A person who does not eat animal products and plants is known as a "fruitarian." Fruitarianism is a dietary practice that involves consuming only fruits, nuts, seeds, and other plant-based foods that can be harvested without harming the plant. Fruitarians avoid animal products and plant parts such as roots, leaves, and stems, as they believe it may harm the plant or the organism. It's essential to note that fruitarianism is a very restrictive diet and may not provide all the necessary nutrients for a balanced and healthy lifestyle. As with any restrictive diet, it's essential to consult with a healthcare professional or a registered dietitian to ensure that nutritional needs are adequately met.
