With summer in full swing, it’s an ideal time to catch up on some much needed vitamin D. According to a Harvard study, an estimated 1 billion people are deficient in vitamin D. Unfortunately, wearing sunscreen blocks the sun’s ability to stimulate vitamin D production. Not to mention, skin cancer rates are rising despite more sunscreen use and reduced sun exposure. So what’s the answer? Safe sun exposure with protection from the inside out.
Because sunburn is an inflammatory process, eating an
anti-inflammatory diet full of antioxidants is a huge part of natural sun
protection.
Dr. Ronald Watson of the University of Arizona says
“antioxidants in red, yellow and orange foods build up under the skin creating
extra UV protection. The effect is so strong, that eating six portions a day
for two months will build a natural barrier equivalent to factor 4 sunscreen.”
Include these foods and supplements when EATING YOUR
SUNSCREEN:
Astaxanthin
Astaxanthin is such a superstar it deserves its own post.
It’s the number one nutrient to include in protecting yourself from sun damage.
It’s a member of the cartenoid family. Cartenoids are what give foods their
vibrant colors and protects plants and organisms from damage by light or
oxygen. When we consume them they give us a similar protective benefit. Astaxanthin is by far the most powerful
cartenoid and is thought to be the most powerful antioxidant. It’s 65 x more
powerful than vitamin C and 550 x more powerful than vitamin E.
Astaxanthin is the red pigment that gives salmon and
flamingos their pink color. It’s produced by microalgae as a survival mechanism
to protect itself from UV radiation, intense sunlight and a lack of nutrients
when its water source dries up. When we ingest it, it does the same for us. It
acts as a “radiation shield” and works as an internal sunscreen. Not only does
it protect us from the sun but it also reverses previous sun damage. It combats
all the tell-tale signs, including, brown spots, sunburns, wrinkles, fine lines
and skin cancer. Studies have shown that consuming 6 milligrams of astaxanthin
per day for 6-8 weeks can significantly reduce crow’s feet and the size of age
spots while improving skin elasticity and texture.
In Japan, a study was done in 2002 by Yamashita with
women around age 40 who consumed 2mg astaxanthin daily for four weeks.
Researchers were surprised that after only 2 weeks, almost every aspect of the
women's skin had improved; after 4 weeks, there was even more improvement.
Benefits included fewer fine lines, better moisture, increased skin tone and
elasticity, smoother surface, fewer freckles, and less under-eye puffiness
Astaxanthin is also beneficial when applied topically. In
2001, a study was performed on hairless mice to explore its topical benefits.
The mice were exposed to UVB radiation for 18 weeks to
simulate photo-aged skin. The mice that had astaxanthin applied to their skin
demonstrated reduced wrinkles when compared to the control group, as well as
younger-appearing collagen. In fact, the collagen of the astaxanthin mice
looked as if it had never been exposed to radiation.
Researchers concluded that astaxanthin "can
significantly prevent UV-induced collagen degradation, wrinkles, lipid
peroxidation, sunburn, phototoxicity and photoallergy."
The same study also discovered that topical astaxanthin can
act as an effective "skin whitening agent," which is an extremely
popular trend in Asia. Astaxanthin was found to reduce melanin by 40 percent,
greatly reducing freckles and age spots.
Perhaps the greatest testimony to astaxanthin working as
an internal sunscreen is Dr. Robert Child’s personal experience with it. Born
and raised in Honolulu, Hawaii, he was always extremely sensitive to the sun
and would burn within a half hour of sun exposure. But once Dr. Childs started
taking Astaxanthin, he found that he could go in the midday sun for four hours
without burning. Dr. Child’s says that “BioAstin (a brand of natural
Astaxanthin) literally changed my life, I am outdoors whenever and for as long
as I like.”
Lycopene
Lycopene, another member of the cartenoid family, is an
antioxidant which can enhance the skin’s natural defense against free radicals
by 35%. All red fruits and vegetables contain lycopene. Tomatoes are a great
source, especially tomato paste and sauce. Cooked tomatoes, offer far more
bioavailable lycopene than raw tomatoes. A study presented at the British
Society of Investigative Dermatology involving 20 people found that
participants who consumed tomato paste had 33 percent greater protection
against sunburns than participants who did not consume tomato paste. Watermelon
is an especially rich source of lycopene, offering 40% more than tomatoes.
Beta
Carotene
Beta Carotene, also a cartenoid, is a pigment found in
orange and green fruits and vegetables. Similar to lycopene, it is an
antioxidant that protects from sun damage. In addition beta carotene also makes
people less sensitive to the sun. Sweet potatoes contain the most beta carotene
of all fruits and vegetables. Other top sources are carrots, butternut squash
and dark leafy greens such as spinach and kale, romaine lettuce and cantaloupe.
Pomegranates
Pomegranates are loaded with antioxidants. According to
dermatologist Howard Murad, they can "enhance skin's sun-protective
properties by 25 percent".
Almonds
Almonds are one of the best sources of vitamin E, which
protects and repairs the skin from sunlight. Almonds also contain quercetin,
which has been shown to protect against UV damage and the wrinkle-causing
breakdown of collagen. One study found that after participants were exposed to
UV light, the participants who took the same amount of vitamin E found in 20
almonds had less sunburn than the participants who did not that amount of
vitamin E.
Epigallocatechin
Gallate (EGCG)
EGCG, one of the most powerful antioxidants and the most
powerful polyphenol there is, protects against UVA and UVB radiation and can
reactivate dying skin cells. Green tea contains high amounts but matcha contains 137 x the amount of
EGCG that green tea has.
Omega-3 Fatty Acids
Omega-3 fatty acids reduce inflammation and protect your
skin from sunburn. Wild Salmon, sardines, flax seeds, chia seeds and hemp seeds
are rich sources of omega-3’s.
Vitamin C
Vitamin C is a powerful skin protective antioxidant that
protects against sun damage, wrinkles and dry skin. Strawberries, broccoli,
citrus fruits, bell peppers and kiwi are rich sources of vitamin C. It is also
helpful to supplement with 3,000 mg of Ester C per day.
Vitamin
D
Our bodies produce melanin (dark pigment we get when we
tan) to shield the skin from further uv exposure. That is why those with darker
skin need more sun than those with fair skin to achieve optimal vitamin D
levels. When the body has enough vitamin D, it will start producing melanin to
keep from getting too much. Supplementing with vitamin D3 will help protect
your skin from uv rays.
Tips
Stay hydrated. Dehydrated skin burns much easier than
hydrated skin.
Avoid sugar and processed foods.
Cutting out grains is an easy way to incorporate more
antioxidant rich fruits and vegetables into your meals.
15-20 minutes per day is all it takes for most people to
achieve adequate levels of vitamin D. The darker your skin the more time you
will need to get enough vitamin D.
The sun is at its hottest between 11-2 pm. If you’re
going to be in the sun for an extended period of time or during peak hours make
sure to wear a natural sunscreen. Studies show that chemical sunscreens
actually cause skin cancer.
Suntegrity is an excellent natural sunscreen that uses 20%
non-nano uncoated zinc oxide (important that the zinc is non-nano uncoated) as it active
ingredient. It's facial sunscreen also contains astaxanthin.
When taking astaxanthin make sure you purchase a natural
form as many synthetic options exist. I highly recommend BioAstin, a natural,
Hawaiian astaxanthin.
