Is yoghurt good for you?

Yoghurt - in particular Greek yoghurt - is widely recognised as a health food due to its beneficial nutrients and probiotici. It is a versatile ingredient that can be added to a variety of wholesome meals. Eaten by millions across the globe, yoghurt is a fermented food made by mixing milk with live bacteria (probiotics).

Questo batterio benefico trasforma lo zucchero naturale del latte (lattosio) in acido lattico che addensa il latte, conferendo allo yogurt la sua caratteristica consistenza e il sapore acidulo. Grazie a questi popolari benefici per il benessere, la domanda dei consumatori per lo yogurt è più alta che mai.

Today's yoghurt aisle offers a variety of flavours and ingredients. But what are the health benefits of natural yoghurt?

Reema Pillai è una dietista privata con sede a Londra presso Dietitian Fit & Co. Spiega che lo yogurt fornisce nutrienti vitali come proteine, vitamina B12, calcio e potassio. Poiché è un alimento fermentato, è anche una buona fonte di probiotici. Questi supportano la diversità e la popolazione dei nostri batteri intestinali sani, migliorando la salute digestiva e l'immunità.

Probiotici

Packed with probiotics, natural yoghurt contains good bacteria that improve digestion and boost your immune system.

Calcio

Yoghurt is a good source of calcio - a mineral the body needs to keep our bones strong. Calcium is also essential for muscle movement, blood circulation, hormone release, and for keeping your nervous system working.

Vitamine

Lo yogurt a base di latte è ricco di vitamina B12 (riboflavina). Questo tipo di vitamina aiuta a convertire il cibo in energia, stimola il nostro metabolismo e mantiene le cellule funzionanti. Molti yogurt sono anche arricchiti con vitamina D, che è cruciale per la salute delle ossa.

Potassio

Yoghurt is rich in potassio - a mineral that balances fluids, supports nerve function, and regulates blood pressure.

Proteine

Le proteine sono composte da amminoacidi che aiutano nella riparazione dei muscoli e delle ossa. Mangiare yogurt può aumentare l'assunzione di proteine - soprattutto lo yogurt greco che è ancora più ricco di proteine.

Gli studi dimostrano che le forme naturali di yogurt possono migliorare la salute dell'intestino, rafforzare il sistema immunitario e persino aiutare nella gestione di condizioni come l'osteoporosi, le malattie cardiache e il diabete. Tuttavia, non tutti gli yogurt sono salutari - nonostante ciò che è scritto sul vasetto.

Pillai says: "Some yoghurts are marketed as being low fat or fat-free, and although they are lower in calories, they often contain added sugars or sweeteners to replace the flavour of removing the fat.

"Any flavoured yoghurt is likely to be sweetened using sugar, or a form of sweetener, so it is important to check these flavoured yoghurts before buying."

Flavoured and fruit yoghurts

Some products, such as flavoured or shop bought fruit yoghurts often contain added sugar. In stark contrast to the health benefits listed above, eating too much sugar can harm your health and raise your chance of obesity, diabetes, and heart disease. A combination of fruit and yoghurt might seem a healthy choice, but the added sugars and flavoured syrups found in the fruit compartment of a yoghurt pot will significantly increase its sugar content.

Dolcificanti artificiali 

While sugar-free options may sound good, research suggests that yoghurt containing artificial sweeteners might disrupt your gut function and contribute to weight gain.

Low/fat-free yoghurts

Low-fat or fat-free yoghurts often come with added sugar to improve taste and compensate for the lack of fat. It’s worth pointing out that full-fat yoghurt can still be a part of a healthy diet when consumed in moderation.

When it comes to choosing yoghurt, it's important to go for those containing good bacteria. Pillai suggests checking that the label contains phrases such as 'live' and 'active' cultures, or includes the names of certain bacteria in the ingredient list.

The most popular are bacteria known as:

  • Lactobacillus.

  • Streptococcus.

  • Bifidobacterium.

She adds: "These bacteria are known to provide healthful effects, and can be found in many yoghurts such as Greek and Icelandic yoghurts, as well as kefir."

What to look out for on the label:

Plain yoghurt - such as Greek yoghurt - is less likely to contain added sugar and is particularly rich in protein. Scan the ingredients list first to check there's no added sugar in the product before buying.

Prebiotici are a type of fibre that feed the good bacteria in your gut. While some yoghurts have prebiotici added already, you can also pair plain yoghurt with prebiotic-rich foods such as chopped banana, honey or chicory root to further boost your gut health.

Look for 'live and active cultures' on the yoghurt label. This means it has an excellent source of good bacteria to help keep your gut happy.

Choose yoghurt with a recent production date and eat it before the best before date. Probiotic bacteria are most active when fresh and are less effective after being in prolonged storage conditions.

"Yoghurt is safe for the majority of people to consume," says Pillai. "But there are a small number of people with l'intolleranza al lattosio or even an allergy to cow's milk."

If you're lactose intolerant - studies show that the friendly bacteria found in yoghurt actually help break down some of the lactose, making it easier to digest than other dairy foods. However, it's still a good idea to start with a small amount of yoghurt, see how you get on and stop if you feel uncomfortable.

If you have a cow's milk allergy - you should not eat yoghurt as it’s primarily a dairy product. People with milk allergies may have a severe reaction to eating even a small amount of yoghurt.

Pillai suggests that someone with a cow's milk protein allergy can opt for a plant-based yoghurt alternative, such as soy yoghurt.

"Many of these plant-based alternatives have had bacterial cultures added to them," she says. "So they can still be beneficial for our overall health. However, it is important to look for these plant-based yoghurt alternatives that have not been heat treated, as this will otherwise kill the bacteria present in these foods."

Lo yogurt naturale è un'ottima fonte di batteri buoni, proteine, calcio, vitamine e minerali. Può supportare la salute intestinale e contribuire al corretto funzionamento del tuo corpo. Tuttavia, come avverte Pillai, non tutti gli yogurt sono uguali.

Remember to:

  • Read the labels carefully.

  • Choose plain yoghurt with no added sugars or flavours.

  • Check for a recent production date.

This way, you can enjoy the benefits of yoghurt without any negative effects on your health.

If you're unsure about which supermarket yoghurt to choose, why not make your own?

Easy yoghurt recipe

Pillai consiglia che un modo rapido e semplice per aggiungere lo yogurt alla tua dieta è preparare delle ciotole di yogurt. Queste possono essere consumate a colazione, come spuntino o anche come dessert:

  1. Metti 2-3 cucchiai di yogurt vivo in una ciotola.

  2. Top with some fruit such as sliced banana and a handful of berries.

  3. Add in 30 grams of mixed unsalted nuts or seeds come i semi di zucca.

  4. Enjoy.

And here's a simple ricetta per la slow cooker for making healthy, natural yoghurt that's free of sugars and artificial ingredients.
