GBBO host Noel Fielding is about to become a dad for the first time!

Cravings for salt are quite obvious – usually, your body is crying out for some sodium. It can be a sign of stress – if you're stressed out, your body will be producing more adrenaline, and the adrenal glands need minerals to function properly. Salt cravings can also be an indication of low blood pressure, which can be common in the early stages of pregnancy.Plain rice with a tiny bit of soy sauce is a good option, as it's a complex carbohydrate that'll keep you fuller for longer. If you do go for crisps, try the lighter varieties that are lower in saturated fat and salt. As a rule, though, if you can see the grains of salt, there's too much on there!

Cravings for sugary foods are probably the most obvious – what with morning sickness, low moods and health problems, you're likely to be feeling a bit run down! Subseqeuntly, you'll be craving foods that'll give you a quick boost: simple carbohydrates like sweets, chocolate or white bread.Protein-rich foods (like eggs, dairy and meat) can help banish sweet cravings; they keep you fuller for longer, which can be great if you're battling long periods of nausea and can't stomach a lot of food. If you really need a sugar fix, though, go for fruit first – frozen berries can be great if you're craving ice cream, and exotic fruit like dried mango can be a good substitute for jelly sweets. If all you can think about is chocolate, go for the dark variety – it contains antioxidants that can boost the immune system, and there's less sugar.

Spicy food causes the body to release small amounts of endorphins (the same feel-good hormones you release when exercising), so maybe your hormones are making you feel a bit down.Spicy food isn't really bad for you – a vegetable curry, some chicken tikka or maybe a Mexican wrap with hot salsa aren't exactly weight-gain inducing. Just don't overdo it; your digestive system might not forgive you!

Sometimes, you just get the urge to eat anything and everything around you. This could be due to feeling down (thanks to yet more hormonal changes) or just feeling bored. Whatever your reasons, we can't vouch enough for knowing the difference between genuine hunger and emotional hunger.If you really need to consume something, try a hot or cold drink first. The temperature might distract your brain for a while, and ice has been a popular craving antidote among pregnant ladies for years – to the extent that, nowadays, ice lollies are the number 1 odd craving among mums-to-be!If there's literally nothing else that'll satisfy your craving, just go for it. Pregnancy is one time not to skimp on calories. In fact, you need an extra 300 calories a day to ensure a healthy baby.The only way you could be harmed by a craving is if you're only eating the food you crave – and therefore depriving your body of other nutrients.

Sour cravings could be linked to your digestive health, as they cause your mouth to produce a lot of saliva, which kick-starts digestion.Lemons ranked third in a recent study of unusual cravings, so something with a sharp citrus flavour could be just the ticket. Before you reach for the Haribo SourMix, though, try lemon sorbet, which is made with fruit juice and has less than 100 calories per serving. Alternatively, a citrus-based fruit salad or a glass of fruit squash could work wonders for your cravings.
