Alpha linolenic acid is an essential fatty acid found in the oils of many vegetables. As an essential fatty acid, alpha linolenic acid works wonders for the aging complexion. Alpha linolenic acid falls into the category of a polyunsaturated or omega-3 fatty acid. Omega-3 fatty acids have been linked to numerous health benefits. The anti-inflammatory nature of alpha linolenic acids has proven effective in reducing the risk of coronary heart disease and certain circulatory problems.

How it works. The omega-3 fatty acids, like alpha linolenic acid, promote cell growth and renewal. Only a small amount of these fatty acids are needed in the diet to improve overall growth and health significantly. Alpha linolenic acid works to maintain a healthy rate of skin cell renewal while simultaneously reducing inflammation. Essentially, the alpha linolenic acid is converted into eicosanoids, molecules that control many aspects of the immune and nervous systems. Overproduction of eicosanoids can actually increase inflammation and exacerbate inflammatory conditions like arthritis and heart disease. However, Omega-3 fatty acids, like alpha linolenic acid, are beneficial because they produce eicosanoids at a slower rate the other omega acids.

Where they can be found. As an essential fatty acid, alpha linolenic acid cannot be produced by the human body but must be consumed through diet. The most common foods that contain alpha linolenic acid are those with seed oils like soybeans, walnuts, and flaxseed. Green, leafy vegetables are also a good source for alpha linoenic acid as are animals that eat a large diet of green, leafy vegetables.

Benefits for aging skin. Anything that promotes overall health in the body will help protect your skin from signs of aging. Alpha linolenic acid, however, also moisturizes the skin and reduces inflammation and other damage that may lead to wrinkles and other aging signs. While research on alpha linolenic acid has focused primarily on treating a wide range of inflammatory and cardiovascular diseases, this is definitely a nutrient we should try to include in our diet as we age.

The Mediterranean Diet. One of the recent diet crazes that centers around the inclusion of fatty acids and particularly alpha linolenic acids in the diet is the Mediterranean Diet. A balanced consumption of fruit, whole grain, green vegetables, and fish and seeds rich in essential fatty acids drive this diet. The avoidance of red meat and rich dairy products also plays a significant role in making this a very healthy diet to follow.

The combination of a balanced diet and exercise can help keep you healthy and young. But if those wrinkles and other aging signs are still forming, an anti-aging cream may be just what you’re looking for. Click here for information on the most effective anti-aging creams on the market.
