Breakfast cereal
This is the most marketable product in the supermarket - that's why they have an aisle all to themselves. Most cereals are made from the same ingredients - refined wheat and sugar - and will cause your blood sugars to spike. Just because they include the word 'breakfast' in their name, doesn't mean they should be eaten in the morning (or at all).
Instead: Go with homemade muesli topped with Greek yoghurt, or cook up some some eggs with tomato and avo.
Tea drinks
Don't get me wrong, tea is healthy, especially when you brew it yourself. However, the iced tea drinks purchased in bottles and cans are often extremely high in sugar, flavourings and additives.
Instead: Put the kettle on and make yourself a green tea. If it's too hot for boiling water, let it cool naturally.
Low-fat, flavoured yoghurt
Yoghurt is a very nutritious source of protein and calcium. However, when the fat is removed to satisfy our desire for 'lite' products, food manufacturers throw in a heap of sugar or sweetener to make it sell. This will cause more havoc in your body than the fat. Instead: Choose natural yoghurt and add your own fruits to flavour, or make your own.
Organic processed food
Ever bought organic chocolate and thought you were making a good choice? Unfortunately, many organic processed foods match their conventional counterparts in sugar and fat. However, this doesn't mean all organic food is bad. If you're eating wholefoods then you're definitely on the right track. However, "organic" is a term flung around these days, so always check the nutrition label before making your choice.
