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.
There are multiple skin diseases that can cause thickness of the nose including infectious, neoplastic and connective tissue disorders but the most common is Acne and Rosacea. In Acne/Rosacea, the sebaceous glands (oil glands) may enlarge and give the appearance of a bulbous nose. Additionally, acne cysts and pimples can produce swelling that may produce a larger appearance to the nose.
