You're making exactly the mistake that tempts journalists to write these sort of moronic stories. All things cannot be characterised into those that are 'good for us' and those that are 'bad for us'. To assume they can is idiotic.
Imagine you're a scientist for a second (as difficult as that might be). You have an unlimited budget (chance would be a fine thing). Now, design a study to tell me whether salt is good or bad for you. What does that study look like?
A study was published recently about the relationship between alcohol and heart disease. It was almost certainly the best study there has ever been in the field and it addressed a huge number of biases which previous studies have suffered from. The world's leading epidemiologists can still not agree whether the results show that drinking moderately protects you from heart disease or not. So what chance of any journalist writing a coherent article on the subject?
(In case you were wondering, even if there is a protective effect for heart disease, the increased risk of suffering from other health conditions almost certainly means that any amount of drinking is bad for you, and there is absolutely no evidence that red wine is better than anything else, that's just fantastic marketing by the industry).
