Some facts about grains

Written by Paris kazemian
Grains are a type of edible cereal crop that are harvested for their seeds. Common grains include wheat, rice, corn, oats, barley, and rye. These grains are a staple food source for many cultures around the world and are used in a variety of ways, including as a base for flour, bread, cereals, pasta, and other foods. Grains are typically high in carbohydrates and provide energy for the body. They also contain varying amounts of other nutrients such as protein, fibre, vitamins, and minerals.

Different types of grains

Grains are classified into two groups:

1. Whole grains: These are grains that contain the entire grain kernel, including the bran, germ, and endosperm. Examples of whole grains include whole wheat, brown rice, quinoa, and oats. Whole grains are a good source of fibre, vitamins, minerals, and other important nutrients.
2. Refined grains: These are grains that have had the bran and germ removed, leaving only the starchy endosperm. Examples of refined grains include white flour, white rice, and many types of bread and pasta. Refined grains are often lower in fibre and nutrients than whole grains.

It is recommended that at least half of the grains you consume be whole grains. You can choose whole grain breads, cereals, pasta, and rice to increase your intake of whole grains. The recommended daily intake of grains varies depending on age, sex, and level of physical activity.

Why are grains important?

Refined grains are grains that have had the bran and germ removed, leaving only the starchy endosperm. While refined grains can be a part of a healthy diet, they are generally considered to be less nutritious than whole grains because they are lower in fibre, vitamins, minerals, and other important nutrients.

However, refined grains do have a few benefits. They tend to be easier to digest than whole grains, which can be helpful for people with digestive issues or those who are recovering from an illness. Refined grains can also be a good source of energy, as they are a quick and easily digestible source of carbohydrates.

It’s important to note that many refined grain products, such as white bread and white rice, are often highly processed and contain added sugars and fats, which can contribute to weight gain and other health problems. Therefore, it’s important to consume refined grains in moderation and to choose whole grain products whenever possible to ensure a more balanced and nutrient-dense diet.

Whole grains provide a range of health benefits, including:

• Improved heart health: Eating whole grains is associated with a lower risk of heart disease, stroke, and high blood pressure. Whole grains contain fibre, antioxidants, and other compounds that can help reduce inflammation, improve cholesterol levels, and lower blood pressure.
• Better digestion: Whole grains are a good source of dietary fibre, which can help promote regularity and prevent constipation.
• Reduced risk of certain cancers: Studies have found that eating whole grains may help reduce the risk of certain types of cancer, including colorectal, stomach, and pancreatic cancer.
• Weight management: Whole grains can help you feel full and satisfied, which may help you consume fewer calories overall and maintain a healthy weight.
• Improved blood sugar control: Whole grains have a lower glycaemic index than refined grains, which means they can help regulate blood sugar levels and reduce the risk of type 2 diabetes.
  
  Overall, incorporating whole grains into your diet can provide a range of health benefits and contribute to a balanced and nutritious diet.

Grain protein differs from other types of protein!

The protein found in grains is different from the protein found in meat and dairy. While all proteins are made up of building blocks called amino acids, the specific types and proportions of amino acids vary between different sources of protein.

Meat and dairy products are considered “complete” sources of protein, as they contain all of the essential amino acids that the human body needs to build and repair tissue. In contrast, most grains are considered “incomplete” sources of protein because they do not contain all of the essential amino acids. However, by combining different types of grains or combining grains with other plant-based sources of protein, it is possible to create a complete protein source.

It’s also worth noting that grains and other plant-based sources of protein tend to be lower in fat and cholesterol compared to meat and dairy products. Additionally, some studies suggest that diets high in plant-based protein may have certain health benefits, such as a lower risk of heart disease and type 2 diabetes.

Negative aspects of grain

While grains can be a nutritious and important part of a healthy diet, there are some potential disadvantages to consider as well. These can include:

1. High in carbohydrates: Grains are typically high in carbohydrates, which can be a disadvantage for some people who are trying to manage their blood sugar levels, such as those with diabetes.
2. Gluten intolerance: Some people may have a gluten intolerance or sensitivity, which can cause digestive issues when consuming grains that contain gluten, such as wheat, barley, and rye.
3. Phytic acid content: Grains contain a substance called phytic acid, which can bind to minerals such as calcium, iron, and zinc, making them less available for absorption by the body. This can be a concern for individuals who rely heavily on grains as a primary source of nutrition.
4. Pesticide residues: Grains, like many other crops, may contain pesticide residues that could potentially have negative effects on human health. Choosing organic grains can help reduce exposure to these residues.
5. Processing and refining: Many grain products, such as white bread and refined cereals, are heavily processed and stripped of important nutrients such as fiber, vitamins, and minerals. Choosing whole grain products can help mitigate this issue.

Those who need to stay away from grains!

Most people can safely consume grains as part of a balanced and healthy diet. However, there are some groups of people who may need to limit or avoid grains due to certain health conditions or dietary restrictions. These include:

1. People with celiac disease: Celiac disease is an autoimmune disorder in which the consumption of gluten, a protein found in wheat, barley, and rye, can trigger an immune response and damage the lining of the small intestine. People with celiac disease must avoid all sources of gluten, including most grains.
2. People with non-celiac gluten sensitivity: Some people may experience digestive symptoms when consuming gluten, even if they do not have celiac disease. These individuals may need to limit or avoid grains that contain gluten.
3. People with grain allergies: Some individuals may have an allergic reaction to specific grains, such as wheat, corn, or rice. In these cases, it’s important to avoid the specific grain that triggers the allergic reaction.
4. People following a low-carbohydrate or ketogenic diet: Some diets, such as the ketogenic diet, require very low carbohydrate intake. In these cases, grains may need to be limited or avoided.
5. People with other dietary restrictions: Some individuals may choose to avoid grains for personal or religious reasons, such as those following a paleo or kosher diet.

If you are unsure whether or not you should be consuming grains as part of your diet, it’s always a good idea to speak with your dietitian for personalized advice.
