2 Must-Avoid Food Groups That Promote Sun Damage
Did you know that the right foods could do more for your skin than any sunscreen?
Most sunscreens on the market do more harm than good.
Bear in mind that while chronic, long-term sun exposure has been linked with skin cancer, slathering on high SPF sunscreen is not necessarily the antidote.
Especially when the sunscreen itself poses a toxic threat to the body.
Most sunscreens on the market contain vitamin A retinyl palmitate. This is because vitamin A is an antioxidant, which can slow down the aging of skin tissue.
While this sounds like a good idea, it turns out that vitamin A does just the opposite in the sunshine.
The FDA found that when vitamin A is added to sunscreen in the presence of sunlight, it actually speeds up the development of skin tumors and lesions. (1) The year-long study found that those who received vitamin A cream developed tumors and lesions 21 percent sooner than the control group.
If the added vitamin A isn’t enough to worry about, consider the long list of chemicals found in most sunscreens.
Of these chemicals, oxybenzone is the most common. It is found in 65 percent of all non-mineral sunscreens on the market.
Oxybenzone penetrates the skin in relatively large amounts. Studies have found that oxybenzone may cause allergic reactions and that it disrupts hormone function. Because oxybenzone potentially disrupts hormone balance, many experts warn against its use on children.
Manufacturers add antioxidants to sunscreen for sun protection. The problem with this, as the FDA discovered, is that certain topical antioxidants actually cause lesions and cancer once these creams are exposed to sunshine.
Must-Avoid Foods That Promote Sun Damage
The most current research on skin cancer and exposure to sunlight tells us that diet has a lot to do with how well we manage sun exposure.
A diet that is full of foods that contain sugar is more likely to contribute to the formation of AGEs (advanced glycation end-products). AGEs on their own promote the breakdown and aging of connective tissue and vasculature in the body.
Put simply: AGEs are the biochemical result of what happens when a sugar links up with a protein in the body. When sugars and proteins crosslink, collagen breaks down. In the skin, we see things like wrinkles and cellulite.
According to the Journal of Oncology and the Journal of Investigative Dermatology, one study showed that UVA rays are far more toxic to skin that has an excessive buildup of AGEs. (2)(3)
This means that we can do our body and our skin a favor by limiting the amount of sugar that we consume on a daily basis.
Besides sugars in sweets, sugars are also found in grains, breads, pastas, cereals, and potatoes. Much of the processed food on market shelves contains hidden sugars.
One way to curb a craving for carbohydrates or sugar: Eat fermented foods and drink probiotic beverages. These foods naturally keep disease-causing bacteria at bay while promoting an appetite for nutrient dense foods.
2. PROCESSED FOODS
Studies show that dietary antioxidants and specifically omega-3 fatty acids have been found to halt the progression of cancer and to protect against the development of skin cancer. (4)(5)(6)
This is one more reason to avoid processed foods and the standard American diet.
In the standard American diet, many foods that are rich in omega-3 fatty acids have been displaced by omega-6 fatty acids.
This means vegetable, canola, corn, and soy oil. These oils are ubiquitous in restaurants and used frequently in prepared convenience food. Cattle, hens, and other animals of agriculture and industrial farms typically eat a corn-based diet, which increases the amount of omega-6 fats that they offer.
The problem with a diet full of omega-6 fats is that these fats actually promote the development of skin cancer. (7)
This summer, make sure that your diet is full of these antioxidant-rich foods and healthy fats to protect yourself from harmful sun damage:
- Extra-virgin coconut oil: This is an excellent oil to cook with, as it can endure high temperatures. You can blend coconut oil into smoothies.
- Wild-caught salmon: Salmon contains astaxanthin, which offers 500 times more antioxidant protection than vitamin E and is several times stronger than vitamin A.
- Fermented fish oil: It is full of nutrients that benefit the entire body and help to protect against sun damage, including vitamin A and omega-3 fats.
- Green, leafy vegetables and colorful berries: Both contain notoriously rich quercetin and other antioxidants.
- Body Ecology Vitality SuperGreen: If you are looking for a powerful blend of nutrients to add to a smoothie or have on-the-go, this is our favorite source of fermented, antioxidant-rich plant material!
What to Remember Most About This Article:
Eating the right foods could benefit your skin even more than slathering on sunscreen for a day at the beach. In fact, most chemical sunscreens on the market will do more harm than good when they are absorbed into your skin. While long-term sun exposure can lead to skin cancer, using a high SPF sunscreen with toxic ingredients could actually accelerate the development of skin lesions and tumors.
On top of that, how your skin reacts to the sun has much to do with your diet. Make it your top priority to avoid these unhealthy food groups that promote sun damage this summer:
- Sugars: A diet high in sugar contributes to premature aging in the skin, leading to wrinkles and cellulite. This process makes UVA rays even more toxic to cause serious sun damage. Curb sugar cravings fast by eating fermented foods and drinking probiotic beverages!
- Processed Foods: A natural diet rich in antioxidants and omega-3 fatty acids can protect against skin cancer. For this reason, it's important to avoid processed foods that are full of omega-6 fatty acids from canola, corn, soy, and vegetable oil since these fats can promote the development of skin cancer. Include healthy fats in your diet like extra-virgin coconut oil instead.
