Let them eat chocolate cake for breakfast!

IMG_4341

I saw the headline: Chocolate cake for breakfast? Research says it’s good for both your brain and your waistline and thought “this should be interesting”.

The author suggests that we should eat chocolate cake for breakfast because one study found that higher chocolate consumption was associated with improved cognitive function. While another study suggested that those who ate larger breakfasts (including a dessert) lost more weight and ate less later in the day than those who started their day with a less substantial meal. A bit of a leap, if you ask me to then conclude that we should be eating chocolate cake as part of a weight management cognitive enhancement regimen.

Looking at the study that ostensibly concluded that chocolate improved cognition, it immediately jumps out at me that the study drew from data from food frequency questionnaires. As you know, these are notoriously inaccurate. I also think that it’s important to note that the questionnaire in question didn’t differentiate between dark, milk, and white chocolate. White chocolate being up for debate as to whether or not it’s truly chocolate, and the form of the chocolate not being recorded (chocolate bar, ice cream, cake, cookie…) it would be difficult to conclude that there was any one attribute of these forms of chocolate that could improve cognition. As the authors point out, there is no way to infer a causal relationship. Just because people who ate chocolate at least once a week fared better on cognitive tests than those who ate it less than once a week doesn’t mean that there’s not some other reason that they fared better on these tests. While the results were statistically significant, I wonder how meaningful they are in actuality.

While I can attest to the benefits of “front loading” your day for many trying to lose weight or maintain weight loss, I wondered about the study the article referenced. Fortunately, someone else had already thrown shade on it (back in 2010!) so I don’t feel the need to duplicate their comments. For anyone who can’t be bothered to click the link, suffice to say the study author has come out with a diet book and the study upon which she based this plan is flawed.

Okay, what’s the takeaway? I’ve got nothing against chocolate. I’ve got nothing against chocolate cake. In fact, writing this post prompted me to fetch a slice of leftover chocolate cake to munch on while I typed. That being said, I wouldn’t include it as part of a nutritious breakfast. If you were eating chocolate cake for breakfast on the regular you’d be hard-pressed to get all of the nutrients you need without getting more calories than you need. If you want to add chocolate to your breakfast in a healthier way you could add some cocoa powder to your smoothie or some raw cacao nibs to your oatmeal. Save the cake for special occasions (and blogging).

Supplements: Should I take truBrain drinks?

I guess promoted tweets do come in handy every now and again. Blog fodder. This tweet appeared in my feed last week:

Naturally, my response was: that sounds like complete and utter bullshit.

I went to their website to look for the science to back-up their claims; i.e. an increase in productivity. Naturally, the truBrain research team conducted the study. Surely no bias there. The study itself? Seven. Yep, seven, participants were examined for changes in EEG results following one week of truBrain consumption. The EEG was used to measure brain activity. There was no control group and no blinding (read: high likelihood of bias). Even with the deck so well stacked in their favour, the “researchers” found no significant results at a group level. This pilot study is the only research cited on their website.

Okay, so there’s no real science to support the claim that truBrain can increase productivity. Perhaps a look at the ingredients can provide more illumination:

375 mg of CDP-Choline – The lovely folks at examine.com indicate that there is some minor evidence to support the use of CDP-Choline to support memory and attention, and decreased cognitive decline in older adults. If there is a benefit conferred by CDP-Choline, this might be an effective dose.

200 mg of DHA – This is an omega-3 fatty acid. There may be benefits seen at this dose, although there is no scientific consensus. Also, benefits are most likely seen in individuals who do not regularly consume fatty fish.

375 mg of L-carnitine – This is quite a low dose. While there is some limited research to support the use of L-carnitine to increase cognition in the elderly, there is no research to support its use in the young.

300 mg of L-theanine – This is an amino acid that may promote relaxation. There is no research supporting its use to improve cognition.

375 mg of L-tyrosine – Another amino acid. As a supplement, it may reduce stress and memory in the presence of an acute stressor.

120 mg of magnesium- Many of us don’t consume enough magnesium in our diets so it’s hard for me to knock the inclusion of this mineral in their beverage. However, this is a rather low dose. Some forms of magnesium can cause gastrointestinal distress and diarrhea. It’s also important to note that magnesium supplementation is unlikely to have any effect on cognitive performance.

800 mg of oxiracetam – This is a mild stimulant that may improve memory but there aren’t currently human studies to support this.

In addition to the “medicinal” ingredients, truBrain drinks also contain the following “natural” sweeteners: pomegranate, stevia, blue agave, cranberry, sugar cane, and monk fruit. Six sweeteners. Sweet enough for ya? Not mentioned in any of the ingredient lists is caffeine. The website shows an option for purchasing “non-caffeine drinks” but at the moment they have not yet developed any.

At the low end of the scale you can purchase 15 drinks for a one time fee of $60 or $50 per month. That’s $4 per packet. Unfortunately, the website doesn’t clearly state the size of each drink packet nor the full ingredient list or nutrition information. Without complete information, I can’t completely rip these truBrain supplements to shreds.

Apparently these supplements were developed by neuroscientists. While this might seem to lend an air of believability to their claims, it truly only shows that no profession is exempt from quackery and the desire to turn a profit.
