What's Really In Our Food

Petra takes us inside one of NZ's biggest caged egg farms and what really makes our yolks so yellow?

Carbohydrates - friend or foe? Are potatoes making us fat, would we be better off eating rice or pasta? Petra digs the dirt on spuds.

Juice, Fruit Drinks, Fruit flavoured drinks - they're all fruit drinks but some can contain 100% fruit and some contain no fruit at all! So which is the best option? And what are we drinking when there's no fruit at all - just a cocktail of colourings, flavourings and sugar?

How much do we really know about what we're putting on our toast? Is there any nutrition in our favourite spreads or are they simply convenience in a jar laden with salt, fat and sugar?

Is choosing to eat red meat putting our health at stake? Roasted, grilled or fried its traditional kiwi fare but is how we cook it, thats the recipe for cancer? Are we eating too much, or should we even be eating it at all? What role does beef have in a healthy diet?

Is it a health tonic packed full of antioxidants, the secret to a long life, or a cancer causing drug? What exactly goes into our wine, and does it have any nutritional value at all?

Sure some biscuits are loaded with sugar, flavours and artificial colour, but are there good ones? And what about crackers, are they healthier? Tonight we discover that just because it's called a cracker it doesn't mean it's better for you than a chip.

We're a nation that's big on cheese, but we also have a very high rate of heart disease. Tonight we investigate the link. We also discover some good news for soft cheese lovers, and the bad news on mould.

Where do our nuts come from and are there any health risks? We also investigate the role nuts could play in lowering bad cholesterol, and providing our bodies with essential nutrients.

We all know chocolate is hard to resist but why? Petra sets out to find out what's in chocolate that makes it so desirable, and hopes to find some nutritional evidence that will justify our appetite for the stuff. Final.
