The seeds of grasses that are grown for food, or grains, are essential to agriculture and world cuisines. They are separated into two categories: pseudo-cereals (such as buckwheat and quinoa) and cereals (such as wheat, rice, and maize).
Grains are an essential part of diets around the world because they each provide different nutritional benefits, such as carbs, proteins, vitamins and minerals. These palatable seeds or fruits of grasses in the Poaceae (sometimes referred to as Gramineae) family are called grains. Their nutrient-rich seeds are farmed for food, as they are a staple in many countries.
In addition to common grains like rye, barley and oats, lesser-known grains enhance meals with a variety of tastes and textures.
To appreciate the importance that grains play in food culture, nutrition and sustainable agriculture, one must have a thorough understanding of their variety and also know the benefits one tends to stand by in the consumption of these grains. So let’s move on.
Types of Grains
As stated earlier, we have seen that there are two types of grains we have . And in this section, we could know the types of grains and learn the different varieties of grains under this types of grains
As we all know now, “Cereals” and “pseudocereals” are the two primary kinds of grains.
- Cereals: Known types of wheat, rice, corn (maize), barley, oats, rye, sorghum, and millet are among the actual grains that fall under this category. In addition to having varied amounts of protein, fiber, vitamins and minerals, they are a significant source of carbs, which provide you with energy.
- Pseudo-cereals: Although not actual grains, these are utilized in a similar way because of their similar nutritional profiles and culinary applications. Quinoa, amaranth and buckwheat are a few examples.
CEREALS
So we are going to be discussing the various types of grains found in this category. They include
1. Wheat
