According to older beliefs, acne can be caused by excessive consumption of greasy foods and chocolate. Many dermatologists and other skin professionals now say that there is no proven scientific connection between food and acne. However, I prefer to believe that what you choose to put in your body will have a definite effect on your health, including your skin condition. Sugary foods, excessive caffeine, and greasy, fatty snacks—all have a negative effect on our bodies and overall health. Not drinking enough water also does not help in skin repair and formation of new tissue. If your skin is particularly susceptible to acne, having a poor diet will definitely not help the situation. It is known that eating too much sugar and refined carbohydrates can lead to a surge in insulin. This in turn may create a condition referred to as IGF-1, where an increase in insulin creates the production of excess male hormones. Excessive male hormones can create an excess of sebum, the greasy stuff that can clog pores, attract bacteria, and create monster zits. IGF-1 is also believed to cause keratinocytes to multiply, which can wreak havoc on skin. Doctors have consistently warned of the health dangers of consuming saturated fats and trans fats. Saturated fats have an overall negative effect on the body, weakening the immune system, promoting inflammation, and for acne sufferers, perhaps raising the skin's oil production level. To have the best complexion possible, keep your body healthy and filled with good, health-promoting nutrients. You should strive to reduce saturated fats because they promote inflammation, and will not help you in your battle against acne. Certain oils are, however, absolutely essential to your health. These essential fatty acids reduce inflammation, and help promote healthy skin, nails and hairs. Examples here include flax oil, olive oil, and fish oil. You should also ensure that you have an adequate supply of vitamins and minerals on a regular basis. Vitamin A is paramount for promoting healthy skin. Avocados and carrots are excellent sources of Vitamin A. Vitamin B-6, Vitamin C, and Zinc are other important nutrients for promoting a good complexion. Another aspect to consider in terms of diet is your food allergies. Sometimes, people experience severe cases of acne, even if they lead a very healthy diet and have never suffered from severe acne before. In these cases, the cause may be a potential food allergy. If you suspect your acne is caused by a food allergy, begin by increasing your daily amount of water consumption. Then try to rule out the root cause of your potential acne. Common causes of food allergies include dairy products, excess sugar, and certain refined flours and grains. Also, avoid foods rich in iodine, which have been linked to acne. Iodine-rich foods may include salt, liver, cheese, crabs, shellfish, clams, and kelp products. If you consume iodized salt, make the switch to sea salt. If you find dairy products worsening your acne, consider switching to soy or rice milk and cheese products. The only way to prove whether there is a link between your acne and food is first by making definite changes to your diet. Observe carefully and see if you are better able to control your acne through the diet changes. Even if your acne is not caused by diet, you gain in terms of having a healthier and well nourished body. It is likely that your physical appearance will benefit from a body that is not filled with junk food!
