What You'll Learn
Whole grains are linked to numerous health benefits
Whole grains contain the entire grain kernel, which includes the bran, germ, and endosperm. This composition sets them apart from refined grains, which have been milled to remove the bran and germ, resulting in a loss of dietary fibre, iron, and B vitamins. By contrast, whole grains retain these essential nutrients, making them a more nutritious option.
The bran layer of whole grains, such as brown rice, is particularly noteworthy for its biofunctional and nutritional compounds. It is a good source of fibre, which has been shown to lower blood cholesterol levels and reduce the risk of cardiovascular disease. Additionally, the germ of whole grains is a nutrient-dense core containing carbohydrates, fats, proteins, vitamins, minerals, antioxidants, and various phytonutrients.
The health benefits of whole grains extend beyond their nutritional content. They are also a good source of energy, providing 10,000-15,000 kJ/Kg, which is significantly higher than the energy provided by fruits and vegetables. This makes whole grains a vital component of a balanced diet, especially for those who are physically active or have higher energy requirements.
It is worth noting that some individuals may have concerns about antinutrients present in whole grains, such as phytic acid and lectins, which can interfere with the absorption of certain nutrients. However, these antinutrients are not unique to grains and can be found in many other healthy foods. Additionally, preparation methods like soaking, sprouting, or fermenting grains can help degrade these antinutrients, minimising any potential negative effects on nutrient absorption.

They are a good source of dietary fibre
Cereal grains are an important source of dietary fibre. The bran, or outer layer of the grain, contains fibre, minerals, and antioxidants. The germ, or nutrient-rich core, contains fibre, as well as carbohydrates, fats, proteins, vitamins, minerals, antioxidants, and various phytonutrients.
When grains are refined, the bran and germ layers are often removed, resulting in a significant loss of fibre, vitamins, minerals, antioxidants, and phytochemicals. While some fibre, vitamins, and minerals may be added back into refined cereal products, it is impossible to fully replicate the original mix of nutrients.
Whole grains, on the other hand, retain their fibre content and provide numerous health benefits. Fibre from whole grains can help to reduce blood cholesterol levels, support healthy digestion, and lower the risk of heart disease. It is also important for proper bowel function.
In addition to their fibre content, whole grains are a good source of dietary protein, phytocompounds, minerals, and vitamins. They have been linked to a reduced risk of several chronic conditions, including type 2 diabetes, cardiovascular diseases, and certain types of cancer.
Overall, cereal grains are an important source of dietary fibre, and the consumption of whole grains in particular is associated with a range of positive health outcomes.

Cereal grains are easy to store and transport
Cereal grains are a staple food in most countries and are a part of many people's breakfasts. They are a significant source of food worldwide, with 60% of calories and protein consumed provided by cereals. Cereal grains are easy to store and transport, and they have a long shelf life.
Cereal grains are small, hard, and edible dry seeds that grow on grass-like plants called cereals. They are easy to carry, package, and transport from one place to another. Cereal grains have a low moisture content, which means they can be stored for long periods without affecting their nutritional value. This makes them a stable food source that can be relied upon even in areas with harsh environmental conditions.
The ease of storage and transportation of cereal grains contributes to their widespread consumption and makes them a convenient and accessible food option for people around the world. Cereal grains are also versatile and can be used as an ingredient in various products, such as porridge, breakfast cereals, bread, cereal-based beverages, and baked goods.
Additionally, cereal grains are a good source of nutrients, including dietary fibre, complex carbohydrates, proteins, vitamins, and minerals. They contribute to a healthy diet and have been linked to reducing the risk of chronic conditions such as cancers, type 2 diabetes, and cardiovascular diseases.
However, it is important to note that the health benefits of cereal grains are primarily associated with whole grains rather than refined grains. Refined grains undergo a milling process that removes the bran and germ, resulting in the loss of dietary fibre, iron, and B vitamins. Therefore, when consuming cereal grains, it is generally recommended to choose whole grains or enriched refined grains to ensure optimal nutritional value.
