The human body needs nourishment in a balanced manner to carry out all its biological processes optimally. The micro and macronutrients one needs are not naturally synthesised inside the human body. Hence, your diet plays a significant role in this scenario. The nutritional problems in India mainly arise when there is a lack of essential nutrients within the human body.

If you are worried about common nutritional problems, don't fret. Keep reading to learn all you need.

A nutritional problem or deficiency occurs when an individual's body experiences a shortage of essential nutrients or some specific nutrient. Such problems can lead to several health issues, such as anaemia. However, consuming a balanced diet can prevent these problems.

Nutritional problems or deficiencies occur when an individual's nutrient intake drops consistently below the recommended level. Now, depending on the cause, the nutritional problems in India can be categorised into two classes. These are illustrated below:

1. Primary Nutritional Deficiency

This deficiency occurs when an individual lacks specific essential nutrients. Consuming proper foods or supplements can resolve this condition. Usually, this form of insufficiency can stem from poor dietary habits, inadequate food supply for the body, economic factors and lack of information on nutritious foods.

Among populations with limited access to fresh fruits and vegetables, there are often vitamin deficiencies. Addressing primary nutritional deficiencies typically involves dietary improvements to include a variety of foods from all food groups and emphasising nutrient-dense options. Moreover taking some supplements may also be necessary when changing only the diet does not work.

2. Secondary Nutritional Deficiency

Secondary deficiencies take place because of limited nutrient absorption due to the presence of a medical illness.  This form of insufficiency is usually caused by an underlying medical condition, taking certain drugs, surgical interventions, persistent alcoholism and age-related alterations in the digestive system.

Management of secondary deficiencies involves treating underpinning conditions that cause them. It also involves dietary modifications and sometimes intravenous provision of nutrients for extreme cases. Through addressing causative factors and providing appropriate nutritional care, secondary nutritional deficits can be minimised.

Some of the medical issues for this include cystic fibrosis, lactose intolerance, celiac disease, pernicious anaemia and pancreatic insufficiency. Malnutrition arising from this deficiency can be more challenging to treat than the primary deficiency.

The symptoms associated with nutritional problems in India depend on the type of nutrient the body lacks. Listed below are the general symptoms that an individual facing nutritional deficiency can experience:

• Menstrual Issues Like Very Heavy Cycles, or Missed Periods: Hormonal imbalances that result from lack of nutrients can disrupt the normal menstrual cycle.
• Poor Levels of Concentration: Inadequate nutrition, specifically iron and vitamin deficiencies, can impair cognitive functions and focusing abilities.
• Loss of Hair: Failure to obtain biotin, zinc and iron may increase hair loss and thinning.
• Heart Palpitations: Magnesium and potassium deficiencies are responsible for arrhythmias in the heart.
• Periods of Lightheadedness: A lack of iron or vitamin B12 intake causes anaemia, which leads to dizziness and light-headedness.
• Sleepiness: Prolonged tiredness and sleepiness are associated with nutritional shortfalls in substances such as iron and vitamin D.
• Fainting: Inadequate amounts of vital vitamins and minerals reduce blood pressure, causing fainting spells.
• Depression: Deficiencies in omega-3 fatty acids, B vitamins, and magnesium deprive the brain cells of proper functionality, which causes deterioration into depression.
• Pallor or Pale Skin: Iron deficiency often manifests itself through pale skin due to decreased levels of haemoglobin.
• Difficulty in Breathing: Difficulty breathing normally occurs when severe anaemia arises due to an insufficient supply of iron.
• Abnormal Food Cravings: Hunger for non-nutritive stuff, such as dust or ice (pica), may be a symptom of a lack of iron or zinc.
• Fatigue: Chronic weariness and energy deprivation result from insufficiencies in iron, vitamin D, and other key nutrients.
• Constipation: Insufficient fibre and magnesium intake, combined with inadequate water, can result in digestive problems and hard stools.
• Weakness: Protein, iron, and other important nutrients can be deficient and lead to generalised muscle weakness.
• Numbness and Tingling of the Joints: Numbness and tingling in the elbows usually occur when people do not have sufficient vitamin B12 and folate.

India has to grapple with significant nutritional challenges due to economic, cultural, and environmental factors. Given below are some common nutritional problems in India resulting from these factors:

1. Vitamin D-related Nutritional Problems

Vitamin D is an essential nutrient for maintaining bone health. It is also known to be responsible for the prevention of certain types of cancers. The symptoms of the deficiency of this vitamin include pain in the bones, fatigue, muscle aches and besides these, the individual might also experience weakness.

Long-term deficiencies of this nutrient would result in the softening of bones, autoimmune disorders and cancers.

2. Protein-related Nutritional Problems

Proteins are considered the body’s building blocks. These nutrients are essential when it comes to maintaining muscle mass. Protein-energy undernutrition (formerly known as protein-energy malnutrition) is found in children with seriously low nutrient intake in their growing years. It is also found in older individuals who suffer from anorexia, prolonged periods of starvation or fasting, depression, and limited intake of proper nutritious food.

When it comes to children, there are two commonly found types of protein-energy malnutrition, namely marasmus and kwashiorkor.

Kwashiorkor results in the loss of weight because of having a diet that is predominant in carbohydrates but deficient in proteins.

Marasmus, on the other hand, leads to loss of weight due to a drop in muscle and fat mass in the body.

3. Iron-related Nutritional Problems

Iron is a vital micronutrient essential for several body functions like cognitive function, oxygen transport, immune function, differentiation and growth of cells, physical and mental growth. Deficiency in iron because of either pathological or physiological reasons causes anaemia.

As per the World Health Organisation, anaemia is still one of the major health conditions occurring because of a shortage in the intake of minerals and vitamins. This condition is characterised by a low concentration of haemoglobin.

4. Vitamin B12-related Nutritional Problems

This vitamin is essential when it comes to the generation of energy during the metabolism of fat, carbohydrate, and protein, maintaining a healthy nervous system, and producing red blood cells.

Several studies have shown that the deficiency of this vitamin in Indian individuals exists around 70% to 100%. The deficiency of this nutrient might result in Crohn's disease, celiac disease, parasite infestation, and atrophic gastritis, which involves the thinning of the abdominal lining, pernicious anaemia where a lowered absorption of this vitamin occurs, and megaloblastic anaemia.

5. Iodine-related Nutritional Problems

Iodine is essential for the synthesis of thyroid hormone, which is vital for growth, repair and the regulation of metabolic changes. The deficiency of this nutrient can result in mental retardation and growth abnormalities in children.

6. Vitamin A-related Nutritional Problems

This fat-soluble vitamin is important for healthy eyesight and immune function. The deficiency of this nutrient can lead to blindness and immunity suppression, making one vulnerable to infections.

7. Folate-related Nutritional Problems

Folate, which is a naturally existing form of vitamin B9, is a building block of cells and is vital when it comes to the formation of RNA and DNA. It is an important nutrient for pregnant women because of its role in preventing congenital disabilities such as spina bifida in newborn babies.

On the other hand, the deficiency of this nutrient is also a common nutritional problem for adolescents. Mouth sores, greying of hair, swelling of tongue and fatigue are some of the issues which can arise because of folate deficiency.

8. Vitamin C-related Nutritional Problems

Vitamin C is an essential nutrient responsible for healthy skin and strong immunity. Damaged and dry skin, wounds healing slowly and easy bruising are some of the problems which can arise because of the deficiency of this vitamin.

A majority of the health issues occurring because of nutritional problems in India stop after the deficiency is resolved. But in some of the cases, there might be lasting damage. This generally takes place only when the deficiency has been extreme and is going for an extended period of time.

For instance, a prolonged deficiency of the nutrient thiamine can be linked with depression or stunted growth.

The deficiencies of micronutrients have continued to be a highly significant matter concerning public health in India. Therefore, in order to combat malnutrition and hence nutritional problems in India, the Indian Government has taken initiatives in the form of policy measures, missions, plans and programmes.

Some of them are listed below:

• Special Nutrition Programme, 1970-71
• Nutritional Anaemia Prophylaxis Programme, 1970
• National Plan of Action on Nutrition, 1995
• National Nutrition Mission, 2003

However, several major nutritional problems in India exist even today, and the Government is making continuous efforts to deal with them.

On an individual level, for overcoming nutritional problems in India, one needs to have a well-balanced diet containing nutrients in recommended proportions. If someone is deficient in a particular nutrient, he or she must consume foods rich in that specific nutrient.

Malnutrition is a complex issue in India, affecting macro and micronutrient deficiencies. A multi-dimensional approach is required to address this issue and improve the nutrition status among the population. Some such strategies include:

1. Food Security Programs

Enhancing PDS and other existing programs to ensure the availability of affordable, nutritious staples like wheat, rice and pulses.

2. Dietary Supplementation

Mission Poshan 2.0’s Poshan Abhiyan is one example of a food that provides essential micronutrients like iron and folic acid to pregnant women and young children.

3. Improving Healthcare Infrastructure

It will also require enhancing healthcare facilities, especially in rural areas, to detect and manage malnutrition on time, including training healthcare providers.

4. Education and Awareness

Creating awareness through public education campaigns and mass media on balanced dieting, emphasising locally available seasonal fruits and vegetables.

5. Promoting Kitchen Gardens

Encouraging households, especially in rural areas, to grow vegetables, fruits, and herbs in kitchen gardens enhances fresh food availability.

6. Livelihood Generation

Providing support for income-generating activities among underprivileged communities increases financial resources for purchasing more nutritious food.

7. Promoting Agricultural Diversity

Encouraging farmers to plant a range of crops, such as millets and ethnic varieties, that help improve dietary diversification and nutrient density.

8. Reducing Food Waste

Adopting approaches that minimise food wastage at every stage, from production through consumption, leads to efficient utilisation of available resources.
