Foods for Beautiful Skin: What Supports the Skin from Within

The skin is our largest organ and a true mirror of our lifestyle. Alongside care from outside, nutrition also plays a role in how well the skin is supplied with the nutrients it needs for its normal function. Through the right choice of foods, a fair amount can be supported from within. In this guide you will learn which foods provide especially skin-friendly nutrients, how high the requirement is and how to improve absorption.

Why the right nutrients are important for the skin

For the skin there are several approved claims in the European Union. Thus: Vitamin C contributes to normal collagen formation for the normal function of the skin. In addition, biotin contributes to the maintenance of normal skin, niacin contributes to the maintenance of normal skin and riboflavin contributes to the maintenance of normal skin. Also, vitamin A contributes to the maintenance of normal skin and zinc contributes to the maintenance of normal skin.

Another important aspect is the protection of the cells. Vitamin C contributes to the protection of cells from oxidative stress and vitamin E contributes to the protection of cells from oxidative stress. This variety shows that no single ingredient is decisive, but rather the interplay of many nutrients from a varied diet. That is why individual so-called superfoods do less for the skin than is often promised. Much more effective is a consistently balanced diet that continuously provides the skin with all the building blocks it needs.

The best foods for the skin

Skin-friendly nutrients are found in vegetables, fruit, nuts, seeds, fish, eggs and pulses. The following figures refer to 100 grams each and serve as orientation.

• Bell pepper, red: very high vitamin C content (about 140 mg)
• Citrus fruits and berries: good vitamin C sources
• Carrots and sweet potatoes: rich in beta-carotene (precursor of vitamin A)
• Kale and spinach: provide vitamin C, beta-carotene and folate
• Almonds and hazelnuts: good vitamin E sources (about 26 mg and 15 mg respectively)
• Sunflower seeds: rich in vitamin E
• Eggs: provide biotin, riboflavin and vitamin A
• Salmon and herring: source of omega-3 fatty acids
• Oat flakes and whole grains: provide biotin, niacin and zinc
• Pumpkin seeds and beef: good zinc sources
• Pulses: provide zinc, niacin and plant protein
• Avocado: provides vitamin E and unsaturated fatty acids

Anyone who eats colourful vegetables and fruit daily, plus nuts, whole grains and regularly fish or egg, supplies the skin with a broad spectrum of nutrients. It is interesting that many skin-friendly nutrients fulfil several tasks at once. Vitamin C is not only involved in collagen formation but also contributes to the protection of cells from oxidative stress. Zinc plays a role both for the skin and for the immune system. These multiple functions are a good reason to rely on a broad nutrient supply rather than on individual isolated substances.

The colour of the foods also gives a practical clue. Strongly coloured vegetables and fruit often contain especially many secondary plant compounds and vitamins. Red bell pepper, orange carrots, dark berries and deep green leafy vegetables are therefore good reference points for a skin-conscious selection. Anyone who pays attention to variety and colour when shopping almost automatically ends up with a nutrient-rich composition.

How high is the daily requirement?

The EU reference values for labelling give an orientation: vitamin C 80 milligrams, vitamin E 12 milligrams, zinc 10 milligrams, niacin 16 milligrams, riboflavin 1.4 milligrams, biotin 50 micrograms and vitamin A 800 micrograms per day. These amounts are readily achievable with a balanced diet.

Biotin occurs in so many foods that a deficiency with a normal diet is rare. Niacin and riboflavin are also well covered through whole grains, meat, dairy products and pulses. Beta-carotene is converted by the body into vitamin A as needed, so that an oversupply through vegetables practically does not occur.

In practice these values are effortlessly achievable if the diet is varied. A red bell pepper already clearly covers the vitamin C reference value, a handful of almonds provides a large part of the vitamin E requirement, and an egg brings along biotin and riboflavin. Zinc comes from whole grains, pulses, seeds and meat. Anyone who spreads these foods over the week hardly needs to worry about individual nutrients. The variety ensures that the intake balances itself out and no gaps arise.

How you support absorption

Some skin-friendly nutrients are fat-soluble, including beta-carotene, vitamin A and vitamin E. They are absorbed better if you combine them with a small amount of fat. A splash of oil over the salad, avocado with the vegetables or a handful of nuts improve the utilisation significantly.

Vitamin C, by contrast, is water-soluble and heat-sensitive. Therefore you should prepare vitamin-C-rich vegetables and fruit as fresh and gently as possible in order to preserve the content. A combination of raw and lightly cooked vegetables covers both aspects. Sufficient drinking also supports the skin, since it depends on a good fluid supply.

An additional advantage of a nutrient-rich diet lies in the healthy fats. Unsaturated fatty acids from nuts, seeds, avocado and fatty fish are not only important for the absorption of fat-soluble vitamins but generally belong to a balanced diet. They also make it easier to utilise skin-friendly fat-soluble nutrients at all. Anyone who eats very low in fat therefore gives away part of the benefit that vitamin-rich vegetables offer. A moderate amount of high-quality fats with every meal is therefore a simple and effective lever.

Eating skin-friendly in everyday life

A skin-friendly diet corresponds in large parts to what is generally considered balanced: plenty of vegetables and fruit, high-quality fats, sufficient protein and whole grain products instead of heavily processed foods. The advantage of a colourful selection lies in the fact that it automatically provides a broad spectrum of vitamins, minerals and secondary plant compounds.

Alongside nutrition, other factors also play a role for the skin, such as sufficient sleep, a moderate approach to sun and suitable care from outside. Nutrition is one building block that combines well with these habits and supports the skin from within.

The approach to sun in particular is a point that is easily underestimated. A moderate approach to UV radiation protects the skin in the long term, while a skin-conscious diet supplies the cells with nutrients from within. Both approaches work in the same direction without replacing each other. Smoking and excessive alcohol also have an unfavourable effect, so that an overall healthy lifestyle is the best framework for well-cared-for skin. Nutrition provides the building blocks, while good habits ensure that the skin is burdened as little as possible.

When a targeted nutrient intake can be useful

With a balanced diet, the requirement for skin-relevant nutrients is usually covered. With a one-sided diet or avoidance of certain food groups, a targeted supplement can be a topic, for example with zinc or vitamin A. This applies especially to people who eat little vegetables, nuts or animal products.

If you suffer from persistent skin problems, this belongs in the hands of a dermatologist – nutrition cannot replace a medical clarification. You should also not take preparations with fat-soluble vitamins such as vitamin A in high dosage without checking, since an overdose can be burdensome.

Frequently Asked Questions (FAQ)

Which foods are good for the skin?

Good for the skin are red bell pepper, citrus fruits, berries, carrots, sweet potatoes, green vegetables, almonds, sunflower seeds, eggs, fatty fish, whole grains and pulses. They provide vitamin C, vitamin A, vitamin E, biotin, niacin, riboflavin and zinc.

Which nutrients contribute to the maintenance of normal skin?

According to the approved EU claims, biotin, niacin, riboflavin, vitamin A and zinc contribute to the maintenance of normal skin. Vitamin C contributes to normal collagen formation for the normal function of the skin.

How do I support the absorption of skin-friendly nutrients?

Fat-soluble nutrients such as beta-carotene, vitamin A and vitamin E are absorbed better with some fat, such as oil, avocado or nuts. Vitamin C is heat-sensitive and is better preserved with gentle, fresh preparation.

Does drinking a lot help the skin?

The skin depends on a good fluid supply, which is why sufficient drinking makes sense. Water and unsweetened teas are ideal for this. Drinking, however, is only one building block alongside a balanced diet and suitable care.

Can nutrition solve skin problems?

A balanced diet supports the normal function of the skin but does not replace medical treatment. With persistent skin problems you should consult a dermatologist instead of relying on nutrition alone.
