Salt and sugar:
Cutting down on salt can help you in many ways. But you would be doing your skin a great favor too by limiting your salt intake. Salt can lead to water retention and sugar can lead to inflammation and both these could deplete moisture in your skin and promote wrinkles and loss of elasticity. This is why you need to eat less processed foods and fast food which are loaded with excess sodium and fructose.
Simple carbs:
Simple carbs including foods made with refined flour are as bad as sugar. These can cause skin damage similar to sugar-laden products because of their quick conversion to glucose. Avoid these foods completely, if possible.
Excess of dairy products:
Paneer, milk, curd, etc. are all healthy foods, no doubt, but it is important to stick to moderation or else they could have detrimental effects on the skin. You should also find out if you are lactose intolerant, in which case, the problem exacerbates when you consume dairy.
