What makes a food or drink healthy?

[blondfrog]

What qualifies a food as healthy I've never fully understood this and what can be healthy to one could be unhealthy to another. Say if someone had an allergey to a food or say an auto-immune disease that didn't allow their body to digest a certain food group like Celicas disease where one can't have anything with gluten in it which are in wheats. Or if someone can't eat dairy products cause they are lactose intolearnt and they don't have the proper enzymes to digest dairy products.

For something to be considered healthy it must contain nutrients, vitamins, and minerals, but also be low in cholesterol and saturated fat and free of refined sugars and preservatives. For example, though eggs contain nutrients, it is illegal and considered false advertising for companies to market them as "healthy" because they exceed the upper limit for cholesterol and fat content.
You're right though, depending on diseases or allergies, it might not be healthy for you to eat a certain food. However, just because a healthy food does not react well with you, does not mean that that food is no longer healthy.

Usually the absence of chemicals i the products themselves and lack of processing during production.
Oil for example is a highly processed, concentrated food that hardly qualifies has healthy, tuna these days is full of mercury, also not healthy

It depends on your individual needs, everyone is different so what may be healthy for me may not be so healthy for someone else, but generally your diet should be 40% protein, 40% carbs, 20% fats

Low sugar, sodium, and fat percentage

If some hipsters are obsessing over it, you can assume it's probably healthy.
