The Top 5 Nutrients

 

Healthy skin is often viewed the result of good genes and an effective skin-care routine. However, studies suggest that the old saying “you are what you eat” couldn’t be truer. Just as some foods are associated with skin damage, some foods have a protective effect for the skin. Before we dive into the foods you need to be eating. Lets take a look at the five key nutrients for healthy skin:

1. Vitamin C

 

vitamin-c-healthy-skin

Vitamin C – Great For Healthy Skin

 

You know vitamin C boosts your immune system, but did you know that it also promotes radiant skin? A study published in the American Journal of Clinical Nutrition found that individuals who consume foods rich in vitamin C have fewer wrinkles and age-related dry skin than those who don’t.

Vitamin C is an antioxidant that protects your body from harmful molecules called free radicals. Free radicals damage collagen, the fiber responsible for your skin’s elasticity, which leads to wrinkles. Foods that are rich in vitamin C include strawberries, blueberries, oranges, kiwis, papaya and sweet potatoes.

 2. Vitamin E

 

vitamin-e-youthful-skin

Vitamin E For Youthful Skin

 

Like vitamin C, vitamin E promotes healthy, youthful skin by protecting your skin against free radical damage. Vitamin E-rich foods include almonds, avocado, hazelnuts, pine nuts, spinach and sunflower seeds.

 

3. Selenium

Selinium – Ideal for Healthier Looking Skin

 

In addition to protecting your body against skin cancer caused by sun exposure, the mineral selenium also delays aging by protecting your skin’s elasticity. High-selenium foods include Brazil nuts, fish, eggs, tomatoes, broccoli, shrimp, and lamb.

 

4. Vitamin A

 

vitamin-a-skin-care

Vitamin A – Found in Skin Creams For a Reason!

 

You may have noticed that your favorite anti-wrinkle product contains vitamin A; this is no coincidence. In addition to supporting healthy vision, vitamin A also improves skin health by causing your body to produce more collagen. Increase your vitamin A intake by adding carrots, oranges, cantaloupe, sweet potato, kale and/or squash to your diet.

 

5. Omega-3 Fatty Acids

 

omega-3-reduced-inflammation

Reduced Inflammation with Omega-3

 

Also known as the “good fats”, omega-3 fats reduce your body’s production of inflammatory compounds–the natural chemicals involved in the aging process. The result: healthier, younger-looking skin. Walnuts, flaxseed, canola oil, tuna, and salmon are all great sources of omega-3 fatty acids.

Best Foods For Healthy Skin

First and foremost, it is worth understanding the importance of antioxidants for our skin. You will also find there is an abundance there within our tea and coffee. However, what other foods are great for our skin and why?

1. Oily/Fatty Fish

 

Vitamin A Hormonal Acne

Oily Fish – Salmon

We’ve actually touched on the benefits that fish has for our skin in our piece on food to avoid but let’s get into the details here. Firstly, fatty fish constitutes fish such as mackerel, salmon and herring. They are rich sources of omega-3 and that’s the key to maintaining skin health.

 
Omega-3 Is the Key

 

Omega-3 will do wonders for your skin due to so many reasons. Firstly it keeps the skin thick, supple and moisturized. As demonstrated in this research, a deficiency in omega 3 can even cause dry skin. Omega-3 doesn’t stop there either; it reduces inflammation and can even reduce the affects of harmful UV rays from the sun.

As mentioned in our antioxidants post, Vitamin E does wonders for the skin and fish is a great source for this wonder vitamin. Lastly is the Zinc content, fatty fish is high in Zinc and this has been shown to be important for the production of new skin cells, without Zinc you are at an increased risk to skin inflammation, lesions and a delay to healing wounds.

2. Walnuts

 

Walnuts For Healthy Skin

 

Following on from the Omega-3 content in fatty fish, we have the humble Walnut. Rich in essential fatty acids that your body cannot make itself this nut has more omega-3 and omega-6 content than almost all other nuts.

 

The only warning is to be careful with Omega-6. A diet too high in this omega may lead to inflammation but due to the good ratio of omega-6 to omega-3 in Walnuts they have our seal of approval. If you’re still not convinced, walnuts are high in Zinc and contain Vitamin E, C and selenium – all key nutrients for healthy skin.

3. Sweet Potatoes

 

sweet-potato-healthy-skin

Sweet Potatoes for Healthy Skin

 

Let’s briefly move away from all those omegas to bring the nutrient rich sweet potato to the front. Sweet potatoes are an excellent source of Beta-Carotene – this effectively functions as Provitamin A which means it can be converted to Vitamin A in the body.

Beta-Carotene can be found in other vegetables too such as carrots and spinach.

When consumed, Beta-carotene acts as a natural sunblock to keep your skin healthy and can even give your skin a healthy and warm glow.

4. Tomatoes

 

tomatoes-healthy-skin

Tomatoes For Healthy Skin

 

Following in similar vain, the Tomato is another great source of beta-carotene as well as many other nutrients such as Vitamin C plus all major carotenoids.

 

Carotenoids such as lutein and lycopene have been shown to protect your skin from the sun and reduce the signs of aging by potentially helping to prevent wrinkles.

 

A quick tip with tomatoes is to pair it with a source of fat  such as cheese or olive oil. Fat will increase the absorption of carotenoids so it’s a great excuse to add some fat to your tomatoes…

5. Avocado

 

avocado-healthy-skin

Avocados For Healthy Skin

 

Last but certainly not least is the Avocado, we could have chosen from a plethora of foods but it had to be this one. No doubt you’ve already tried this super fruit that is now more popular than ever. What you may not have known is the vast benefits it can have on our skin.

Avocado is high in healthy fats, which is great for skin flexibility and skin moisture. In fact, a study with over 700 women found that a high intake of total fats from foods like avocado improved the skin, reduced wrinkles and made the skin more supple.

 

Not only is it high in healthy fats, the avocado also contains many of the important nutrients we have mentioned previously such as Vitamin E and Vitamin C.  An added bonus is that avocado has been shown to suppress the inflammatory response caused by UV damage.

 

A Balanced Diet

 

Hopefully this list has given you a few ideas and some encouragement that foods great for our skin are not too difficult to find.  If you do your best to follow a balanced diet you’ll no doubt incorporate many of these nutrients into your diet anyway. A couple of other foods to aim for would be; sunflower seeds, red peppers, soy, green tea and even a few bonuses such as dark chocolate and red wine can be great for your skin in moderation!

<h3id=”avoid”>Foods To Avoid

 

I think by this point you should have an idea on what foods are great for our skin. I’m sure there are no surprises in there! When it comes to food to avoid, not all food has been created equal. Some you might be able to get away with, others you should avoid at all costs.

 

Worst Foods For Our Skin

Worst Foods For Our Skin

 

As we have established, If the food is good for you, healthy and green it’s always good for the skin. On the flip side, bad foods, fast foods and alcohol are not so good for your skin. It’s a pretty good rule of thumb to work from but there could be a few surprise foods that are affecting your skin in ways you didn’t know.

High Glycemic Carbs

 

toast white bread skincare

High GI Foods – Bad for the Skin

 

We’ll start with what feels like an obvious one. We already know these foods are not great for our general health. However, high glycemic carbohydrates also negatively affect our skin. These foods can be anything from White Rice and White Bread to pure sugar. There are several reasons we want to avoid these foods, for reasons that affect both our skin and general health.

Firstly, these foods trigger sebum production. Sebum is an oil we want to avoid if we’re suffering from acne. This oil blocks up our pores, which can go on to cause spots and even cysts. Further to this, High GI foods stimulate androgen synthesis (male hormones). This hormone advances the development of acne so try to avoid where possible. Take particular care if you are suffering from acne already, as these foods can exacerbate the problem.

 

Blood Sugar Levels

A third and final reason you should look to avoid high GI foods is in the risk of increasing your blood sugar levels. An increase in the sugar in the blood can cause various problems. As an example, any sugar that isn’t picked up by the liver can get into your collagen supplies, which as we know, is the key protein to healthy skin. When the sugar infiltrates your collagen, your body identifies these cells and considers them damaged. Your body will then work to break down these ‘damaged’ cells, at the detriment to your skin. In all, it’s important to protect our collagen levels as much as possible so bear this in mind!

 

Bottled Water

 

bottled-water-bad-for-skin

Bottled Water – Bad for the Skin?

 

We promised you some foods you wouldn’t have thought of, so here’s a clear one for you, although we admit it’s actually a drink!.. Believe it or not, bottled water comes with its risks. The BPA in water bottles is known to be what is called a ‘steroid analogue’. This effectively means it could act like hormones in your body. The jury is still out on how much this affects your skin but we recommend using a more sustainable solution for bottled water. This way you’ll avoid any negative effects.

 Dairy

Dairy – Impact on Acne

 

This one, you may have known already. However, the studies may not be as clear as you think. Research has shown a correlation between dairy and acne but no clear causation. It’s hard for dermatologists to make a clear call on dairy since most of the time our yoghurts, cakes and general dairy also contains a lot of sugar. Therefore making judgement a little more challenging. We recommend consuming dairy that does not contain sugar and opt for cows that have not been treated with hormones – these are no good for your skin!

Spicy Foods

Spicy Food – Can Inflame The Skin

 

If you love spiced foods then we’re sorry to say this might be affecting your skin negatively. Spicy foods can trigger inflammation and flushing so if you suffer from rosacea then its best to avoid where you can.

In all, there’s a few key foods to avoid but its mostly a case of moderation. Try not to overdo it with the foods listed above and you’ll find your skin in good condition. If you’re noticing a rash or spot then you can of course speak to our board-certified dermatologists or even try our AI skin image searcher for an instant result.

 

Milk and Dairy – Bad for the Skin?

Acne Caused by Dairy?

 

You may have noticed we included dairy in our foods to avoid. We’re often told milk is good for us, so how can this be? Unfortunately, milk and dairy could trigger acne…

 

Does Dairy Cause Acne?

 

Post adolescence acne face artificial intelligence (AI)

Post Adolescence Acne

 

Acne, also known as acne vulgaris, is a skin condition that occurs when oil and dead skin cells clog your hair follicles. Symptoms of acne include blackheads, whiteheads and pimples.

Although there’s no definitive link between dairy and acne, recent studies have shown strong associations between the two. A 2008 study discovered that teenage boys who drank milk experienced more frequent and severe acne breakouts than those who didn’t drink milk.

How might dairy and acne be related? Researchers believe the hormones in dairy products ― particularly in cow’s milk ― are the culprit. When you consume cow’s milk, the hormones naturally found in the milk increase your body’s production of sebum, the oily substance that clogs your pores. This often results in acne.

If you need treatment to prevent or stop acne, ask a dermatologist!

 
What You Can Do

 

The best way to find out if dairy is negatively affecting your skin is to go dairy-free for a month and note any changes to your skin. If that’s not a sustainable lifestyle for you, there are some ways you can reduce your risk of acne while still consuming dairy:

        1. Switch from Skim to Whole Milk

A 2016 study found that the consumption of low-fat/skim milk was positively associated with acne. Researchers in this study, however, didn’t see the same correlation in full-fat milk consumption. This is because skim milk contains enough hormones to have biological effects in consumers. For instance, skim milks often contain proteins like whey and casein to make it taste less watery. These proteins release a hormone called IGF-1, which is known to trigger acne.

 

       2. Try Different Kinds of Dairy

If you notice that cow-based dairy products are causing you to break out, try dairy from different sources. Dairy from other animals, like goats, for example, may have less harmful effects to your skin.

Our Advice

For healthier, clearer skin, reduce your dairy intake and avoid skim milk whenever possible. If you cut dairy from your diet, be sure you still get the recommended 1300 milligrams of calcium a day by adding calcium-rich foods like kale, mustard greens, broccoli, and sardines to your diet. If you think dairy products are destroying your skin, ask a dermatologist!

 

Sugar and Sodium – The End Of Healthy Skin

Despite the many ideas above on what to add and avoid, there are 2 key ingredients that damage your skin most. Sugar and Salt. We’ll start with sugar and move on to salt. Read on below for more information!

 

How Sugar Ages your Skin

 

anti-aging, wrinkles, skin damage, acne, sugar

Sugar Causing Acne?

 

We all know that sugar is bad for your teeth and waistline, but what about your skin? Recent studies have found that consuming too much sugar can have damaging effects on your skin. Specifically, sugar-heavy diets can accelerate the aging process and cause acne. So if you’re looking for another reason to quit sweets, you’re in for a treat.

Sugar Affects Aging

 

Sugar increases the effects of aging through a natural process called glycation. Glycation occurs when the sugar molecules in your bloodstream bind to proteins to make harmful molecules called advanced glycation end products (AGEs). And that’s exactly what these molecules do — age your skin. AGEs damage surrounding proteins, and the more sugar you eat the more damage they do. The proteins most vulnerable to AGE harm are collagen and elastin, the two protein fibers that keep your skin firm and elastic. When AGEs damage collagen and elastin, the result is wrinkles and sagging skin.

As if that weren’t enough, AGEs also deactivate your body’s natural antioxidant enzymes, which protect your body from sun damage. This leaves you more susceptible to sun damage — the main cause of skin aging.

 

How Sugar Causes Acne

 

Many experts believe that excess sugar consumption may be linked to acne. In a 2007 study, subjects that switched from a high-glycemic diet (foods that cause a spike in blood sugar) to a low-glycemic diet showed a significant decrease in their acne over a twelve-week period, while a control group who maintained a high-glycemic diet did not.

What explains the link between sugar and acne? Eating high-sugar foods spikes your blood sugar, which causes your body to produce more insulin, a hormone that regulates the amount of glucose in the blood. Here’s the rub: as your insulin level increases, it prompts your body to produce more skin oils that may clog your hair follicles and result in acne.

 

Minimizing Sugar’s Effects on Your Skin

 

Cutting all sugar from your diet is both unrealistic and unnecessary for achieving healthy skin. What is necessary, though, is an honest effort to minimize your sugar intake. Here are a few practical tips to help:

 

   1. Opt for Complex Carbohydrates

anti-aging, wrinkles, skin damage, acne,

 

Simple carbohydrates —like white bread, pasta, ice cream, candy and soda — are rapidly converted into glucose and result in insulin spikes, which may lead to acne. Reduce your consumption of these foods and opt for complex carbohydrates, like fruits and vegetables, brown rice, beans, nuts, brown pasta, couscous, basmati rice and legumes. These foods are broken down into glucose at a slower rate, and thus don’t lead to acne-causing insulin spikes.

 

   2. Take at least 1 mg of vitamins B1 and B6 a day.

 

anti-aging, wrinkles, skin damage, sugar, acne, vitamin

If you have a sweet tooth and can’t afford to give up those snacks, there’s another option. A 2015 study found that Vitamin B1 and B6 are proven AGE inhibitors. While these vitamins can be found in various foods, taking a multivitamin that includes both guarantees you’re getting your daily value.

 

   3. Eat more antioxidants

anti-aging, wrinkles, skin damage, antioxidants, sugar, acne

Antioxidants help prevent sugar molecules from attaching to proteins. To help prevent the formation of AGEs, eat more antioxidant-rich foods, like strawberries, raspberries, blueberries, pinto beans, cranberries, and blackberries.

 

The effect sugar has on your skin is anything but sweet. For healthier, younger-looking skin, reduce your sugar intake and opt for complex carbohydrates when possible. If you think sugar is destroying your skin, ask a dermatologist!

Sodium – The effect on our Skin

 

salt-puffy-eyes

Salt – Bad for your skin

 

The average American consumes 3,400 mg of sodium a day, well over the 2,300 mg recommended by the Center of Disease Control and Prevention. Many of us know that consuming too much sodium spikes your blood pressure, which increases your risk of stroke and heart disease. But did you know that high sodium intake affects your skin, too?

Puffy Eyes

A tell-tale sign of a sodium-high diet is puffiness around the face — especially under the eyes. This is because salt causes your body to retain water.

Your body tries to maintain a water/sodium ratio that is approximately the same as seawater. When you consume sodium, your body retains water to maintain that same ratio. Water retention subsequently leads to puffiness around the body, usually affecting the extremities, belly and face. The skin under your eyes is particularly susceptible to swelling as it is very thin.

To learn more about the different causes of puffy eyes, ask a dermatologist.

 

Dry Skin

 

If you consume high amounts of sodium and don’t drink enough water, you’ll likely experience dehydration. Symptoms of dehydration include dizziness, dry mouth, headache, and of course, dry skin.

Sodium limits the amount of water your internal organs receive. In response, your organs take water from your skin. The result: dry skin.

And unfortunately, dry skin leads to another skin problem–acne. To compensate for this loss of moisture, your skin may overproduce oil. This excessive oil may clog your follicles and result in acne.

If you need treatment to prevent or stop acne, ask a dermatologist!

 

Counteracting the Effects of Sodium

 

The best way to prevent salt from negatively affecting your skin is to reduce your intake to 2,300mg a day. If this is not possible, here are some ways to counteract the negative effects of sodium:

 

1. Drink Plenty of Water

salt, puffy eyes, skin care

Consuming more water than usual  is very important to offset the effects of sodium on your skin. As water flushes out your system, it takes excess sodium with it.

2. Eat Potassium-Rich Foods

 

salt, skin care, puffy eyes

Potassium-rich foods help balance your body’s sodium level. While sodium causes your body to retain water, potassium helps your body reduce water retention. High-potassium foods include carrots, raisins, spinach and bananas.

 

3. Use Alternatives to Salt

 

puffy eyes, salt, skin care

Instead of using salt, try seasoning your food with fresh herbs, peppers, lemon juice or balsamic vinegar.

 
4. Reduce Your Bread Consumption

puffy eyes, skin care, salt

We’ve mentioned it once already, but consider reducing your consumption of one of the saltiest foods: bread. According to the Center of Disease Control and Prevention, breads and rolls are the leading sources of sodium intake in the United States. If you must have bread, opt for whole-wheat bread.
