Stress, pollution and an unhealthy diet can wreak havoc with skin, causing adult acne, early wrinkles and age spots. Turmeric combats free radicals. These are naturally present in small quantities in our bodies, but when their numbers increase it can have a detrimental affect on our health. Large amounts of free radicals can cause premature ageing skin and cellular mutations that may lead to certain cancers. By adding turmeric to your dishes, you can limit the proliferation of free radicals. At the same time, it's best to choose a high-quality turmeric. You should go for tumeric that contains at least 95% curcumin.
