The whole point of a balanced diet is literally in the name. Food should be balanced. That’s it. That’s the main and almost the only principle. For me, a balanced diet is when you can eat basically everything, just in reasonable amounts. Also, it makes sense to keep an eye on how much fat, protein and carbs you’re getting, but I think without going overboard. Just keep in mind that the foods you pick contain enough of those nutrients. Right now a lot of people are into veganism or vegetarianism, but for me balance in nutrition is not possible without meat, and here I want to point out the quality of the products you choose. You can buy meat here

Meat you can buy in an online store with delivery is good quality, because the animals are free range, eat 100% grass with no antibiotics and hormones.
