Dairy-based diets are those that include milk and milk products, such as cheese, yoghurt, and butter. Dairy is a valuable source of nutrients, including calcium, protein, and vitamins B12 and D, which are important for bone health. However, some people choose to follow a dairy-free diet due to lactose intolerance, allergies, or ethical reasons. Dairy-free diets can offer benefits such as improved digestive health, weight management, and reduced acne, but it is important to replace the nutrients typically provided by dairy, such as calcium and vitamin D, to avoid deficiencies. Alternatives to dairy include soy, almond, coconut, and oat milk, which may be fortified with calcium and other nutrients.

What You'll Learn
Dairy is a good source of calcium, protein, and vitamins
Dairy products are a great source of calcium, protein, and vitamins. Dairy foods like milk, cheese, and yogurt provide a powerful nutrient package that contributes to a healthy body. Dairy is one of the five food groups in the USDA's MyPlate dietary guidelines.
Milk, cheese, and yogurt are excellent sources of protein and calcium. They can form part of a healthy, balanced diet. However, they can be high in saturated fat, so it's important to make healthy choices. For example, opting for low-fat or fat-free dairy products can help reduce the intake of saturated fat. Dairy products are also a good source of vitamin D, which helps the body maintain proper levels of calcium and phosphorus, supporting bone health.
Vitamin D is considered a "nutrient of concern" as many US adults do not get enough of it daily. Fortified milk and yogurt with added vitamin D can help increase intake of this vital nutrient. Additionally, milk is a good source of vitamin A, vitamin B12, and riboflavin. Yogurt is also rich in probiotics, which promote immune function, improve heart health, and enhance nutrient absorption.
Dairy alternatives, such as unsweetened calcium-fortified plant-based milks, can be a good option for those who do not consume dairy. However, it is important to note that the amount of calcium absorbed from these alternatives may vary.
Overall, dairy is a good source of calcium, protein, and vitamins, offering various health benefits when consumed as part of a balanced diet.

Lactose intolerance and allergies are reasons to avoid dairy
Dairy products are a good source of nutrients and form part of a healthy, balanced diet for many people. However, some individuals may need to avoid dairy due to lactose intolerance or dairy allergies. Lactose intolerance is a common digestive issue caused by the body's inability to produce enough lactase, an enzyme required to digest lactose, a sugar found in milk and dairy products. While lactose intolerance can cause discomfort, it is not life-threatening. Symptoms include nausea, cramps, gas, bloating, and diarrhoea. Lactose intolerance is more prevalent in adults and certain ethnic groups, including those of Asian, African, or Native American heritage.
On the other hand, a dairy allergy is an immune system response to the proteins in milk and dairy products. Allergies can cause a range of symptoms, from mild to severe, and can even lead to life-threatening anaphylaxis. Dairy allergy is one of the most common allergies, especially in infants and young children. About 2.5% of children under three years old are allergic to milk, and it often develops when cow's milk is introduced into their diet. Symptoms of a dairy allergy may include skin and lung issues, such as eczema, throat swelling, and trouble breathing.
Both lactose intolerance and dairy allergies can cause similar symptoms, such as digestive problems, but it is essential to distinguish between the two conditions. Doctors can perform tests, such as lactose tolerance tests, hydrogen breath tests, and skin prick tests, to determine the specific condition. While lactose intolerance is more common in adults, anyone can develop a dairy allergy, especially if they have other allergies or a family history of allergies.
Managing lactose intolerance and dairy allergies involves dietary adjustments. Lactose-intolerant individuals can opt for lactose-free dairy products that contain added lactase to aid digestion. Those with dairy allergies must be cautious about their food choices and may need to carry injectable epinephrine to manage severe allergic reactions. Additionally, individuals with either condition should ensure their diet includes other sources of calcium and vitamin D to maintain adequate nutrient intake.
In summary, lactose intolerance and dairy allergies are valid reasons to avoid dairy products. While dairy provides essential nutrients, individuals with these conditions can manage their symptoms and maintain their health by making careful dietary choices and consulting with healthcare professionals.

Dairy-free diets can help with weight loss and management
Dairy-free diets have become increasingly popular, with many people adopting them for health and weight management reasons. While dairy products are a good source of protein and calcium, they can also be high in saturated fat and sugar, which can contribute to weight gain. Thus, cutting out dairy may be beneficial for weight loss and management.
Dairy products, such as milk, cheese, and yoghurt, are nutrient-dense, providing calcium, protein, and vitamins B12 and D. However, for people with lactose intolerance or milk allergies, consuming dairy can lead to adverse symptoms like bloating, diarrhoea, and acne. Additionally, those with inflammatory bowel disease (IBD) may experience inflammation and digestive issues when consuming dairy due to their difficulty in digesting lactose. As a result, a dairy-free diet can help manage these conditions and alleviate associated symptoms.
Full-fat dairy products, in particular, are high in sugar and saturated fat. Consuming excessive amounts of these nutrients can lead to increased calorie intake, which contributes to weight gain. By eliminating dairy, individuals can reduce their overall calorie intake, which is a fundamental aspect of weight loss and management. This is especially true for heavy dairy consumers, who may experience significant calorie reduction by switching to dairy-free alternatives.
However, it is important to note that dairy alternatives may not always be healthier or lower in calories. Replacing dairy with plant-based options like soy, rice, oat, or almond milk can help manage calcium and vitamin D intake, but these alternatives may not offer the same protein content as dairy. Additionally, some dairy alternatives can be high in sugar and saturated fat, negating the potential weight loss benefits.
While cutting out dairy may aid in weight loss and management, it is essential to consult a healthcare provider before making any significant dietary changes. This is especially crucial for those with allergies or lactose intolerance, as they can advise on nutrient replacement to ensure a well-rounded and healthy diet. Overall, while dairy-free diets may assist in weight management, a balanced approach to nutrition and calorie intake is key to maintaining a healthy weight.

Dairy-free diets may cause nutrient deficiencies
Dairy-based diets are one of the five food groups in the USDA's MyPlate guidelines. Dairy products like milk, yogurt, cheese, and lactose-free milk are included in this group, providing essential nutrients like calcium, protein, and vitamins.
However, some people choose to follow dairy-free diets due to lactose intolerance, allergies, weight management, or ethical reasons. While dairy-free diets can offer benefits like improved digestive health and reduced allergies, they may also lead to nutrient deficiencies.
The main nutrients that may be lacking in a dairy-free diet include:
Calcium
Calcium is crucial for bone development and maintenance of bone structure throughout life. Dairy products are a significant source of calcium, and while calcium is available from non-dairy sources like leafy greens, seeds, nuts, and fortified foods/drinks, the amount of calcium absorbed from these alternatives may vary. Fortified soy milk and yogurt, as well as lactose-free milk, can be good sources of calcium for those avoiding dairy.
Protein
Protein is essential for muscle growth and repair, and dairy products are a primary source of protein in the average diet. While adults may not need to make a special effort to replace dairy proteins, it can be more concerning for teenagers and the elderly. Non-dairy sources of protein include fish, red meat, poultry, eggs, beans, pulses, and vegan protein powders.
Vitamin D
Vitamin D helps maintain calcium levels and bone health. Dairy products are often fortified with vitamin D, so removing them from the diet may lead to a deficiency. Vitamin D can be obtained from non-dairy sources like fatty fish, eggs, and fortified foods.
Iodine
Iodine is essential for fetal brain development and cognitive function in children. Dairy milk is a good source of iodine, providing around 70 micrograms per glass. Non-dairy milk alternatives may be too low in iodine, and other sources like eggs and seafood may be needed to meet recommended intakes.
Other Minerals
Dairy-free diets may also result in deficiencies of minerals like zinc, phosphorus, and potassium. These minerals are important for various bodily functions, including bone health, metabolism, and maintaining healthy blood pressure. A variety of non-dairy foods can provide these minerals, including leafy greens, nuts, and fortified gluten-free products.
