1. Stabilizers and Thickeners
These additives improve texture but don’t add nutritional value. Some have raised concerns about potential adverse effects when consumed in excess.
- Gelatin: Generally considered safe, but it may cause problems for vegetarians and vegans since it’s derived from animal sources. There are no significant health concerns for most people unless allergic to it.
-Pectin: A soluble fibre from fruits, pectin can have a positive effect on digestion. It has been shown to help with blood sugar control and cholesterol reduction.
- Guar Gum: A natural fibre that can cause digestive discomfort in some people, especially if consumed in large quantities. It may cause bloating, gas, or diarrhoea.
- Carrageenan: Controversial, as some studies suggest it could trigger inflammation in the digestive system, though food-grade carrageenan is generally considered safe by regulatory bodies. Some people report digestive distress from it.
- Starch: Often used to thicken yogurt, it’s a common additive that’s generally safe but adds unnecessary carbohydrates and calories, which might be a concern for those monitoring their carb intake.
Health Impact:
It is neutral for most but can cause digestive discomfort in sensitive individuals, especially with carrageenan and guar gum.
2. Sweeteners
Sweeteners, both natural and artificial, are often added to flavoured yogurts and kefirs. Excessive consumption of sugar or artificial sweeteners can lead to health issues.
- Sugar (Sucrose, Glucose): Excessive sugar consumption is linked to weight gain, insulin resistance, and an increased risk of diabetes, obesity, and heart disease. Many flavoured yogurts contain high levels of added sugar.
- High-Fructose Corn Syrup: Similar to sugar but processed differently, this sweetener is associated with metabolic problems, including increased fat accumulation in the liver and a higher risk of obesity.
- Artificial Sweeteners (Aspartame, Sucralose, Saccharin): These are often used in low-calorie or "diet" versions. While they reduce calorie intake, their long-term impact on health is debated. Some studies suggest they could disrupt gut bacteria, potentially leading to metabolic issues. Others suggest links to weight gain, even though they are calorie-free.
- Stevia: A natural, plant-based sweetener considered safe, with no known negative health impacts when consumed in moderation. It’s popular for those looking for low-calorie options without artificial ingredients.
Health Impact:
-Excess sugar can lead to metabolic issues, while artificial sweeteners may alter gut microbiota or trigger cravings for sweets. Stevia and other natural sweeteners are generally safer alternatives.
Preservatives
Preservatives extend the shelf life of yogurt and kefir but are often questioned for their potential long-term effects.
- Potassium Sorbate and Sodium Benzoate: These are commonly used preservatives that inhibit microbial growth. Though considered safe in small amounts, some individuals may experience allergic reactions or headaches. In large quantities, sodium benzoate can potentially convert into benzene, a known carcinogen, when combined with vitamin C (ascorbic acid), though this is rare in dairy products.
Health Impact:
Generally safe, but large or chronic intake might pose risks for sensitive individuals or increase the chance of an allergic response.
4. Probiotic Cultures
Probiotic Cultures are usually beneficial for health, as they introduce or enhance the presence of live bacteria that promote gut health.
- Lactobacillus, Bifidobacterium, and Other Probiotics: These "good" bacteria help balance the gut microbiota, which can aid digestion, improve immunity, and reduce the risk of certain gastrointestinal issues. Probiotics are linked to overall better gut health and may also contribute to improved mood and mental health due to the gut-brain connection.
Health Impact:
Positive for most people, helping improve digestion and immune function. Some individuals may experience temporary digestive discomfort (bloating, gas) as the gut adjusts to the new bacteria.
5. Flavours and Colours
Natural flavours and colours generally have a little negative impact on health, but artificial ones might raise concerns.
- Natural Flavors: Derived from plant or animal sources, they are generally safe but add no nutritional value.
- Artificial Flavors: Although regulated, artificial flavours are synthetic chemicals, and there is limited evidence of long-term harm. However, some individuals report sensitivities to certain synthetic additives.
- Artificial Colors: Certain food dyes, like Yellow No. 5 and Red No. 40, have been linked to hyperactivity in children and allergic reactions. Some studies suggest they may also have carcinogenic potential, though these are used at levels considered safe by food safety authorities.
Health Impact:
Natural flavours and colours are generally safe, while artificial colours may cause allergic reactions or hyperactivity in sensitive individuals.
Vitamins and Minerals
Fortification of yogurt and kefir with vitamins and minerals is usually beneficial.
- Vitamin D and Calcium: Added to boost nutritional content, these are essential for bone health. Many people lack adequate vitamin D, and its fortification can help improve overall health.
Health Impact:
Positive, especially for individuals with deficiencies in vitamin D or calcium.
Multirolers: Some additives, such as maltodextrin, have multiple purposes.
Maltodextrin, a white powder made from starches, usually corn, rice, potato, or wheat, is sometimes added to commercial yogurt as a thickener, stabilizer, or filler. Although it is derived from natural sources, maltodextrin is highly processed.
Why Maltodextrin is Used in Yogurt:
Texture Improvement: Maltodextrin helps improve the texture of yogurt, making it creamier and thicker without the need for fat.
Stabilization: It helps stabilize yogurt to prevent it from separating, especially during storage or transport.
Sweetening: Maltodextrin has a mildly sweet taste, so it may be used to enhance the sweetness of yogurt without dramatically increasing the sugar content.
Volume Filler: It is also used as a bulking agent, adding volume to the product without significantly altering taste or nutritional content.
Impact of Maltodextrin on Health:
Blood Sugar Spikes: Maltodextrin has a high glycemic index, which can cause rapid spikes in blood sugar levels. This can be a concern for people with insulin resistance, diabetes, or those trying to manage their blood sugar levels.
Gut Health: There is some evidence that maltodextrin may negatively affect gut health by interfering with the balance of gut bacteria. Some studies suggest that it may encourage the growth of harmful bacteria like E. coli while suppressing the growth of beneficial bacteria.
Digestive Issues: Maltodextrin can cause digestive discomfort in some individuals, including bloating, gas, and diarrhoea. People with sensitivities or allergies to corn or wheat may also react to maltodextrin if derived from those sources.
Weight Gain: Since it’s used as a filler or bulking agent, products with maltodextrin may have hidden calories, contributing to unintentional weight gain if consumed in large amounts.
Considerations for Health-Conscious Consumers:
Minimal Processing: Yogurts that use maltodextrin are typically more processed, which may not be ideal for consumers looking for whole, natural foods.
Plain Varieties: If you want to avoid processed ingredients like maltodextrin, opting for plain, natural yogurt with minimal or no additives is a healthier choice.
Label Reading: If you are concerned about maltodextrin, it is important to check ingredient lists, especially in flavoured or low-fat yogurts, which are more likely to contain it.
Health Impact: While maltodextrin in yogurt helps with texture and stabilization, it can potentially negatively affect blood sugar levels, gut health, and overall nutrition. Choosing yogurt with fewer additives and more natural ingredients is typically better for long-term health.
Conclusion
- Minimal Additives: Yogurt and kefir with fewer or no additives are generally healthier. They contain live probiotics and simple ingredients that benefit gut health without unnecessary sugar or preservatives.
Health Risks: High amounts of sugar, artificial sweeteners, or preservatives may lead to metabolic issues, digestive discomfort, or allergic reactions. Avoiding heavily processed products might help reduce digestive issues for individuals sensitive to thickeners like carrageenan.
Opting for plain, unflavored yogurt or kefir with minimal additives is typically the healthiest choice. These can be flavoured naturally with fruits, honey, or spices at home, allowing for control over sugar content and eliminating unnecessary preservatives.
