Nutrition and Food Sources

Carbohydrates, fats, and proteins are the three macronutrients that provide the body with energy measured in calories.

Fortification is the process of adding micronutrients (essential trace elements and vitamins) to food to improve its nutritional quality.

Apples, blackcurrants, and gooseberries are naturally high in pectin, which is why they are commonly used in jam making to help the mixture set.

High-risk foods are those that support the growth of bacteria and are usually eaten without further cooking. A tin of beans is shelf-stable and processed to be sterile, making it low-risk until opened.

Pollen grains are highly nutritious and are marketed as food supplements to improve performance in athletes and racehorses.

Corn, rice, and wheat are the three most widely consumed staple crops globally, providing the majority of calories for the human population.

Most natural fats and oils are a combination of different types of fatty acids, rather than being composed of only one type.

Diets rich in plant-based foods provide fiber, antioxidants, and phytochemicals that are associated with a lower risk of various cancers.

Public health organizations, including the World Health Organization and the American Institute for Cancer Research, estimate that approximately one third of all cancer cases are linked to dietary factors, weight, and physical activity. Therefore, the statement is accurate.

A balanced diet requires a variety of macronutrients (carbs, fats, proteins) and micronutrients (vitamins, minerals) along with adequate hydration.

Meat, dairy, fish, and legumes are primary dietary sources of protein. These foods are rich in the amino acids necessary for building body tissues.

Globally, the majority of human caloric intake is derived from cereal grains, specifically wheat, rice, and corn (maize).

Due to the widespread use of corn and soy derivatives in food processing, it is estimated that a large majority of processed foods in the U.S. contain GMO ingredients.

Wheat and rice are the two most widely consumed staple crops globally, providing the majority of caloric intake for the human population. Other combinations do not account for as high a percentage of global caloric consumption.

In developed countries, higher income levels allow for a diet that includes a significant amount of meat as a primary source of protein, unlike in developing countries where grains are the main source.
