Over the years I have concluded that there is no benefit from consuming dairy for the body in any shape or form. I do however believe it depends on the individual as to what level he/she is affected by consuming dairy. For example, the lifestyle each individual has, the level of stress, current diet, if dairy was consumed at a younger age, how much is consumed in their current diet.
Studies have shown that by consuming dairy in the form of milk depletes calcium from the bones as animal protein produces acid which leaches calcium from the bones. A medical study showed that people that consume the most amount of cows milk has significantly higher fracture rates to a person that does not consume any or as much dairy.
Milk and cheese have been linked to increased risk of developing prostate cancer, ovarian cancer, increased and development of acne in boys and girls, weight gain, stomach difficulties due to build up of bacteria in the gut as antibiotics are added to cows feed which we consume and are causing more health implications.
People are gaining more milk allergies and are becoming lactose intolerant which causes health difficulties, concerns and problems. So it is important to get tested to check this from a medical doctor who has the nutritional background, through a blood sample, on an ongoing basis.
A single serve of whole milk contains more than 20% of the RDA of saturated fat. Cheese is the worst for weight gain and this needs to be monitored.
Humans are the only animal outside the animal kingdom that consume dairy. Calves have 4 stomachs not 1 so it is needed by a calf to aid development not people, in my opinion. Calves also need to gain weight more rapidly.
In my professional experience, symptoms vary from each person. If a client tends to gain more weight, suffers from acne, stomach problems, etc., they will react more, so it is vital they don't consume dairy. Others do not seem to react to the same severity, however, I do feel within my experience of consulting, you will see the signs of reacting negatively in some shape or form with each individual.
I would refrain from using dairy because of how it can make you feel and the difficulty of the enzymes to break down in your body can lead to more health complications throughout someone's life.
The alternative I use and would recommend is oat, coconut, almond and rice milk depending on the needs of the individual.
