Please learn your facts before you post an article that many people can see.
1. Glucose is not bad for humans. EVERY cell in the human body runs on glucose!! Not fat or protein. (not saying these two macronutrients aren't important) Carbs are the healthiest foods you can eat...but LOW FAT carbs. Sources: fruit is #1, then cooked carbs such as potatoes, rice, and other root vegetables.
2. Rice and potatoes are great for you as long as you keep them low fat and vegan
3. Salads are VERY HEALTHY. Given you don't add tons of fatty dressing full of animal biproducts. You say lettuce isn't even that healthy and it has a low amount of vitamins. Leafy greens are INCREDIBLY healthy for humans. They contain an abundance of vitamins, minerals, and amino acids that are very healthy for us. They should be eaten every day without restriction. Good salad dressing recipe: orange juice, dill, and ginger. Or mangoes and cilantro blended. YUMMM! :)
4. Oil and vinegar are TERRIBLE for you, against the common belief. Oils are 100% refined fat. All they do is add junk to the trunk. Looking for healthy fat? Try a half of an avocado in a salad or a glass of coconut milk. Vinegar is extremely acidic and not healthy at all. It is just an unnecessary processed acidic food that should be avoided.
Make your own salad dressing people!
Blend:
orange juice, dill, and ginger
dates and orange juice
mangoes and cilantro
Experiment with fresh fruit and herbs!! :)
