Fermented & Healthy

We’ve talked in a previous article about the health benefits of probiotics and prebiotics. We know that staying healthy requires maintaining a healthy microbiome. We also know that you can get legitimate supplements to supply both but the best way is really through your balanced diet. One of the best sources of pre- and probiotics is fermented food. Anything like yogurt, kimchi, sauerkraut, miso, or even beverages like kombucha or kefir will provide some level of probiotics! These are things that are regularly consumed around the world and now we are seeing the value beyond their unique flavors and umami filled tastes. In addition, it is also important to consume prebiotic foods! Some of these include garlic, honey, onions, chicory and resistant oligosaccharides. 

The benefits of fermented foods therefore track pretty closely with the benefit of a healthy biome with both probiotic and prebiotic support. There is a boost to cardiovascular health and the mitigation of high blood pressure. Diabetes, obesity and really anything inflammation based chronic illness benefit from the inclusion of fermented foods in one’s diet. Additionally, mental health and bone health also improve as the microbiome is supported. 

Check out this short video going over some easy to incorporate fermented foods!

Once You find a fermented food that you enjoy, getting the necessary pro-and prebiotics in you diet will be easy and natural and will be in a more absorbable form that simply taking a capsule.

Wheatgrass 101

Occasionally a food fad will sweep through in a summer and is gone before most of us truly understand what all the hype was about. Sometimes, though, when the “fad” seems to be a little more substantive, it graduates to a higher status in our minds, shared with other accepted parts of alternative or holistic medicine. Frequently, this tends to be the case when the remedy or practice is actually well-known and even commonplace in another part of the world but has only recently made its way into American culture. Such a path seems to be the case with the wheatgrass phenomenon. A few summers ago, wheatgrass seemed to explode into the smoothie and juicing market. Almost overnight, juice bars and health food stores nudged the charcoal over to make room for this bright green contender in the limelight. It’s been a few years and wheatgrass doesn’t seem to be going anywhere. So, what’s all the fuss about? 

Wheatgrass is the young grass of the common wheat plant Triticum aestivum. It is very high in chlorophyll, flavonoids, and an assortment of vitamins and minerals. It’s also known for its iron, calcium and amino acid content. It can be frozen but it’s usually juiced and taken in smoothies or in “shots” of a few ounces at a time. It’s reputation for being anti-cancer and generally healing seems to come from its high chlorophyll content. Chlorophyll is thought to have antibiotic and anti-inflammatory properties. Fans suggest uses from drinking it to cleanse the liver to rinsing with it to eliminate a toothache. 

Some of the claims of wheatgrass users may be a bit of a stretch but what we do know is that drinking wheatgrass does seem to induce synergistic benefits to chemotherapy and might assist with the mitigation of chemo side effects. There is also evidence that the anti inflammatory properties may help with arthritis, diabetes, colitis and other inflammatory diseases. Also, while a shot of this might contain a lot of the nutrients you need from a diverse helping of veggies, it will not replace the phytochemicals and complete nutrient profiles you would get by eating a variety of veggies. There are also a few drawbacks. If you have a gluten allergy or are pregnant, it is recommended that you avoid wheatgrass. The first group for obvious reasons and the second group because this supplemental food is unregulated and you could be exposed to contaminants and unexpected toxins. 

At the end of the day, it looks like wheatgrass may be healthy and even helpful though not a replacement for a balanced diet. Some of the claims are not rooted in the facts but other benefits are pretty straightforward. If you decide to try wheatgrass as a way to improve an inflammatory disease,  remember that it is supplemental and not meant to be in place of regular care. As also, we do not intend the information here to be used in diagnosis for prescription purposes but only to inform as you make your own dietary decisions. Buy local (sometimes you can even grow this at home yourself) and if we can help you in your product research, don’t hesitate to reach out!

Biosolids: What You Need To Know

You may be familiar with the idea of wastewater, or water run off from the sewers and other human activities being treated for continued use. This includes storm runoff, industrial sewage, and water containing human waste. Urban areas are huge producers of this dirty water and contaminants such as bacteria, viruses and more thrive in it. Thus, treatment plants like the Point Loma Wastewater Treatment Plant, treat wastewater everyday, removing the water and straining it of solid matter (about 80% of it anyway) before distributing it back into the ocean. The solid particulate matter is then pressed into a concentrated mass that is distributed and used in a variety of ways. This concentrated mass is called biosolid.

The approximately 7 million metric tons of biosolids are treated depending on what class they are categorized into. Class A biosolids are treated to reduce the number of pathogens but are used in parks, home lawns, golf courses, etc. Class B undergo a more stringent pathogen reduction process and are thought to have a lower level of pathogens than animal manure. Class B is used for fertilizers in agriculture and forestry.

Currently, there is a question about the chemicals that remain in biosolids, either before treatment or because of treatment. Things like PFAS which were not previously regulated may pose a significant issue as the currently processes used to make biosolids are not always tailored to reduce or remove PFAS.

Check out this video explanation or the filtration process:

Britannica Video

One thing to consider is the impact PFAS will have on this process. We’ve already seen some issues as we learn more about the issue of PFAS in our water supply. Since PFAS do not breakdown, we may need to approach the release of processed waste water back into our natural sources of water. Even the use of biosolids in general may have an unknown impact on our supplies of pure groundwater and thus eventual drinking water. It’s more important than ever that we stay well informed of what is being done to protect our ground water and pure water sources as well as what we are moving towards in the regulation of PFAS.

PFAS and Waste: What to do with it?

Cut Carbs Some Slack!

You’re staring down at the leftover sweet potato casserole from Turkeyday and thinking about how many carbs that basically-a-pie entree probably carries. It’s so good but it’s so heavy! In fact, looking at the bread, stuffing and mac-and-cheese, you begin to wonder if you shouldn’t just skip carbs entirely for a while. Low carb diets are better anyway, right? Let’s take a look.  

Carbs are one of the most readily available forms of energy the body has access to. When you go to exert yourself in any way, carbs supply the fuel that lets you push. This is especially true in regards to physical workouts and exertion. Carbs are a big part of what are bodies’ run on. So then, are carbs good? Hmmmm, it’s a little more complex than that, though in this case complexity is a good thing 

Carbs can be classified in a couple different ways. The most common is probably by type. There are sugars, starches and fiber. Sugars include those naturally occurring in fruits and veggies or dairy products, as well as processed sugars like what you use to bake or what’s found in almost anything sweetened. Even things like high-fructose corn syrup and agave nectar fall into this category. Sucrose, fructose and even lactose are all, technically, carbs. 

Starches include grains like rice, beans, potatoes and even corn. Starch is a densely packed pod of energy that a plant forms to store what it collects from the sun. It is usually wrapped in an outer shell of some kind which in the case of grain consists of a bran and germ. This fibrous outer layer is filled with vitamins and minerals and is the reason whole grain foods are generally considered to be more balanced and nutritious than refined ones. 

Fiber, as we’ve discussed in a previous blog, is the indigestible part of foods like beans and legumes, fruit and veggies, whole grain foods and more, that mostly passes right through the body but has a big impact on digestion and gastrointestinal regulation. It allows you to absorb more nutrients from your food and to regularly pass what the body doesn’t need. Fiber is hugely important and also falls under carbohydrates. 

You can probably tell right away that the idea of totally cutting out carbs might not make as much sense as you may have been told. A lot of the healthiest and important foods we need are technically carbs. Fiber, for example, is crucial to digestion and adults in the US get only a small portion of what is recommended (which according to the American Diabetes Association is about 25 to 30 grams a day). Carbs aren’t always bread and potatoes. Sometimes they are split peas and corn or bananas and almonds. 

The amount of carbohydrates that each person needs is much more dependent on the individual than any blanket statement could cover. The pile of gooey marshmallows topping that sweet potato casserole might be something to consider when cleaning up Thanksgiving leftovers but keep in mind that not all carbs are created equally!

Stay Well While You Stay Full!

This holiday season it is more important than even that we take care of our physical health. We are all excited to experience a more traditional holiday season but we should still approach this second Covid season’s greetings with caution! If you are traveling home to see your parents or away from home to see the kids, make sure you are still practicing excellent hygiene and getting enough sleep and exercise to support a solid, natural defense system against viral intruders. As this holiday often centers around shared meals, you might want to keep these nutrients in mind as they too will help your immune system stay battle ready!

First, as we’ve mentioned before, a big part of our immune system relies on the microbiome, a collection of trillions of microorganisms that live inside our gastrointestinal track and help with bodily functions from breaking down food to destroying harmful bacteria. Fermented foods like kefir or sauerkraut support this system with their probiotic content. Just as important are foods containing prebiotic material such as garlic, bananas and beans! Stock up on these microbiome happy nutrients to give your system that extra push.

It’s a given that vitamins and minerals support our immune system and the lack of certain vitamins and minerals can stunt our bodies ability to fight off infection. Sometimes, it is difficult to get enough of certain minerals and vitamins from one’s diet consistently but a well rounded and balanced diet increases that chance. A wide variety of fruits and vegetables can also help and there are some vitamins and minerals that you can focus on specifically to make sure your body has the ammo it needs to be ready for that one particularly snotty-nosed nephew you just “have to hold.” According to an article from Harvard’s School of Public Health those nutrients are zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, D, and E. 

Vitamins and minerals are everything though so do your best to limit your overall stress as much as is possible and as much as these two hints might seem counter intuitive, limit your alcohol consumption. Time with your family is amazing but make sure you prioritize time to reset and recharge so everything stays happy, healthy and whole! Happy holidays!!

The Death of Coffee: A Global Warming Caution Sign

“Coffee is popular,” might just take the grand prize for the most understated truth of the era. Coffee isn’t just popular, it’s a global industry worth over 100 billion dollars and spanning every single continent. So popular that the myth of it being the second most traded commodity after oil was believable if not quite accurate. Coffee is definitely in the top 100 globally though and many countries owe more than 5 or even 10 percent of their economic foundation to the coffee trade. 

Roughly 2.25 billion cups of coffee are consumed around the world each day and in many ways, we’ve created a coffee dependent work cycle worldwide. Can you imagine the impact that a shortage of coffee might cause? From the agricultural pipeline to the consumer pool made up of about 15% of the world’s population, we’d be in for a miserable awakening.  It’s virtually unthinkable. Even so, a shortage might be exactly what we are heading straight for.

Coffee comes in a number of varieties and is grown all over the world with the bulk of it coming from places like Brazil and Ethiopia. These places have the combination of climate, soil type and precipitation needed to support thriving coffee variations like the very popular Arabica plant. However, in recent years, the necessary balance has been interrupted as global warning tips the scales resulting in lasting problems like coffee rust. Coffee rust is a fungus that shows up as yellow-red spots on the plant that eventually turn black and kill off the leaves and eventually the whole plant. It is horribly efficient and can wipe out entire farms of coffee plants within a few years. 

Arabica is particularly vulnerable to the fungus but plants moved to higher elevations or that are using agroforestry practices to increase the shade used to grow the plants, have seen some resistance. It is thought that global warming will continue to increase the risk to these areas of higher elevation as time goes on but these are a few ways that farmers are pushing back against the global warming threat. 

Another approach is the development of new or wild variations of coffee that are more resistant to the fungus. Right now several have been developed but are still considered lesser in quality to the more popular Arabica. They are also still susceptible to another big global warming issue: the threat of pests. The coffee berry borer is just one of the many pests that target coffee plants and though the plants can be treated, as we’ve seen in previous articles, pesticides have their own set of risks and challenges. The borer in particular seems to thrive in the rising temperatures around the world and is one more unforeseen consequence of the earth rising temperatures.

No matter what you personally believe about global warming, the challenges coffee growers are facing due to the increasing temperature averages in their regions aren’t going away. If you love your morning cup of liquid energy, perhaps it’s time to take a few personal steps to preserve it before it’s too late. 

Winner, Winner, Chicken Dinner?

You may be aware of the Salmonella Epidemic here in the U.S. that started in 2018. What you may not realize is that it is ongoing and the most recent chapter in the development of this widespread, food industry disaster was documented just last month. 

Salmonella is a type of bacteria that includes over 2,600 serotypes and normally causes severe food poisoning that typically lasts about a week. The symptoms include diarrhea, fever and stomach cramps though some strains can also cause infection in the bladder and urinary tract, the blood stream, joints and the nervous system(spinal fluid and brain). Severe disease can develop causing up to and including death. Each year, about 1.35 million people get sick from salmonella and roughly 26,500 people are hospitalized. While the number of deaths are relatively low, around 400 per year, the number of people left with debilitating conditions like severe arthritis and IBS is much higher.

The current outbreak is tied to chicken and the CDC have claimed that this particular outbreak is over. The facts unfortunately seem to show that cases of infection are still ongoing and may even be growing. This strain of salmonella has also been very resistant to the usual types of antibiotics salmonella is normally treated with and is known as Infantis Pattern 1080. A detailed report of the development of this outbreak was documented by ProPublica and will be linked to this article below. 

In this country, our main regulatory body for Food Safety, the USDA, has the ability to monitor and check for salmonella in a population of chickens and to even note if the level of the bacteria is above their health regulation but, they don’t have the power to do much more beyond engaging with shareholders and encouraging a reduction of violations for the public good. Beyond that they can take legal action against a company and perhaps fine the company but their enforcement power is pretty limited when it comes to outbreaks like this one. The Food Safety and Inspection Service announced that it will be “mobilizing a stronger, and more comprehensive effort to reduce Salmonella illnesses associated with poultry products.” Their current goal is to “support future action” and move closer to the national target of a 25% reduction in salmonella illnesses. They’ve admitted in a press release this past month that their current policies are not working and it may be time to rethink their approach. 

The inability to control this growing problem in the poultry industry is startling and disappointing but there are things we can do as a consumer to safeguard ourselves and our families. Some guidelines you can follow at home include isolating your raw meat during food preparations and washing your hands often when you prepare any raw meat. Also, cook your meat until it reaches an internal temperature of at least 165F throughout but especially in the largest, thickest parts of the meat. Also, check the Salmonella rates of the plants that source your chicken. We are including a resource for that last step below. While you never know the state of the kitchen when you eat out, it’s also a good idea to check the inspection ratings of your favorite dinner spots. Lastly, as always, if you know or find a local chicken farmer or responsibly sourced butcher shop, support them with your business! Chances are you will have a much easier time talking to them about their health practices than gaining traction with a commercial plant.

Sodium Nitrate: A Pink-tinted Warning

Do you love meat? A burger or a hot dog on a hot summer day? Bacon and eggs a classic morning breakfast? Maybe you’ve noticed your favorite brands of processed meat adding things like, “Nitrates free” or “No nitrates added” to their labels. Maybe you’ve wondered what that means and why it is important. Here’s what you need to know to understand what those labels really mean. 

Sodium nitrate is a common meat additive that is also used in explosives, glass and fertilizer. It is used in cured meats as a preservative but notably it is used to produce the pink color we are used to associating with our processed meats. Have you ever thought that it was odd that a chunk of fresh ham or beef was pinkish, light brown especially when cooked but somehow a hotdog (fully cooked as well according to the packaging) was still a bright, two-shades-down-from-pepto pink? Sliced ham as well is known for that pink, deli meat vibe and would be virtually unrecognizable if it were light brown instead. This is mostly due to sodium nitrate and it is a big reason despite the nutrition and science communities’ misgivings of the last three decades, it is still used in curing processed meat today. 

Now, you may be ready to point to my earlier statement about your “No nitrate added” label and say, Why is this even a concern if nitrates are being left out of processed meats today? Unfortunately, the truth is a little more complicated. Synthetically derived nitrates are in fact limited in meat today and a lot of companies are touting “no added nitrates,” as the weight of the evidence shows that nitrates may be linked pretty closely to a few very deadly forms of cancer. The sticking point is that nitrate can also be and is derived from celery, a natural source that isn’t regulated in the US. Now, you might think that because celery is natural, there is no issue? The difference is that when you eat celery, there is a balance of nutrients that keep any small amount of celery from forming the same pre-cancerous cell stimulating nitrate variants that synthetic nitrates promote. This balance is destroyed, however, when celery is processed into a concentrated powder and used as a preservative. Because celery powder is not regulated in the US, it causes the same issues as synthetic nitrates and meat producers do not have to explain that. They can claim that something is “all natural” and that there are no added nitrates even while adding and using celery powder which health-wise is just as detrimental. 

So, if you are a lover of meat and frequently enjoy processed meats like hotdogs and bacon, keep in mind that more than likely, you are still consuming the cancer linked nitrates health conscious scientists have been warning about for over 20 years. Most health professionals aware of this issue suggest reducing your meat consumption altogether. Additionally, similar to sourcing fruits and veggies, the closer you can get to a privately owned rancher or responsibly sourced butcher shop, the better!

Cortisol: The Stress Police

Cortisol floods the body during times of intense stress and is key in regulating metabolism and blood pressure. You might think about it as the hormone that controls many of the mitigating systems of the body which allows us to respond to stress. Say you are being chased by someone legitimately scary and you need to run away or make a plan to escape. Cortisol is the chemical that optimises the body for those functions only. Like a plane, going down it pulls resources from other areas of the body and throws them into supporting flight or fight. You get a shot of adrenaline if you need to run and the digestive, reproductive and growth systems and processes are dialed down. Your fear and motivation based brain functions light up and you are ready for combat. 

Now, normally, once the danger has passed, cortisol will be released less and the levels with the body will return to normal and life goes on. Now imagine your cortisol levels remained high. Your bodily processes geared towards functions that don’t support fight or flight would still be suppressed and your adrenal glands would continue to be triggered. Adrenaline is driving up blood pressure and in the long term would probably cause an increase in weight and could even contribute to heart disease.

Cortisol secretion is handled by the HPA axis, which is made up of the hypothalamus, the pituitary gland and the adrenal gland. High cortisol levels can be caused by a wide variety of things. For women, one of the most common causes seems to be a high level of circulating estrogen. High levels can also be caused by tumors on the pituitary gland or the adrenal glands. This is often common in Cushing syndrome which is a disorder characterised by higher than average levels of cortisol. Symptoms of this disease include weight gain around the midsection, a fatty hump between the shoulders, a rounded face and pink or purple stretch marks. If you have these symptoms, you should check in with your doctor to get a formal diagnosis as any grouping of these could be attributed to a wide variety of other things. As always, this blog is for informational purposes only, not diagnosis. 

If you suspect that your cortisol levels may be a bit unbalanced, see a doctor. Additionally, make sure you are supporting your health in all the foundational ways we’ve discussed in previous articles. Make sure you are getting enough good quality sleep. Stay hydrated and eat a nutritious diet.  Caffeine stimulates the production of cortisol so perhaps reducing the number of days you start with a cup a joe would be best along with reducing stress in general. Exercise regularly and make sure you are getting the omega fatty acids you need! Things like meditation and yoga are often helpful in mitigating a stressful schedule and therapy can help you learn tools to cope with long term or historical stressors as well!

Chocolate, Health & Healthy Chocolate

You’ve probably seen the jokes floating around that go something like, “I want a salad…but a salad that is mostly tomatoes and cheese, no lettuce, on a really, really big crouton. A pizza…I want a pizza.” Or, “chocolate comes from cocoa, which grows on trees so it’s basically a fruit. Chocolate is a fruit salad.” While these memes might stretch the truth a little bit, chocolate at least should not be relegated to the junk food pile just yet. 

Chocolate or more specifically the cocoa chocolate is made from, is linked to a reduction in heart disease and lower blood pressure. It contains many bioactive components like vitamins, minerals, polyphenols and fatty acids. It is also supportive of mental health and has been documented to improve the mental state of expecting mothers. One article stated that because there is a high level of flavanols in chocolate, it has antiallergic, anti-viral, anti inflammatory and anticancer properties. It even reduces the chance of a woman developing type 2 diabetes by reducing their insulin resistance. It would seem that the benefit of chocolate is more significant for people assigned female at birth, possibly because of their hormonal makeup or maybe some other feature we don‘t totally understand yet. 

Historically, chocolate was used in many cultures for its medicinal purposes and was even referred to as the “food of the gods”. With Nestle and the introduction of ingredients like condensed powdered milk and large amounts of sugar, chocolate’s common usage as a medicine started to see a significant decline. 

Polyphenols could have a discussion all their own but the presence of their flavanols subset in chocolate pushes chocolate into an almost superfood tier when it comes to cognitive function. In fact, one study made their entire purpose to figure out if chocolate consumption in a country resulted in a higher cognitive function on average for that country! They did this by taking the chocolate consumption for the country and examining it with regard to how many Nobel laureates there were in each country. The results supported the hypothesis that chocolate consumption enhances intelligence. 

As you might imagine, milk chocolate yields less of these beneficial characteristics and white chocolate isn’t really chocolate in the strictest sense. The addition of milk and sugar undercuts a lot of the benefits so if you are eating chocolate for your health as well as your enjoyment, dark chocolate, minimally processed, is the way to go.
