Does Making Homemade Cheese with Lemon Juice Waste Nutrients? - Nutrition

Share to:

Calcium - milk & lemon juice


If you are making cheese by adding lemon juice to boiling milk, the liquid you are discarding is called whey.
While whey does contain some nutrients, the majority of the protein and calcium are retained in the cheese itself.
However, whey is also a good source of protein, vitamins, and minerals, so you may want to consider using it in other recipes or as a drink.
Overall, while you may lose some nutrition by discarding the whey, the cheese will still provide significant nutritional benefits.

Dear Brenda: The liquid contains nutrients.
If you discard the liquid, you waste nutrition.

Making homemade cheese using lemon juice and boiling milk is a great way to introduce dairy into your child's diet, especially if he is reluctant to drink milk. However, your concern about nutrient loss when discarding the liquid, known as whey, is valid and worth discussing in detail.

When you make cheese, the process involves curdling the milk, which separates it into curds (the solid part that becomes cheese) and whey (the liquid part). The whey contains a variety of nutrients, including proteins, vitamins, and minerals. Specifically, whey is rich in lactose, B vitamins, and certain minerals like calcium and potassium. By discarding the whey, you are indeed losing some nutritional value.

Research indicates that whey protein is highly bioavailable and contains essential amino acids that are beneficial for growth and development, particularly in children. Additionally, whey has been shown to have various health benefits, including supporting muscle growth and recovery, enhancing immune function, and potentially aiding in weight management. Therefore, if you discard the whey, you are missing out on these benefits.

However, it is also important to consider the nutritional profile of the cheese itself. Cheese made from milk is a concentrated source of nutrients, particularly calcium, protein, and fat-soluble vitamins like A and D. If your goal is to increase your child's calcium intake, the cheese will provide a significant amount of this essential mineral, which is crucial for bone development, especially in growing children.

If your child is not consuming enough dairy, incorporating homemade cheese can be a beneficial strategy. You might also consider using the whey in other recipes to minimize waste. For example, whey can be added to smoothies, pancakes, or baked goods, providing additional nutrition without the need to discard it.

In summary, while making cheese does result in some nutrient loss if you discard the whey, the cheese itself remains a nutritious food option. To maximize the nutritional benefits, consider using the whey in other meals or snacks. This way, you can ensure that your child receives a well-rounded intake of nutrients, supporting his growth and development while also introducing him to new flavors and textures.
