Good and bad carbohydrates

Carbohydrates are present as the main source of energy in our diet. They are the sugars, starches and fibre found in fruits, vegetables, grains and milk products. Carbohydrates are often classified as simple or complex on the basis of their chemical makeup and the way the body uses them for energy.

Simple carbohydrates are the basic sugars that are readily available to the body and are easy to digest.They are found naturally in milk and fruits and refined or processed sugars added in baking , soft drinks and candies.

Complex carbohydrates are the carbohydrates which are found in whole grains, starchy vegetables, fruits, pulses and legumes . They require a series of chemical reactions to be digested and absorbed by the body.

Fibre on the other hand is not digested by the body but are essential carbohydrates as it gives the feeling of fullness, aids in digestion by regulating bowel movement and provides body with bacteria that helps to lower bad cholesterol in blood.

The daily carbohydrates intake should be 45-65% of your total calories. 1 gram of carbohydrates provides 4 kcal of energy.

  • Helps in breaking up of fats.
  • Provides with fibre which helps in digestion and regulation of bowel movement.
  • It is the instant source of energy for the body.

Glycemic index

Glycemic index is general classification of carbohydrates in accordance with how they affect blood sugar levels.

Good and bad carbohydrates

Some carbohydrates are good for health while others can lead to poor nutrition , obesity and tooth decay , so the choice of carbohydrates is very important in order to get maximum benefits from it. For example A can of soft drink provides you with almost 140-160 kcal of only simple sugar and two slice of whole grain bread or one small chapatti provides you with same number of calories along with feeling of fullness, fibre, vitamin B, and minerals. For this reason carbohydrates are generally classified as good and bad carbohydrates.

Good carbohydrates are mostly the complex carbohydrates and are high in fibre it takes time to breakdown into glucose. It is essential to get most of your calories of carbohydrates from these carbohydrates.

Bad carbohydrates on the other hand are quickly converted into glucose and causes blood sugar to rise. It is usually best to avoid these carbohydrates as much as possible and use them occasionally as a treat.

Tips to evaluate good and bad carbohydrates

Good carbohydrates

  • Are low or moderate in simple sugars
  • Rich in fibre
  • Low in saturated fats
  • Low in sodium
  • Low in refined sugar and grains

Bad carbohydrates

  • Are high in calories and refined sugars
  • Low in fibre
  • High in refined grains

  • High in sodium

Examples of good carbohydrates

  • Fruits and vegetables are good source of carbohydrates and are packed with vitamins and minerals. It is essential to add up to 5 servings of fruits and vegetables in your daily diet.

  • Whole grain cereals such as whole wheat chapatti, bread, oatmeals, corns are rich in fibre,vitamins and minerals. They have low glycemic index which helps to keep blood sugar level normal.
  • Unsweetened dairy provides you with lactose the sole carbohydrate source from animals.

Examples of bad carbohydrates

  • Fruits high in sugar such as candies, soft drinks, sweetened dairy, ice creams and desserts.
  • Refined grains such as white rice and breads because during processing the outer layer which is composed of fibre and Vitamin B is removed . Also they have high glycemic index which results in rise in blood sugar levels.
  • Commercially processed food in which sugar and refined carbohydrates are used such as pastries, cakes, patties e.t.c

Conclusion

Carbohydrates are essential part of heathy diet. A proper choice is necessary. Focus on fresh fruits , vegetables and whole grains and avoid desserts , sugars , soft drinks, and processed food foods rich in sugars

Pulses

pulses are the dry and edible seeds of the legumes with low fat content. They are widely used by humans and animals all around the world. Most common examples of pulses are chickpeas, dried and split peas, kidney beans, soya beans, mung beans, and several types of lentils.

Nutritional composition of pulses

Pulses are rich in proteins almost twice the amount of proteins found in wheat. They are rich in carbohydrates , fibre, minerals like iron, calcium, phosphorus and vitamin B12. In many countries, where meat prices are high or meat consumption is forbidden due to religious factors, pulses are often used as a meat substitute because of its high protein and iron content.

Health benefits of pulses

  • Pulses are good for weight management. Becauseof the high satiety effect of fibre and proteins present in pulses, it gives the feeling of fullness for a longer period of time. Also because of the low glycemic index and fat content, pulses are good for people with diabetes.
  • The high fibre content of pulses helps to lower ldl cholesterol and reduces the risk of heartdiseases.
  • Pulses are rich in non heme iron. Iron in pulses if used with food containing vitamin C is readily absorbed by the body and prevent iron deficiency anaemia in women and children.
  • Pulses are rich in antioxidants and phytochemical that may contains anti cancer properties.
  • Pulses are rich in folic acid which reduces the risk of neural tube defects in newborns.

Cooking techniques

  • Soaking of pulses for 4-8 hours reduce their phytate content and cooking time. Soaking also helps to prevent flatulence and bloating which are normally caused by pulses. Pulses also contain some anti nutrients that reduce the ability of body to absorb nutrients present in them. These anti nutrients are removed by prolonged soaking of pulses with sodium bicarbonate.
  • Pulses should be used with the source of vitamin C as it helps to absorb the iron present in them. Lemon juice on top of chickpeas salad is a perfect example.
  • Pulses can be combined with variety of foods such as meat, grains and vegetables. They can be uses as a salad, main course or in soups and pastas.

It is widely consumed by people around the world and sometimes replaces water. These carbonated beverages are alcohol free but according to some studies a small amount of alcohol may produce as a result of fermentation of sugars and by adding flavouring extracts.

health risks associated with excessive consumption of soft drinks

The potential risks associated with the excessive consumption of soft drinks include

Obesity

Carbonated beverages and fruit drinks provide you with empty calories which contributes to weight gain and obesity. A can of 330 ml of carbonated soft drink provides you with 140 kcal . It means that one person is consuming almost 7 tsp of sugar in one go. The low levels of satiety provided by these soft drinks makes people consume more food along with the drinks which results in weight gain. Sometimes these commercially available soft drinks contains high fructose corn syrup as a sweetener which is comparatively cheaper than common sugar, it stimulates appetite and is responsible for metabolic disorders including type 2 diabetes, hypertension and heart diseases

Bone loss

Excessive consumption of soft drinks can result in bone loss and reduction in bone mineral density. This is because people who consume more soft drinks do not consume much milk which results in the diet deficient in vitamin b12 , b6 and calcium . Also the phosphoric acid present in colas displaces calcium from the bones which results in lowering bone density , bone loss and ultimately osteoporosis.

Tooth decay

The acid such as carbonic and phosphoric acid present in soft drinks erodes teeth enamel and high sugar content of these drinks make teeth more susceptible to decay. Studies reveal that those who consume these soft drinks on regular basis are at higher risk of developing dental carriers and tooth decay than those who tend to avoid it.

Cancer

The chemical process used for caramelisation in cola drinks produces the carcinogen which increases the risk of cancers . Studies suggest that high consumption of soft drinks doubles the risk of developing pancreatic cancer , prostrate cancer in men and breast cancer in young girls.

Tips to avoid soft drinks

Some basic tips and tricks to avoid soft drinks are

  • Replace soft drinks with homemade fruits and vegetables juices with less sugar
  • Drink a glass of water if you are having a desire of soft drink. A glass of lemonade with little slat and sugar is a healthy substitute.
