Stop counting calories, fat, protein, carbs & sodium. If you are then you’re worrying about the wrong part of the label. First check the ingredients. Will the body recognize it as food. Will it be digested and assimilated or will it take time and energy for the body to figure out what it is and what to do with it. Keep in mind that water is the key to life and vitality. Our bodies are more than 75% water. Therefore if the foods that we eat are water based and water soluble they are assimilated, digested and easily broken down by our bodies.
Yes meat has more protein than veggies but because of  the time and energy it takes the body to glean the good nutrients from the dense dead matter it becomes negligible and dehydrating. Grains may be rich in carbs but are also dry and dense. The body processes them by converting them directly into sugar in the bloodstream. They actually effect the body in exactly the same way as alcohol. You get the carb high then you crash. At what loss of vitality health and longevity is all this difficult processing?
Raw greens may have less protein and carbs than meat or grains but they are water-filled and break down immediately and go straight into the blood  with no trouble or loss of energy. In fact they create immediate energy  not just a stimulation with a crash later. Meat and grains actually act as a stimulant or poison in the system.
When I check labels of processed foods I do look at fat calories but first I read what fats are there and what else is actually in it. Do I recognize the ingredients as food? Oils are a huge red flag for me. Our bodies do not digest cooked oils and practically all processed foods have been cooked or pasteurized. The only  digestible fats are raw plant based fats. If you see cold or expeller pressed oils on a label of a processed food ask yourself this: is this food cooked? If so what good is a cold pressed oil? It has been heated now right? Heated oils are rancid and poisonous to the body. I will occasionally eat a food with a small amount of oil in it, like certain marinaras. But I try to always eat them with plenty of vegetables.
The body needs fat but the only fats we really assimilate for lubrication of joints, eyes etc are raw plant based fats like avocado or cold pressed olive or coconut oil. Raw nuts and seeds are also digestible fats but they are so dense and  dry that they are dehydrating and difficult to digest so their benefits are negligible in an acidic compromised system. They can also be damaging if too many are eaten at a time. All other fats are stored in the body as fat.
Also in the ingredients list on labels I look for grains. Wheat flour, rice or rice flour, soy or soy flour are gluey and pasty. They are also so dry that they need a lot of energy to digest. They have a stimulating effect because they convert to sugar in the bloodstream. Athletes carb up and get temporary energy but at what cost. Foods that are carb and nutrient rich and still easy to digest are sweet potatoes and other root vegetables.
I also look for dairy products. Cow dairy is extremely indigestible for humans and it is sticky and gluey. You might have trouble wrapping your mind around this but cream and butter are easier to digest than milk, cheese or even yogurt. Cream and butter don’t contain the protein casein which is the indigestible protein in cows milk.
Greasy foods like cooked oils and fatty meats leave residue. Sticky pasty gluey foods like flour and dairy products leave residue. These residues can remain and build up in the tissues our entire lifetime. If we eat these foods we need to eat them with intelligence knowing that we need to help the digestion along with plenty of raw roughage like fresh green salads that will help shepherd the dehydrated and dehydrating foods through our long alimentary tract while basically rinsing and scrubbing at the same time. Then before we eat anything else sticky or gluey we need to drink plenty of fresh pressed green juice that will help rinse out the alimentary tract and flood the body with enough alkalinity to counter balance the acidity of these questionable foods.
Think about it
Foods that move through the body quickly and cleanly and are water-rich and nutrient-filled are the foods that contribute to abundant health and energy.
The best foods for our bodies don’t even have labels or lists of ingredients. You’ll find them in the produce department.
