Popular Cereals and Their Nutritional Benefits

Cereals, being integral to diets worldwide, come in various types, each with unique characteristics and nutritional benefits. Here are some popular cereal types:

1. Wheat:

   • Uses: Bread, pasta, pastries, and many other baked goods.
   • Nutritional Benefits: High in carbohydrates, provides fiber, protein, and several B vitamins.
   • Varieties: Includes common wheat (used for bread), durum wheat (used for pasta), and spelt.

2. Rice:

   • Uses: Staple food in many cultures, used in dishes like sushi, risotto, and pilaf.
   • Nutritional Benefits: Good source of energy, provides vitamins such as B1 (thiamine) and minerals.
   • Varieties: Includes white rice, brown rice, basmati, jasmine, and arborio.

3. Corn (Maize):

   • Uses: Consumed as cornmeal, polenta, popcorn, and in tortillas and cornbread.
   • Nutritional Benefits: Rich in carbohydrates, vitamins like B3 (niacin), and minerals such as magnesium.
   • Varieties: Includes sweet corn, dent corn, and flint corn.

4. Oats:

   • Uses: Breakfast cereals, granola, oatmeal, and in baked goods.
   • Nutritional Benefits: High in soluble fiber, especially beta-glucan, which helps lower cholesterol. Also provides protein and iron.
   • Varieties: Includes rolled oats, steel-cut oats, and instant oats.

5. Barley:

   • Uses: Soups, stews, bread, and malt for beer production.
   • Nutritional Benefits: Rich in fiber, vitamins like B6, and minerals such as selenium and magnesium.
   • Varieties: Includes hulled barley, pearled barley, and barley flakes.

6. Rye:

   • Uses: Bread (such as pumpernickel and rye bread), crispbreads, and whiskey.
   • Nutritional Benefits: Good source of fiber, protein, and minerals such as manganese and phosphorus.
   • Varieties: Includes winter rye and spring rye.

7. Sorghum:

   • Uses: Porridge, unleavened bread, and as a gluten-free flour alternative.
   • Nutritional Benefits: High in protein, fiber, and antioxidants. Gluten-free.
   • Varieties: Includes grain sorghum, sweet sorghum, and broomcorn.

8. Millet:

   • Uses: Porridge, flatbreads, and as bird feed.
   • Nutritional Benefits: Rich in fiber, magnesium, and B vitamins. Gluten-free.
   • Varieties: Includes pearl millet, finger millet, and foxtail millet.

These cereals play crucial roles in diets across the globe, providing essential nutrients and forming the backbone of many traditional and modern dishes.

Organic Cereals

Organic Cereals
Some people in first-world countries now believe that modern practices have become so destructive of the environment and of the health and welfare of the populace.

It is argued that agrochemicals have polluted the environment and damaged the local ecology: this is highly debatable because far less land is needed for staple food production under modern intensive systems than organic systems, which are labor intensive and give low yields.

It is also argued that the crops produced by modern farming methods are “inferior” to those harvested by our forefathers.

It is claimed that they taste inferior, have different textures, and poorer nutritional value.

Pliny, writing in Ancient Rome, said much the same: country bread was nicer and much more wholesome than the white bread eaten by city people.

Crops from farms using agrochemicals can also contain residual amounts of pesticides and other chemicals.

These chemicals will be a small part of the human diet. For these reasons alternative “organic farming practice” are being encouraged or at least experimented with in regions where food is in surplus.

Organic farming is becoming well established in the United States. In 1996 more than 7000 organic farms were recognized by the government.

Farmers following “organic” farming practices replace chemical fertilizers, pesticides and other agrochemicals with organic material such as composted vegetarian and manure from farm animals.

Crop rotation with the use of nitrogen-fixing plants such as clover increase the nitrogen levels in soil.

Weeds are discouraged by hoeing, mulching (covering with manure, straw, or sacking, burning) or removing by hand, which is expensive.

Pests are controlled by a variety of methods.

Organic farmers may also design shelters that physically protect their crops from weeds and pests.

Organic farming is more labor intensive and therefore the products are more expensive; however, the defenders of organic practices argue that as less non-sustainable fossil fuel is needed and other “hidden” advantages such as better soil structure, less soil erosion and more diverse ecology are achieved, the price is worth paying.

However for the foreseeable future only a rich population can afford to pay for a luxury of organic staple foods should they wish to.

The Importance of Cereals in Human Nutrition

The Importance of Cereals in Human Nutrition
In almost every country and region, cereals provide the staple food. In the world as a whole, only 5% of starchy staple food comes from root crops (mainly cassava, potato, and yams, depending on climate), whereas the rest is from cereal. There is a greater dependence in roots in the developing economies, where the average figure for roots is 10%.

Cereal grains contain 60% to 70% starch and are excellent energy rich foods for humans. Doctors recommend cereals as the first food to be added to infant diets and evidence from research upholds that healthy diet for adults should have most of its calories in the form of complex carbohydrate such as cereal starch. Even in countries, such as United Kingdom, where there is a wide choice of different foods available, people gets a large amount of their dietary energy (20% - 30%) from cereals or foods containing cereal starch.

A healthy human diet must also include 20 to 30 g/day of dietary fiber, which can easily achieved by eating whole grain cereal products such as breads, cookies or porridges.

Adult woman requires about 50 g of protein per day, whereas an adult man needs slightly more (about 63g). The cereals can easily supply this quantity of protein, but unfortunately they lack the essential amino acid lysine and therefore they must not be used as the sole source of dietary protein. In rural areas of poorer countries people may eat more than 500 g of cereal per day, which will provide most of their protein needs (and more than 50% of their total daily energy requirement).

Cereals are an excellent source of fat soluble vitamin E, which is an essential antioxidant. Whole cereal grains contain 20% to 30% of the daily requirements of the minerals selenium, calcium, zinc, and copper.

Unfortunately, bran contains substances such as phytic acid, which chelates minerals, preventing them from being easily digested and absorbed. It is therefore important that grain is processed correctly so that optimum nutrition benefits can be achieved.
