Explained: Difference between curd and yoghurt

With the arrival of summer season, there is an automatic shift in our culinary preferences. From heavy foods, the urge shifts to lighter and gut-friendly foods that are easy to digest and keep the body calm and cool too. In this shift, probiotic foods like curd and yoghurt play a role. As we talk about curd and yogurt as key summer foods, the question also arises that are they both same or different? Let us explore and find out.
Well, they might look alike but they are different. Yoghurt and curd are both dairy products that are vastly different from each other. Take a look at the differences.
Production
Curd is made by fermenting milk with the help of Lactic Acid bacteria. This bacteria reacts with casein, a globular protein found in milk. The bacteria then produces energy during the reaction. This lactic acid then reacts with the globular proteins present in milk, denatures them, and results in the formation of curd. In a post on Instagram, celebrity nutritionist and author Rujuta Diwekar once wrote, "Curd is also a well-documented intervention for regulating cholesterol levels, reducing BP and promoting weight loss. It works that much better in the elderly and the young as it prevents constipation and makes it easy to chew on raisins."

Yoghurt, on the other hand, is made by fermenting milk using live strains of two bacteria- Lactobacillus bulgaricus and Streptococcus thermophilus. The bacteria reacts with the sugar present in milk. The reaction produces lactic acid which then reacts with the protein in the milk and forms yogurt.

Consistency and texture
The first and foremost difference comes from the varying bacterial strains used in curd and yoghurt fermentation. Curd typically has a looser texture and a milder flavour, as its fermentation process is less controlled. Yoghurt, on the other hand, undergoes a more controlled fermentation, resulting in a thicker, custard-like consistency and a distinct tangy taste.
Calories
In terms of calories, curd and yoghurt are relatively similar, with both typically containing around 60-70 calories per 100 grams. However, the calorie content may vary slightly depending on factors such as the milk used and any added ingredients like sugar or fruit.
Nutritional profile
They both are excellent sources of protein, calcium, and probiotics, but their nutritional profiles differ due to their fermentation processes. The bacterial cultures in yoghurt break down lactose, the natural sugar in milk, more effectively than those in curd. Hence, yoghurt is often better digested by individuals with lactose intolerance. Moreover, yoghurt tends to have higher concentrations of probiotics, which are beneficial for gut health, than traditional curd. Yogurt is said to provide probiotics, vitamins, and minerals, all of which may boost immune health and prevent certain illnesses. Regular consumption of yoghurt has been associated with a lower risk of heart disease and stroke due to its beneficial effects on cholesterol levels, blood pressure, and inflammation. Curd is rich in healthy fats, proteins, sodium, calcium, magnesium, vitamin A, D, and B-12 and potassium, which helps boost digestion, improve bone health, helps in weight reduction and keep the heart healthy too. Also, curd is a good source of calcium and vitamin D, which are essential for strong bones and teeth, reducing the risk of osteoporosis and fractures. The probiotics found in curd can help regulate bowel movements, prevent constipation, and promote overall digestive health. Additionally, curd contains enzymes like lactase, which aids in the digestion of lactose, making it easier to digest for individuals with lactose intolerance. The nutrients in curd, particularly vitamin B12 and riboflavin, contribute to healthy skin. Applying curd topically or consuming it regularly may help improve skin texture and promote a radiant complexion. Yogurt is a good source of high-quality protein, which is essential for muscle building, repair, and recovery after exercise, making it an ideal post-workout snack. The probiotics in curd can help reduce inflammation in the body, potentially lowering the risk of inflammatory conditions such as arthritis and inflammatory bowel disease.
Curd is a good source of calcium and vitamin D, which are essential for maintaining strong and healthy bones. The probiotics in curd play a crucial role in supporting immune function by stimulating the production of immune cells and enhancing the body's defense mechanisms against infections. Also, having anti-fungal properties, curd can be your natural remedy to clear out stubborn dandruff and improve scalp health and also improve the hair growth. Curd provides a good balance of protein, carbohydrates, and fats, contributing to overall energy needs. It is rich in essential vitamins (B vitamins, vitamin D) and minerals (calcium, phosphorus, magnesium).
Curd is a good source of calcium and vitamin D, which are essential for maintaining strong and healthy bones. Calcium is necessary for bone formation and density, while vitamin D helps in calcium absorption. Including curd in your diet can help prevent osteoporosis and reduce the risk of fractures and bone-related disorders. Some studies suggest that consuming curd regularly may help lower blood pressure and reduce the risk of heart disease. The potassium and magnesium in curd are believed to play a role in this benefit. Curd is a rich source of calcium and phosphorus, which are essential minerals for bone strength and density. Consuming an adequate amount of calcium helps to prevent osteoporosis and maintain healthy bones and teeth, especially as you age. Some studies suggest that probiotics can influence the gut-brain axis, potentially reducing stress and anxiety levels.
Regular consumption of curd can help lower bad cholesterol levels (LDL) and increase good cholesterol levels (HDL). It also helps manage blood pressure due to its potassium content, which balances sodium levels in the body.
Curd and yogurt, rich in probiotics, are beneficial for diarrhea as they help restore the balance of good bacteria in the gut. They contain live cultures such as Lactobacillus acidophilus, which promote digestion and alleviate symptoms of diarrhea by inhibiting the growth of harmful bacteria. Additionally, their cooling properties soothe the stomach lining, providing relief from discomfort and aiding in faster recovery.
