"Our bodies are naturally alkaline, but our eating and drinking habits and the stress we endure creates acidity," says Ilona.
"This can cause weight gain, lethargy, bloating, bad skin, a suppressed immune system, concentration problems and all manner of other complaints."
Coffee, alcohol, processed foods, sugar, salt, dairy and too much red meat are all considered acidic for the body, explains Ilona, as well as our long-hours culture.
So how do we rebalance a pH that's out of whack? "Eating a diet that combines both some acid and more alkaline – a 20/80 split, ideally - has endless benefits," says Ilona.
How should you alkalise your body?
1. Swap processed food for fruit and veg
Cut down on the offending articles mentioned above, and introduce a greater concentration of fruit and vegetables to your diet, especially broccoli, fennel, kale, beetroot, lemon, grapefruit and dates.
Alkaline foods take the least effort for the body to digest, which frees up the body to do more important healing work.
Millie Mackintosh has made the switch and recent went for, "fennel and pear soup for dinner! #health #alkaline".
2. Reduce your sugar intake
Sugar is a major acid to try and eliminate from your diet, because it's addictive. And the only way to kick those sugar cravings is to alkalise the body and break the cycle of addiction, explains Ilona, because sugar doesn't satisfy for long.
If you're like us and have a sweet tooth, try baking delicious raw chocolate brownies, snack on plain yogurt with manuka honey and nuts, or make yourself a big alkalising fruit salad to dig into during the week - try one with mango, pineapple, melon and kiwi fruit.
3. Swap coffee for green juice
When you're feeling sluggish, it can be tempting to grab a coffee or bottle of fizzy pop, but this is the worst thing you can do for your body, as they're both very acidic.
Even if you do get a short-lived sugar high off that caramel latte or bottle of fizzy pop, you'll come crashing down later and feel even more rotten.
To curb acid cravings later in the day, drink a green juice at breakfast. Try a cold pressed juice to retain maximum goodness from your ingredients, and throw in courgette, broccoli, lemon, apple and fennel.
