3 things you should know about dairy

To understand how dairy foods (milk, yoghurt and cheese) affect health, consider these 3 nutrition principles:

1. Foods are much more than negative nutrients.

Yes, dairy foods are typically rich in saturated fat. But consider recent scientific research:

The health benefits of dairy, including lower and higher fat ones, makes sense: dairy foods can contain magnesium, calcium, protein, riboflavin, Vitamin B12, conjugated linoleic acid, and fermentation by-products, including probiotics, prebiotics and bioactive peptides, too.

2. Moderation in all things.

The relationship between dairy and health changes according to the amount that is consumed. Consider:

  • The relationship between cheese and heart health appears to be somewhat curvilinear, with the healthiest intake around 40 grams.
  • Large quantities of dairy may slightly increase the risk of prostate cancer.

3. There is no perfect diet.

Instead, there are many different ways to eat healthily, and no ‘best’ recommendation with regards to dairy. Consider:

  • Our body adapts according to what we eat: it has long been known that the absorption of numerous minerals is improved when their intake is low.
  • Nutrients are typically found in array of different foods, and dairy is not required for adequate calcium intake (just consume other calcium rich foods), nor is milk required for optimal bone health.
  • Dairy is not an essential food group, and the health benefits associated with its consumption can be found from eating a variety of other foods, particularly minimally processed plants.

I’ve heard advice not to eat full cream dairy (it’s high in fat!), not to eat low-fat dairy (it’s high in sugar!), not to eat cheese (it’s high in calories!), not to have cow’s milk (it’s not fermented!), and not to eat any dairy at all (it’s not natural!).

Yet my interpretation of the nutrition research is that all can be compatible with good health; yet none are essential for it.

Eat more from what you do enjoy, and enjoy more from what you do eat.

Why a calorie is not always a calorie

A calorie rich food is not always fattening, and a lower calorie food is not always less fattening. 

To demonstrate, consider these scientific findings:

  • Adding some calorie rich foods to your diet, such as nuts or olive oil, decreases waist circumference over several years.
  • Some other calorie rich foods, such as cheese, do not appear to be linked to weight gain over time. Yet some lower calorie foods, such as refined grains and potato, do.
  • Full-cream milk may actually reduce weight gain, whilst low-fat milk may not.
  • Diets high in calorie-rich foods can be better for body weight management than diets low in calorie-rich foods.

To understand this, consider the many ways a food can affect your energy balance, other than its calorie content. These include:

  • The amount of it you eat.
  • The other foods you might consume with it.
  • The foods from your diet it might displace.
  • How satisfied you feel during, and immediately after, eating it.
  • How full you feel several hours after eating it, and
  • The many ways it affects your bodies’ metabolic response, such as the resulting increase in your metabolic rate, the type and amount of hormones released to digest it, and how much your gut bacteria is fed by it.

In the short-term, weight loss is achieved by reducing calories, irrespective of food or diet.

But in the long-term, the regulation of body weight is far more complex. Some of the most calorie rich foods are among the healthiest foods that we can eat, and their consumption does not increase body weight in any way.

Much better than avoiding calorie rich foods, is to ask how you can consume more of your calories from health-promoting foods.
