Folic acid and DHA: Working to reverse cognitive decline

brain

The top fear about aging is declining mental capacity. My guess is many of you have fears about cognitive decline. I do too, especially when observing the devastating effects of dementia and similar diseases on family members.

Be positive: Cognitive decline is on the increase in the United States and worldwide, but the increase is primarily driven by the reality that the population is getting older and people are living longer. There is a lot of evidence that preventative strategies are actually reducing the risk of cognitive disease.

Case in point: I want to highlight a new study about folic acid and DHA.

Folic acid is a B vitamin that helps your body grow new, healthy cells. DHA (Docosahexaenoic Acid) has a similar function in the body but is especially important for brain tissue.

A recent study suggests that folic acid and DHA together not only stop cognitive decline but slightly reverse it.

In the study, one group took just folic acid, one group took just DHA, one group took both, and a control group took neither. While the groups taking only folic acid and only DHA saw some improvement, the group taking both DHA and folic acid saw the most improvement by far.

Here is a warning: After the trial, the subjects were retested, and the positive impact of folic acid and DHA diminished extremely fast after the participants stopped their regimen. Keep the nutrition flowing.

The primary diet sources of DHA are seafood, eggs, and some plant sources such as flaxseed. You can get folic acid primarily from green vegetables. And, of course, you can get both nutrients from high-quality supplements.

5-HTP and your appetite

hands with capsules

5-HTP is a fairly popular supplement here at Caring Sunshine. Let’s talk about why:

5-HTP is, first and foremost, a naturally occurring amino acid. For today’s discussion, it is important because it assists in the body’s production of serotonin, which regulates mood, sleep, and other mental issues.

By the way, the regulation of serotonin is the main premise behind most of the depression medications on the market. In fact, like many supplements, 5-HTP is also manufactured and used as a drug.

Here is something you should know: There is very strong clinical evidence that 5-HTP improves mood. And, when the mood improves, eating behavior changes, which leads to weight loss.

Here are two studies:
https://pubmed.ncbi.nlm.nih.gov/1384305/
https://link.springer.com/article/10.1007/BF01578751

In these two studies, subjects who used 5-HTP decreased caloric intake. In fact, the results were so dramatic that, in one of the studies, a diet plan was advised for people using 5-HTP to avoid the risk of eating too little.

In the other study, people taking 5-HTP ate less carbs but reported feeling fuller for longer.

Even if you have no interest in 5-HTP, here is a key weight management principle: Your mood matters. There is a connection between mental stress and increased eating; people who are under stress just tend to eat more.

For that reason, a good weight management program should put some focus on mental state, emotions, and sleep.

Disclaimer: 5- HTP should not be taken without asking your doctor if you are on any type of mental health medication (especially an antidepressant).

Physical activity’s role in immune health

feet and stairs

Our immune systems are under attack this time of year, but there are ways to reduce your chances of getting sick.

One of the things you can do? Move more.

Obviously, physical activity has many benefits including a positive effect on our metabolism, heart health, brain function, and even mood.

But, while few know this, modern science tells us that physical activity also supports immune health. PubMed has an amazing collection of studies on this topic: https://pmc.ncbi.nlm.nih.gov/articles/PMC6523821/#bib0021

One particular study found here suggests that regular 30-to-45-minute moderate-to-vigorous exercise is beneficial to immune function.

In the study, a group of healthy and active elderly women were divided into two groups: walkers and non-walkers. The walkers were told to walk three times a week with an elevated heart rate.

After 10 weeks, the participants were tested for cellular immune function, and the walking group had far better immune function than the non-walkers.

Make sure and keep moving through this sick season.

Why you get sore and what to do about it

man stretching

Being sore after an active day or workout is a common experience for most of us. If you can believe it, medical professionals and researchers are still trying to figure out what actually causes muscle soreness. One popular theory is that microtears are created when you strain your muscles. Those microtears cause the pain that we associate with soreness.

Delayed onset muscle soreness (DOMS) is the soreness you develop between 12 and 24 hours after a new activity, but not during the exercise itself. While painful, DOMS is not dangerous.

DOMS usually goes away on its own, and there aren’t a lot of safe medical treatments for DOMS symptoms. In particular, the anti-inflammatory drugs a doctor may prescribe should not be used for long.

Fortunately, other remedies are available, and there is good research behind them!

Magnesium has been proven to help with symptoms and recovery after exercise, though it has only been studied on a short-term basis. Here are two studies demonstrating a significant benefit when magnesium was added to the subject’s diet: Study A and Study B.

In this study, saffron was found to be highly effective in treating DOMS symptoms. Those who took a 300 mg supplement of saffron were able to continue to exercise and recover faster than those who received the placebo. More studies are needed, but there is more about saffron later in this email.

What is the best (and cheapest) way to recover from DOMS symptoms? Move more (low intensity is fine). A long walk or swim may help if you are struggling with soreness.

Important note: Please pay attention if your DOMS symptoms last more than a week or are painful rather than sore, and reach out to a healthcare professional if necessary.

Play Tetris in 2025?

I ran across a study this week suggesting a counterintuitive way to help your brain in the areas of concentration, work engagement, burnout, work stress, and sleep: playing Tetris.

The study took place in Sweden during the COVID-19 pandemic and studied healthcare workers who had been traumatized by their work (PTSD). Participants who played Tetris (and similar games) on their phones for 20 minutes reported a median 80% decrease in intrusive thoughts (compared to the control group), better work engagement, less burnout, less stress at work, and better sleep than the control group.

I am not suggesting that there is anything special about Tetris. The point is that if you give your brain a bit of a break during the workday, it will improve your quality of life. A modest change in lifestyle can make a big difference.

Now, I want to make a point about 2025. If you are on social media, you may have noticed that extreme health challenges (ice baths, marathons, etc.) are all the rage.

Feel free to think smaller, but I want you to make a few modest health resolutions for 2025. Get consistent with sleep patterns, engage in modest exercise (such as walking), and eat food that is good for your mental health.

And, don’t feel guilty about playing some Tetris. In other words, step away from the stress of life for short periods of time throughout the day.

Why coffee isn’t a great diet hack

cup of coffee

Resolving to lose weight is a very common resolution during this time of year, and for sure, exercising more and leading a healthier lifestyle are always good ideas.

Sometimes, however, vague resolutions about weight loss can lead to unhealthy choices, and taking on an extreme diet to cut calories often falls into that category.

Another potentially problematic tool for losing weight? Coffee.

Coffee is not all bad. It is packed with antioxidants, and drinking black coffee may actually help you process glucose. Johns Hopkins actually produced a fun article outlining some benefits of drinking a moderate amount of coffee.

The caffeine in coffee is also a stimulant, which may increase the metabolism, which in turn burns more calories throughout the day. That is why many popular weight supplements contain caffeine. I don’t like the way excessive stimulants make me feel, and generally would never consider them in a weight loss regimen, but many find value in them.

On the other hand, a common misconception is that coffee curbs hunger. That is debatable. In this study, overweight and obese women were given either water or black coffee with breakfast. Over the course of the day, the women recorded how they were feeling. Here are some interesting findings that don’t necessarily help a pro-coffee argument:

1) Appetite levels were the same in both groups.

2) The coffee drinkers desired sweet foods more than the water drinkers.

3) The coffee drinkers had higher triglyceride levels.

More testing needs to be done to show the actual results of using coffee to curb hunger, but what we know is that coffee consumption is not a fool-proof diet.

If you do choose to consume coffee (as I do), moderation is key. Drinking excessive amounts of coffee to curb hunger is a dangerous and unhealthy practice. All benefits that coffee offer fly out the window if you choose to go too far.

According to Johns Hopkins, a healthy amount of coffee is 3-5 cups (8 oz) for men and women who are not breastfeeding or pregnant.

It is best to avoid adding sweeteners and/or cream. If you can’t drink black coffee, try using pure maple syrup in small amounts.

Disordered eating and vegetarianism

brussel in teal background

Recently, I found a group of studies that focused on the link between disordered eating in young people and vegetarian/vegan diets. Because we are seeing an increase in disordered eating, this is a topic worthy of discussion.

To start, let’s define terms:

Disordered eating, in this study, is any type of eating that restricts calories to under the bare minimum of what is considered healthy. It is almost always done without the help of a dietitian or doctor. Anorexia is an example of disordered eating.

Vegetarianism is the practice of not eating meat. For the purposes of this discussion, when I say vegetarianism, I am including vegetarianism and all its various derivatives (including veganism which forbids animal byproducts as well).

Here is something shocking: In 20 different study groups with over a total of 14,300 subjects, researchers found a significant link between disordered eating and vegetarianism.

While a strong correlation was found, researchers stopped short of saying that vegetarianism is in itself disordered eating. This is clearly not true; many people stay healthy on a vegetarian diet.

But, at a minimum, there is evidence that a lot of young people in particular who are choosing vegetarianism need more guidance because they are simply not eating enough. Remember that vegetarian foods in general tend to be low-calorie, and a large number of foods that are high in calories are not vegetarian-friendly.

Now, here is another more troubling hypothesis: some young people who struggle with disordered eating may be using vegetarianism as an excuse to explain why they may be refusing foods.

What do we take away from this? Here are some thoughts:

  • If you are a vegetarian, make sure you are consuming enough high-calorie foods to hit your minimum caloric intake (1600-2000 calories/day). Remember that calories are not bad; in fact, they are a  measurement of energy.
  • If you have children or other loved ones who are vegetarian, check up on them in a loving way to make sure they are getting the calories they need.
  • If you have children who are vegetarian, be on alert for signs that they may be using vegetarianism to cover up a deeper problem like anorexia.

What you should not take away from this study is that vegetarianism is bad in itself or constitutes disordered eating. Remember that correlation does not equal causation.

If you wonder how many calories you should be consuming a day, try this handy calculator.

Got the guts? Why gut health is important and how to make your gut healthier

BOWL of fruit

Many are writing about gut health these days, and I am going to jump on that train too. Let’s talk about what gut health really is and how you can make your gut healthier.

Remember that gut health is complicated, and I am not prescribing blanket solutions for all gut problems. Listen to your body, stay balanced, and take this advice (along with all other advice) as a suggestion.

Gut health refers to the state of your digestive system. This system is responsible for two things:

* Absorbing what your body needs
* Removing what your body doesn’t

While these two jobs seem simple, there is a lot that can go wrong, especially in the arena of bacteria. Your whole digestive tract contains a collection of bacteria, but that isn’t a bad thing. In fact, this bacteria is critically important, and your collection of bacteria is called your microbiome.

The key thing to know about your microbiome is that it needs to be balanced. There are many different kinds of bacteria (some good and some bad). You need lots of different strains of bacteria in the body.

Many things can contribute to what is happening in your microbiome, but there are two ways in particular that people try to control the balance: antibiotics (which are supposed to target/eliminate bad bacteria) and probiotics (which are supposed to replenish good bacteria).

Antibiotics do their job and have saved millions of lives, but often at the expense of eliminating good bacteria as well as bad bacteria, which creates an imbalance in the gut. The typical American diet does not help promote healthy bacteria either.

For these two reasons, probiotics are extremely popular. Probiotic capsules contain billions of good bacteria CFUs (colony forming units).

We sell probiotics of course, and the choices can be overwhelming. Check out this video from Greg where he discusses what you should be looking for when choosing a probiotic.

While probiotics can be very useful, bacteria is not the only gut health factor you should be concerned with. According to John Hopkins, when trying to improve your gut health, getting enough sleep, managing stress, and moving more are just as important as your diet.

That being said, your diet should have a healthy amount of fiber and good bacteria. Foods like Greek yogurt and kefir are chock full of natural probiotics. In general, fermented foods are rich sources of healthy bacteria.

But, if fermented foods aren’t your favorite, as this study shows, probiotics are a proven way to relieve gut issues and support a healthy change in microbiomes.

Vitamin D and exercise vs depression

Hand on window

You may hear about seasonal depression this time of year, and some of you may even experience it. While our society is improving access to mental health help, we still have a long way to go, so let’s talk about this condition in particular.

Studies show that lack of sunlight may cause seasonal depression, but is that really the cause? That is a loaded question. This week, I am including two articles that may help some of you with the upcoming winter season.

I’ll start by explaining that there is no confirmed source of seasonal depression, and the condition isn’t fully understood. That said, there is a positive correlation between taking vitamin D and reduced depression symptoms. Many studies show that those who maintain healthy levels of vitamin D report fewer symptoms of depression.

If you are feeling depressed, a good start is to check your vitamin D levels. I do want to be clear that vitamin D does not cure depression, but it does help. That is especially true with conditions like seasonal depression and postpartum depression, which happen on a sporadic rather than permanent basis.

Exercise is also a valuable tool that can lessen seasonal depression. The CDC has released guidelines on different levels of exercise, and several studies have been released demonstrating exercise’s beneficial effect on depression.

In a study done on nearly 1,800 people, people who did a combination of aerobic and anaerobic exercise had less risk of developing depression. People who did very intense aerobic and anaerobic exercise had even less risk.

To summarize, exercise and vitamin D are not magic bullets, but they are valuable tools to help you fight seasonal depression. Make sure to get in plenty of outside walks this season.

Important note: Depression can be a very serious health condition with huge risks. If you have severe depression symptoms, please get professional help. Your life could depend on it.

The next article gives you an interesting way that you can make sure that one of your kitchen ingredients has the most vitamin D possible.

Green vegetables and blood pressure (and a tasty recipe!)

asparagus bunch

Vegetables have long been used in various diets to achieve a range of health benefits. There is little debate when it comes to vegetables and their relationship to a healthy life, but are some vegetables better built for helping with blood pressure?

A recent study conducted by fourteen top biomedical professors suggests that cruciferous vegetables have a more significant effect on lowering blood pressure than other squash and root vegetables in middle-aged adults over a short period.

Here is the published summary if you are interested: https://pubmed.ncbi.nlm.nih.gov/39218859/

Cruciferous vegetables (named for the shape of their leaves which resemble a cross) include broccoli, kale, cabbage, Bok choi, cauliflower, and similar mostly-green options. You can see a complete list here.

We know that these vegetables have glucosinolates, which are known to help with blood pressure problems in animals. Additional studies are taking place to prove their effectiveness for humans. Glucosinolates do have proven benefits in humans including protecting cells from DNA damage. They inactivate carcinogens and have antibacterial and antiviral effects. These super veggies are also a great source for folate, fiber, and vitamins C, E, and K!

If you’d like to read about more benefits of these vegetables, here is an article:

Cruciferous Vegetables: Health Benefits and Recipes

While this study produced interesting results, I wouldn’t throw out all my carrots and replace them with kale just yet. More studies need to take place before we know how much we have to eat of these cruciferous vegetables to make a long-term change in our blood pressure. It is also good to remember that the study was done on selected individuals who were in a specific age range and with preexisting issues. This study represents only an interesting start to fine-tuning our diets for blood pressure.

In honor of the study, we have included a recipe for the cruciferous asparagus vegetable below. We think it would be a wonderful addition to your holiday meal this week.

The Best Asparagus (Ever)

Ingredients
2 bunches fresh asparagus (the thinner the better!!)

3 tbsp lemon-infused vinegar
3 tbsp avocado oil

Instructions
Chop the fresh asparagus in half.
Slice your onion and mince the fresh garlic.
Add the avocado oil to pan and heat on medium. Add onions and garlic. Saute for 2-3 minutes and add asparagus.
Juice the lemon and add it to the pan along with the lemon vinegar, spices. Cover.
Cook for 20 minutes stirring occasionally. Add additional oil or lemon vinegar as needed.
Taste asparagus once soft and adjust spices as needed. (They vary depending on the size of the asparagus.)
