The simple answer is yes. Environmental factors, nutritional status and dietary intake more than genes can add years to a person’s appearance. While topical applications make a difference, a healthy glow is more often a sign of internal health than anything else. There is a growing body of evidence to show that what we eat certainly influences skin aging and not surprisingly, the dietary correlations that relate to reduced skin aging also relate to reduced aging in general. Apart from dietary interventions, research is showing that supplementation with specific nutrients and antioxidants supports the use of topical anti-aging products and that in fact the combination is more effective than either treatment alone. Below is a review of the most significant dietary and nutritional influences on aging.

An Australian study at Monash University looked at the effects of food and nutrient intake on skin wrinkling in areas exposed to the sun. The participants were from Melbourne, Greece and Sweden.

Food intake questionnaires were used to measure diet and microphotography of the skin was used to measure skin wrinkling. The study showed that Swedish had the least skin wrinkling, followed by Greeks and Australians had the most. The types of foods consumed did have an effect on the degree of skin wrinkling with more damage seen in those with a higher intake of meat, dairy and butter. Foods that had a protective effect against skin wrinkling included vegetables, legumes, olive oil, tea, prunes and apples (see full list below). Overall, positive dietary habits trended towards a low-GI diet.

Another study supports the above food associations showing that skin wrinkling in a sun-exposed site in older people of various ethnic backgrounds may be influenced reducing intakes of fats and carbohydrates and increasing antioxidants and beneficial fats, dietary measures which are associated with better skin-aging appearance.

It is worth noting that research linking skin aging and dietary habits should not be taken out of context. Overall dietary trends produce these effects rather than any single food group in isolation. However, the dietary trends in both studies show that high GI and saturated fats seem to have the most significant pro-wrinkling effect. Due to their higher saturated fat content meat, dairy and butter can increase skin inflammation and lead to faster skin aging. In addition a high sugar intake is also associated with greater skin wrinkling. Simple sugar has a pro-inflammatory effect but it also promotes the production of advanced glycosylation end products (AGE). AGEs are closely associated with oxidative stress. A combination of a high antioxidant diet and low sugar reduces inflammation, free radical damage and AGE production in the body. Again the trend shows that the protective foods are low or have no saturated fats and are low GI and rich in phytochemicals which support skin collagen and reduce inflammation.

The Monash study indicated that these foods associated with less wrinkling:

• Mono-unsaturated fat including those from olive oil and olives
• Nuts and legumes
• Vegetables
• Fish (particularly those rich in essential fatty acids)
• Low fat milk and milk products, such as yogurt
• Wholegrain cereals
• Fruit and fruit products (especially prunes, cherries and apples)
• Eggs
• Tea and Water

More wrinkling was associated with diets that included higher intakes of:

• Saturated fat (including butter)
• Trans fats (including margarine)
• Meat (especially fatty processed meats)
• Full fat dairy products
• Refined carbohydrates and sugars such as cakes, pastries and desserts
• Soft drinks and cordials
• Confectionary of any kind
• Many packaged and processed foods contain hidden sugars
• Packaged cereals

Vegetables are the basis of a healthy diet

Apart from dietary trends, certain nutrients also show promising effects on skin aging. Studies have shown that antioxidant nutrients, specifically vitamins C and E, as well as lipoic acid and flavonoids, exert protective effect against oxidative stress in the skin, in particular photoprotective effects. That is they help protect the skin from the oxidative damage caused by the sun. Lycopene, lutein, and zeaxanthin as a specific subset of carotenoids may also be used as oral sun protectants and contribute to the maintenance of skin health. In fact, taking carotenoids prior to sun exposure will increase the depth and lasting effect of a sun tan (not that extended tanning is advised).

In other research, a daily dosage of soy isoflavones (40mg per day) resulted in the improvement of fine wrinkles and increased skin elasticity after 12 weeks of supplementation in middle-aged women with aged skin. Interestingly, a common arthritis supplement glucosamine also improved the appearance of visible wrinkles and fine lines. Glucosamine is incorporated into glucosaminoglycans (GAGs) in the body. GAGs work to increase epidermal thickness and elasticity of the skin although they have no effect on skin hydration.

A rich source of proanthocyanidins

Research into oral proanthocyanidins flavanoids from grapeseed extract or pycnogenol has shown they both have a significant protective effect on the collagen matrix of the skin and capillaries. They work by reducing capillary fragility and inhibiting collagen, hyaluronic acid and elastin breakdown. Both substances also have an anti-inflammatory effect and can improve peripheral circulation.

Again it is important to note that while supplemental nutrition can support skin health in a number of ways, if concurrent dietary changes aren’t made, the supplements will be combating the constant inflammatory cascade from high GI foods and saturated fats. Removing these dietary items will ensure that inflammation, AGEs and oxidation are all reduced allowing the supplements to work to their optimal level and effect real changes in skin health.

Watching teenagers grow into their lanky bodies, we consider acne and braces almost part of their natural evolution. But many adults can suffer from ongoing acne well into their adult years. It is estimated that 40-54% of men and women over age 25 are still plagued by acne.

Not surprisingly, women have often tried many, many products, treatments, as well as prescription medications before finally searching help from a professional natural health care professional. They have spent literally thousands of dollars on these ineffective treatments and they are anxious to see results quickly.

I always have to explain that acne has several contributing factors that all need to be addressed for optimal results and it often takes weeks to months to see very obvious results with natural therapies. This is especially true if they’ve been on antibiotics or Roaccutane for their acne. I don’t make the rules, I’m just the messenger. But the good news is—once the fundamental cause of the acne is addressed, breakouts become are rare or complete resolved.

I believe knowledge is power, and when people are educated about the cause of their illness and are provided the proper information, they gain a sense of empowerment that they are part of their own health care and they then feel more inclined to make the right choices.

So with that in mind let’s take a look at some of the cause of adult acne.

Hormones
It is a well established fact that hormonal fluctuations can cause acne— the reason for this could be twofold. Firstly, we know that the skin of acne sufferers contains higher concentrations of the enzyme that converts testosterone to dihydrotestosterone, a potent androgen (male hormone) that can increase oil production in the skin. This oil production can trap normal skin bacteria, which feed on this oil, and cause typical acne lesions. Yes, even women make testosterone. Many oral contraceptives control acne by indirectly controlling this conversion.

Androgenic control is a very important part of any good treatment plan for adult acne.

Lemons help with liver detox

Another reason why acne often worsens around the period is inefficient liver clearance of hormones. Improving liver function is a good strategy for this type of acne. Liver “congestion” can be caused by an overload to the detoxification systems of the liver. Chronic chemical exposures (like for hairdressers, nail technicians, carpet layers, etc), bacterial and fungal endotoxins absorbed from the digestive tract, and dietary and cosmetic hormone disruptors all are examples of “liver congesters”

Skin Bacteria
Your skin has a natural flora, just like your digestive tract. Even in very severe cystic acne, this normal flora is commonly all you can find on lab tests. Normal skin species include Propionibacterium acnes (Corynebacterium acnes) and Staphylococcus albus. P. acnes is believed to release chemicals that break down fats in skin oil that convert into potent free radicals, thus promoting an inflammatory cascade. Topical tea tree oil on acne lesions can help with this bacterial overgrowth.

Diet
Our diet is often a plethora of potential acne causing villains! The no-brainers are trans-fatty acids, most processed foods, and very fatty foods. Dairy is also associated with acne.

A good start is to eliminate these foods form your diet and stick to a 45% Protein, 35% carbohydrate, and 20% fat diet.

This diet will stabilize blood sugars that have been shown to be a factor in chronic acne. Researchers found skin glucose tolerance quite out of range in patients with acne. When given insulin their skin improved. This echoes what naturopaths have been saying for decades: consumption of sugar worsens acne! Supplemental chromium may be helpful if you have problems with balancing your blood sugar.

Believe it or not, I often find that food allergies can greatly contribute to chronic acne. This is especially true for the type of acne that does not seem to be affected by the monthly period – ie remain constant throughout he month. Big culprits here are dairy products and wheat.

Nutrients
Rarely have I seen a patient that suffers from long standing acne that has adequate zinc levels. Zinc is involved in local hormone activation, wound healing, immune system activity, and tissue regeneration.

Vitamin A is also a no-brainer for acne treatment. Synthetic vitamin A is the

A rich source of betacarotene

prototype for Roaccutane—the conventional “big gun” of acne treatment. It is basically such high vitamin A doses that liver function has to be routinely observed. But vitamin A in smaller doses over longer periods of time can be also very effective. Unfortunately in Australia a severe phobia about vitamin A exists in the conventional medical community.

B5 (pantothenic acid) is another fairly important nutrient as this vital vitamin helps you to metabolize fats and oils as well as contribute to energy production. Some studies have shown very definite benefit with high dose B5 supplementation.

Topical Skin Products
One of the worst things you can do for your skin is to dry it out in hopes that this will stop the oil production that causes acne. So people use scrubs and antiseptics and wash their face multiple times a day. This is the worst thing you can do as this seriously dries out your skin and causes irritation and inflammation. Your skin will take that as a signal to produce more oil and therefore more acne lesions.

For daily skin care, you are in very good hands with Ananda and her organic skin care.

Topical B5 and B3 creams have also shown benefits in clinical studies and are sometimes prescribed through compounding pharmacies.

Conclusion
This article was meant as a basic overview and did in no way cover all possible natural treatments for acne. This skin condition is very amenable to natural treatments but patience is required. A must rule out, in my opinion, is liver congestion and digestive contributors. I also recommend professional guidance to make sure the treatment plan is individualized for you!

A Wonder Drink from The Healthy Skin Diet

Last month I bought a blender for the express purpose of making this Wonder Drink! And since then I have been drinking it every morning and I love it. Called the Lemon Detox Drink, one of our clients Kelly says it tastes like a tart lemon meringue. The recipe is as follows:

1/2 lemon (wash the outside)
1 tablespoon of soy lecithin (German is better than US variety)
1 tablespoon of flax oil (organic)
300mls of filtered water

Method: finely grate the rind of the lemon into the blender then squeeze in the lemon juice. Add the lecithin, flax oil and water. Blend for 1 minute until frothy. Pour and drink.

Why is this drink so good for you? Well the lemon has an astringent effect which means it stimulates the liver to release bile into the digestive tract to be eliminated. The bile contains stored toxins so effectively you are dumping waste from your liver. The lecithin and flax oil prime your digestive system for the day, particularly your fat digestion so again supporting the liver. And of course water is just plain good for you and helps flush out daily waste particularly via your kidneys.

In addition to all the good detoxing, flax seed oil supports the moisture holding capacity of your skin cells and has a anti-inflammatory effect thereby supporting your skin’s health.

Another client that has been having this drink on a daily basis told me her skin was less red and much more even toned. This was a result I didn’t necessarily expect but a good one nonetheless. For myself, my elbows are soft again. They were getting a bit dry and I was having to moisturise a couple of times a day. Now once is more than enough.

If you decide to try this drink, let me know how you go. I love hearing your feedback.
