Vegan diets tend to be higher in dietary fiber, magnesium, folic acid, vitamin C, vitamin E, iron, and phytochemicals, and lower in dietary energy, saturated fat, cholesterol, omega-3 fatty acid, vitamin D, calcium, zinc, and vitamin B12. As a result of the elimination of all animal products, a poorly planned vegan diet can lead to nutritional deficiencies that counteract its beneficial effects and cause serious health issues, some of which can only be prevented with fortified foods or dietary supplements. Vitamin B12 supplementation is important because its deficiency can cause blood disorders and potentially irreversible neurological damage; this danger is also one of the most common in poorly planned non-vegan diets.[

cookie (American English) or biscuit (British English) is a baked snack or dessert that is typically small, flat, and sweet. It usually contains flour, sugar, egg, and some type of oil, fat, or butter. It may include other ingredients such as raisins, oats, chocolate chips, or nuts.

Chocolate brownie, or simply a brownie, is a chocolate baked confection. Brownies come in a variety of forms and may be either fudgy or cakey, depending on their density. Brownies often, but not always, have a glossy "skin" on their upper crust referred to as flint. They may also include nuts, frosting, chocolate chips, or other ingredients. A variation made with brown sugar and vanilla rather than chocolate in the batter is called a blond brownie or blondie. The brownie was developed in the United States at the end of the 19th century and popularized there during the first half of the 20th century.
