Artificial sweeteners in breast milk can cause vomiting in infants
Artificial sweeteners are calorie-free chemical substances used to sweeten food and drinks instead of sugar. They are often recommended to pregnant women with obesity or diabetes to prevent an increase in body weight. However, there is some controversy surrounding artificial sweeteners and concerns about the risk of obesity caused by metabolic changes, both in the mother and the child.
Artificial sweeteners such as acesulfame, saccharin, and sucralose have been found in breast milk after maternal ingestion. These sweeteners are found in products such as sports drinks, low-carb snacks, and low-sugar chocolate bars. They are also often consumed via sweetener packets or diet beverages.
While artificial sweeteners are considered safe for use during pregnancy and lactation, there is limited data on their potential effects on infants. Studies have shown that these sweeteners can be detected in the breast milk of lactating women several hours after oral ingestion, and they can also be found in the plasma. The time for peak concentration was between 30-120 minutes in plasma and 240-300 minutes in breast milk.
Although the risk to breastfed infants appears to be low, there are potential adverse effects on the infant's gut microbiome and future food choices. Rodent studies have shown that exposure to artificial sweeteners during lactation may promote the development of metabolic abnormalities and obesity in adulthood. However, similar studies have not been conducted on humans.
While artificial sweeteners in breast milk have not been directly linked to vomiting in infants, they can cause digestive issues and alterations in the gut microbiome, which could potentially lead to vomiting. It is important for nursing mothers to be aware of their sweetener intake and consult with healthcare professionals to ensure the safety and well-being of their infants.

Maternal consumption of sweeteners can increase an infant's risk of obesity
Artificial sweeteners are calorie-free chemical substances used to sweeten food and drinks instead of sugar. They are often recommended to pregnant women with obesity or diabetes to prevent an increase in body weight. However, there is some controversy surrounding their use due to concerns about the risk of obesity caused by metabolic changes in both the mother and the baby.
Maternal consumption of sweeteners during pregnancy has been associated with an increased risk of obesity in infants. Animal studies have suggested that exposure to artificial sweeteners in utero may predispose offspring to obesity. For example, a study on pregnant rats found that the consumption of sweeteners during pregnancy resulted in offspring with a higher body fat percentage. While similar studies have not been conducted on humans, there is some evidence that maternal consumption of artificial sweeteners during pregnancy may influence infant body mass index (BMI). In a study of 3033 mother-infant pairs, daily consumption of artificially sweetened beverages during pregnancy was associated with a higher infant BMI z score and a 2-fold increased risk of infant overweight at one year of age.
Additionally, certain artificial sweeteners have been detected in breast milk after maternal ingestion. These include saccharin, sucralose, acesulfame-potassium, and cyclamate. While some of these sweeteners are considered safe for use during pregnancy and lactation, there is limited data on their potential effects on infants. For example, sucralose is reportedly poorly absorbed after oral ingestion and is therefore unlikely to reach the infant's bloodstream or cause adverse effects. However, other studies have found a link between early exposure to non-nutritive sweeteners and an increased risk of obesity in infants. Rodent studies have shown that animals exposed to acesulfame-potassium in utero or through breastfeeding exhibited a heightened preference for caloric sweeteners and non-nutritive sweeteners in adulthood.
Overall, while artificial sweeteners may be a helpful tool for weight management in pregnant women, more research is needed to fully understand their potential effects on infant health and development. In the meantime, it may be advisable for pregnant and lactating women to limit their consumption of artificial sweeteners and opt for fresh, unprocessed foods to reduce the potential risk of obesity in their infants.

Sweeteners can be transferred to plasma and then to breast milk
Artificial sweeteners are calorie-free chemical substances used to sweeten food and drinks instead of sugar. They are often recommended to pregnant women with obesity or diabetes to prevent an increase in body weight. However, there is some controversy surrounding their use due to concerns about the risk of obesity caused by metabolic changes, both in the mother and the child.
Several studies have been conducted to investigate the presence of artificial sweeteners in breast milk. One such study involved providing 49 lactating women with a beverage containing four different artificial sweeteners: acesulfame-potassium, saccharin, cyclamate, and sucralose. Blood and breast milk samples were collected before and up to six hours after consumption. The results revealed that all four artificial sweeteners were transferred to plasma and then to breast milk in lactating women. The time for peak concentration was between 30–120 minutes in plasma and 240–300 minutes in breast milk.
It is important to note that the quantity of sweeteners in the beverage used in this study exceeded the regular amount found in light products. To reach the offspring's acceptable daily intake (ADI) dose through breast milk, a woman would need to consume between 14 and 5444 beverages. Despite this, the study found that very large amounts of the sweeteners were required to reach the maximum daily intake (ADI) in both the mother and the offspring.
While acesulfame-potassium, saccharin, and sucralose have been detected in breast milk, aspartame is not detectable. This is because aspartame is rapidly broken down in the mother's body and is not present in quantifiable levels in breast milk. However, it is recommended that mothers avoid aspartame when nursing an infant with phenylketonuria, as it can increase the levels of phenylalanine in breast milk.

Fructose in breast milk is associated with a 5-10% increase in body weight and body fat for infants at 6 months
The presence of sweeteners in breast milk is a cause for concern for many mothers. While some sweeteners are considered safe for use during pregnancy and lactation, others may have adverse effects on the infant. For example, the presence of saccharin, sucralose, and acesulfame-potassium (Ace-K) in breast milk has been confirmed, while aspartame has not been detected. These artificial sweeteners are known to have the potential to influence the infant's gut microbiome and impact future food choices and dietary patterns.
Fructose, a natural sweetener, has been detected in breast milk, and its presence is associated with infant body composition at six months of age. Despite its very low concentration in breast milk, about 1/30th the level of glucose, fructose levels are biologically relevant. Each 1-μg/mL increase in fructose was associated with a 5-10% increase in body weight and body fat for infants at six months. Specifically, a 1-μg/mL higher breast milk fructose concentration was associated with a 257 g higher body weight, a 170 g higher lean mass, a 131 g higher fat mass, and a 5 g higher bone mineral content.
The mechanism behind this association may be related to the influence of fructose on the infant's metabolism and insulin resistance. Additionally, the presence of sweeteners in breast milk may predispose infants to a higher risk of increased sugar intake and obesity later in life. However, it is important to note that these findings are based on studies with limitations, such as small sample sizes and inconsistent designs and findings.
While the exact cause of this association is still being investigated, it highlights the importance of maternal dietary choices during lactation and their potential impact on infant health and development. Further research is needed to fully understand the effects of sweeteners in breast milk and to develop guidelines to minimize any potential negative consequences.

Aspartame is not detectable in breast milk but should be avoided when nursing an infant with phenylketonuria
Aspartame is an artificial sweetener commonly found in diet sodas and sweetener packets. It is a popular nonnutritive sweetener (NNS) that is used by many as a sugar substitute. Aspartame is rapidly broken down in the mother's body, and therefore it is not detectable in breast milk. However, it is recommended that mothers avoid consuming aspartame while nursing an infant with phenylketonuria (PKU).
Phenylketonuria is an inherited disorder that affects the levels of phenylalanine, a protein building block (amino acid), in the blood. This disorder is caused by variants in the PAH gene, which provides instructions for making the enzyme phenylalanine hydroxylase. This enzyme is responsible for converting phenylalanine into other important compounds in the body. When the PAH gene is altered, the enzyme it produces cannot effectively process phenylalanine, leading to a buildup in the blood and other tissues. Untreated PKU can result in harmful levels of phenylalanine, causing intellectual disability, seizures, delayed development, behavioural problems, and psychiatric disorders.
When aspartame is consumed, it is metabolized into aspartic acid and phenylalanine. While aspartame itself is not detectable in breast milk, the increased levels of phenylalanine resulting from its consumption can be present in the breast milk of nursing mothers. This can pose a risk to infants with PKU, as they are already unable to process phenylalanine effectively. Therefore, to avoid any potential harm, mothers are advised to refrain from consuming aspartame when nursing infants with this condition.
It is important to note that the presence of aspartame in breast milk has been extensively studied, with researchers conducting randomized controlled trials and collecting breast milk samples from lactating women. These studies have consistently found no detectable levels of aspartame in breast milk after maternal ingestion. However, it is worth mentioning that an extremely large intake of aspartame, equivalent to approximately 17 cans of soda or 100 packets of sweetener, can slightly increase the amount of phenylalanine in breast milk. Nonetheless, these elevated levels of phenylalanine return to baseline within 12 hours after a single large dose of aspartame.
In summary, while aspartame is not detectable in breast milk, it is recommended that mothers avoid its consumption when nursing infants with phenylketonuria due to the potential impact on phenylalanine levels.
