Meats (tallow, chicken fat, goose fat, duck fat, or others). Raw dairy products (butter, cream, whole milk or full-fat cheese or yogurts). Sardines (some others such as salmon, tuna and others have some quality fats, but are too high in mercury to be healthful foods).
Pimples in the nose are not usually the same as those on other parts of the surface of the skin. It is usually as a result of folliculitis which is caused by infection of hair follicles in the nostrils. Mostly it is as a result of bacterial imbalances which could be triggered by a number of factors.
Treatment for a pimple inside the nose depends on its cause. Traditional acne pimples will likely go away with at-home care and time. A bacterial infection is commonly treated with antibiotics. This includes the application of antibiotic ointments, such as bacitracin or mupirocin.
