Can you look younger by stuffing your face? Absolutely! The healthier the foods you consume are, the better your skin looks. No vitamin C and you’ll have no collagen.

Too little vitamin A or essential fats and you’ll have dry, rough skin, and too little zinc is a recipe for greasy skin and stretch marks.

So forget plastic surgery. For glowing, gorgeous, youthful skin, it makes sense to eat your way to fewer wrinkles, pimples, age spots and other beauty plagues.

Resurfacing your skin

It’s no accident that vitamin A is the number one vitamin used topically to improve the texture and appearance of ageing skin.

Vitamin A is a powerful agent for increasing cell turnover, so that skin looks more youthful.

This skin vitamin comes in two forms: retinol, the animal form found in meat, fish, eggs and dairy products; and beta-carotene, found in red, yellow and orange fruits and vegetables.

Apricots, carrots, sweet potatoes and pumpkin are all good sources of beta-carotene.

Sydney-based naturopath Penelope Sach, author of Natural Woman (Penguin), advises: “Include a raw carrot juice daily for the natural vitamin A content, which helps to regenerate skin cells. “

Foods to tighten and tone

Thanks to New York Times bestselling author Dr Nicholas Perricone, we now know that good skin is a very fishy business.

Fish is not only a good source of the antioxidant co-enzyme Q10 (CoQ10), but an outstanding source of high-quality protein that helps with cellular repair and essential fatty acids (EFAs), which are responsible for healthy cell membranes, he says.

EFAs hold water, so the stronger they are, the plumper and younger your skin looks.

Fish also contains a powerful antioxidant compound called dimethylaminoethanol or DMAE.

“This chemical stimulates nerve function and the muscles to contract and tighten under the skin,” says Dr Perricone in The Perricone Prescription (HarperCollins).

“It is a magic bullet for great skin tone, keeping your face firm and contoured.”

Sach says: “For radiant skin, eat cold-water fish such as salmon, mackerel or tuna, three times a week.”

Other good face firmers are walnuts and flaxseed oil, soya oil, pumpkin seeds and sunflower seeds.

Flaxseed oil may also be useful in the treatment of skin conditions such as eczema.
