Alkaline diet: As Mother Nature intended?
'Honestly Healthy' author Natasha Corretts says giving up acid-forming foods not only reduced weight, but changed her entire life.
Five years ago, Natasha Corrett was overtired, overworked and unhappy with her weight. And when her back seized up in a stress-related spasm the day before her 26th birthday, she sought acupuncture treatment in a desperate effort to 'unknot her in time for her party.
What the gourmet cook didn't expect was advice on food that would revolutionise her diet, make her lose two-and-a-half stone "without noticing" - and find relief from the symptoms of polycystic ovary syndrome (PCOS) that had dogged her for years.
It was while she was having the needles inserted that the therapist told her about the benefits of an alkaline diet: one that avoids "acid-forming foods" such as dairy, meat, sugar and coffee, and replaces them with plant foods and wholegrains.
Now 31, Natasha is in radiant health and her series of best-selling Honestly Healthy cookbooks, based on the principles of alkaline eating, have a big celebrity following - one fan is Victoria Beckham.
The latest book to be published, Honestly Healthy Cleanse, contains 100 meticulously tested new recipes that combine her alkaline diet principles with four "cleansing plans" for a new eating regime.
Each detox is tailored to individual needs: the six-day slim-down cleanse, for example, suggests a menu of raw salads with soups and smoothies to inspire those new year weight-loss plans; while for those in search of something more ambitious, the 30-day "life-changing" cleanse is, she promises, a stepping stone to a, healthier life.
"Once you've achieved the first 30 days, there will be no turning back," she promises, "you will make definite lifestyle changes for the better as you'll feel so energised."
Natasha, who is engaged to Simon Bateman, 36, a fitness expert, comes from a family who know about food. Her mother, the interior designer Kelly Hoppen (Sienna Miller is her stepsister) was always a "health freak", she says, and the fridge at home was full of "dairy-free milk and similar products".
From her restaurateur father restaurateur, owner of fashionable Le Boudin Blanc in Mayfair, Natasha (pictured), developed a fondness for good food, learning to cook at his restaurant during her summer holidays. Like many of us, she admits she has always been torn between knowing what is "good for you" and not wanting to deny herself a dish she enjoyed.
So what led to her passion for "the alkaline way"? "Five years ago," she explains, "I was always on the go, making and delivering fresh food for my company Fridge Fill, working hard but not making a living, and feeling tired all the time.
"When I was at boarding school, it was fashionable to be really skinny and my weight fluctuated massively as I tried to fit in."
It was her mother who recommended a therapist specialising in Ayurvedic medicine as well as acupuncture. When he pointed out that Natasha's whole system was out of balance, she was more than ready to listen.
"The therapist told me my body had become incredibly acidic from years and years of yo-yo dieting, even though I thought I was super-healthy, being vegetarian and knocking back a green smoothie with spirulina every morning," she says.
"He suggested my body was in such a toxic state from stress and overwork that there was no way it could absorb nutrients. He said I needed to do an alkaline cleanse."
Claims as to the benefits of an alkaline diet are not new. Pioneered by Dr Robert Young, an American biologist, the theory is that the digestive process causes foods to become either alkaline or acidic, as measured by their pH levels. The results are sometimes counter-intuitive: dairy, for example, becomes highly acidic when digested, while lemons become alkaline.
Fans of alkaline eating maintain that while alkaline-forming foods help the body maintain healthy pH levels, too much acidity does the opposite; and that sticking to an alkaline diet can help with weight loss and bloating as well as improving digestion, skin tone and mood. An acid-based diet is blamed for diseases such as osteoporosis, heart problems, back pain and kidney stones.
"At first, I wasn't sure I wanted to try this way of eating," says Natasha. "I had promised myself I would never do another detox or diet, as I had become so obsessed with food and felt so unhappy. I had sworn never to put myself through that misery again. But I was persuaded to try an alkaline cleanse for 21 days, and I just didn't stop. I felt so well."
Gradually, the weight came off, while her symptoms of PCOS, acne, mood swings and bloating, disappeared as her hormones became more balanced.
Whether or not the theory holds up, much of the advice on alkaline eating chimes with official guidance on a healthy diet. Natasha advocates replacing acid-forming foods with alkaline foods - fruit, vegetables, pulses and wholegrains. Wheat is also considered acid-forming, while almonds, garlic, olive oil and herbal teas are highly recommended.
As Natasha points out, following this way of eating is mostly common sense and her delicious recipes prove it need not be painful.
"Think about eating as Mother Nature intended," she advises. "Make your diet plant-based, with lots of pulses and grains, although don't eat too much fruit - certainly not on an empty stomach, as that is very acidic."
She recommends following the alkaline pattern of eating 70pc of the week and then relaxing about the other 30pc. "And if you can't resist meat on a 30pc day," she says, "just be sure that all the meat you buy is organically and sustainably reared."
