Foodie Sims tend to receive happymoodlets from eating high quality food and drinks; but get uncomfortable after eating or drinking something of normal / poor / spoiled quality. For example, the "Sleep Replacement" potion results in "Smooth Sipping" for non-Foodie Sims, but gives the "Disappointing Drink" moodlet to Foodie Sims.
By "Watching Cooking Shows for Ideas", Foodie Sims get the "Inspired to Cook" moodlet which helps in their culinary pursuits.
They might get an uncomfortable "Terrible Food" moodlet when they ate poorly-made-food.
They are more likely to spontaneously choose to watch the Cooking Channel on TV.
