Moisture loss as we age. Good Fats.

What about the loss of moisture that occurs as we age? It's possible that consuming more monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) can help. These "good" fats also have anti-inflammatory properties, which may also help preserve our skin. In one study, flaxseed oil was given to volunteers with sensitive skin. After 12 weeks of daily consumption, the volunteers showed less irritation after exposure to an irritating substance. They also demonstrated less transepidermal water loss, which means their skin held on to moisture better. Their skin even exhibited less roughness.

What are some examples of good fats? A few examples of foods that supply fats and powerful nutrients include nuts [walnuts, Brazil nuts, almonds, pecans], seeds [chia seeds, ground flaxseeds], avocados, and fatty fish [such as salmon].
