Mixture is a combination of tow or more different substances
Pure substance is one type substance, throughout and uniforn proporties

Most rocks are mixtures of two or more minerals. Minerals are naturally occurring inorganic substances that have a specific chemical composition and crystal structure. Rocks are formed from a combination of minerals through geological processes like cooling and solidification of molten materials.
The most general classification of matter is into elements, compounds, and mixtures. Elements are composed of only one type of atom, while compounds are composed of two or more different types of atoms chemically bonded together. Mixtures are combinations of two or more substances that are physically mixed together but not chemically bonded.
Most naturally occurring materials are not pure substances as they often contain mixtures of different compounds or elements. For example, minerals, rocks, and soils are composed of various elements and compounds, making them impure. Pure substances are rare in nature and are typically only found in the form of elements (like gold or silver) or compounds with a specific chemical composition (like water or salt crystals).
Some kinds of fibre are elements, such as carbon fibre and silicon "whiskers"; some are compounds or near compounds, such as cellulose or polypropylene; but most are mixtures, such as wood fibres, which contain both cellulose and lignin.

Most foods, as they occur in nature, are already a compounded materials. The carrot for example is a combination of carbohydrates, sugar, fiber, beta-carotene, etc. Each of those is a group of molecules that are in turn made of several different atoms. There is no logical reason to make a food that is simply a block of protein with no fat or carbohydrates since the human body cannot survive on any one material alone. That is why any doctor will tell you that a well rounded diet is important.
No. Any sugary foods and/or beverages are most definitely NOT a good way to lose weight.
Caffeine is the most widely used psychotropic drug in the world. It is found in coffee, tea, and many other beverages and foods.

Matzoh, meat, fish, vegetables, fruit, eggs, dairy products, most kinds of nuts, and most beverages. All beverages, meats and processed foods need to be labeled Kosher for Passover, with trustworthy supervision and not containing Kitniyos (legumes). Today there are thousands of canned and processed foods which have strict Passover supervision. Several decades ago, the answer would have been: buy veggies and prepare them yourself.
In the absence of the gas oxygen, certain living things are capable of breaking down carbohydrates (starches and sugars) to form alcohol and carbon dioxide gas. This process is known as anaerobic respiration or fermentation, and it has been used for centuries in the production of certain foods and beverages.
Food is anything that is eaten. An ingredient is a constiuent, or part, of a specific food or recipe for food. Most foods are mixtures of ingredients. Ingredients are combined, or prepared, using a recipe, which is a guide to preparing a certain food or combination of foods.

No, elements are the most basic form of a substance, thus mixtures might be made up from different elents but elements can never be made from mixtures.
