Nutritional illustrations are a useful tool for anyone interested in learning or teaching about nutritional foods. These health education posters highlight necessary vitamins, minerals, and food groups that promote a healthy body. Works such as 'Vitamins' take advantage of the illustrative qualities of these posters to relay what foods provide necessary vitamins. However, the most common form of these nutritional posters is the nutritional pyramid, which shows the different food groups.
Many health education posters serve as either motivational tools or as warnings against negative behaviors. These health visual aids are more effective than print alone and can reveal information through images that wouldn't be immediately apparent otherwise. For example, in the health education image, 'Your Brain' warns of the dangers of drugs, even ones that might seem relatively harmless.
