Did you know that the number one cause of aging skin is sun damage? Those fine lines, wrinkles, uneven skin color, brown spots and broken blood vessels are all due to exposure to the sun’s ultraviolet rays. Unfortunately, precancerous areas called actinic keratoses appear on sun-damaged skin, and eventually lead to skin cancers. Thankfully, most cases of skin cancer are preventable, and nature offers options for improving the appearance of sun-damaged skin. Continue reading “Summer Skin Care”
The Environmental Working Group has rounded up their 2019 Guide to Sunscreens. This list provides the best choices for safe and effective sunscreens. EWG rates thousands of sunscreens from 0 to 10. This is known as the ingredient hazard score and reflects known and suspected hazards of ingredients. The safest products are rated 0 to 2 (green). Products that are rated 3 to 6 (yellow) have moderate hazards to health, and from 7 to 10 (red) are considered high hazards to health.
This guide comes at around the same time that a study published in JAMA found that certain chemicals in most sunscreen products pose cancer risks. The study took blood test samples from participants after using sunscreens for 4 days. Continue reading “EWG Releases 2019 Guide to Sunscreens”
May is Skin Cancer Awareness Month. Skin cancer is the most common cancer in the United States and although many of us know the dangers of the sun, many people still continue to ignore the potentially damaging effects of the sun on our health. The good news is that skin cancer is one on of the most preventable and treatable of cancers. About 90% of non-melanoma skin cancers and 85% of melanoma cases are associated with exposure to ultraviolet radiation from the sun. By raising awareness of the dangers of unprotected exposure and encouraging sun-safe habits, we can change behaviors and save lives.
Here are some statistics from Skin Cancer Foundation. Continue reading “Protect Your Skin”
Despite what we know about being safe in the sun, skin cancer is the most common form of cancer in the U.S., according to the Centers for Disease Control. And the incidence rate of melanoma, the most deadly form of skin cancer, is increasing every year.
Here are 5 sun safety tips to protect you and your family against the sun’s harmful effects.
1. Keep it to SPF 30: SPF (sun protection factor) ratings are a measure of sunscreen’s ability to block UVB ratings (known for causing the most damage). Did you know that a higher SPF than 30 does little if anything to block any more UVB rays than SPF 30? The Environmental Working Group (EWG) actually warns against using higher than SPF 30 because it can give people false confidence on the effectiveness of the product, leading them to believe that they are better protected and can stay out longer without further application. In the end, this increases their exposure to damaging UV rays. Generously apply natural sunscreen products that protect from UVA and UVB rays with an SPF 30 rating. Reapply often and especially after being in water. Continue reading “5 Tips for Sun Safety”
Foods containing omega-3 fatty acids may help in the prevention of both early and late stage oral and skin cancers, according to a study published in the journal Carcinogenesis.
The focus was mainly on a type of cancer called squamous-cell carcinoma. This is one of the major forms of skin cancer affecting the outer layers of the skin (mainly made up of squamous cells). The researchers point out that squamous-cell carcinoma can also occur in the lining of the digestive tract, lungs and other areas of the body.
The research was carried out in vitro meaning, they grew cell cultures in a lab. They used cell cutlures from several different cell lines inlcuding both malignant oral and skin cancers, alongside pre-malignant cells and normal skin and oral cells. When the researchers carried out these in vitro tests by adding fatty acids into the cell cultures, results showed that omega-3 fatty acids induced cell death in malignant and pre-malignant cells and the doses that did not affect normal cells.
Professor Kenneth Parkinson, head of the oral cancer research group says:
“We found that the omega-3 fatty acid selectively inhibited the growth of the malignant and pre-malignant cells at doses which did not affect the normal cells.”
This is very promising for the prevention and possible treatment of oral and skin cancers.
Since omega-3s cannot be made in the quantities that our bodies require, it is essential to get them from diet. Foods like salmon, flax seeds, sardines and walnuts should be part of your diet. If they aren’t consider taking a good quality supplement like Pathway Super Omega.
