For centuries, fermented milks have provided essential nutrients and health benefits in human diets. Milk fermentation is as simple as adding live ferments to milk, leading to dozens of popular recipes around the world. How different are they?

Get the science facts about Greek yogurt, lassi, skyr, laban, ayran or kefir…

What is Kefir?


Kefir is a drink, started with the kefir grains that clump together various bacteria and yeasts (vs only 2 bacteria in yogurt).
This leads to a double fermentation (lactic + alcoholic) and develops the sour & fizzy attributes of kefir.

  • Lactic acid bacteria: Lactobacillus, Lactococcus, Leuconostoc or Streptococcus
    • Feed on lactose
    • Yield lactic acid: lower pH which coagulates milk proteins
    • Release aromatic diacetyl & acetaldehyde
  • Acetic acid bacteria: Acetobacter occasionally present
    • Feed on sugars to yield organic acids
  • Yeasts
    • Some feed on lactose (i.e. Candida or Kluyveromyces)
    • Some feed on other sugars (glucose) (i.e. Saccharomyces or Kazachstania)
    • Yield CO2 (self-carbonated drink) + alcohol (below 0.05 %)  by alcoholic fermentation

Kefir drinks can also be prepared by fermenting fruit juices, coconut water or molasses. This factsheet will focus on milk kefir.

The cultural origins of Kefir

The name of “Kefir” comes from Turkish “Keyif”, meaning good feeling.
It is originates from Caucasian mountains in Russia & Central Asia and is popular in Middle East, Eastern Europe and Sweden.

Kefir is now emerging in North America (USA) & Japan for its nutritional goodness.

Nutrition & health benefits of Kefir

As all fermented milk product: 

  • Improved digestibility vs milk
  • Higher calcium uptake vs milk
  • Other effects under study (changes in blood lipid profile, anti-inflammatory properties)

Increased micronutrient density

  • After kefir’s yeast fermentation (vit B1, B2, B6, A, niacin, folates)

Research provides reassurance over dairy intake and breast cancer risk

Reassuring results have emerged from an analysis of studies examining the relationship between dairy products and the risk of breast cancer. The evidence suggests that women can continue to enjoy the nutritional benefits of milk and yogurt as part of a healthy diet, without fear of raising their risk of this dangerous disease.

Breast cancer is the most common cancer in women and the main cause of female cancer death. Could something as simple as eating certain foods and avoiding others help to reduce the risk of developing breast cancer?

As dairy consumption and breast cancer rates differ between countries, scientists have previously suggested that consuming dairy products might affect our breast cancer risk. However, the authors of this analysis found no link between breast cancer risk and intake of any of the dairy types investigated.

What influences breast cancer risk?

Researchers believe the development of breast cancer is influenced by many factors, including hormones, diet and alcohol intake. In terms of diet, many epidemiological studies have examined a possible association between dairy intake and breast cancer risk. However, our diets are complex and it is difficult to separate potential effects of dairy products from those of other nutrients.

Some studies have associated higher dairy intake with an increase in breast cancer risk, while others have reported a decrease in risk.

Why might dairy products influence breast cancer risk?

On the one hand, scientists have suggested that the high fat content of some dairy products, such as whole milk and cheese, might increase the risk of breast cancer. Dairy products may also contain growth factors or pesticides that could potentially increase the risk.

On the other hand, calcium and vitamin D in dairy products may actually reduce breast cancer risk, scientists suggest.

‘A main hypothesis suggesting that dairy products may reduce breast cancer risk is based on vitamin D content of these products.’ – Chen et al, 2019.

What does this new literature review show?

The authors searched the medical literature for studies published up until June 2009 that looked at milk (low fat/skimmed milk and whole milk) or yogurt consumption and breast cancer risk. They identified 8 studies conducted around the world – USA, Europe, France, the Netherlands, Norway, Finland and Japan.

The results of the studies were very variable, so the authors analysed all the data to get an overview of what might be happening. They concluded that the findings did not support a role for low-fat/skimmed milk, whole milk or yogurt in the development of breast cancer.

‘Consistently, in our meta-analysis no associations with breast cancer risk were identified for intake of low-fat/skim milk, whole milk, and yogurt.’ – Chen et al, 2019.

Where do we go from here?

The authors highlighted specific challenges in evaluating dairy products and breast cancer risk. In some countries (e.g. the USA) vitamin D is added to dairy products such as milk. As vitamin D might influence breast cancer risk, studies should consider the level of vitamin D in dairy products, the authors say. Another important issue is whether milk is obtained from cows receiving growth hormone, which potentially increases growth factor levels in milk that could stimulate cancer cells to grow more rapidly.

These questions should be addressed in large international studies so that we can gain a better understanding of the relationship between dairy products and breast cancer risk, say the authors.

Breakfast is one of the most important meals of the day and there are many recipes and ways to prepare your breakfast.

Yogurt and fruit: a winning combination!

Having a breakfast that combines two healthy foods, a yogurt and a fruit, is tastefull and could be beneficial to your health.  A study suggests that combining yogurt with fruit may be of great interest providing probiotics, prebiotics and essential nutrients.

Fruit and yogurt have been identified individually as indicators of a healthy diet:

  • Fruits are rich in fiber, potassium, antioxidants, carotenoids, vitamins and have been associated with a reduced risk of cardiovascular diseases.
  • Yogurt is rich in protein, calcium, magnesium, vitamin D, vitamin B12, lactic bacteria and has been associated with a reduced weight gain and risk of type 2 diabetes.Yogurt and fruits : a probiotic prebiotic association - YINI

The association of yogurt and fruits, in addition to being tasty, may confer combining health benefits through the potential interactions between fruit prebiotics and yogurt probiotics: fruits are rich in fiber which promotes the colonization of lactobacilli and bifidobacteria in the colon.

The pleasure of eating drives food choices

Childhood is the prime time for laying the foundations of positive and life-long healthy eating habits. A report from a group of experts, Nurturing Children’s Healthy Eating, shows the key role of families in building good eating habits in children. Every month, we will bring you a summary post, highlighting some of the key messages taken from this report, in order to help families nurture healthier eating habits.

Remember the last time you had a nice meal with friends, enjoying a plate of your favorite food, in great company… and you can understand how the pleasure affects what, why and how much we eat.

Indeed, pleasure can be a lever for encouraging children to eat healthily.

Pleasure drives food choices

For children, eating is part of a learning curve during which they must learn what, when, how and how much to eat. Within this process, pleasure plays a role in driving food choices. This may be particularly true in children, as the other determinants of food choices (e.g. nutrition information, price) play a less prominent role due to their as yet immature cognitive abilities.

However, in a context in which the Western diet is widespread and energy-dense foods are over-abundant, pleasure can also be seen as a threat, adversely affecting both food choices and quantities consumed.

“Pleasure could be a valuable tool in promoting healthy eating because it drives food choices.”

In order to identify the circumstances in which pleasure can stimulate rather than hinder healthy eating, researchers have attempted to understand the mechanisms underlying pleasure and how exactly it drives food choices. Three main types of factors can influence our food choices:

  • Factors related directly to the food we eat
  • Factors related to the context in which we eat
  • Individual factors.

Based on this observation, experts have identified three dimensions of pleasure in eating for children:

  • Sensory pleasure
  • Interpersonal pleasure
  • Cognitive pleasure.

Sensory pleasure: liking food is a matter of flavor, texture and appearance

The pleasure we experience when eating a given food depends on its appearance, texture and taste, but also on its ability to satisfy our energy needs.

The sensory properties of food are indicators allowing us to recognize whether a food is safe and suitable for eating. Through our senses, we are able to identify and remember foods, detecting not only their flavors but also their energy density. Children are unconsciously able to associate the energy density of a food with its flavor and adapt their energy intake accordingly.

Sensory pleasure is partly determined by our innate liking of particular tastes (sweetness, saltiness, umami) and is learned partly in utero and during the first years of life. Infants often prefer the flavor of foods to which they were exposed prenatally and during breast/formula feeding. Their attraction to other types of foods will be shaped by experience. Thus, the eating experiences that parents or caregivers provide for children will be key to forming their future eating habits.

Many studies show that learning to like new foods relies on repeated exposure. However, the extent of this effect will depend on the type of foods proposed and/or on the individual child.

Interpersonal pleasure: social interactions matter

Eating is a social experience. The pleasure of eating is closely related to the social context of the meal. Eating together  with parents, family members or peers, encourages social interactions that are crucial for the development of children’s eating habits.

At family meals, young children learn which foods are culturally preferred by watching and imitating other people. Social eating influences not only children’s food choices, but also their acceptance of new foods. This social modelling is a process that begins early, in the first year of life, and continues throughout childhood.

Studies have also shown that talking about what is eaten can be influential and may act on children’s enjoyment of mealtimes. It can be a valuable way to support healthy eating.

Cognitive pleasure: thoughts influence pleasure of eating

“It’s not enough for a food to be good to eat, it must also be good to think about”. This observation by Claude Levi-Strauss shows that thoughts and ideas also influence our food choices. Eating is associated with a set of thoughts, images and ideas.

The cognitive qualities of a food can be described as:

  • Search qualities (before purchasing)
  • Experience qualities (ascertained after purchase)
  • Credence qualities (qualities indirectly related to the product such as brand, marketing…)

Marketing strategies such as brand, packaging and advertising commonly lend credence to a food product and create positive expectations about it. Hence marketing strategies can act as a lever to influence the pleasure of eating healthful foods in children of all ages.  

However, it must be remembered that the way in which a child comprehends and responds to advertising varies with age and individual characteristics. Children become aware of brand representation between the ages of 3 and 5 years. Until the age of 7 or 8 years old, they tend to perceive advertising as entertaining or informative, which makes them particularly vulnerable to strategies designed to modify attitudes. After this, children start viewing advertising in a more analytical way.

Screen-based advertising, which relies largely on affective claims such as the use of characters, the taste of the food and suggestions that the food is fun, is particularly persuasive, even in older children.

This suggests that marketing strategies may be used to influence the pleasure of eating healthy foods at all ages.

The pleasure of eating is a complex phenomenon that may be divided into three dimensions: sensory pleasure, interpersonal pleasure and cognitive pleasure.

It is time to go back to school… It is also a great opportunity for kids to make a fresh start and may be the right time to adopt long-term healthy eating habits to help them succeed in this new school year.

Excessive sugars intake is a public health issue and the World Health Organization recommends limiting the consumption of added or free sugars to a maximum of 10% of the daily calories in both children and adults.  A recent report from the French health agency ANSES (Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail) warned against excessive sugars intake in children aged 4 to 17: 75% of 4-7 year-olds, 60% of 8-12 year-olds and 25% of 13-17 year-old have excessive sugars intake in France.

A review of data available in different European countries on sugar consumption and sources of sugar intakes showed that:

  • In all countries included in the study, free sugars represent more than 10% of children’s daily calories.
  • Yogurt contributes for less than 8% of children’s total sugar intake, while sweetened products and beverages are the main contributors.
YINI What is the contribution of yogurt to total sugar?

Thus, swapping a sweet snack for a yogurt is a great way to give kids a healthy and nutrient-dense snack while reducing their total daily intake of sugars.

Childhood is the prime time for laying the foundations of positive and life-long healthy eating habits. A report from a group of experts, Nurturing Children’s Healthy Eating, shows the key role of families in building good eating habits in children. Every month, we will bring you a summary post, highlighting some of the key messages taken from this report, in order to help families nurture healthier eating habits.

Considering that the vast majority of meals is taken at home, the quality and accessibility of foods available in the home may play a fundamental role in building healthy habits in children.

“It is essential that families are made aware of the importance of bringing healthy foods into their homes and ensuring their children have access to them.”

The importance of the home environment

In the United States, adults consume around 65 to 72% of the daily energy intake at home, making it a key place to build family healthy eating habits. The quality and quantity of foods available in the home are therefore playing a great role on the health and eating behaviors of all family members. The foods available at home will depend on many factors such as the family resources (financial as emotional), food accessibility, meal preparations…

Family resources influence the home food environment

Family resources, including the financial income as well as the educational level of parents, will contribute to shape the types of foods available in the home.

The family financial incomes and the cost of foods are the main factors influencing the types of foods parents bring into the home. The cost of healthy foods such as fresh fruits and vegetables, lean meats and fish may be usually higher than the costs of high-energy foods such as refined grains, foods with added sugars and fat.

In addition to purchasing power, low-income families may face financial costs and time barriers as parents may have multiple jobs and little time to prepare meals and eat with their children, resulting in higher consumption of fast food or easy-to-prepare meals.

While income has a role to play in the availability of healthy foods in the home, it is not the only factor: unhealthy foods are found in both low-income and high-income families.

Emotional environment affects the quality of family diets

Studies show that the emotional environment may have a major impact on the quality of the family’s diet. Indeed, high levels of parental stress, caused by variety of factors (economic pressure, work and family responsibilities, time restraints…) have been associated with less frequent family meals, more frequent consumption of fast food and sweetened drinks. As stress levels increase, family meals will also become less healthy and children’s weight increases. As much as possible, it is important to try to provide an enjoyable and positive home food environment.

Healthy foods in the home for healthy dietary choices

Food available in the home has a significant impact on children’s dietary choices. At home, parents are gatekeepers and can guide children to the healthy option. According to the experts, a healthy diet that parents can give to their children is a balanced diet with a variety of healthy and nutrient-dense foods in healthy amounts.

Providing healthy foods at home makes children more likely to choose and enjoy the healthy option. Studies show that children eat more fruits and vegetables when there are more healthy foods in the home. Conversely, the availability of energy-dense and nutrient-poor foods makes young family members more likely to opt for sweet and savoury snacks and to consume more high-calories drinks.

The risk of obesity of both parents and children has been associated with the food available in the home. Therefore, it is essential that parents be aware of the importance of trying to provide as much healthy foods as possible in the home.

Making healthy foods accessible

In addition to having healthy foods available in the home, accessibility affects kids’ food choices. Accessibility is about providing foods in places and in forms that are easy to reach and to eat for children and it is also refer to appropriate portion sizes.

How to make healthy foods accessible?

  • Make healthy foods the easy option: Prepare healthy foods so they are appealing and easy to eat. For instance, children are more likely to eat fruits and vegetables if they are peeled and cut.
  • Make healthy foods the happy option: Include healthy foods at the centre of happy occasions such as family celebrations or birthdays, this can help children think of healthy foods as happy foods. For example this summer for your evenings with friends or family, make a tasty yogurt sauce to dip sticks of vegetables.
  • Make water accessible: Ensure that plain water is always easily accessible to ensure children’s hydration.
  • Adapt portions: Adapt portion sizes to the age of children, pay attention and respect their signals of satiety and hunger. Offer smaller portions for less healthy foods and snacks.

Cues for eating in the home influence food choices

Home is the place of many eating signals that will influence immediate food intake and shape the establishment of habits about what, when and how much to eat. Since parents are role models and establish rules about feeding, they provide important eating cues to their children.

However, at home, television viewing is also particularly a powerful cue for children: food advertisements offers cues to eat even in the absence of hunger and promotes the consumption of less healthful foods. Reducing access to television seems to be an important lever for reducing the risk of obesity probably due to related sedentary behaviours and food advertising.

The place of yogurt in a healthy food environment

Yogurt has been associated with a variety of health benefit. Several studies have suggested an inverse correlation between dairy products consumption and BMI. Children who frequently consume yogurt (at least one serving per week) have a better quality diet and a better metabolic profile including a better insulin profile. Therefore, having yogurt at home could be a valuable tool to improve children’s diet and help them choose healthy food options.

Making healthy foods affordable is a challenge: nutrient-rich foods (meat, fish, dairies…) are usually more expensive than energy-dense foods (refined grains, sweets, fats…). However, yogurt is quite an exception, this healthy food provides more nutrients especially calcium and proteins than calories and is cheaper than meat, poultry or fish.  Therefore yogurt has its place in a healthy food environment: it is a nutrient-dense, affordable and accessible food.

Since home is the main place where children eat, the home food environment should provide healthy and accessible foods to children to help them make healthy food choices.

Choosing a diet that’s less harmful to the environment is one way of contributing to a healthier planet. Dietary guidance must consider environmental sustainability alongside nutrition, according to this report of the position of the Society for Nutrition Education and Behavior (SNEB) in the USA.  

When it comes to choosing what we eat, we all like to make up our own minds as far as possible. But the authors recognise that many of us would welcome some sound expert advice on how to eat in a way that doesn’t harm the world we live in. Dietary guidance that balances our health with the environment is key to pointing us in the right direction for a sustainable diet.

‘Improving the nutritional health of a population is a long-term goal that requires ensuring the long-term health of the food system as well.’ – Rose et al, 2019.

Our quest to save the planet

A sustainable diet is a pattern of eating that is good for our health, is widely available and affordable, and protects the environment for future generations.

A host of environmental issues, including climate change, loss of biodiversity (reduced variety and numbers of living organisms), land degradation, fresh water shortages and water pollution, threaten the health of our planet. These problems are caused, at least in part, by the agricultural practices that provide our food.

Advice on sustainable diets tends to focus on eating less meat and more plant-based foods. Of course, there’s more to it than this. We also need to ensure that we waste less food and that we don’t eat more than we need.

Food loss – the amount of edible food that is harvested but not eaten – is largely due to food waste especially in countries such as the USA. That’s because people frequently leave food on their plate, and food is thrown away by consumers or retailers because it looks unsightly or because it’s past its eat-by date. Such wastage not only has the environmental impact of the food produced but also causes further harm to the environment because of the disposal processes. One study showed that food losses accounted for 28% of the carbon footprint of the average US diet.

Agriculture damages the environment

Agriculture is one of the largest contributors to environmental damage. It poses a threat to the environment as it can involve:

  • clearing forests to create arable land for crops and pasture for livestock
  • a huge demand for fresh water
  • widespread water pollution due to run-off of fertilisers and pesticides from soil
  • production of greenhouse gases that are largely responsible for climate change.

To make matters worse, damage to the environment can reduce agriculture’s productivity, turning it into a vicious circle. Experts predict that up to 25% of world food production may be lost during the 21st century because of climate change, land degradation, water scarcity, and other environmental causes.

Impact of food on the environment

When we think about the harm a particular food causes to the environment, it is important to consider not only its agricultural production but also processing, packaging, transportation, preparation and cooking, and disposal of any remains.

In general, the environmental impact is higher for animal-based foods than for plant-based foods. For example, greenhouse gas emissions for the production of fruits and vegetables per kg of the food are typically less than 1 kg carbon dioxide-equivalents (putting the global warming gases – methane, nitrous oxide and carbon dioxide – on the same scale), while at the other end of the scale, beef has a value of over 30.

Is ‘organic’ best?

We may feel that organic foods are better for our health, but are they really best for the environment? Organic farming practices avoid the use of toxic chemicals and help to maintain local biodiversity and soil quality. But yields tend to be lower than for conventional agriculture, so organic farming may involve more land use.

While organically-grown grains have a lesser impact on climate change than conventional farming, organic production of some foods – such as poultry, eggs, beef, carrots and tomatoes – appears to have a greater effect on climate change than conventional production methods, research has shown.

One way in which research has suggested we could reduce the impact of our diet on the environment is by becoming ‘part-time’ meat eaters. This flexitarianism involves cutting back on animal foods and switching to a more plant-based diet but doesn’t require us to exclude any food group. Such a diet has the added advantage of improving our health.

We need advice to get it right

In our attempts to protect the environment, could we actually be doing it harm or putting our own health at risk? It is really important that well-trained nutritionists provide sound dietary advice so that people can choose a healthy sustainable diet, say the authors.

Given the serious concerns about the environment and the need to feed a growing population, SNEB recommends that environmental sustainability is an integral part of future dietary guidelines.

Future guidelines should provide specific advice, ‘…partly so that consumers will have an easier time identifying specific actions they can take to improve their own health and reduce the impact on the environment.’ – Rose et al, 2019.

As well as changing our own dietary habits, we can also achieve major advances in protecting our planet through sustainably intensifying our agriculture. This means producing more food from existing farmland with less pressure on the environment. This is exactly what’s been happening with the US diary industry, where more efficient production has cut back on the relative amounts of greenhouse gases produced. Hence a study showed that in 2007, the carbon footprint per billion kilograms of milk produced was only 37% of what it was in 1944.
