The Alkaline Diet: What’s True, What’s Not, and Why It Still Matters

You’ve probably seen the alkaline diet promise a lot: more energy, better skin, fewer aches, even slower ageing. Some of that is hype. But underneath it there’s a principle I really do believe in, so let’s separate the two.

Can food change your body’s pH?

Not in the way it’s often sold. Your blood has to stay within a very narrow pH range, and your body works hard to keep it there no matter what you eat. Your lungs, your kidneys and a whole system of buffers all play their part. Food doesn’t tip your blood from “acidic” to “alkaline.”

What food can change is the pH of your urine. That’s your kidneys doing their job, clearing out the extra acid or alkali. It’s a sign your body is balancing things, not that your whole body has become acidic.

So why do people feel better on it?

This is the part I find interesting. When people “go alkaline”, they usually:

• eat far more vegetables, leafy greens and herbs
• eat less processed food, sugar and alcohol
• drink more water
• cook more at home

That’s simply a more nourishing way of eating. I feel the real benefit isn’t about pH at all. It’s that this way of eating is naturally anti-inflammatory.

Food and inflammation

Inflammation is your body’s way of protecting and repairing itself, and in the short term it’s exactly what you need. But when it hangs around in the background, it can play a part in so many of the things women live with: period pain, achy joints, skin flare-ups, low energy and digestive trouble.

A diet built mostly on plants is linked to lower levels of inflammation. Your body gets plenty of fibre, antioxidants and minerals, and fewer of the processed foods that can keep inflammation simmering.

So I’d call it less of an “alkaline diet” and more of an anti-inflammatory way of eating, with plants at the centre of your plate.

Alkaline-forming foods list

These are the foods traditionally called “alkaline-forming”, and they’re also the foundation of an anti-inflammatory plate:

• Leafy greens: spinach, kale, chard, rocket
• Vegetables: broccoli, courgette, carrots, beetroot, peppers, sweet potato
• Fresh herbs: parsley, coriander, basil, mint
• Lemons and limes
• Most fruit, especially berries
• Avocado
• Herbal teas

Acid-forming foods

Foods often called “acid-forming” include meat, cheese, processed foods, sugary drinks and alcohol. That doesn’t make them “bad”. Good-quality protein in particular is important, especially for your hormones. It’s about balance, not cutting things out.

A simple way to start

You don’t have to overhaul everything at once. Bit by bit:

• Fill half your plate with vegetables at lunch and dinner
• Add a handful of greens to soups, stews and eggs
• Start your day with warm water and lemon, if you enjoy it
• Swap one processed snack a day for something whole
• Keep protein in every meal, so you stay full and your blood sugar stays steady
