Inside: Good news! Dark hot chocolate can help improve the memory of older adults! The best antioxidant levels are found in unprocessed cocoa powder but dark chocolate also ranks high in its memory boosting properties.

Memory Loss and Ageing
[bctt tweet=”Who’d have thought that your evening cup of hot chocolate could boost some memory skills! “] As we get older, remembering names of new friends, where you put those elusive car keys and my person favourite – where I parked my car in the mall parking lot (isn’t that why I bring my kids with me???) become problematic at times. According to the Columbia University Medical Center (CUMC), age-related memory decline begins in early adulthood but doesn’t become really noticeable or problematic until the ripe old age of 50 or 60 – somewhere I am about now 😥 And I must say, I do notice it. I now have to really focus on where I leave my car in the mall parking lot. If I don’t, I’m trying desperately to maintain dignity while I try not to appear to be looking for my lost car. So, why might hot chocolate be the panacea for your failing memory? Flavanols are the key but first lets look at the reason behind those troublesome lapses of memory.
Dentate gyrus and Pattern Separation
Why do we tend to suffer this age-related memory decline? The dentate gyrus is part of the hippocampus complex of the brain. It is a pattern separator. Two similar memories which could be easily confused such as where you parked the car at the mall today compared with where you parked the car at the mall two days ago can be distinguished by the processes of the dentate gyrus. As we age, this structure tends to suffer from similar breakdowns felt in other parts of the body and our keys get misplaced so we have to take our children shopping to relocate our car in a parking lot 😉 .
Cocoa Flavanols Boost Memory
But as with many structures and bodily functions that degrade as we age there is hope in some of the simpler pleasures of life. The cocoa bean, which is the secret to delicious hot chocolate, is a high source of flavanols. The CUMC study included 37 healthy individuals in the 50 to 69 age-range bracket. They were randomly given either a diet high in flavanol (900 mg per day) or a low-flavanol diet (10 mg per day) for three months. They were subjected to brain imaging which measured blood volume in the dentate gyrus, and memory tests both before and after the study. The memory tests involved 20 pattern-recognition tests designed to measure the functioning of the dentate gyrus. Those taking the high flavanol diet showed significant improvement in the functioning of the dentate gyrus. Lost keys should now be a thing of the past for these folks!

Antioxidants help to neutralize the effects of free radicals in the cells which tend to damage chemical pathways. Flavanols are found in many plants including tea and red wine but are particularly abundant in the cocoa bean. Flavanols not only improve memory but seem to reduce blood clots and cut the amount of bad cholesterol in the bloodstream.[/cow_johnson] It’s not just any hot chocolate that has an abundance of these flavanols. Processing of the cocoa beans can remove most of this important antioxidant. The best antioxidant levels are found from highest to lowest levels in:
- unprocessed cocoa powder
- unsweetened baking chocolate
- dark chocolate
- semi-sweet chocolate
Raw cocoa powder can be purchased on line or at most health food stores. Add hot water, honey or agave syrup for a delicious cup of hot chocolate. Add the powder to your daily smoothie for an added health boost. I like adding cocoa or dark chocolate flakes to my morning or afternoon latte. Adding a cinnamon stick or powder is a delicious addition but also another healthful option (a post for another time). Mmmmmm
Hot Chocolate is Good
Flavanols appear to be concentrated in the solid part of the bean which is the origin of cocoa powder. Cocoa butter, also a part of the bean comprises 50 to 60% of the weight of the bean. The butter itself is not high in flavanols although it does give chocolate its characteristic gooeyness and most of its calories. Now, don’t go pigging out on chocolate to boost your memory. There is a “Goldilocks Zone” about how much of a good thing will actually give improvement. [cow_johnson general_float=”right” general_clear=”none” general_width=”300″ general_bgcolor=”#ff964a” general_font=”Lucida Sans”]“It has been shown as proof positive that carefully prepared chocolate is as healthful a food as it is pleasant; that it is nourishing and easily digested … that it is above all helpful to people who must do a great deal of mental work.” —Anthelme Brillat-Savarin (1755-1826),French Magistrate and gastronome[/cow_johnson] Considering 1 ounce of dark chocolate has 170 calories, 12 grams of fat and 7 grams of sugar, too much will really add to the waistline. One or two ounces a day are good for some health benefits of improved cardiovascular health as well as improved memory. After that, well you know, too much of a good thing becomes a bad thing! Of course, you can always rely on supplements. Calories are avoided and your memory might gain an extra boost— but what fun is that!!!

Thank you my dear. My husband and I have 1.5 ounces of 70%+ dark chocolate every day. Can’t say for certain it’s helping me remember things — but will take your word for it.
Think I’m going to add cocoa powder to my latte. Give a boost to my guilty pleasure!
Teresa, this is the thing, I don’t want my waistline to expand further and I am starting to have memory lapses. Yikes. I enjoyed reading this article. I just had a couple of Girl Guide Dark Chocolate cookies with mint before dinner. Now I am forgetting to eat dinner. Are you a consumer of Flavanol?
I do take phytosterols which are very similar antioxidants. They are plant based and we’re recommended by my doctor for blood cholesterol which is on the high end of normal. My next blood work showed an improvement so I’m a believer. Having a cup of cocoa right now:)
phytosterols what? Is that available at Health Food Store? I’m having herbal tea.
Yeah they are. They’re plant sterols also antioxidants. They seem to be having a positive effect on my blood chemistry.
Thanks, I’ll drop by at the store tomorrow. Enjoy your choco.
