Absolutely terrible way to compare foods. The fact that many veg proteins are incomplete means they only have some of the amino acids we need, and must be paired with other foods to get a complete set. Generally that's "rice and beans" kinda combos. Though some plants have complete proteins
Also there are obvious downsides to many of the foods on the right side, like high cholesterol/saturated fats that will kill you from heart disease, and red meat being linked to diabetes/cancer
