Milk

In a society and age where everyone has become a nutrition guru, it’s best to always look out for and rely on strong science based articles which debunk so many pseudoscience on the internet. 

IS DAIRY REALLY THE VILLAIN? 

In a recent article in The New England Journal of Medicine, Dr. Walter Willet and some other colleagues stated thus : “A central rationale for high lifelong milk consumption has been to meet calcium requirements for bone health. Paradoxically, countries with the highest intakes of milk and calcium tend to have the highest rates of hip fractures”

Really, this is a ‘fallacious argument’- very deceptive arguments that seem convincing but lack scientific rigor. Possible truths may be found in the paper, but is there an identification of limitations? Research is not carried out based on personal bias but on neutral grounds right?

Let’s look at some potholes in this paper shall we? 

SHAKY EVIDENCE 

The paper clearly starts out by stating that there has not been any health benefits related with the HIGH intake of milk products. Well, i would like to ask this: What’s your explanation of high intake? 1 litre of milk? A  bucket of milk? Per sitting? Per month? Just state it.

We can’t deny the fact that before this new age of funny health shaky-umentaries,  there has been so much research to prove that consumption of milk and its product are beneficial to health. 

The paper even goes along to suggest that consumption of milk is related to the incidence of bone fracture through correlative data. Are you kidding me now? So many meta-analyses confirm that foods high in calcium, protein and vitamin D (especially dairy) are preventative for good bone health.

 There are obviously other sources of calcium, protein and vitamin D that are healthy and beneficial, but demonising  a particular food group just to push the vegan agenda doesn’t alright. 

Before stating the correlation of a data, so many things like vitamin D status, genetics, longevity, exercise, environmental factors, or overall diet quality should be considered – because a lot more goes into building strong bones than simply calcium.

“Aside from bone fracture risk, the authors also look at how dairy consumption links to cardiovascular disease. They state that milk is beneficial to the heart when being used as a substitute for sugary beverages (like pop or juice) and then state that milk isn’t beneficial if it replaces whole fruit, nuts, and legumes in the diet” My question is – Why do you think milk is replacing those other foods? What do you term an adequate diet?

Isn’t it one that has all food groups in right proportions and quantities?

IS THERE A ROOM FOR DAIRY INTOLERANCE?

Dairy has never posed any health problems as claimed by everyone on the internet, but really, there are some individuals that won’t be able to tolerate dairy products.

Many people are lactose intolerant (carbohydrates found in dairy) and have serious digestive problems when they consume dairy products. So it’s best they eliminate dairy products from their diets so they won’t have complications.

Some folks are also allergic to cows milk which could lead to hives, skin rash and anaphylaxis. But hey, these people are not the ALL people yes?

Dr Willet also stated that 67% of children with diagnosed intolerance to cow’s milk had reduced symptoms immediately they were switched to an alternative- soy milk (plant based). OH YES! They sure will since they were given an alternative to cow’s milk which don’t contain lactose. But really, the agenda was to kick against the consumption of cow’s milk.

If you feel better and don’t get digestive problems when you eliminate milk from your diet, no problems. But doing it out of fear? We dietitians won’t support that.

MILK AND MUCUS PRODUCTION 

The texture of any fluid determines the texture and amount of mucus produced after consumption of said fluid. 

Mucus is produced by cells within the nose, sinuses and lungs.  It consists of water, salt and various proteins that help trap germs and particles of dirt.

“There is a belief among some members of the public that the consumption of milk and dairy products increases the production of mucus in the respiratory system. Therefore, some who believe in this effect renounce drinking milk. According to Australian studies, subjects perceived some parameters of mucus production to change after consumption of milk and soy-based beverages, but these effects were not specific to cows’ milk because the soy-based milk drink with similar sensory characteristics produced the same changes. In individuals inoculated with the common cold virus, milk intake was not associated with increased nasal secretions, symptoms of cough, nose symptoms or congestion. Nevertheless, individuals who believe in the mucus and milk theory report more respiratory symptoms after drinking milk. In some types of alternative medicine, people with bronchial asthma, a chronic inflammatory disease of the lower respiratory tract, are advised not to eat so-called mucus-forming foods, especially all kinds of dairy products. According to different investigations the consumption of milk does not seem to exacerbate the symptoms of asthma and a relationship between milk consumption and the occurrence of asthma cannot be established. However, there are a few cases documented in which people with a cow’s milk allergy presented with asthma-like symptoms”. 

That being stated, lets focus on the benefits of dairy products 

BENEFITS OF DAIRY PRODUCTS 

Dairy products like milk, yogurt, cheese, and cottage cheese, are good sources of calcium, vitamin D and protein which helps maintain bone density and reduces the risk of fractures. Adults up to age 50 need 1,000 milligrams (mg) of calcium per day. Women older than 50 and men older than 70 need 1,200 mg. (For comparison, a cup of milk has 250 mg to 350 mg of calcium, depending on the brand and whether it’s whole, low-fat, or nonfat. A typical serving of yogurt (plain) has about 187 mg of calcium.) Milk is also fortified with vitamin D, which bones need to maintain bone mass.

WHICH DAIRY IS PREFERRABLE?

The American Heart Association still recommends adults stick to fat-free or low-fat dairy products. But new research suggests full-fat dairy might not be much of a threat to heart health. A report presented at the 2018 Congress of the European Society of Cardiology looked at 20 studies involving almost 25,000 people, and found no association between the consumption of most dairy products and cardiovascular disease.

Some science has even suggested that the right kind of dairy may prevent heart disease. A study involving 2,000 men published by the British Journal of Nutrition found that those who ate plenty of fermented dairy products like yogurt and cheese had a smaller risk of coronary artery disease than men who ate less of these products. This supports earlier studies that showed that fermented dairy products have more healthful effects on blood lipid profiles and the risk of heart disease than other dairy products.

 

BOTTOM LINE 

On the issues of overall health benefits, dairy products {especially milk) are neither poison or potion. The right quantity added to your daily diet is important in benefiting from vital nutrients for every day activities and function. 

 An adequate diet cannot be over emphasized; elimination or demonising food groups won’t solve any problems.

DIETARY GUIDELINES FOR AMERICANS (2015-2020)

Dietary guidelines simply mean a guide for a healthy diet. These guidelines for healthy eating were put forth by the United States Department of Agriculture (USDA) and are revised every five years (most recent being 2015-2020) to form and evaluate nutrition programs and policies. It is used as a tool to form federal food, nutrition and health policies as well as serves as a guide for professionals and the America public make healthy food choices. They reflect the importance of creating healthy eating habits in order to improve nutrition status, overall wellbeing and reduce risk of disease.  Let’s delve right n then!

Dietary Guidelines for GRAINS:

At some point we all take grains either refined or whole! Replacing refined grains with whole grains is healthier and here is why. Refined grains contain just the endosperm which contains starch and protein, very well, but the whole grains consist of the bran (rich in fiber and nutrients), endosperm and germ (rich in vitamins and minerals), so much for refinement.

Selecting at least 6 ounces of grains with at least half of these (3 oz) whole would ensure a healthy contribution of nutrients such as essential B-Vitamins, iron, folate and fiber to the daily diet.  Some examples of whole grains include brown rice, millet, oats, buckwheat, whole wheat products, barley and so forth. Conversely, examples of refined grains include white rice and refined grain products.

Refined grain products include but are not limited to biscuits, cakes, cookies, cornbread, crackers, pastries and granola. However, in the early 1940’s congress passed legislation requiring that all grains passing state lines be enriched with iron, thiamin, riboflavin and niacin.

Further down the line in 1996, this legislation was amended to include folate, an essential vitamin to preventing birth defects. This means we can now get these much talked about nutrients in whole grain, fortified cereals. Isn’t that marvelous?!

 Dietary Guidelines for FRUITS AND VEGETABLES:

These are no new comers to such lists. Everybody has heard at some point the phrase “eat your vegetables!”. Well, we are still gonna ask you to eat them, but this time we-d tell you why you should.

Fruits contain a valuable amount of minerals, vitamins, nutrient and PHYTOCHEMIALS. I am emphasizing on photochemical because I see a lot of people consume just one particular type of fruit example, apples and then claim to eat a lot of a fruits which by that means plenty apples, hahaha. But literally the person just gets a particular set of nutrients from apple in contrast to a person that takes a variety of types and color, gets varieties of nutrient. Phytochemicals are chemical contents o fruits and vegetables that give them their characteristic color.

Asides color, these bioactive components have the potential to reduce risk of various chronic diseases such as cancer, cardiovascular diseases, obesity among others. These different colors connote different phytochemicals which confer different benefits. So let us do more of fruit variety (too many fruits in the grocery store to try out) than stick to a particular one.

The USDA has set a serving of vegetables at 2 cups and fruits at 2 ½ cups per day. Choosing fresh, green leafy vegetables ensures you get unadulterated vitamins as wet boiling or steaming of vegetables cause nutrients to leach into the water and subsequently lost. Also, limit vegetables that contain solid fats or added sugars such as baked beans, candied sweet potatoes, French fries, refried beans, coleslaw and French fries.

Still on the issue of VEGETABLES, dressings and ranches could work against a person trying to eat healthy by contributing unnecessary sodium and calories to the diet. To this end, we suggest healthy choices such as olive oil dressing. Another helpful option could include stir frying the vegetables in healthy vegetable oil, such as olive oil or canola oil with some garlic, ginger or onions. Yummy! Guess what I’m having for supper?

Dietary Guidelines for MILK AND MILK PRODUCTS:

I am guilty of this *covers face*. I love love love whole milk; I mean who wouldn’t? but it is not the very best. It is advised to replace whole milk products with fat-free or low fat options (preferably 1%). Milk is rich in calcium, riboflavin, niacin, vitamin B12, calcium, potassium and when fortified, vitamins A and D.

If you do not consume milk, please choose products rich in calcium and vitamin D. Limit intake of milk products that contain added sugars and are high in fat such as whole milk and whole milk products such as cheeses, cottage cheese and whole milk yoghurt (do Greek yogurt instead), 2% reduced fat milk, ice cream, whole fat chocolate milk, custard, milk shakes, pudding and sherbets. The current recommended daily amount for milk lies at 3 cups per day.

Since milk products are important source of calcium and some are fortified with vitamin A & D, we might as well choose the fat free ones thereby helping ourselves eat healthy and also getting the nutrients we need.

 

Dietary Guidelines for PROTEIN:

Protein foods which include seafood, poultry, eggs, legumes, soy products, nuts and seeds as well as beef and pork not only provide proteins but also B vitamins, vitamin E, iron, zinc and magnesium.

It is advised by the DGA to take a variety of these foods, not just only poultry because that’s some people idea of protein. Varieties of proteins include; lean meat, eggs, legumes, unsalted nuts and seeds, soy products and poultry. These foods provide vitamins B & E, Zinc, iron and Magnesium. We must also know that we could consume these foods in an unhealthy way by adding too much fat and sodium, so we really need to be careful when cooking them.

To keep fat intake low, bake, roast, grill or braise meats, poultry and seafood but avoid frying them in fat. For example try not to fry your poultry and sea foods in fat, drain all visible fat after cooking and peel poultry skin off to reduce fat content.

For the nuts; I know we are always tempted to buy/eat salted nuts which increase the intake of sodium, so let us make better choices which include unsalted nuts and unfried nuts. Because nuts and seeds are energy dense, it is advised that they be consumed in little quantities and in place of, not in addition to other,, high protein and fat foods such as beef and pork.

Limit protein foods that contain solid fats such as bacon, pork, beef, fried mat, marbled steak, poultry with skin and ggs. The current RDA for proteins is 5 ½ oz per day based on a 2000 Kcal diet.

 

Some Tips for Vegetarians:

Lacto-ovo-vegetarians who eat animal-derived foods such as milk and eggs receive high quality protein and are more likely to meet their protein RDA. A well planned vegetarian diet helps to ensure adequate intake of nutrients such as protein, iron, vitamin B₁₂, vitamin D and Omega-3 fatty acids. All it takes is adequate knowledge and proper planning with a nutritionist. *wink*
