Superfoods are full of good nutrition. They are important for health and well-being. Everyone knows about salmon for heart and muscle health and blueberries for your brain. So I skipped over these and included 10 other foods you should include in your diet:

Kefir

Kefir is a tangy cultured milk product made by fermenting milk with several bacteria and yeasts. Kefir tops the list of superfoods because it is rich in beneficial bacteria called probiotics. Probiotics are good for gut and immune health. Kefir is an excellence source of calcium and vitamin D for bone health and several B vitamins (your energy vitamins). Opt for plain kefir or mix a little flavored kefir (generally high in added sugars) with plain kefir for great taste but less sugar. If you are lactose intolerant kefir is easier on the stomach because enzymes in the bacteria help break down lactose.

Other Options: Though most yogurts don’t contain the wide variety and number of probiotics as kefir, they are a great option as well. Other probiotic-rich foods include: unpasteurized sauerkraut, miso soup, naturally fermented pickles, and good quality sourdough bread.

Beets

Beets come in brilliant shades of dark red, yellow and orange and have a nice sweet earthy flavor. They are a good source of potassium for nerve and muscle functioning as well as healthy blood pressure. Beets are also a good source of vitamin C and fiber. Beets have more nitrates than most other foods. Nitrates help the body make nitric oxide, a gas that expands blood vessels to make room for greater blood flow. Regular intake of high nitrate foods can help lower blood pressure and improve blood vessel functioning. If you drink 16 oz. of beetroot juice (containing 300-500 mg of nitrates) 2.5 – 3 hours before you hit the gym, you may notice a bump in energy thanks to greater blood flow to working muscles. There’s one caveat: antibacterial mouthwash kills the good bacteria in your mouth. This bacteria is needed for the first step in nitric oxide production. Some research suggests antibacterial mouthwash may increase blood pressure and raise heart disease risk.

Other Options: Celery, argula, spinach are good sources of nitrates.

Ginger

Ginger soothes an upset stomach and helps ease symptoms of motion sickness. Make ginger a regular part of your diet and you’ll also benefit from its ability to decrease muscle soreness after tough bouts of exercise.

Other options: Combat excess muscle soreness with tart cherry juice.

Sunflower seeds

One serving of sunflower seeds will help you meet one-half of your daily vitamin E needs – a nutrient that most Americans aren’t consuming in recommended amounts. Vitamin E protects your cell membranes (including muscle cells) from damage, supports immune functioning and helps expand blood vessels to accommodate greater blood flow. Vitamin E deprived muscle cell membranes do not heal properly yet a healthy balance is important. Get enough, but not too much, of this vitamin as both deficiency and excess may impair your training gains. Plus, more than recommended amounts will not improve athletic performance.

Other Options: Snack on almonds, pine nuts, and peanuts to help you meet your vitamin E needs.

Pumpkin seeds

Pumpkin seeds are one of the best sources of magnesium, a mineral that is so widely under-consumed. Magnesium keeps muscles and nerves functioning properly and is also necessary for your body to produce energy. Pumpkin seeds are also an excellent source of zinc, a mineral important for immune health and wound healing.

Other options: Sesame seeds and Brazil nuts are also excellent sources of magnesium. For a magnesium-packed meal, brush firm tofu (also a source of magnesium) with sesame oil and coat with sesame seeds before stir-frying.

Olive Oil

Olive oil is a staple in Italy and Spain where the Mediterranean Diet is associated with reduced risk of cardiovascular disease, cancer and improved brain health. Replacing dietary saturated fats, such as butter or shortening, with olive oil may help reduce risk of coronary heart disease. Replacing other cooking oils with olive oil may help lower blood pressure and improve blood cholesterol. Use olive oil in moderation, because it is high in calories. There are some sketchy companies out there who mix cheaper quality oils with olive oil to lower their costs. Make sure you’re getting good quality olive oil by looking for a seal of approval from the USDA Quality Monitoring Program or the North American Olive Oil Association (NOOA).

Other Options: For baking, cooking, stirfrying and other high heat cooking, consider almond, hazelnut, peanut, or pecan oil.

Garlic

Garlic adds favor without calories. When used in a marinade or added to beef, fish, chicken or turkey patties, garlic helps limit the formation of nasty compounds that cause cancer in animals, heterocyclic amines (HCAs). HCAs are formed when your protein-rich food is cooked. High dry heat leads to more HCAs formed so make sure you add garlic to any meat, poultry or fish you throw on the grill or in the smoker.

Other Options: Rosemary and Caribbean spices also decrease HCA formation.

Dark Chocolate, one of the Ultimate Superfoods?

Wouldn’t it be great if you could bite into a rich, smooth, dark piece of chocolate with complete confidence that you were doing something good for your body? Dark chocolate is made from cocoa powder – the defatted powder from cacao beans. Cocoa powder contains flavanols, a group of antioxidants responsible for the association between dark chocolate and lower blood pressure. Unfortunately you can’t rely on the percentage of cocoa or cacao in a bar as an indicator of total flavanol content. Here’s your best option for  getting that dark chocolate taste you are craving and health benefits as well.

Tempeh

In your local grocery store, tucked in a remote refrigerator between tofu and non-dairy “cheese,” you’ll find long, thin light brown colored sheets of tempeh. Tempeh is fermented soybeans. Unlike tofu, tempeh includes the whole soybean so it is higher in protein, fiber, and vitamins. Tempeh is also an excellent source of iron (for oxygen delivery throughout your body), magnesium and vitamin B-6 (an energy vitamin) and good source of calcium.

Tempeh has a firm, chewy texture and slightly earthy, bean-like taste. Replace deli meat with tempeh, try it sautéed in sesame oil and garlic, grilled or served on top of salad.

Other options: Pick up plan or flavored tofu.

Green peas

Green peas are so ordinary. Why did I add them to the list of superfoods? Green peas are an excellent source of fiber and vitamin C, good source of vitamin A (important for your eyes and a “nutrient of concern”) and also contain decent amount of magnesium, vitamin B6, folate (a “nutrient of concern,” folate helps build healthy new cells and prevents some birth defects) and iron. Look for pea protein in bars and protein powders. It boosts a leucine (the key amino acid that turns on muscle building and repair) content equivalent to whey protein and will give you the same muscle-building results as whey protein.

Try peas in multiple forms including pea protein powder, split pea soup and peas mixed into burritos, wraps, in other dishes. Add peas to your rice pilaf, pasta dish, casserole, or stew.

Other Options: Consider yellow whole or split peas. They have a similar nutrition profile to green peas.

Superfoods add vitamins, minerals, fiber and plant compounds important for good health. They support your daily energy needs while improving your overall health.

Fuel Your Child for Learning More this School Year

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

Kids learning potential skyrockets when they are healthy from head to toe. This school year, support your child’s growth, development and learning by following these 3 tips each day:

Bank on Dairy

From celebrity websites and diet books to popular Instagram feeds and “clean eating” blogs, its trendy to ditch dairy. Yet experts say going dairy-free has multiple downfalls – and it may be downright dangerous – especially for kids and young adults. Kids and teens have a limited time period to build bones. A dairy-free diet during these critical growing years could mean a child doesn’t reach Dairy for growth and learningtheir full height potential, they may have an increase in stress fractures during adolescence, and a greater chance of developing the brittle bone disease osteoporosis as an adult. In addition to 9 essential nutrients, including bone-building calcium and vitamin D, the combination of protein and carbohydrate in dairy will help build and fuel active muscles and minds.

Make Fruits and Veggies Fun

Introducing kids to new foods can be both fun and easy. In addition to offering a food multiple times and modeling healthy eating (eating a wide variety of foods in front of your kids), try pairing less familiar foods with ones that are more familiar. Many kids love getting in the kitchen and helping prepare food, especially when it comes to baking. Why not make muffins, bread or even a cake with vegetables in it. Carrot cake, zucchini muffins and avocado cupcakes taste great and  make a child more familiar with these vegetables. Once kids see them again, sautéed at dinner time, baked into a lasagna or  sliced on top of a sandwich, they will be more likely to eat them.

Pack better Snacks for better Learning

As a kid I played hard then lost steam quickly. Luckily my parents let us snack whenever we felt the need to eat. Frequent snacking can help keep children alert and attentive. Pack snacks that please their taste buds while fueling their bodies with nutrients they need for good health. Naturally sweet fresh or dried fruit, trail mix, yogurt, string cheese and nut butter with whole grain crackers are all excellent options that will satisfy your child’s taste buds while providing the nutrients they need for good health.

 

 

 

Get Cultured: Probiotics can Help You Lose Weight & Stay Healthy

From Greek to Icelandic Skyr, yogurt is everywhere. Choose the right kind, one packed with probiotics and protein, and yogurt can help you trim your waistline while supporting overall health at the same time.

In this article, I’m covering:
• How gut bacteria influence your weight and health
• Probiotic-rich foods for health & healthy weight

Your Gut Bacteria Influence Your Weight & Health

There is an entire community of over one trillion microbes (bacteria) taking up valuable real estate in your gut. Some are good, some are bad and the rest are neutral. The good guys are key players for digestive and immune functioning (remember about 70% of your immune system is located in your gut). They have many other functions as well:
bacteria, probiotics and body weight

Research studies show lean and obese people have a different makeup of bacteria in their gut. In addition, lean individuals have a greater diversity of bacteria in their gut. Diversity is important –  think of bacteria like a team of people each one has a different job and they work better together than in isolation.

If an obese person loses weight their overall makeup of bacteria more closely resemble’s a lean person’s gut. Greater weight loss = even greater the changes in gut bacteria. Also, changing bacteria seems to influence weight, though scientists know less about the influence of altering gut bacteria and changing body weight. Lean mice transplanted with bacteria from obese mice experienced a 60% increase in body fat without changing their food intake (calories in) or physical activity (calories out). The authors of this study believe the change in gut bacteria resulted in an increased absorption of some carbohydrates, increase in the production of fat and increase in fat storage. Authors from another study, this one examining human twins, also found a connection between types of bacteria in the gut and body weight, particularly visceral fat – deep layers of fat that coat the organs and are tied to higher risk of certain chronic diseases such as heart disease. The authors of this study believe, like the study in mice, obese individuals may be absorbing more calories from the food they eat.

Probiotic-Rich Foods for Health & Healthy Weight

How did they swap out bacteria in studies? Poop transplants. This isn’t exactly something you should try at home. But there’s another, easier way to keep your gut healthy. Get cultured by picking up foods that contain healthy bacteria including yogurt (with live and active cultures), kefir (drinkable yogurt, it’s so good!), miso soup, homemade sauerkraut, and tempeh (made from soy, this has a nutty taste). There might be something special about yogurt – a meta-analysis (a study that combined the results of other studies) looked at dairy intake and weight changes over time. They found greater yogurt intake was associated with lower body weight. Plus the protein in Greek yogurt seems to help people feel full so they eat less at their next meal. Also, feed the bacteria by eating plenty of fruits, vegetables and whole grains, particularly onions, greens, beans, legumes, berries and bananas, to get enough prebiotics (food) to support their growth.

Yikes! Are there Antibiotics or Hormones in Your Milk & Dairy Foods?

milk

Are antibiotics and hormones used in dairy cows contributing to the obesity epidemic, early puberty and antibiotic resistance? Before going down that road, we have to first we have to first ask if there are any antibiotics or hormones in milk and dairy products.

In this blog post I will cover:

  • Why are antibiotics given to cows?
  • Antibiotics are not in milk, here’s why.
  • Why are growth hormones given to cows? Are there any hormones in my milk and dairy food?
  • What are the cows Eating?

Why are Antibiotics given to Cows?

Antibiotics are used on farms to treat animals who are sick just like you would give an antibiotic to your child if he or she gets sick or take one yourself. There is no reason for dairy farmers to give antibiotics to cows who are not sick. Doing so costs additional money,  serves no clear purpose and arbitrarily giving animals antibiotics could contribute to antibiotic resistance. Now imagine you are a farmer and your life depends on the health of your cows – would you want to run the risk of antibiotic resistance and your cows getting sick with fewer treatment options?

Some antibiotics are also used for animal growth. The FDA is phasing out this practice so medically important antimicrobial drugs (antibiotics) will no longer be allowed to enhance growth or feed efficiency. In the future antibiotics will only be allowed to treat, control or prevent disease and of course require a prescription from a licensed veterinarian. Regardless of whether or not the antibiotic is used for growth or treatment of disease, no traces of antibiotic residues are allowed in milk or dairy products.

Antibiotics are Not in Milk, Here’s Why.

Any cow that gets an antibiotic is milked separately from the rest of the herd and the milk is thrown out. That milk will never be sold or consumed. All antibiotics have a different period of time before all traces of the medication leaves the body (whether we are talking about a cow or a human). Once this period is up and the cow is completely healthy again, the farmer tests her milk. Milk cannot be sold until it is completely clear of all drug residues. Whether organic or conventional, all milk is tested several times before making it to market. It is tested on the farm and at the milk processing plant. Any milk that tests positive for any medication residue, including antibiotics, is thrown out (1).

According to national Milk Drug Residue Data Base compiled for the years 2013 to 2014, 0% of milk tested positive for drug residues. In 2015, the FDA’s Center of Veterinary Medicine surveyed 1,918 raw milk samples (before pasteurization) from across the country. Samples were tested for residues of 31 drugs including the antibiotics, NSAIDs (ibuprofen etc.) and an antihistamine. They found 99% of sampled milk was free of any drug residues. Keep in mind the 1% of milk with residues must be thrown out – it cannot be sold (1, 2).

Cheese and yogurt are made from milk and therefore, there are no antibiotics in your cheese or yogurt either.

If you want to learn more about what farmers are doing about antibiotic resistance, Minnesota Farmer Wanda Patsche wrote an excellent blog on this topic.

Growth Hormones in Dairy Cows

Growth hormones are approved for use in dairy cows to improve milk production. Greater milk production means fewer environmental resources used to raise cows for milk. Bovine somatotropin (bST; also called bovine growth hormone or rBGH) is perhaps the most well recognized growth hormone used on dairy farms. bST is “a protein hormone produced in the pituitary gland of animals, including humans, and is essential for normal growth, development, and health maintenance.” Very little bST is used in dairy cows and there is no test that can distinguish between cows treated with bST and naturally occurring bST (3). Humans do not have receptors for bST and therefore it is passed through your body intact without being absorbed (4). As a result, there are no known side effects or health issues associated with consuming dairy from cows treated with bST. IGF-1 (insulin like growth factor 1) concentrations are slightly higher in cows treated with bST. However, the human body synthesizes IGF-I and drinking 1.5 L of milk is equivalent to an estimated 0.09% of the IGF-I produced by adults each day (5, 6, 7, 8).

USDA organic dairy products are “produced without antibiotics fed or administered to the animal at any point in its life” (9). There are no meaningful nutrition differences between organic and conventional dairy products. I covered that topic in this post.

What are the Cows Eating?

Cows’ diets also vary depending on many of the same factors that influence your food choices. However, unlike humans, all cows have the benefit of seeing a nutrition expert (like dietitians, animal nutrition experts are specialists). Many consumers also have questions about how cows are fed. Cows are fed nutritious diet to ensure health of cow and nutrition of milk. Typical feed mixtures may include haylage (grass with a higher water content), corn silage, sugar beet pulp and a protein mineral mix.

Rest assured, your dairy products are safe. In fact, the dairy product that says it is made with cows not treated with antibiotics is the exact same as the one from a cow that may have been treated with antibiotics. Both contain no antibiotic residues. Growth hormones used in dairy also pose no known threat to human health. The human body does not even recognize the main hormone used in cows. So, regardless of what milk, yogurt, or cheese you choose, all have been produced and extensively tested to ensure they are safe for human consumption.

Full Fat or Low Fat Dairy?

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

If you are totally against low-fat dairy, it’s time to take a closer look at the research. After listening to this dairy debate and watching the finger pointing, I started searching through the literature for an answer to this question “does dairy fat increase LDL cholesterol and risk for cardiovascular disease?” Then I came to my senses. No one eats dairy fat. Unless you’re a food scientist, you aren’t separating the fat from milk or full-fat yogurt and eating it or adding it as an ingredient to your recipes. However, we do eat cheese and yogurt and drink milk. The array of compounds in each of these foods influences how they affect your cholesterol and risk for heart disease. So, I revised the question to: “how does full fat cheese, yogurt and milk impact cholesterol and risk for heart disease?”

Here’s what I’ll cover in this article:

  • Why people are up in arms about saturated fat – saying it is either good or bad;
  • How does full fat cheese, yogurt and milk impact cholesterol;
  • What should you do with this information?

Dairy Fat isn’t the Only Factor

The research on dairy generally follows the research on saturated fat: the replacement strategy matters. For instance, it isn’t a good idea to take cheese out of your diet and replace it with a highly refined carbohydrate (not a good move for blood fats). Butter isn’t better than liquid oil. Butter raises LDL cholesterol. Some research suggests dairy fat might raise the large, less artery clogging LDL cholesterol compared to small dense LDL. However, “less artery clogging” does not mean “not artery clogging” and this area of the science needs more work before we can draw firm conclusions. Also, there are a few differences based on the type of food (milk, cheese, yogurt, butter); aged cheese reigns.

dairy and cheddar cheese

-> Aged cheese does not raise LDL as much as butter (accounting for total fat in each). In fact, several studies show aged cheese appears to have a “relatively minor” impact on LDL cholesterol or no impact at all. This could be due to the calcium content, which leads to the excretion of some fat or, fermentation may have an effect. Aged cheese stands out in the research.

-> Yogurt appears to have less of a cholesterol raising effect than expected. However this research is inconsistent possibly due to differences in the type of bacteria in the yogurt (aka probiotics). I recommend choosing yogurt with “live and active cultures.”

– > Milk – when consuming the same amount of fat from whole milk or butter, both raise LDL to the same extent. Milk contributes substantially less total fat per amount consumed compared to full fat yogurt and butter. Cross-sectional studies suggest milk consumption doesn’t raise coronary artery disease risk, however, this may reflect lower total fat intake from milk compared to butter.

-> Cottage cheese –  this incredible food is oftentimes forgotten yet an excellent addition to your diet. I couldn’t find any studies on cottage cheese, however, the highest fat cottage cheese I could find  (4% milk fat) contained 5 g total fat per serving so we can expect the impact cottage cheese may have a lower impact compared to whole milk.

What Should You Do with this Information?

If your LDL is high, choose skim, 1% or low fat milk. Opt for a good quality yogurt with naturally occurring probiotics. As far as cheese goes – I’d take out all of the other offending foods and work on other aspects of heart health before ditching the cheese (unless your LDL is very high) and cottage cheese. However, always follow the dietary advice of your registered dietitian since there are many variables that should be taken into consideration.

What about the trans fats in dairy? They are good for you right? No. In large amounts, the trans fats in dairy have the same impact as those found in partially hydrogenated oil (not good for cholesterol, cardiovascular disease risk etc.). However, we don’t eat dairy trans fats in significant quantities (they make up very tiny amounts of dairy fat and beef fat).

Take Home Points

In general, dairy foods help lower blood pressure plus there is emerging evidence about the positive role dairy foods may play in metabolic syndrome. What about dairy fat? Consider the whole food and your diet overall so you can make the right choices based on your personal risk factors for cardiovascular disease. Also, keep in mind there are many factors that influence cardiovascular disease pathology, some of which are unrelated to cholesterol.

The Truth about Detox Diets

Detox Diets and Cleanses

Detox diets promise to clean up the mess left behind from daily life so you feel better, more energetic and lose excess body fat. Consider them the Merry Maids for your body. They come with an army of equipment and compounds to attack years of buildup from environmental toxins, pesticides, allergens, waste, and inflammatory substances. This “sewage sludge” is stuck to your gut, interfering with digestion, leaving you bloated, tired, fat and with joints and muscles that feel like they are on fire.

In theory this sounds great. But there’s one glaring issue. The human body doesn’t need to “detox” because it comes equipped with organs designed to remove waste products. Plus, many detox diets are simply very low calorie plans with added laxatives and diuretics (because instant, yet temporary, weight loss might fool you into believing the outrageous claims on detox and cleansing products). Instead of wasting your money, take the top 3 good points about many of these diets and incorporate them into your overall nutrition plan:

Drink More Water

There are a few studies showing that individuals who are obese can lose weight by drinking 2 glasses of water before each meal. Plus, many people don’t get enough water or total fluids each day anyway and dehydration can make you feel sluggish and grouchy. So, grab it from the tap or if it’s more convenient, fill up your stainless steal water bottles and carry them with you at all times.

Eat More Fruits and Vegetables

The average American is falling short on fruit and vegetable intake. According to the National Cancer Institute, people with diets rich in plant foods, such as fruits and vegetables, have a lower risk of getting some types of cancer as well as diabetes, heart disease and high blood pressure. Produce generally has fewer calories than many other foods making it a great addition to a weight loss diet.

Get Friendly with Bacteria

Many detox plans include unfiltered apple cider vinegar – the kind that has a cloudy appearance – is full of probiotics. Probiotics are friendly (beneficial) bacteria – the kind that live in your gut and have a number of important functions in your body. Improving your gut bacteria may support immune functioning, improve the health of your intestinal tract, increase your body’s absorption of certain nutrients and alleviate constipation. Apple cider vinegar is acidic so I don’t recommend drinking it straight. Instead, dilute it in a big glass of water or another beverage. Other great sources of probiotics include kefir, yogurt (check the container for “live and active cultures”), miso soup, tempeh, sauerkraut, kimchi.

Add 2 glasses of water before each meal, load up on vegetables and fruits and make an effort to consume probiotic-rich food daily and you will reap the rewards of better nutrition without wasting money on detox diets and cleanses.

I get quite a few questions from parents who ask what they can feed their kids to keep them fueled for sports yet happy at mealtime. After all, no parent wants to hear their child complain at mealtime (or stubbornly sit at the table for hours like I did, refusing to eat my peas). So expert dietitian Leah Holcombe put together this fantastic document with several ideas for kid-friendly lunches.
