, antiseptic, astringent, soothing properties and also accelerate wound healing and regeneration. Before using medicinal plants, we advise you to go to the attending physician or a dermatologist to consult safety and possible interactions with medications and to rule out possible allergic reactions.

Non-nutritional factors affecting the condition of the skin
There is a close relationship between the level of stress and the condition of the skin. Stress, both caused by physical and mental factors, affects the functioning of the immune system. The neurotransmitters secreted as a result of this have a significant impact on the occurrence of dermatological diseases, especially those with an inflammatory basis. It is believed that diseases such as atopic dermatitis, psoriasis, alopecia areata, urticaria, acne, lichen planus or albinism can develop due to emotional factors affecting our psyche and not cope with severe, chronic stress. Stressful conditions not only contribute to the occurrence of dermatoses but also exacerbate the course of those already occurring.

The skin is located in sex hormone receptors. Most of them are around the face. The occurrence of abnormalities in the secretion of hormones may initially be manifested by dryness and redness of the skin. Over time, there is visible loss of skin firmness and acceleration of aging processes manifested by the occurrence of wrinkles and slower regeneration (healing of wounds and skin damage). According to the authors of the study, also the high intake of simple sugars that affect the problems associated with the secretion and sensitivity of cells to insulin leads to dysregulation of the entire hormonal balance of the body.

Resveratrol 50mg

In scientific research it has been proven that tobacco smoke, and specifically the compounds contained in it, cause problems with wound healing, acceleration of skin aging, psoriasis Vulgaris, pustular pustules of hands and feet, skin and mucous membrane tumors, multiple axillary embryoids, warts and genital organs, and even Buerger’s disease. It is also suspected that smoking may have a significant impact on the development of acne, hand eczema, and malignant melanoma. Substances contained in tobacco smoke can cause a significant exacerbation of the course of these diseases. Such a strongly negative effect of cigarette smoking on the condition of the skin is associated with a wide range of activities, including nicotine stimulates the secretion of acetylcholine affecting the secretion of sweat, sebum, microcirculation, and angiogenesis. At the same time, it can also modulate the proliferation, migration, and differentiation of keratinocytes. Another effect of smoking is a significant decrease in the level of antioxidative vitamins in the body, especially A, C and E, which protect the skin against free radicals and condition its proper regeneration.

The style and way of feeding people with skin problems should be based on the recommendations of the Institute of Food and Nutrition. Specifically, it’s here for a varied diet based on unprocessed products and with the largest share of fresh vegetables and fruits. It may be helpful to stop smoking and reduce stress in helping to treat or relieve symptoms. It is good to do a hormone level test that also affects the appearance and condition of the skin.

Allergens in food

People are increasingly following dietetic novelties. Currently, the so-called allergen fashion. Many well-known people from the fitness industry are in favor of excluding allergens from the diet. Among other things, it is said that the consumption of gluten brings with it the same negative effects, and dairy products are pure evil, so it is best to eliminate these products from the diet. However, this is not entirely correct. Of course, some people are allergic to certain products or ingredients. Then, the use of a diet with the exclusion of an allergen is justified. But is it worth blindly following the fashion and excluding from the diet products that are widely regarded as allergens? Is it better to reach for the products we want and not to think about the health consequences?

Allergy and allergens
Allergy involves the occurrence of an immune reaction that is associated with the formation of antibodies that, when bound to the antigen, leading to the release of various substances that are so-called. mediators of inflammation. Symptoms of allergies are very diverse. There may be urticaria, angioneurotic edema, allergic stomatitis, gastro-oesophageal reflux, anaphylactic shock, allergic rhinitis, asthma, otitis media, chronic allergic reaction of the stomach and duodenum, and diarrhea. Of course, these symptoms relate only to people who are allergic to a given nutrient. Side effects after consumption of a given product should not occur in healthy people.

In Poland there is a list of products that can cause allergic reactions or intolerance reactions, these are
– cereals containing gluten, such as wheat, rye, barley, oats, spelled and their derived products;
– crustaceans and products thereof;
– eggs and derived products;
– fish and products derived thereof;
– groundnuts (peanuts) and derived products;
– soya and products thereof;
– milk and derived products;
– nuts, such as almonds, pistachios, walnuts, hazelnuts, cashews, pecans, brazil nuts, macadamia nuts and products thereof;
– celery and derived products;
– mustard and derived products;
– Sesame seeds and derived products;
– sulfur dioxide and sulfites in concentrations above 10 mg/kg or 10 ml / l based on the total SO2 content in the product;
– lupins and derived products;
– mollusks and derived products.

Types of allergic reactions
In adults, there are three types of reactions that can occur after ingestion of an allergen, they are

– immediate allergic reaction – clinical symptoms appear here immediately after ingestion of the allergen, maximum after 10 minutes. It can be both light urticaria and a serious anaphylactic shock;

– an allergic reaction of the cytotoxic type – the reaction develops in various tissues and organs. Antibodies are directed against antigens present on the body’s cells. There is a destruction of cells and activation of other mechanisms of the immune system;

– allergic-type of immune complexes – clinical symptoms may occur even after a few hours up to several days after ingestion of the allergen.

If you are diagnosed with an allergy to a particular nutrient, it is necessary to exclude it from the diet to avoid adverse symptoms. Of course, the allergy may manifest itself harmlessly, eg urticaria or skin irritation, but if the allergen is not eliminated from our diet despite the diagnosis of allergies, it is also possible to have more serious symptoms such as anaphylactic shock.

Elimination diet
The elimination diet is not only a way to detect which food component triggers an allergic reaction. It is also a way of treatment. When we find out which ingredient is allergic to our body, it is necessary to exclude it from the diet. After some time after the allergen has been discontinued, you can try to re-add it to meals, but remember to do it gradually and give it in small doses. If an allergic reaction does not occur, you can gradually increase the dose of the allergen. However, we do not need to re-enter the allergenic substance if the previous allergic reaction was quite strong.

In the elimination diet, attention should be paid to any shortages that may result from the complete elimination of a given product from the diet. Then, to avoid deficiencies, especially vitamins and minerals, it is worth reaching for products that are also a good source of this ingredient. The best solution will be to consult a dietitian.

Of course, the fact that we do not have any allergic reaction after eating food does not mean that we should not pay any attention to what we eat. It is particularly important to maintain common sense. If, for example, after eating eggs we feel flatulence and discomfort in the abdomen, it is worth reducing them in the diet. The most important is the pleasure of eating. However, if we decide to eliminate one of the products from the diet, it is worth paying attention to whether it will not cause deficiencies of vitamins and minerals. If this option arises, you may want to consider supplementing or increasing the supply of a given substance from other food products.

How to determine if you are dealing with allergies
Recently, avoiding products that are considered allergenic has become very popular. Too many people exclude certain products from their diet without a logical explanation. They follow the so-called allergen fashion. People from extremes go to extremes.

Histamine Block

 

However, before we completely decide to exclude a given allergen from your diet, it’s worth knowing your body. To do this, start a healthy, well-balanced diet. It should contain all necessary macronutrients, vitamins, and minerals. If you are a newbie in the field of dietetics, you should take advantage of the pyramid of healthy nutrition and take physical activity. If you do not feel any negative symptoms when using such a diet, there are no grounds to exclude a given product from our daily menu.

However, if you observe disturbing symptoms such as rash, hives, runny nose, stomach pains, nausea, etc., it is worth considering introducing an elimination diet. For this purpose, it is best to go to a specialist who will diagnose the problem and help us balance the diet accordingly.

Allergen recognition is often based on trial and error. In the beginning, you should exclude from the diet the most allergenic products, such as milk, eggs or grains containing gluten. Such a diet should be carried out for several weeks until the symptoms disappear completely. You can then re-enter the product you removed from the diet, such as milk. If the symptoms return, it means that the product that causes us allergic reactions is milk. Once we know what product is allergy-giving to us, it is necessary to completely exclude it from the diet to minimize the risk of adverse symptoms.

Therefore, there are no medically valid arguments for which healthy, properly nourishing people would exclude from the diet any products commonly considered as allergenic. The start of the elimination diet is recommended only to people who have an adverse allergic reaction to a given product.

Stretch marks

The skin is a delicate “matter covering our body. Therefore, it should not be too surprising that in the case of local loss of integrity – weakening of the structural core layer – we use the word stretch, which is associated with a stocking in which “eyes flew.

The scientific name-striae distensae-was introduced by Roderer in 1773, who first described the phenomenon of stretch marks. It was not until 1867, however, Koestner explained them from the histological point of view, highlighting the atrophy of the basic substance and fibrous component, which he gave the name striae atrphicae. 

Appearance and occurrence 

Striae appear as linear, parallel strands separated by healthy skin. Their appearance is usually asymptomatic, but it can be combined with a gentle sensation of pruritus, less burning, pain. 

The color of these highlights depends on the evolutionary phase. At the beginning, when the inflammatory component, pseudo-hypertrophic, prevails, the stretch marks are red, red or red-blue. in the scarring phase they are thinner, more even, sunken in relation to the surrounding skin and become whitish, sometimes with a pearly shade. Stretch marks are usually bilateral, i.e. appear on both sides of the body, in every area of ​​the body except for face, hands and feet. On the belly they can have a radiant or fan-shaped look, on the hips transverse, on the breast radial from the nipple, and in the lumbosacral region are horizontal. In women, this disorder occurs twice as often as in men, it can occur at any age, although most often during puberty and pregnancy. In the first case, it concerns 35% of young people. The most frequent spots of stretch marks are in the case of girls’ hips, thighs and breasts, in boys the cross-lumbar region. 

Pathogenesis 

Medical literature in relation to the histological structure of stretch marks is admittedly ambiguous, but the most characteristic features can be distinguished. These are the diminutive epidermis, which lost its papillary drawing, and the dermis – also thinner, with changes primarily in the fibrin component. Collagen fibers are joined in groups arranged parallel to the surface of the skin, while elastic fibers at the sub-median level are atrophied, and in other areas are few and very delicate. The cellular and vascular component is small, and the hair and seborrhea attachments are practically absent. Stretch marks, being widespread pathology, are still not well known in terms of its pathogenesis. Most researchers accept the two theories of their emergence in the environment and mechanics. According to the first, the formation of stretch marks is associated with excessive secretion of glucocorticoids. According to the second – with rapid elongation and shortening (traumatism, strong and repetitive muscle contractions, such as in sports), which cause the vascular and fiber components of the skin to be drawn, leading to local ischemia and discontinuation of collagen fibers. In fact, both mechanisms play a fundamental role in the formation of stretch marks, and they benefit from individual genetic predisposition. 

Striae once created, remain indefinitely. Sometimes they may be partially repressed, probably as a result of the genetically determined ability of the body to respond to mechanical injuries. 

Early prevention

Currently, there is no medical therapy, which is able to cause them to disappear. For this reason, prevention is so important and early, because stretch marks arise at a very young age. 

Therefore, it is important to control body weight, which is not only about obesity as such, but also to limit excessive increases in body weight during pregnancy and to avoid overly rapid and rapid dietary therapies. To maintain the best condition of the skin, proper nutrition is essential. You must remember to provide proteins, lipids, carbohydrates and vitamins (A, E, PP, B5) in an amount depending on the physiological state (pregnancy, puberty). 

Physical exercises must be progressive; avoid long-lasting and strong muscle cramps. The combination of moderate sports activity and massage improves vascular and lymphatic microcirculation and may be useful for toning the tissues and preventing the formation of these aesthetic defects, especially during pregnancy. 

Typically cosmetological prevention is based on the local use of creams, gels, oils and plant-based preparations, elastin, collagen, biostimoline, vitamins, placental preparations, acetazolamides, alpha-hydroxy acids, etc. Precursors are also present in local preparations. Collagen, such as proline linoleate, hydroxyproline complex and others.
