Is your diet ageing you?

Your skin is your body’s largest organ. And what you eat and drink, feeds it. So if your diet is lacking, your skin will show it.

When it comes to your skin, you really are what you eat.

Studies have shown that eating antioxidant-rich and natural foods such as fruits and vegetables can contribute to a healthy glowing skin, giving you a more youthful, fresh appearance.

The flip side of this is also true: certain foods can sabotage your skin’s radiance and contribute to spots and patchy skin, generally having an unfavourable reaction which shows in the skin.

Foods to avoid


Apart from the fact that alcohol is a diuretic, which dehydrates the skin and can make wrinkles and lines appear more pronounced, binge-drinking often goes hand-in-hand with hangover-busting junk-food binges, which have an extremely negative effect on the skin.

Foods with a high sugar content raise the blood sugar levels which in turn can weaken the skin by affecting collagen, leading to wrinkles.

Foods high in salt can cause water retention, making the skin appear dry and puffy.

High GI foods
A diet high in starchy foods such as white breads, pastas and cakes causes blood-sugar spikes and has been linked to acne.
