Healthy Diet: Milk Bioactives Protect Against Disease

A consequence of the obesity epidemic, which began in the United States during the 1980s, is the targeting of milk as a possible contributing factor for weight gain, metabolic syndrome, and cardiovascular disease, due to its high fat content. As a result, in the mid 1990’s, the U.S. Department of Agriculture recommended switching to reduced-fat milk, and the consumption of whole milk fell drastically. As this was happening, the growth of soy and soy “milk” paved the way for other milk-alternative beverages, such as, almond, coconut, and cashew “milk”, and consumers began to question whether it was healthy or natural for human to consume animal milk at all. In addition to fears that milk milkcontributed to obesity, and the metabolic disorders that go along with excessive weight gain, milk allergy, and anecdotal reports of milk worsening rhinitis, and triggering asthma began to surface.

However, in the past decade, several studies have reported beneficial health effects of cow’s milk in the prevention of the development of asthma and allergy in children, as well as, protection against cancer, obesity, diabetes, and cardiovascular disease in adults.

Further investigation into the composition of milk, and its components haves revealed that it may be time to reconsider the health benefits of milk again. In addition to its nutritional value, the ingredients in milk possess bioactive functionality. The protein, lipid, and saccharide components of milk contain molecules that are anti-inflammatory, anti-microbial, and immunogenic (capable of modulating the immune system), in addition to improving the body’s response to insulin and regulation of fat.

Healthy Diet: What Really Causes Cardiovascular Disease

Americans are increasingly concerned with eating healthy. Over the past two decades, there has been a myriad of changes in the public’s perception of what is and isn’t healthy. Initially, it was generally agreed upon and understood that a diet consisting mainly of greasy food and too much sweets was unhealthy. However, the consensus on what foods are to be considered healthy versus harmful has become complex and the subject of much debate. For instance, it was once considered unhealthy to eat eggs, though the medical consensus has changed— it turns out that eggs are not as high in cholesterol as once thought—many people still maintain that the yolks should be removed, and that egg whites are healthier.

Much of the focus on health has revolved around a single nutrient, food, or food group. For example, whole wheat  became preferred over bleached flour, then eventually, eating any wheat at all became controversial and wheat-free diets were promoted. The same happened with rice: white rice gave way to brown rice, which then gave way to quinoa. Super foods like soy, kale, and chia seeds became popular, along with fad diets, like the Atkins diet which emphasized low carbohydrate intake, and the Southbeach diet. Most recently,  health gurus promoted health concepts which lead to the  alkaline diet, out of which came alkaline water. Now, sensationalized documentaries are leading people to abandon meat and dairy all together.

As a result, many are unfortunately left confounded when it comes to what they should or should not eat. There is much fear surrounding food safety and health, due impart to a lack of understanding of nutritional requirements and technological advancements in food production, leaving many weary that meat and dairy, in particular, can lead to the development of Cardiovascular disease and Type 2 Diabetes. However, focusing on the beneficial effects of a single nutrient, food, or food group does not comprise a healthy diet. What is more important is dietary pattern; the amounts, frequency, and variety of nutrients and foods that are consumed habitually, coupled with other lifestyle factors, are the greatest determinants in the association of diet and health, as Cardiovascular Disease and Diabetes are consequences of leading a sedentary lifestyle while being overweight or obese.
