Are you mindful of magnesium?

Vitamin D, omega 3’s are the nutrients du jour but these usurped calcium and Vitamin E. You know how it goes and many of you have the old supplement bottles demonstrating these shifts. Few things bug me more than the nutrition pendulum and often the pendulum completely misses the food, vitamin or mineral I feel we should focus on (clearly I don’t write the headlines). In this case, I’m wondering why we’re not mindful of magnesium?

Magnesium is a mineral present in food and the body. Magnesium is required for muscle contraction (a reminder the heart is a muscle), nerve function and magnesium plays a role in blood pressure and bone health. So it’s important. The key issue though is that under mental or physical stress cells release magnesium and it is excreted, bye bye precious magnesium. If stress is chronic or extreme you may be deficient in magnesium.

 Low magnesium can affect GI function ("going"), exercise recovery and PMS-related mood changes. In one study, after a month of magnesium supplementation participants were found to have decreased PMS and improved mood as shown via their  “Menstrual Distress Questionnaire scores”. Oh my goodness, my family would give me such poor menstrual distress scores. Magnesium is also required for metabolic reactions such as the metabolism of carbs and fats to produce energy. Magnesium is  important for athletes as low magnesium levels result in higher heart rates during exertion. 

Most people don’t consume enough magnesium. Once again, seeds are significant pumpkin, hemp (pictured above) and sesame top the list. Spinach, cacao and lentils and black beans are also good. I also love a powdered magnesium supplement called Natural Calm I take at bedtime.

         

Unfortunately, testing to see if magnesium is low isn’t all that helpful. A low percentage of magnesium is found in blood. I think the better bet is to put magnesium-rich foods front and center (1 seed a day) during your day and consider a modest amount of supplementation. That is if your bones, blood pressure, mood or bowel function matters to you.

Is magnesium on your radar? Do you supplement magnesium? If so why did you start taking it? Any “menstrual distress”? 

Dairy: decrease or desist?

From Refinery29 article, link below

I was recently consulted for a Refinery29 article “No Whey: What Milk Really Does To Your Bod”. Dairy baffles many people that I thought I would review the dairy details.

Dairy Hierarchy

Not all dairy is the same. In any food category whether it’s carbs or soy sometimes you can tolerate or benefit from certain types versus others.  You probably know I’m anti skim milk; non-skim, fermented, organic dairy is very different from conventional, skimmed, subpar stuff. It’s important to be discriminatory with your dairy.

Fermented dairy is easier to digest and fermented foods can benefit you well beyond your immune system. Unlike Vegas, what happens in your gut doesn’t stay in your gut and probiotic foods have far reaching effects from your weight to your mood.

Additionally, goat and sheep dairy is often better tolerated. Anti dairy folks often point out that it’s unnatural for us to drink another animal’s milk.  In the case of goat and sheep’s milk it’s actually most similar to human breast milk in its makeup (I can’t decide if knowing this makes it more or less appealing). While lactose slightly lower in goat or sheep versus cow it’s really the casein content that makes the difference. Furthermore there are higher levels of MCTs (same type of fats in coconut milk) in goat and sheep versus cow milk. There’s a great sheep’s milk company called Old Chatham. Their ginger yogurt is amazing.

And unless you find antibiotics, added hormones and inferior nutrition appealing…if nothing else all dairy you purchase should be organic. You can make the argument that you can wash (not that this makes it pesticide free) an apple; you can’t wash your yogurt. A study on 3^rd graders in another country showed their hormone levels soared after a month on US, conventional milk, enough said.

Pro Dairy

A case can be made that dairy helps with PMS symptoms (do you recall the California Milk Board’s ad geared toward men “living with PMS”? oy those caused a little bit of a backlash). Full fat dairy is associated with less fat around the waist or midsection, decreased likelihood of insulin resistance and type 2 diabetes. This is due to a fatty acid called palmitoleic. I expect we’ll be hearing more about this. And men who strength train may be able to get more muscular with dairy in their diets.

Dairy Drawbacks

If you look up the important research from Dr Davaasambu (what a name), you will see studies linking milk consumption to a host of cancers. The proposed reasoning is that cows are being milked more days per year, often when pregnant when levels of certain hormones are higher.

In terms of digestion, while many point to lactose as a source of tummy troubles, there’s another potential covert culprit and that’s casein. Casein is a protein in milk (I mentioned it earlier with sheep/goat dairy) that many people, especially those who have problems with gluten, do not do well with.

If a client presents with sinus symptoms and allergies or certain skin conditions, I consider advising them to experiment with ditching dairy.

Bones When it comes to bone health, if you’re only keyed in on calcium you’re missing the “bone” boat. We need calcium but it doesn’t have to come from dairy think about sardines, greens and beans. Having enough Vitamin D seems to be way more important than supplementing calcium. Additionally there’s magnesium sort of a sly player in the osteoporosis game.

Alternatives

There are a host of “alternative” milks from almond to cashew to coconut and nut milk is very easy to make (and delicious).If you choose to purchase nut milk make sure there’s no carrageenan in the ingredient list. In NYC, OMilk makes fantastic small-batch nut milks in fun flavors.

I think it’s important to think about your diet, your goals and consider whether you need dairy and how much; there’s certainly no need to overload on it.  It’s no coincidence that as I googled dairy MyPlate and Dairy Counsels etc. came up. There’s this conventional “wisdom” or belief that we need lots of dairy to be a healthy and further that we should look for fat free and low fat sources. I would challenge both of those ideas. And our ability to digest dairy decreases with age so what worked at 20 may not at 50, reassess.

Do you eat dairy? How much and which types? Have you considered decreasing or desisting?

Rethinking Skim Milk

I went to college when “fat free” was all the rage.  Snackwells, skim milk and fro-yo were in. Avocado was out. As absurd as it sounds to recount this now, it’s even funnier to think that I was in New Orleans, land of beignets and muffaletas. Little did I know that my eating regime was as off-kilter as the city’s cuisine.  Aside from improved nutrition knowledge and time to “mature” what strikes me about this type of eating is how poorly it must’ve tasted. How many cups of greyish coffee did it take to prove this point?  A few too many.  I write this to show you how easy it is to get swept up in an eating trend or prevailing nutrition advice.

You will not find skim milk in my refrigerator today and I’m proud to say my day starts with coffee and a splash (or 2 splashes) of  delicious half and half. (currently Sky Top farms grass-fed, non-homogenized, adore it). I also didn’t switch my kids to  1%  at 2 years old as the current advice from the AAP suggests. After my brief “blue period” I went back to how I was raised. A little bit of the real thing is best.

I’ve posted before about organic milk and ultra pasteurization but it wasn’t until a couple of years ago  that I realized the potential problems with skim milk. My interest was first piqued reading Walter Willet’s Fertility Foods. We have many clients trying to conceive and the research about skim dairy and infertility floored me. Low-fat dairy contributed to infertility (when issues are based on anovulatory failure) and full-fat dairy increased fertility.  What really turned me off was the proposed reasoning. When the fat is removed from milk, the portion that’s not fat contains more androgens and other hormones that may not be conducive to fertility.  The androgen argument may explain why another Harvard study found that teenage boys drinking skim milk had a higher incidence of acne.  Again, what’s in the fat or skimmed out seemed to help.

Last week, I read an article posted by my colleague Julie Negrin entitled “Is Skim Milk Making You Fat”. The article challenges the traditional “low fat dairy for health and wellness” dogma.   They write:

It’s becoming widely accepted that fats actually curb your appetite, by triggering the release of the hormone cholecystokinin, which causes fullness. Fats also slow the release of sugar into your bloodstream, reducing the amount that can be stored as fat.

I find this so interesting as we have a country that's watching dietary fat and getting fatter.  It always seems to me that children have the best innate sense of calorie regulation. An Australian study in the American Journal of Clinical Nutrition showed that children’s calorie intake did not change when they were switched to low-fat milk. Children replaced the calories with other energy sources and did not lose weight.  Another large study tracked the habits of 19,252 Swedish women for 9 years. Women increasing their whole milk consumption the most lost 9% of their body weight, on average. Women who increased their low-fat dairy the most gained 10%.

Anecdotally, I am also concerned about skim milk and bone health. Fat in milk can help us assimilate vitamin D. I have not found a tremendous about of research on this but have seen many 30-something clients who grew up on low-fat milk now with osteopenia and fractures. I’d be curious to see if the very thing we think is helping us may not be.  This whole debate reminds me of the whole butter versus margarine debate. On that subject, the great Joan Gussow said “I trust cows more than chemists.” The more I read about the processing involved in making skim milk palatable, I think this applies here too.  If you eat dairy, I would suggest a little bit of the real thing.

Do you purchase milk? What type do you buy? Are you skeptical of skim milk?
