Don't panic, it's probably a normal phase many children go through. Try not to let her pick up your anxiety otherwise the message she gets is that mealtimes are something to fear.

Rule out basics like toothache, sore mouth or throat, mouth ulcers, tummy ache sore bottom(the most common complaint in my experience)and keep a note of bowel and urine movements, for example any diarrhoea or pain passing urine. Sometimes if a child has had a particularly painful or traumatic experience going to the toilet it can trigger this, especially if they are starting to make a link between food and tummy ache.

Try to keep a routine and offer her food, if she refuses, take it away with no fuss. Make sure she is drinking plenty of fluids.

Just try for a few days to have a calm, stress free mealtime and hopefully she will gradually start to forget her mini phobia.

If you don't have any luck that way, see a doctor but don't let them make the situation even more hysterical.At that age you would expect some fluctuation in weight so don't worry. Maybe you could go to Carrefour and buy some nice Disney plates and have toys that are for children who have been good at dinnertime. Making that time more exciting may be enough.

Any signs of illness should be taken very seriously as if it is enough to put her off food, it must be bothering her.
