For years now, a popular dieting book titled, "Eat Right For Your Type," has continued to be a dominant trend for those curious to try a new method of losing weight that focuses on consuming foods that accommodate your blood type. The official book outlining the effective methods of the diet was written by Dr. Peter D'Adamo, and has continued to be a bestseller for years. While many attest to the method as an effective means of dieting, new research has indicated that the theory behind the eating plan is not as successful as it claims to be. Here is a general overview regarding the blood type diet, what it entails and what experts are saying about it.
How it works
Dr. D'Adamo persists that the secret to healthy eating and losing weight is through knowing what type of foods cater to your specific blood type. The four major blood groups of A, B, O and AB each have their own distinctive nutritional plan that will work with lectins, or carbohydrate-binding proteins, in the body to maintain not only a healthy nourishment balance, but also prevent various diseases and ailments from affecting ourselves as well. D'Adamo breaks each blood type down into these categories:
- Type A is "the agrarian or cultivator" group, where an emphasis on vegetables and avoiding red meat are encouraged.
- Type B is "the nomad" group, where dairy products are the main source of nutrition to help boost your immune system.
- Type AB is "the enigma" group, and should be focused on an even balance between both the Type A and B diets.
- Type O is "the hunter" group, and consists of a predominantly high protein meal style of diet.
Things to know
The overall theory behind the blood type diet is that you are imitating the type of foods your ancestors ate thousands of years ago. After reviewing various anthropology research studies to determine the types of agriculture prehistoric humans with their respected blood types would have consumed, D'Adamo developed his dietary outline according to his conclusions. The doctor also encourages continuous physical activity along with the eating plan to see any major results, and the specific exercises also pertain to your specific blood type. Some examples include that Type A's should stick to more meditation and stretching activities such as yoga and Tai Chi, while Type O's need to focus on more aerobic based exercises, such as jogging and cycling.
Other key attributes outlined in the diet according to D'Adamo's book include:
- Knowing which spices and condiments on top of foods will help someone of a specific blood type achieve ideal health and weight.
- Which antioxidants, vitamins and minerals should be emphasized as well as avoided.
- The proper medications that function cohesively in your system.
- What types of physical exercise can be alleviate your symptoms of stress, fatigue and soreness.
- Understanding the characteristics of your blood type to avoid experiencing common illnesses and infections.
- Slowing down the aging process by avoiding specific health factors that negatively impact your blood type and cause rapid cell deterioration.
Does it work?
Millions of books sold and countless positive testimonies later, researchers from the University of Toronto have recently put D'Adamo's dieting theory to the test. The doctors assembled a study consisting of 1,455 study participants, equally ranging from the four main blood types and all considered to be healthy, to see how the diet impacted their health and weight. Before beginning the blood type diet, the participants supplied the researchers with detailed information regarding their own personal diets, as well as providing DNA samples that helped distinguish their levels of cardiometabolic risk factors, such as insulin, cholesterol and triglycerides.
After reviewing the results, as well as the proposed diet scores implemented from D'Adamo's book, the researchers confidently stated that no evidence supports this blood type diet theory, and that any indications of positive health attributes had nothing to do with adhering to an individual's blood type. Dr. Ahmed El-Sohemy, a professor from the University of Toronto and lead contributor to the study, was very stern of his team's findings.
"Based on the data of 1,455 study participants, we found no evidence to support the 'blood-type' diet theory," El-Sohemy said in a statement. "The way an individual responds to any one of these diets has absolutely nothing to do with their blood type and has everything to do with their ability to stick to a sensible vegetarian or low-carbohydrate diet. We can now be confident in saying that the blood type diet hypothesis is false."
Whether or not the diet is a complete farce or not, the obvious proponent to anyone trying to lose weight and maintain a healthy lifestyle is simply through eating nutritiously and receiving significant physical activity every week. If the blood type diet is working for you, there is surely nothing wrong with sticking to it, however, in the end, nothing beats old fashioned nutrition and exercise.

Your joints are the pinnacle for your body's ability to move and stay active, and without maintaining their flexibility through nutrition and other factors, your bone health will suffer as a result. If you plan on living an energetic lifestyle as you continue to get older, you will need to keep your joints engaged with various exercises. Distinct habits can help prevent too much pressure and force from being applied, which will cause stiffness and ultimately increased immobility. On top of a well-balanced diet, here are some tips to help you maintain healthy bone joints through aging.
Practice your posture
There is a reason why your parents always told you to sit up straight, and it doesn't necessarily have to do with being well mannered. The way you sit, stand, walk or run can have an enormous impact on your joint health, especially if you continue to practice incorrect posture. If your job requires long periods of sitting, always try to keep your back straight and have both feet on the floor, which will help avoid unnecessary episodes of stress on your joints. Also try to keep your head level and resist cocking your neck at certain angles, while carrying items such as backpacks or satchels should always be supported with both shoulders instead of only one.
Switch up your exercise
If your bones are starting to ache after every time you go out for a run or play a sport, it probably isn't because you are out of shape, but it could be due to the abundance of pressure you are putting on your joints. If soreness and stiffness continue to plague your physical activities, try switching up your exercises for something that has a lower-impact on your joints, such as swimming or cycling. You can essentially receive the same intensity of workout from these forms of activity, and you will save your joints from a lot of pain as well.
As obesity continues to evolve into a growing epidemic, researchers are continuing to try and find new opportunities for rapid weight loss. According to the Centers for Disease Control and Prevention, more than one-third of all Americans are obese, which can lead to serious complications involving cardiovascular health, blood pressure levels and other hazardous health side effects.
Recent studies discuss how bacterial buildup inside our intestines might provide a direct link to diabetes, and fluctuation in our bacterial population could provide a clear connection to being overweight. Intestinal flora, or microorganisms that live within our intestinal lines, was the subject of focus for researchers from Vrije Universiteit Brussel in Belgium. The collaborators tested 169 obese participants and 123 non-obese subjects to determine whether their intestinal flora could spell out weight loss for them in the future. The researchers said that individuals with minimal bacterial species in their intestines are more likely to develop complications from obesity, specifically regarding abrupt weight gain conditions and chronic inflammation. Essentially, obese or healthy-fitted people with low intestinal flora had higher risks for hazardous side effects than those with rich intestinal flora.
The most important aspect to the examination was that weight gain was found to not officially be a primary diagnosis to some the worst elements of poor intestinal flora intake. Gut bacteria is essential for your body to improve its digestive process and boost immune health. The human gut pertains about 10 times more bacteria than all the cells throughout your body combined, protecting your intestines from infection, improving the lining of your immune system as well as regulating metabolism.
Jeroen Raes, a professor at Vrije Universiteit Brussel and lead contributor to the study, acknowledged that you don't have to be overweight to experience all the typically related symptoms of diabetes.
"We were able to distinguish between two groups based on their intestinal flora: people with a large richness of bacterial species in their intestines and people with a few less bacterial species," Raes said in a statement. "A species-rich bacterial flora appeared to function differently compared to the poorer variety. It was surprising to see that obese and non-obese people were found in both groups."
Factors for unhealthy gut flora
As further studies are necessary to help understand intestinal flora's relationship with overweight symptoms, there are several factors that can pay into developing unhealthy gut flora. These lifestyle choices can include:
- Diets high in refined carbohydrates, sugar and processed foods
- Diets low in fermentable fibers
- Dietary toxins like wheat and industrial seed oils
- Chronic stress
- Chronic infections
If you are concerned about maintaining a healthy intestinal flora level, there are still plenty of ways to avoid inflammation of intestinal bacteria. Ingesting plenty of fermentable fibers, such as sweet potatoes or yams, can be beneficial, as well as eliminating your use of table salt and sodium intake with your diet. These are just a few of the ways intestinal bacteria can not only help you avoid obesity, but defend your immune system from unwanted illnesses as well.
While some people enjoy their favorite junk foods when coping with stress, there are plenty of healthier food choices available that naturally reduce anxiety. If you can eat nutritiously, receive all the essential antioxidants and minerals your body needs and ease all your mental tension at the same time, wouldn't you want to take advantage of it? Put down the ice cream and throw out the cookie jar, here are five healthy options that can help you eliminate stress:
Salads, sandwiches or all by themselves, the flavor of an avocado is extremely compatible. They are also known to help alleviate stress thanks to their abundance in potassium, a key mineral that helps blood pressure stay low.
Don't take our word for it, trust researchers from the University of Basel in Sweden where doctors discovered all of the brain boosting and mental calming qualities drinking green tea can provide. The colleagues supplied green tea supplements to a number of volunteers, finding that it was able to improve overall cognitive performance. This meant that the brain's connectivity effectiveness was increased, leading to better memory and decreasing the likelihood of psychological trauma.
A huge contributor of protein and omega-3 fatty acids for our bodies, salmon is a great way to relieve your stress. Researchers from Ohio State University have attributed eating 2.5 grams of omega-3, which would be the equivalent of having a 12-ounce salmon fillet, can reduce your stress by upwards of 20 percent. Salmon is an ideal entree option that will pack you with protein while calming down your nerves.
Pretzels tend to get a bad reputation as an unhealthy snack due an abundance of salt, but eating pretzels made from whole-wheat bread has some truly nutritional qualities. Not only can whole-wheat pretzels stimulate some energy in the body, but its carbohydrates work to release a chemical in your brain known as serotonin, which is known to help put you in a good mood and increase motivation.
For a perfect snack that will help reduce your hunger as well as your anxiety, almonds are great. The generous portions of zinc in almonds help to boost your immune system, allowing you to feel terrific all day.
Water conservation is an often unacknowledged environmental issue that can impact not just your life but the lives of many other people and animals. It's a matter that truly affects our country, and with the average American using upwards to 100 gallons of water everyday, at least 36 states have projected water shortages within the past year. Everything from protecting ecosystems, conserving energy and saving money can be linked to water conservation, and the best place to start exhibiting concern for preserving the world around you can begin in your own home. The kitchen is a primary location for water waste, and cooking is its main partner in crime. Here are just a few tips to utilize water to the fullest while preparing your next meal at home:
From pasta to poultry to potatoes, practically every food can be cooked through steaming, which is also an excellent way to conserve water in the kitchen. Steaming food preserves a generous amount of water compared to boiling, typically using more than 50 percent less water while still serving as a healthy method of preparing a meal. Steaming is also able to preserve more nutrients than boiling, especially with vegetables because the food is not completely submerged in heated water which tends to evaporate the majority of the nutritional content.
Double it up
Sometimes preparing a full course dinner for the family requires an abundance of pots and pans. Instead of having every food item dedicated to a specific kitchen appliance, cook two foods with one pot instead. If you are boiling pasta, wait until there are only a few minutes left on the timer and add the veggies you are using, which generally only take two to three minutes to cook anyway. You will be amazed at how using this food preparation strategy can gradually reduce the amount of water you use to cook over time.
Reduce your measurements
Typically the directions for cooking food tend to lean on the generous side of measurements when it comes to water portions. The truth is that you don't necessarily always need the amount of water called for on the packaging instructions, and skipping out on a few ounces or cups of water with every entree starts to add up in the long run.
Doing the dishes
People are prone to go overboard when it comes to how much water they use to clean their dishes. First off, continuing to run water while soaping down and scrubbing off food debris is a classic wasting offense. Simply plugging up your sink, making a little bath for your dishes and only use the amount of water you have provided for yourself will easily save gallons every time you have to clean. Also, what is the point of sending a plate or bowl through the dishwasher if you have already rinsed and cleaned it out in the sink? Try to stick to one or the other and odds are you will be doing yourself a favor when it comes to your water bill.
Juicing is essentially an attempt to cut out the middleman when it comes to extracting the nutrients of fruits and vegetables. While some argue in favor of juicing because it helps your body digest nutrients easier than it would processing entire foods, others warn that the processes causes you to miss out on primary health benefits such as dietary fiber intake. While the debate rages on, here are a few reasons why juicing is a great resource for health benefits, and a few ways that you can make up for any lost nutrients and still relish the savory contents of a refreshing glass of juice:
Help your digestive system
The biggest advantage of juicing is how it makes the digestive process much simpler for your body. When extracting all of the juice from fruits and vegetables, you are giving your body a rest from having to expend energy breaking down all the solid contents. Your stomach needs to use a number of different digestive enzymes when you consume foods with different vitamins and minerals, which can result in bloating and indigestion. Juicing typically means you are only consuming a few specific foods at a time, which can relieve stomach discomfort and also speed up the digestive process.
Boost your immune system
Juicing is a great way to treat common illnesses, especially if you are prone to deal with allergy symptoms on a daily basis. Chopping up some carrots and apples and pooling their health resources together will provide you with plenty of vitamin A to flush out unwanted toxins in the body as well as generous amounts of vitamin C to fight against cold and flu components.
Adding to the list of benefits, juicing can be a great way to help cut some calories from your diet and lose weight, but it is important to keep track of everything you are putting into the juicer. A common misconception with juicing is that simply dumping fruit and vegetables into the machine will eliminate the calories the foods possessed originally. As always, moderation is key. Be sure not to overdo your juicing, because three or more beverages can easily start to pack on the pounds due to calorie and sugar levels.
Keep in mind that there is no hard scientific evidence to prove that juicing is healthier than consuming whole fruits and vegetables. The attraction of juicing is due to the body's ability to absorb nutrients more quickly in liquid form. Plus, it's a great way to get creative in the kitchen and come up with new concoctions that taste great and have your body feeling even better. Remember that while juicing is a fast and easy source for nutrients, it is always advised to continue consuming whole fruits and vegetables as well.
While regular exercise, stress reduction and tranquility in the workplace are three giant factors in regards to healthy aging, nutrition is arguably the most important. What you put into your body impacts both how you feel and how you look. Researchers have stated that eating processed foods or drinking beverages high in sugar will accelerate the signs of aging, from interior and exterior standpoints.
Here are a few commonly consumed foods and beverages that you probably didn't know were bursting with essential vitamins and healthy antioxidants that may help keep you thriving with every turn of the calendar.
The berry family is as nourishing as it is delicious, and the nutritional value is seemingly infinite. Blueberries, raspberries or cranberries, it is hard to go wrong when every berry choice is loaded with a wide abundance of vitamins, flavonoids, polyphenols, probiotics and tons of other key antioxidants. Flavonoids are known to stimulate brain power and offset chances of cognitive decline and blackberries contain the highest level of the berries, while polyphenols abundant in strawberries are renown for their cardiovascular support and anti-inflammatory properties. Many researchers have examined the healthy aging impacts provided thorough consuming berries, including their ability to promote beneficial maturation.
From losing weight to boosting brain function, the effects green tea has on aging are as valuable as they are copious. It was recently reported that researchers from the University of Basel have examined how adding more green tea to your diet can improve your memory, boost overall cognitive performance and effectively connect neurons from the frontal and parietal brain regions. It's also essential for your skin, possessing several antioxidants that help dermis and epidermis cells grow properly leaving you with an illuminating glow the older you become. Green tea is also high in the chemical epigallocatechin gallate, or EGCG, which helps stimulate metabolism and provide immediate relief for sickness.
An ideal entree for anyone looking to cheat the symptoms of aging, a couple servings of fish per week can go a long way for your health. From canned tuna to smoked salmon, fish are loaded with omega-3 fatty acids that can do everything from lower cholesterol to reduce cognitive decline. The American Heart Association recommends that everyone consume fish at least twice a week. In fact, symptoms from a lack of omega-3 fatty acids in your diet can include dry skin, poor memory and mood swings.
An underrated snack that needs the nutritional recognition it deserves, nuts are a healthy treat for aging symptoms and an ideal way to satisfy hunger between meals. First off, adding nuts to your diet will help reduce the levels of low-density lipoprotein, or "bad" cholesterol in your body, while also working to improve the lining of your arteries, accelerating blood circulation. The number of anti-inflammatory properties found in every handful of almonds, hazelnuts or peanuts may help to decrease the likelihood of acne or skin irritation, as well as boosting your vitamin E intake.
Youthful looks are hard to come by the older you get, which is why a steady intake of tomatoes will have your skin looking younger than ever before. Tomatoes are loaded with lycopene, an antioxidant compound that does wonders for your skin, including protection from UV damage as well as decreasing wrinkles. You can add tomatoes to practically any meal, so there is never an inopportune moment to spark a little vigor into your appearance.
Summer is just around the corner, which means that it is time to start shaping up and trimming down to look your best! The No. 1 way to stay cut and feel great in the heat is by eating right and avoiding unhealthy temptations. While scarfing a ballpark frank, chili cheese fries and a sugary snow cone sound like solid summer snacks at the time, indulging in these unhealthy vices will start to pack on the pounds. So ditch the greasy fried foods, ignore the ice cream truck siren and feel good about your dietary decisions with this nutritional list of five quality treats all under 50 calories to keep you lean and on the go this summer!
Of course there is nothing like firing up the grill and relishing an old fashioned outdoor summer cookout, but eating too many meat kebabs are a quick way to expand that belly. Instead, fix up some fruit skewers as a nutritional snack substitute that is as tasty as it is healthy. Cut up some strawberries, melon and grapes that will provide an eclectic blend of antioxidants that won't spoil your appetite and keep you active. Applying a few slices of each fruit to a kebab stick will come out to well under 50 calories, while providing the perfect amount of energy to avoid that mid-day crash.
While carrots and broccoli get all the attention for their nutritional qualities, cauliflower is an often forgotten bite-size snack that boasts as many vitamins and minerals as any of the other usual vegetables. Just one floret of cauliflower possesses three calories, meaning a couple handfuls worth will leave you feeling great for way below 50 calories. Plus, they are packed with boron, a mineral that can help build muscle and enhance testosterone levels, making it an ideal pre-workout treat. You can also steam cauliflower to preserve its vitamin content while making it more tender and tastier.
The plentiful health benefits of avocados have been taken advantage of since the days of the ancient Aztec civilizations, and the fruit continues to provide a healthier snack alternative. One ounce of avocado amounts to around 45 calories, and possesses significant quantities of anti-inflammatory nutrients, such as phytosterols, omega-3 fatty acids and carotenoid antioxidants that boost your immune system. Add in the abundance of iron, magnesium and potassium and you have the perfect snack option that is bursting with taste and nutrition.
This summer, ditch the buffalo wings and head straight for the good stuff. Celery is often served as a side dish accompaniment to fattening appetizers and entrees, but eating them solo will satisfy your hunger without costing you calories. Each stick of celery contains only six calories, while its immense presence of phthalides and coumarin work to lower blood pressure and ease muscle tension. If a plain stalk is a tad too dull for your snack preferences, try dipping them in a bowl of nonfat peanut butter or hummus to help add some flavor.
Filled with a vast variety of essential vitamins and minerals, asparagus is a great snack that can stimulate your mind and your metabolism. Asparagus is thriving with folate, an anti-aging antioxidant that helps fight symptoms of cognitive decline in the brain, leaving your body and your mind healthier. One serving of asparagus, while containing only three calories, has zero milligrams of sodium and cholesterol as well as zero grams of fat, helping your stomach feel full without looking it.
It is easy to see how getting the family together for dinner can be put on the back burner. Whether it is soccer practice, guitar lessons or staying late at the office, a sit-down meal with the entire family can be hard to make happen. While work and hobbies are always essential components to the day, finding the time to get everyone together for a home-cooked dinner is a lost art that many families are missing out on. So, if your family enjoys supper scattered around the house or in front of the television, it may be worth making family dinner time a priority.
Bring everyone together
One of the obvious motivations for gathering the family around the dinner table is simply to cherish an opportune moment in the day when everyone is together. Recent surveys have estimated that only 40 percent of families in the U.S eat dinner together around three or fewer times per week, while 10 percent of families never eat supper together. While it's somewhat unreasonable to expect to mesh everyone's schedules together seven nights a week, planning family dinners in advance will help to improve the overall sense of unity, not to mention get everyone caught up with each other's lives. In an era where quickness and technology are held to the highest regard, sometimes sitting down, putting away the phones and sharing a healthy meal and discussion is the greatest virtue a family can have.
Emphasis on nutrition
There's no doubt that constantly being on the go and shuttling the kids from one activity to another may lead to the occasional fast food pit stop. These drive-thru occasions, no matter how infrequent, can add up and truly take a toll on you or your children's health. It is estimated that around 68 percent of American adults today are considered obese, and nearly 20 percent of children ages 6 through 11 are deemed overweight as well. Fast food intake is higher than ever, and is widely considered a major suspect in this national obesity epidemic. When you cook a meal at home, you are the chef and master nutritionist. Toss together a salad with fresh sliced fruit so that your family can reap the rewards of healthy antioxidants and nutrients. The dinner table is also an opportune time and place to enlighten your kids on their nutrition, explaining to them why fruits and vegetables are so essential to their everyday diet.
Balance your budget
Not only can going out to eat be unhealthy, it can also do some damage to your bank account! It has been estimated that upwards to 50 percent of all meals are eaten away from home, and when you really start to think about that, it can add up quick. This is just another reason why sharing a meal at home can benefit your family. The U.S. Department of Agriculture projects that the average cost to feed a family of four is between $146 to $289 per week. When you start to do the math, you will find that spending around $250 per week on groceries for the whole family accounts to $62.50 per person every week, which results in around $250 spent on meals per month for each family member. Now let's say a family of four dines out three times a week. At an average of $10 an entree, the total bill can be anywhere from $40 to $50 per restaurant meal, which comes to about $150 per week spent on eating out, or $600 a month, on top of already purchasing groceries for home. These casual dining routines can take its course financially over time, which is why sticking to a home cooked meal is just another advantage for the entire family.
Planning the perfect dinner
Establishing specific days during the week is a perfect way to start organizing your family's meals and help everyone stay on the same page. If there is an evening that no one has any scheduled activities, designate it as family pasta night and create your own tradition. Sundays are generally the perfect occasion for such, plus you can spend the day cooking together – why not try your hand a homemade pasta. Make a few rules for the dinner table as well, such as no phones or television so everyone's attention is geared toward enjoying the company and food. Remember, a closer dinner table can be a big step toward a tighter family, so try to squeeze some time in for exclusive dining experiences.
