GREEN IS THE THEME

Oh yeah, y’all — St. Patty’s day! Now, in the spirit of celebrating this most festive of holidays responsibly, here are some topics on how incorporating more “green” in our lives will allow us to eat healthier, celebrate conscientiously, all while helping out our mother earth.

St. Patty’s Day Fun Fact

St. Patrick was actually of Scottish descent, not Irish, and contrary to popular folklore he never chased any snakes out of Ireland.

Environment

Have you heard of “Carbon footprint”? Well in short, it is a measure of the impact our activities have on the environment, such as transportation and production. Researchers atCarnegieMellonUniversityhave suggested that it is not so much the “food miles” but more so the dietary choices that we make.

Now, by changing only one day per week’s meat and dairy-based calories to chicken, fish or vegetables would have about the same impact. Also, shifting entirely from an average American diet to a vegetable-based one would reduce the same emissions as 8,000 miles driven per year. By no means am I trying to convert you to a vegetarian, but if you are looking for suggestions to help mother earth out while still following a balanced diet, then pull back on red meats & dairy, and increase your chicken, fish and veggies. Maybe the cows that work for Chik-Fil-A are on to something.

Power of Leafy Greens

What if I told you that by consuming this item, it will help you lose weight, prevent cancer, regulate digestion, maintain eye health, boost your immune system, increase bone strength, and has anti-aging properties! Interested???

Leafy greens contain high levels of dietary fiber, magnesium, potassium, folic acid, calcium, vitamins A-C-E-K and phytonutrients. Look for favorite recipes that include bok choy, spinach, broccoli, collar greens and lettuce.

Green Antioxidants

Green tea…The Cancer Fighter and them some! Well, at least some recent research has shown for this to be true. One study demonstrated showed a lower recurrence of cancer in women with stage 1 & 2 breast cancer after surgery. Other studies included a reduced risk of developing lung cancer by 18%, a reduced prevalence of clogging the heart’s blood vessels (especially in women), and also that green tea antioxidants fight obesity and lowers LDL cholesterol. Many of these studies come from our friend across the pond, where green tea and the consumption of fish and soy proteins is more prevalent .

No matter what side of the pond you live on, there is no denying that green tea has antioxidants (catechins) and compounds that scavenge for free radicals that can damage DNA and contribute to cancer, blood clots, and atherosclerosis. All these great benefits and only roughly 30 mg of caffeine.

March is also National Nutrition Month

The campaign, celebrated by all Dietitians and created by the American Dietetic Association, is designed to focus attention on the importance of making informed food choices and developing sound eating and physical activity habits. Also notably, March 9th is RD (registered dietitian) Day…so help celebrate a dietitian near and dear to you.

BLUEBERRIES

Good source of: Vit. C & E, manganese, fiber, antioxidants, and phytochemicals

Works to: neutralizes free radicals, strengthens blood vessels, stabilizes collagen matrix, improves vision and reduces the risk of macular degeneration (ARMD), improves brain functioning reducing the risk for dementia and Alzheimer’s disease, improves learning capacity, lowers cholesterol, fights cancer, improves gastrointestinal functioning, and prevent urinary tract infections

FLAXSEED:

It is very high in omega-3 essential fatty acids – yes, the good fats. Omega-3 fat is referred to as an “essential” fat because it is not produced by the body, and must thus be consumed. Essential fats aid in lowering cholesterol, stabilizing blood sugar, lower the risk of certain cancers, and reduce the inflammation of arthritis, as well as the inflammation that accompanies certain illnesses such as Parkinson’s disease and asthma.

In addition to the omega-3s, the other components of flaxseed, namely lignans and fiber, are extremely beneficial on the health measuring stick, as well.. Both act as phytoestrogens and antioxidants, while the fiber contained in the flaxseed is of both the soluble and insoluble type.

CRANBERRIES:

Whether you drink cranberry juice, blend cranberries in smoothies, add cranberries to stuffing or enjoy cranberries in salsa, salads or side dishes, they can keep you healthy any time of the year. They are loaded with Vitamin C and other antioxidants.
Their crimson color comes from a flavonoid that may help lower your LDL- (bad) cholesterol, help prevent blood clots that cause heart attacks and strokes-and so protect you from heart disease. Their other plant substances may protect from cancers, gum disease and stomach ulcers.
Another better known benefit, substances in cranberries help prevent bacteria in the urinary tract from causing bladder infections.

YOGURT especially Greek yogurt, is a great source of both protein, and good carbs. Yogurt is also packed with a good source of calcium, great for healthy bones and thus reduces the risk of osteoporosis.

March 2023 Newsletter

Published on

Its March already, y’all!! March is also National Nutrition month.

So the key to achieving optimal health cannot be found in any one food, drink, pill or machine, but rather through commitment to healthy lifestyle behaviors, focused on maintainable and enjoyable eating practices and daily physical activity.

Therefore I am taking the opportunity in this newsletter for some tips to hone in on the “low hanging fruit” (pun intended.) In other words, list of principles for a healthy lifestyle.

Get in touch with your Requirements: Factors that individualize one’s metabolism include: age, gender, body type, family history, existing health conditions and daily routines. Finding foods that work simultaneous to your needs based on nutrient density (foods with lots of nutrients but lower in calories eg. Fruits and veggie) versus calorie density (foods with more calories but lower nutrients (eg candy, bread, refined flour-based) will make you feel more satisfied, hence reduce mindless eating.

Get in touch with Food Facts. Whole foods compared to packaged/processed food is evident in the ingredient list on a food label, enabling optimal choices. The higher an ingredient is on the list, the more of that ingredient is included compared to others. This is a good way to determine if a product is made with whole grains, or has a lot of added sugars. Nutrition claims on the front of a package, are often more about the marketing, versus the facts.

Plan ahead especially snasks. Reduce temptation by keeping a variety of tasty, nutritious, ready-to-eat foods on hand. Furthermore, this makes it very easy to avoid vending machines, convenience stores, or the break room. Healthy snack ideas include fresh fruit, air-popped popcorn, healthy crackers, nut mixes, almonds and Greek yogurt. Think of snacks as mini-meals to help you eat more whole foods, and less at breakfast, lunch and dinner.

Get in touch with mindless eating: Become aware of hunger and satiety cues and compare them to habits of boredom, stress, or frustration and when food seems to be the solace to calm these emotions. Immediate satisfaction lands up being chronic struggles with optimal health down the line. A great way to accomplish this is to keep personal notes and simultaneous food logs to find patterns and triggers, if you feel inclined (of course emotional diaries/logs are not everyone’s cup of tea.)

Incorporate Movement: Daily physical activity is an important part of a healthy lifestyle, but unfortunately often easier said than done. Regular physical activity strengthens bones and muscles, reduces the risk of chronic illness, and fosters overall well-being, which included stress relief, higher quality sleep and a more positive mental outlook. The key is to find activities that are enjoyable and can easily be maintained.

Some tips in that regard:

Try using the buddy system, joining a walking group or attending fitness classes.
Sign up for a 5k run/walk with friends or family.
Sneak in exercise at your desk or buy a desk that allows you to stand while working.
Take a short walk on your lunch break Walk up and down the stairs when the weather’s bad.
And again: track daily movement, such as keeping a journal, using a website, or tracking devices such as fitbits, garmins, apple watch (lots and lots of apps these days)

March is also a month we think of St. Patty’s Day so with that said – POWER OF GREENS, LEAFY GREENS NONETHELESS:

How to Keep a Food Journal

Published on

The number one complaint about keeping a food journal is that it is too much work for your busy schedule or that it makes you think more about food. Both of these are probably true. In the beginning, however, driving a car was a lot of effort. Eventually it became second nature and now you can probably drive while eating. By using either of these tools you can also update your food journal while in your car. (not while driving of course )

Keeping a food journal will help you improve your eating habits. No doubt about it. You can’t manage what you can’t measure. It is an old management adage that is just as meaningful to your weight control. Unless you measure something you don’t know if it is getting better or worse. If we are going to be able to help you with your weight management, we need to be able to see what you are eating and when you are eating it. SO.. we are going to do this thing, let’s make it as easy and fun as possible.

There are various apps on-line that regulate your fitness and food journal. They typically let you track what you eat with a few clicks – almost no data entry and record your workouts in minutes. Some examples are FitBit, MyNetDiary, Livestrong, MyFitnessPal, etc.

TweetWhatYouEat is another on-line food journal – stripped down to the bare necessities. If you use Twitter, this is incredibly easy to use. You sign up with the service and then, using your Twitter account, send a direct message every time you eat something. Like this:

DM TWYE 2 eggs, spinach, olive oil

That’s it. When you go to your TWYE diary, you will see a list of everything you entered. The calorie counts are “crowdsourced”, meaning that other users have given “2 eggs” a calorie count and TWYE uses that in your calculation. If you don’t like the calorie count they used you can edit it. TweetWhatYouEat gives you a total for the day.

You can use either of these services to send food logs to your nutrition clinicians, or merely just for self accountability.

If you use Twitter, feel free to follow me on Twitter for our latest tips @ilanakatz. I try to post neat stuff to share with Twitter friends frequently. Or of course Facebook too “Optimal Nutrition for Life – by Ilana”.

Hyponatremia: Signs, Symptoms and Warnings

Published on

Ilana Katz MS, RD, CSSD

Hyponatremia tends to be mostly associated with athletes who participate in long duration sports such as marathons and triathlons. Endurance athletes taking in water during training or an event can develop hyponatremia, a potentially life threatening condition that occurs when sodium levels drop to a dangerous low in the blood stream (below 135 mmol/L (of blood). Early symptoms may include nausea, drowsiness, confusion, headache and fatigue. These can quickly progress to seizures, coma and death if not resolved in time. Importantly, athletes are not the only population that needs to be aware of this deadly phenomenon.

Dilution of sodium can result, as mentioned, from over-drinking, but also from water retention (often a side effect of various medications). Sodium can be lost in various ways other than dilution which include urination, perspiration and gastrointestinal distress (vomiting/diarrhea). Furthermore certain medical conditions such as congestive disease, kidney dysfunction and ineffective ant-diuretic hormones are known causes.

Since hyponatremia has usually been associated with endurance sports, those who engage are much more well-informed than in the past, and emergency staff who treat athletic stress conditions are also far better educated to recognize and manage symptoms, and even play a role in prevention. The sports medicine community has been helpful in raising awareness about risks and signs of over-hydration. However, with obvious evidence that there are many other populations at risk for hyponatremia, it is vital to recognize these so that all health care professionals are on the leading edge of avoidance and if necessary, acute care.

Some examples of patients who may be eligible for high alert:

Psychiatric patients with a syndrome known as psychogenic polydipsia, meaning they drink excessive amounts of water..
Multi-pharmocological patients (especially elderly). Why, well because many medications have potential risks.
- Diuretics deplete electrolytes, including sodium
- Antidepressants increase level of antidiuretic hormone
Patients being administered intravenous hypotonic fluids: hypotonic fluids contain a lower concentration of sodium than blood and thus excessive quantities at high entry rate can dilute sodium.
Tube fed patients: proper fluid levels and electrolyte balance must be continuously monitored and orders adjusted based on results of consistent blood work.

There is also the all controversial sodium debate to consider. Researchers and health practitioners often have opposing arguments as to whether dietary sodium should always be strictly conserved. While lowering sodium is unarguably beneficial for those already diagnosed with hypertension (high blood pressure), increasingly conservative recommendations for the average population is often contested. The argument being that too little sodium can lead to other health problems, the main one being hyponatremia. Interestingly, the dietetic community are in agreement that avoidance of dietary sodium is unlikely to cause hyponatremia. Even a very low sodium diet of 500 – 1000 mg/day should maintain adequate levels under normal circumstances. It is the complexity of what defines “normal circumstances.”

In summary, with regards to controlling appropriate levels of sodium in the blood and avoidance of hyponatremia, not only athletes should be aware of hyponatremic signs and symptoms. For those with a normal blood pressure, eating patterns and water intake should be developed based on clinical judgement, guidelines and scientific evidence.

Go with your Gut – GI Distress from a different perspective

Published on

Ilana Katz MS, RD, CSSD

Since a big part of my work with athletes involves reducing the risk of Gastrointestinal (GI) distress I thought a different perspective of the GI environment and how to nurture it would be rather informative. The organisms and their metabolic processes themselves, the majority of which live in the colon, are referred to as microbiome and they dramatically effect human health in general, not just for athletism. The microbiome is made up of trillions of microorganisms ranging between bacteria, fungi, viruses, and others., all of which impact the immune system.

The microbiome multitasks between maintenance of immunity, digestion, hormonal and nutrient balance by:

maintaining optimal gut flora (by fighting pathogens and embracing working microorganisms)
activates anti-inflammatory responses¹
uptake of hormones²
detoxifies environmental negatives (such as drugs, chemicals, unnatural “food” items eg. artificial sweetener, sugar alcohols, etc.)¹
synthesizes essential nutrients (particular to the gut are biotin, folate and vitamin K)¹.

Inflammation and digestion, and most other functions mentioned above, differs greatly between individuals, and is mostly influenced by stress, age, past infections (antibodies), gender (and within gender experience of natural birth, breast feeding, etc.), medications, lifestyle habits (smoking, alcohol, etc.). and most importantly, diet³.

It is thus safe to say that almost every chronic (and probably acute too) inflammatory response is affected by changes in the microorganism composition of the gut. There is no blueprint for an ideal breakdown of gut microbiome but the diversity of the microorganisms has shown an increase in symbiosis – the mutually beneficial relationship between them.

Lower level symbiosis results from higher than necessary caloric intake, highly processed foods, saturated fat, refined sugar, and soda (chemicals) whereas microbial diversity and therefore increased likelihood of positive symbiosis result from dietary intakes such as coffee, tea, red wine, fruits and vegetables, nuts and buttermilk.⁴ Stress would be the biggest contributor to low diversity and reduced symbiosis as well as high triglycerides, irritable bowel symptoms (diarrhea) and intestinal inflammation.⁵

In research on dietary effects of microbiome, the summary states that eating plant-based foods and nuts are related to reduced bowel inflammation and aid in healthy cholesterol management⁵. The typical American diet of low earth based nutrients, high saturated fats, high refined sugars and high in processed animal proteins negatively reduces gut microbial diversity, symbiosis and overall gut health.

So what is it about the earthy foods that assist in a positive microbiome? Simply, the content of fiber. Why? Because although fiber is the undigestible carbohydrate for humans it provides the gut microorganisms with essential “food” for them to produce enzymes. These enzymes in turn, breakdown these undigested carbohydrates in process of fermentation.⁶ Fermentations’ end-product is butyrate, the preferred food-source for cells in the large intestines. The healthier cells are then able to maintain the intestinal wall health, reducing risk of other major chronic disease states such as colon cancer, colitis and Crohn’s disease.

Why then are people with a diagnosis of inflammatory bowel diseases (IBD) like Crohn’s and colitis advised to keep their diet lower in fiber? It may be a case of which came first, their dysbiotic colons, or the fact that fibrous foods can cause abdominal pain, bloating, cramping, diarrhea, and obstructions.⁷ Symptoms of IBD could then be reduced by limiting fiber however the vicious circle of health impacted colon and dysbios will ensue. It is therefore in the best interest of a person struggling with GI distress to seek professional help within the dietetic realm to work on tolerance of fiber. Because GI distress should not mean a low fibrous diet, dietitians will often teach such patients to increase fiber progressively, maintain excellent hydration processes and learn new techniques such as juicing, blending, other cooking methods to pre-breakdown tough fibrous skins of earthy produce, and removing completely undigestible seeds.

So far, I have focused mostly on the digestion of fibrous carbohydrates. But when talking about microbial flora it is important to consider that some undigested animal protein lands up in the colon too. Unlike plant based proteins, the fermentation of animal protein does not result in butyrate and the formation of healthy enzymes, instead they are fermented by colonic bacteria and produce potential toxins such as ammonia, and hydrogen sulfide.⁸ These toxins inhibit butyrate formation that would otherwise protect the colon lining from harmful entry of microbial invasion. The toxic gases thus increase inflammation responses further risk GI distress and chronic bowel diseases. Not only do they inhibit the growth of anti-inflammatory bacteria, but they also support the growth of pro-inflammatory bacteria³. Furthermore, hydrogen sulfate results in foul smelling gas, a common side effect of high protein, low fibrous diets. From a dietetic standpoint, if the diet is high in meat, by simply adding a variety of colorful, and fibrous vegetables could reduce the protein fermentation.

In summary, whether you are an athlete looking to reduce the risk of gastrointestinal distress while training/racing, or an individual wanting to reduce irritable bowel syndrome, or just an individual trying to keep the gut healthy, diet is the major factor determining microbiome make-up. The best diet for a healthy flora in the colon is simply a whole food diet with a variety of non-processed macronutrients (fibrous carbohydrates, lean protein and unsaturated fat), favoring plant-based more than animal proteins, non-excessive alcohol (favoring red wine) and the elimination of refined and processed sugars, artificial sweeteners and sodas.
