Isn't yoghurt an ultra-processed, sugar-laden snack that we should avoid buying when we're in the supermarket?
酸奶不是超加工、含糖的零食吗？我们在超市应该避免购买吗？
The truth is a bit more complicated, and it all depends on the yoghurt.
事实更为复杂，这完全取决于酸奶的类型。
Some do have a high sugar and fat content and offer few other health benefits.
有些酸奶确实含糖和脂肪高，几乎不提供其他健康益处。
But when it comes to yoghurt, they are not the whole story.
但就酸奶而言，它们并不是全部。
Let's look at some of the potential benefits.
让我们看看一些潜在的好处。
Yoghurt is made by fermenting milk, which produces a number of live bacterial cultures.
酸奶是通过发酵牛奶制成的，这会产生活性细菌培养物。
These helpful bacteria interact with our gut flora and have been associated with better digestive health.
这些有益细菌与我们的肠道菌群相互作用，并与更好的消化健康相关。
It's possible that this could lead to reduced symptoms in people with conditions such as irritable bowel syndrome.
这可能会减轻肠易激综合征等患者的症状。
It's also been suggested that regularly consuming yoghurt could reduce inflammation and the risk of developing some kinds of bowel cancer.
也有人建议，定期食用酸奶可以减轻炎症，并降低患某些肠癌的风险。
However, many types of yoghurt available in shops are pasteurised, which kills most of the helpful bacteria.
然而，商店里的许多酸奶都经过巴氏杀菌，这会杀死大部分有益细菌。
As well as providing calcium, B vitamins and phosphorus, yoghurt is high in protein.
除了提供钙、B族维生素和磷，酸奶还富含蛋白质。
Protein can be important for muscle development, bone strength, and for controlling our appetites.
蛋白质对肌肉发育、骨骼强度和控制食欲很重要。
Again, the choice of yoghurt can be important.
同样，酸奶的选择可能很重要。
Strained, Greek-style yoghurt is thicker than regular yoghurt and is particularly high in protein.
滤过的希腊式酸奶比普通酸奶更稠，蛋白质含量特别高。
200g contains around double the amount of protein found in 200ml of milk.
200克酸奶的蛋白质含量大约是200毫升牛奶的两倍。
The effect of fat in yoghurt is more complex.
酸奶中脂肪的影响更为复杂。
It is high in saturated fat, which could be a risk factor for heart disease.
它富含饱和脂肪，这可能是心脏病的风险因素。
However, some studies suggest that saturated fat from whole milk can provide beneficial forms of cholesterol, which might protect heart health.
然而，一些研究表明，全脂牛奶中的饱和脂肪可以提供有益的胆固醇形式，这可能保护心脏健康。
However, more research in this area is needed, and current UK government advice is to look for low-fat yoghurt.
然而，这个领域还需要更多研究，目前英国政府的建议是选择低脂酸奶。
There are many potential benefits as long as we choose the right yoghurt.
只要我们选择合适的酸奶，就有许多潜在好处。
Unsweetened Greek yoghurt that retains live bacteria is likely to be the best choice for our health.
保留活性细菌的无糖希腊酸奶可能是我们健康的最佳选择。
