of the choices: proteins starches nucleotides lipids nucleotides are not macromolecules
Foods contain proteins, carbohydrates and lipids which are three different types of macromolecules. However, there are far more than three types of macromolecules, some of which are also found in food.
"Biomolecules" is not a recognized term in biochemistry, rather a term such as organic molecules or macromolecules would be more appropriate. The simple answer is all foods have complex organic macromolecules such as lipids (fat), carbohydrates/sugars and protein in varying quantities and types.
All macromolecules contain a monomer.
Proteins and nucleic acids

Foods contain proteins, carbohydrates and lipids which are three different types of macromolecules. However, there are far more than three types of macromolecules, some of which are also found in food.
Proteins and nucleic acids are organic macromolecules that contain nitrogen.
All foods contain nutrition, but the type of nutrients depends on the type of food, for example meats contain proteins.
Energy in all foods comes from calories, which are in starches, fats and proteins. Peanuts contain a high percentage of fat, which is the source of most of their calories, or energy.
Calories are a measure of heat energy. Eating foods that contain calories allows your body to expend energy and to maintain body temperature. Excess calories are stored as fat.
They are called "empty" calories because they contain little to no nutritional value at all.
There are very few foods that have no nutrients whatsoever, but still have calories. More foods would fall into the range that they contain calories, but very little nutrients. These are known as "empty calories", meaning that they really do not help for the body. Some examples of these would be fried foods, refined sugars / starches, bleanced flours, and high-fat foods (like butter and lard).
Foods that do not follow nutrient density and contain less nutrients that calories. Ex. chocolate ice cream cookies cake
Hamburger
Energy-dense foods tend to be processed foods with sugar and fat added to improve the taste. The result is more calories per ounce
Proteins and nucleic acids
