Eating a swordfish has a delay of 1. Eating a lobster has a delay of 1. Eating half of anchovy pizza has a delay of 0,5. Any pizza - 0,5. Any pie - 0,5. Cake - 1. Most of other common food like fish and potatoes have 1. The tip 1. in the quote is true, the tip 2. isn't as half of anchovy + swordfish = 1,5 delays. However a tip by me - meat pizza can be really good food in f2p - much cheaper than anchovy and heals only 1 hp per bite less. As you can heal 16hp in one delay, they can be better than swordfish in some situations.
