Collection of Food and Dietary Supplement Intake Data: What We Eat in India

Nutritional Deficiencies

Patients who have had bariatric surgery may have nutritional deficiencies. These include:

What are vitamin deficiencies?

If you are not absorbing enough vitamins , you may be low on the following:
  • Fat soluble vitamins, including D, K, A and E
  • Water soluble ones, including C and B (1- thiamin, 12 and folate)
 Vitamin Deficiencies
 Vitamin A
Lose of visionVisual and skin changes
 Vitamin B1 (Thiamin)

  • Thiamin (vitamin B1) is important for energy metabolism, particularly carbohydrate metabolism. It’s also key for muscle contractions and the conduction of nerve signals.
  • Thiamin deficiency causes beriberi disease and can cause weakness, fatigue, psychosis and nerve damage.Whilst it’s not very common, alcoholics are most at risk of beriberi.
 Vitamin B2 (Riboflavin)

  • Riboflavin (vitamin B2) is also involved in energy metabolism. It keeps the skin, eyes and nervous system healthy. 
  • Deficiency of riboflavin (ariboflavinosis) can cause several symptoms such as a sore throat, cheilosis (lesions on the lips), normocytic, normochromic anaemia, and angular stomatitis (lesions on the angles of the mouth). Without riboflavin, several other vitamins, such as folate, can’t be metabolised so riboflavin deficiency often occurs with other vitamin deficiencies
 Vitamin B12
 Anemia
 Vitamin C (or ascorbic acid)

  • Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur.
  • Vitamin A deficiency is the world’s leading cause of preventable blindness in children, and increases the risk of disease and death
  • In pregnant women, a deficiency can cause night blindness, and increase the risk of maternal mortality
 Vitamin D

  •  Bone abnormalities:it helps to regulate the amount of calcium and phosphate in the body; Rickets
  • A lack of vitamin D can lead to rickets in children and osteomalacia in adults, which is characterised by weakness, aches and pains because the bones don’t have enough calcium
 Vitamin E (antioxidant)

  •  Neurological problems
  • maintaining healthy skin and regulating and strengthening the immune response
 Vitamin K

  •  Blood clotting problems
  • also works with vitamin D to regulate calcium in the body




What are mineral deficiencies?

If you are not absorbing enough minerals, you may be low on the following:
 Choline
 Choline may be a non-essential B vitamin, but it is important for cell membranes and for the production of the neurotransmitter acetylcholine, which has a role in memory and muscle control[33]. 

A lack of choline is unlikely, but it can cause muscle damage and non-alcoholic fatty liver disease (NAFLD)[34]
 Potassium
 Potassium is a key electrolyte and so is important for controlling the balance of fluids in the body[35]. It also plays a critical role in nerve transmission and muscle contractions, particularly the heart[35]. 
Taking too much potassium from supplements can cause stomach pain and diarrhea. High potassium levels may also be the result of kidney disease[36].
 Sodium & Chloride
 Most chloride is gained from salt (sodium chloride), so deficiencies are rare. However, consuming too much salt is very common due to the abundance of salt in everyday food. 

Sodium and chloride are electrolytes that help keep the level of fluids in the body balanced. Sodium also works with potassium in nerve transmissions[37], while chloride helps the body to digest food because it’s an essential component of the fluids in the stomach[38]. 

Consuming excessive amounts of salt is linked to an increase in blood pressure (hypertension), which raises your risk of having a stroke or heart attack[39].
 Calcium
 Calcium is the most abundant mineral in our body as it’s a major constituent of bones and teeth. Calcium is required for muscle contraction, and short-term deficiency may cause muscle cramps, stiffness and poor mobility[40]. 

It’s important to have a good intake in the bone-building years, which are as a baby and again from adolescence to about 30 years of age, especially for females[41]. 

Insufficient amounts can lead to brittle-bone disease (osteoporosis) when you’re older, where your bones break very easily due to the slow loss of bone mass[42]. 

Although calcium toxicity is rare, acute symptoms may include fatigue, muscle weakness, kidney stones and constipation, while long-term excessive calcium intake may increase the risk of developing several diseases[43]. 

Too much calcium can also limit iron absorption[44].
 Phosphorus
 Phosphorus is a mineral that helps to build and maintain strong bones and teeth in conjunction with calcium[45].

Phosphorus also helps release energy from food[46]. 

Acute high doses of phosphorus supplements can cause diarrhea and stomach pain[45]. 

Taking high doses for a long time in the absence of adequate calcium intake can increase bone fracture risk[47].
 Magnesium
 Magnesium is important for energy regulation, muscle and, nerve function[48]. 

Taking high doses of magnesium for a short time can cause diarrhea, nausea, vomiting and abdominal cramping[49].
 Iron
 Iron is an essential mineral with several important roles in the body. Its most well-known role is as a key component of hemoglobin, which allows red blood cells to transport oxygen around the body[50].
 Iron deficiency, which can lead to iron-deficiency anemia, is one of the most common micronutrient deficiencies globally[51]. 
It is a particular issue for menstruating women due to monthly blood loss[50].
 Excessive iron intake in one sitting can cause constipation, nausea and vomiting, especially if food is not eaten at the same time[52].
 Zinc 
 Zinc plays roles in the immune system, including wound healing, and growth and development[53].



 Zinc deficiency affects an estimated two billion people[54]. 
In children, this can cause growth retardation and an impaired immune system resulting in an increased risk of infections[53]. 



Taking high doses of zinc over a long period reduces the amount of copper that the body can absorb. This can lead to anemia and the weakening of bones[55].
 Copper
 Copper plays a vital role in the immune system through antioxidant defense and its involvement in white blood cell production[56]. 
It’s also needed for iron metabolism and, therefore, the formation of hemoglobin[57]. 
Both copper deficiency and toxicity are relatively rare[58]. 
Taking high doses of copper can cause stomach pain, diarrhea and nausea[57].
Iodine
Population effects of severe iodine deficiency, termed iodine deficiency disorders (IDDs), include endemic goiter, hypothyroidism, cretinism, decreased fertility rate, increased infant mortality, and mental retardation.









































How will you test the presence of starch in food?
Take small quantity of the food items to be tested. Put 2-3 drops of iodine solution on it. Observe the colour of the food item. Blue-black colour indicates the presence of starch in the tested food item.

How will you test the presence of Protein in food?
Proteins are needed for the growth and repair of our body. Foods containing proteins are often called ‘Body Building Foods’. Test if a food item contains protein. 
  1. Take a small quantity of the food items to be tested.
  2. Grind/mash/paste/powder the food item.
  3. Put the food item into a test tube.
  4. Add 10 drops of water and shake the test tube.
  5. Using a dropper add two drops of copper sulphate solution to the test tube.
  6. Add 10 drops of caustic soda solution and shake the test tube.
  7. Observe the colour of the mixture.
  8. Violet colour indicates the presence of proteins in the tested food item. 
How will you test the presence of Fats in food?
Fat is a major source of energy and also aids your body in absorbing fat soluble vitamins. You need a minimum of 10 to 20 percent of your overall calories as fat .Test if a food item contains fat. 
  1. Take a small quantity of the food item to be tested.
  2. Wrap the food item in a piece of paper and crush it.
  3. Straighten the paper.
  4. Dry the paper by keeping it in sunlight for a while.
  5. Observe the paper.
  6. An oily patch on the paper indicates the presence of fats in the tested food item. 

BALANCED DIET

 The food we normally eat in a day is our diet. For growth and maintenance of good health, our diet should have all the nutrients that our body needs, in right quantities. Not too much of one and not too little of the other. The diet should also contain a good amount of roughage and water. Such a diet is called a balanced diet.

DEFICIENCY DISEASES

A person may be getting enough food to eat, but sometimes the food may not contain a particular nutrient. If this continues over a long period of time, the person may suffer from its deficiency. Deficiency of one or more nutrients can cause diseases or disorders in our body. Diseases that occur due to lack of nutrients over a long period are called deficiency diseases.
  • If a person does not get enough proteins in his/her food for a long time, he/she is likely to have stunted growth, swelling of face, discolouration of hair, skin diseases and diarrhoea.
  • If the diet is deficient in both carbohydrates and proteins for a long period of time, the growth may stop completely. Such a person becomes very lean and thin and so weak that he/she may not even be able to move.
All deficiency diseases can be prevented by taking a balanced diet.
Summary
  • The major nutrients in our food are carbohydrates, proteins, fats, vitamins and minerals. In addition, food also contains dietary fibres and water.
  • Carbohydrates and fats mainly provide energy to our body.
  • Proteins and minerals are needed for the growth and the maintenance of our body.
  • Vitamins help in protecting our body against diseases.
  • Balanced diet provides all the nutrients that our body needs, in right quantities, along with adequate amount of roughage and water.
  • Deficiency of one or more nutrients in our food for a long time may cause certain diseases or disorders.
