Yoghurt and its benefits

Yoghurt and its benefits
April 29, 2024

How is yoghurt manufactured, and what is it?

  • A common dairy product produced by fermenting milk with microorganisms is yoghurt.
  • Lactose, the natural sugar contained in milk, is fermented by "yoghurt cultures," the bacteria used to manufacture yoghurt. Lactic acid, which is produced during this process and gives yoghurt its distinct flavour and texture, causes milk proteins to curdle.
  • You may make yoghurt with any kind of milk. Whole milk varieties are regarded as full fat, while skim milk varieties are regarded as fat-free.
  • Plain yoghurt has a tangy flavour and is thick and white when no colourants are added. Nevertheless, additional additives like sugar and artificial flavours are included in the majority of commercial brands.
  • Consuming yoghurt has been linked to improved health in a number of populations. However, there is little data on the nutritional value and overall health benefits of yoghurt for older persons. Yoghurt is a great source of protein, high in calcium, zinc, B vitamins, and probiotics. It can also be supplemented with vitamin D and extra probiotics that have been linked to improved health. Numerous dietary deficits and health issues related to under- and overnutrition, such as musculoskeletal disability, immunosenescence, cardiometabolic disorders, and cognitive impairment, are linked to ageing. Yoghurt is also easily available and easy for the elderly population, making it a workable strategy to improve the nutritional status of older persons. Only a small number of studies—the majority of which are observational—have explicitly examined how yoghurt affects older persons' nutritional and health conditions.

Here are some benefits of yoghurt:

  • It has a lot of vital nutrients.
  • Almost every nutrient your body needs is present in some form in yoghurt.
  • It is well recognised for having a high calcium content, which is essential for strong bones and teeth. You get 49% of your daily calcium requirements with just one cup.
  • It also contains a lot of B vitamins, especially riboflavin and vitamin B12, which may help prevent heart disease and several birth abnormalities involving the neural tube.
  • Additionally, one cup supplies 28% of your daily needs for potassium, 10% for magnesium, and 12% for phosphorus. Numerous biological functions, including blood pressure regulation, metabolism, and bone health, depend on these minerals.
  • Yoghurt is often supplemented with vitamin D, a substance that it does not naturally possess. In addition to boosting immune system and bone health, vitamin D may lower the chance of developing certain illnesses, such as depression and heart disease.
  • It has a lot of protein.
  • Protein content of yoghurt is outstanding, with almost 12 grammes every 8 ounces (227 grammes).
  • It has been demonstrated that protein supports metabolism by raising energy expenditure, or the total quantity of calories burned over the day.
  • Consuming adequate protein also helps control hunger by boosting the release of hormones that indicate fullness. It might assist in lowering your total caloric intake, which is advantageous for managing your weight. In a 2014 study, those who ate yoghurt as a snack had 100 fewer calories and felt less hungry at supper than those who ate lower-protein snacks that had the same caloric content.
  • Greek yoghurt, a very thick, strained type, has much more of an impact on increasing fullness than regular yoghurt. With 20 grammes of protein per 7 ounces (200 grammes), it has more protein than ordinary yoghurt.
  • More than other dairy products like whole or skim milk, Greek yoghurt may have the ability to regulate appetite and postpone feelings of hunger.
  • Certain types might improve intestinal health.
  • Probiotics, or living bacteria, are added to some varieties of yoghurt after it has been pasteurised or were included in the starting culture. When taken, these might improve digestive health.
  • Many yoghurts have undergone pasteurisation, a heat-treatment process that eliminates the good bacteria they contain. Because of different storage temperatures and other circumstances, even some yoghurt variants that are labeled as containing "live, active cultures" frequently experience some probiotic loss. That being said, the easiest way to find the finest probiotics is to still read the label and look for one that has live, active cultures. Probiotics like Lactobacillus and Bifidobacteria, which are present in yoghurts, have been demonstrated to alleviate the distressing signs and symptoms of irritable bowel syndrome (IBS), a prevalent condition affecting the colon.
  • In one systematic review, numerous studies were examined wherein individuals with IBS routinely ingested yoghurt or fermented milk that included Bifidobacteria. They discovered that after two to eight weeks, 50% of the research on the topic demonstrated a notable reduction in IBS-related symptomatic stomach pain.
  • In another study, women with mild digestive symptoms reported better health-related quality of life and less feelings of upset stomach when they drank yoghurt with Bifidobacteria. Additionally, a number of studies have discovered that probiotics may guard against diarrhoea and constipation brought on by antibiotics.
  • It might improve your immunity.
  • Regular yoghurt consumption can boost your immune system and lower your risk of catching diseases, particularly if the product contains probiotics.
  • Probiotics have the ability to lessen inflammation, which has been connected to a number of illnesses, including intestinal problems and viral infections. According to research, probiotics may occasionally also aid in lowering the frequency, length, and intensity of colds. Additionally, yoghurt has immune-boosting qualities in part because it contains trace minerals including zinc, magnesium, and selenium, which are well-known for their benefits to immune system health.
  • Yoghurts enhanced with vitamin D may strengthen immunity even more. Studies have looked into vitamin D's ability to fend off ailments including the flu and the common cold.
  • It might improve cardiac health.
  • One of the reasons yogurt's perceived health benefits are sometimes debatable is its fat content. With a minor proportion of monounsaturated fatty acids, it is primarily composed of saturated fat. It was always thought that saturated fat was the cause of heart disease, but more recent study has revealed that the situation is more nuanced. However, low-fat and fat-free yoghurt types continue to be well-liked in the US.
  • It's crucial to consider the source of saturated fat as well as the kinds of fats that are substituting it while debating its healthfulness.
  • Saturated fats from processed fast food do not have the same effects on the body as saturated fats from full-fat dairy products, such yoghurt. It's not entirely evident from the data that yogurt's fat is bad for you. In fact, further research is necessary to fully understand the potential benefits to heart health. Consuming saturated fat from whole milk products raises HDL (good) cholesterol, which may help to protect the heart, according to some research. Consuming yoghurt has been shown in several trials to lower the risk of heart disease overall.
  • Dairy products like yoghurt can also aid in lowering excessive blood pressure, a significant risk factor for heart disease. Those who have already been diagnosed with high blood pressure appear to be most affected.
  • It might encourage controlling weight.
  • Particularly Greek yoghurt offers a number of qualities that could support weight control. First of all, it has a lot of protein, which increases levels of hormones that suppress hunger, such as peptide YY and GLP-1, when combined with calcium.
  • Yoghurt consumption has also been linked to decreased body weight, body fat percentage, and waist circumference, according to a number of studies.
  • Consuming full-fat dairy products, such as yoghurt, may lower the prevalence of obesity, according to one review. This goes against the conventional wisdom on the relationship between eating full-fat dairy products and gaining weight.
  • Yoghurt consumers generally eat better than non-yogurt consumers, according to other studies. This is partially because of its relatively low calorie content and increased nutritional content.

Yoghurt consumption for elderly:

As of now, the strongest evidence supporting the potential benefit of yoghurt consumption on health outcomes for the elderly comes from observational studies, or indirectly from research examining the impact of probiotics, which are abundant in yoghurt, or isolated nutrients on various health outcomes. The impact of yoghurt as a whole diet on biological indicators of health or disease in the elderly has not been well-studied in clinical trials. However, the research that is now available is positive and indicates that, when included in a balanced diet, yoghurt may be able to significantly improve the nutritional and health status of the elderly. These findings further reinforce the need for more research on yogurt's potential benefits for active, healthy ageing. To assess the long-term effects of yoghurt on older persons' nutritional status and health, in particular, longer-term clinical trials and research are required.
