• Yogurt dates back over 5,000 years to Central Asia and Mesopotamia, with early uses by Turkish and Mongolian cultures. It gained Western scientific recognition through Ilya Mechnikov, who linked it to longevity.
• Yogurt is created by fermenting milk with beneficial bacteria like Lactobacillus bulgaricus and Streptococcus thermophilus, enhancing flavor, thickness and digestibility.
• Yogurt is rich in protein, probiotics, calcium, vitamin D, B vitamins, potassium and magnesium, supporting gut health, immunity, bones and metabolism.
• While generally healthy, flavored yogurts may contain excess sugar and conventional options can include pesticide or hormone residues. Choose plain, organic, grass-fed yogurt for optimal benefits.
• Yogurt is versatile globally, used in savory dips like tzatziki and raita, sweet drinks like lassi, and as a base for marinades, baked goods and spreads.

Yogurt is a cultured dairy product created through the fermentation of milk by beneficial bacteria, primarily Lactobacillus bulgaricus and Streptococcus thermophilus. This process thickens the milk, imparts a tangy flavor and enhances digestibility by breaking down lactose.

Origins and historical significance

The origins of yogurt trace back over 5,000 years to Central Asia and Mesopotamia, where nomadic tribes fermented milk in animal skins. Historical records suggest that Turkish and Mongolian cultures were among the first to consume it. Greek physician Hippocrates (460–370 BCE) praised its digestive benefits, while Genghis Khan’s armies reportedly relied on yogurt for endurance.

Yogurt entered the Western world when Russian biologist and Nobel laureate Ilya Mechnikov, from the Institut Pasteur in Paris, linked Bulgarian yogurt consumption to longevity, sparking scientific interest in its probiotic properties. Today, yogurt is a global staple, loved for its health benefits and culinary adaptability.

Nutritional powerhouse

Yogurt delivers a concentrated dose of nutrients that support digestion, immunity and overall health. Depending on the type (whole, low-fat, Greek or Skyr), its nutritional benefits include:

• Protein to support muscle repair. Greek yogurt offers nearly double the protein of regular yogurt.
• Probiotics like bifidobacteria and lactobacillus to improve gut health and immunity.
• Calcium and vitamin D for bone strength.
• B vitamins like B12 and riboflavin aid energy metabolism and neurological health.
• Potassium and magnesium help regulate blood pressure and muscle function.

Is yogurt healthy or harmful?

Yogurt is overwhelmingly beneficial for most people, offering numerous health advantages, though certain considerations apply.

It boosts gut microbiota, alleviating bloating and IBS symptoms, while studies suggest probiotic yogurt improves insulin sensitivity, lowering diabetes risk. Its high protein content also supports weight management by curbing cravings. However, for some individuals, lactose intolerance may cause discomfort – switching to lactose-free or plant-based alternatives can help. Additionally, flavored yogurts often contain added sugars that negate health benefits, making plain, unsweetened varieties the best choice.

When selecting yogurt, opting for organic over conventional minimizes exposure to harmful substances. Conventionally raised cows may consume feed treated with pesticides like glyphosate or atrazine, traces of which can end up in milk. Non-organic dairy often contains synthetic growth hormones (rBST) and antibiotics, which pose long-term health risks. While rare, heavy metals such as cadmium and lead may also contaminate yogurt due to polluted soil or water sources.

For the highest quality, choosing grass-fed, organic or biodynamic yogurt ensures higher levels of beneficial nutrients like omega-3s and conjugated linoleic acid (CLA), a cancer-fighting fatty acid. By prioritizing these wholesome options, individuals can support both digestive wellness and long-term health while avoiding the pitfalls of industrialized food production.

Yogurt in culinary traditions

From breakfast bowls to marinades, yogurt’s creamy texture and tang enhance countless dishes. Here’s how cultures worldwide harness its magic:
