Can Lemon and Milk Be Consumed Together Without Digestive Issues? - Nutrition

Does mixing lemon with milk cause digestive discomfort?


I have gathered some information online, and many people say that lemon can be mixed with milk, but there are also many who say that milk should not be consumed with fruits containing citric acid, as it may cause the milk to curdle and increase the burden on the stomach.
Recently, I made lemon jelly and yogurt, with yogurt being made from milk.
I'm unsure whether I can drink the yogurt first and then the jelly, or if I should wait a certain amount of time before consuming the other.
How long should the interval be, or do they not affect each other and can be consumed simultaneously? Online information may not always be accurate, so I am consulting a professional.

Dear Xiao You,
Hello! Mixing lemon and milk actually has no adverse effects.
When milk encounters acidity, it undergoes a change in protein structure, known as protein denaturation, which results in the formation of curds.
This principle is also used in the production of cheese.
When milk enters the stomach, this phenomenon occurs as well, and it is further broken down and absorbed.
So, you can rest assured!
Wishing you a pleasant day!
Sincerely,

When it comes to the combination of lemon and milk, there are various opinions and beliefs surrounding their consumption together. The primary concern often revolves around the potential for digestive issues, particularly whether the acidity of lemon can cause milk to curdle and lead to discomfort. However, from a nutritional standpoint, there is no inherent danger in mixing lemon juice with milk for most individuals, provided they do not have specific allergies or intolerances.

Lemon juice is acidic, and when added to milk, it can indeed cause the proteins in the milk, particularly casein, to coagulate. This process is similar to what happens when making cheese, where an acid is used to separate the curds from the whey. While this curdling might seem unappetizing, it does not necessarily mean that the mixture is harmful or that it will cause digestive problems for everyone. In fact, many people consume lemon-flavored dairy products without any adverse effects.

For individuals with sensitive stomachs or those who are prone to digestive issues, it may be wise to consume these two ingredients separately or to allow some time between consuming lemon and milk. This is particularly relevant if you have a history of gastrointestinal discomfort after consuming dairy products. If you are considering consuming yogurt (which is made from milk) and lemon or lemon-flavored products, it is generally advisable to wait at least 30 minutes to an hour between consuming the two. This allows your stomach to process one before introducing the other, potentially reducing any risk of discomfort.

Regarding your specific question about consuming yogurt and lemon jelly (愛玉), it is also generally safe to consume them together, but again, if you have a sensitive digestive system, spacing them out may be beneficial. Yogurt contains probiotics, which can aid in digestion and may help mitigate any potential discomfort caused by the acidity of lemon.
In terms of nutritional value, both yogurt and lemon have their own health benefits. Yogurt is a good source of protein, calcium, and probiotics, which are beneficial for gut health. Lemon, on the other hand, is rich in vitamin C and antioxidants, which can support the immune system and overall health. If you were to consume lemon juice with milk or yogurt, you would still retain the nutritional benefits of both, although the curdling process may lead to some loss of texture and palatability.

In conclusion, while there is no strict prohibition against consuming lemon and milk together, individual tolerance can vary. If you or your child have experienced digestive issues in the past with dairy products, it may be prudent to consume them separately or to consult with a healthcare professional for personalized advice. Maintaining a balanced diet and being mindful of how your body reacts to different food combinations is key to ensuring digestive comfort and overall health.
