artificial food color

Posted by on

Artificial food colors (or color additives) are any dye, pigment or substance that imparts color when it is added to food or drink. Without color additives, colas wouldn’t be brown, margarine wouldn’t be yellow and mint ice cream wouldn’t be green. It is estimated that there are thousands of additives in our food supply [10]! Color additives are recognized as an important part of practically all processed foods we eat.

According to studies [1-9], artificial food colors may increase inattentiveness, impulsivity, and hyperactivity among young children. They may also harm children’s brains and cause DNA damage in human liver cells. While many international food companies in Europe have taken color additives out of their products, in the rest of the world the situation hasn’t changed.

Please keep in mind that the facts mentioned in this post refer to artificial food colors and not to many of their natural substitutes. To learn more about artificial food colors and their influence, watch this 5-minute video:

health axiom, move more, eat food, drink water, exercise is medicine,get more sleep,wash your hands,teeth health

Here is an obvious fact: people use their hands a lot! Think about it. You wake up, turn the lights on, wash your face, brush (and therefore hold) your toothbrush and open the door knob when leaving the house. Later you will hold the driving wheel, shake hands, use your computer, cellphone and TV, pet a dog, hold your kid and of course EAT – and all is done with your hands.

Through our hands we may be infected or spread diseases like flu, viruses, stomach bugs, food poisoning and others. Washing hands will not prevent the spreading but for sure will reduce the chances for it. The action is very simple – wash your hands with soap and water or use a hand sanitizer. Do it at least:

– Before making or eating food.
– After you use the toilet.
– After you blow your nose or sneeze.
– After you pet your dog or cat, including feeding and cleaning their waste.
– After taking out the garbage.
– After you take care of someone who’s sick.
– After changing a diaper or help your child use the toilet.
– And if you are sick, wash your hands often and try to avoid touching things other people touch as much as you can.

Keep clean and be healthy! :]

brazil nuts

Posted by on

The benefits of nuts are well-known, and more benefits are revealed constantly. Nuts (e.g. walnuts, almonds, macadamia nuts, brazil nuts and cashews) are a good source of protein, minerals and vitamin E. Nuts are also able to protect against DNA damage, suppress cancer growth and inflammation and reduce the risk of heart disease [3].

A new study revealed some crazy news about the connection between four brazil nuts consumption and cholesterol levels. Watch this 3-minute video to learn how a tiny change in your lifestyle may improve your health significantly:

Did you know that certain foods or food components may provide health and wellness benefits? These foods, also known as “functional foods,” may play a role in improving overall well-being and reducing or minimizing the risk of certain diseases and other health conditions [1]. Functional foods are sometimes defined as “foods with benefits beyond basic nutrition” because they contain healthful components associated with specific health benefits beyond the basic macronutrients (protein, carbohydrates, and fat). Examples include fruits and vegetables, whole grains, and some types of seafood. By knowing which foods can provide specific health benefits, you can make food and beverage choices that allow you to take greater control of your health.

The IFIC Functional Foods Survey has been trending Americans’ attitudes towards health-promoting foods for many years, and the 2013 survey confirmed that people are aware that these foods exist and are interested in learning more. The majority of Americans also believe they are not getting all of the nutrients and food components needed for good health in their diet. As you can see from the image below, there is quite a discrepancy between what nutrients Americans think they are getting in their diet versus what they are actually consuming. Foods that contain healthful components can help fill the nutrient gaps in your diet.

Functional foods
So what foods should you look for to meet nutrient needs and improve overall health? The best advice is to include a variety of foods, such as fruits, vegetables, dairy, grains, etc as recommended by the 2010 Dietary Guidelines for Americans and ChooseMyPlate.gov [2], which would provide many potentially beneficial components. You can find a full chart of all the functional components in food and their associated health benefits on the IFIC website. Stay tuned for more articles on specific components such as probiotics and antioxidants, including why you should eat them, where to find them, and how much to eat.

Every year the CDC (Center for Disease Control and Prevention) presents the latest leading causes of death in the United States. This includes a robust analysis of the causes of death, and their breakdown in different states, genders and populations [1]. The goal of this post is not to focus on this morbid statistics. As always in Nutrino, we like to focus on the impact nutrition has. So today, we will ask ourselves (and the data…) a very important question: which of our top killers can be prevented by smart nutrition?

CDC reports from the last few years show that the top 15 leading causes of death remain mostly fixed in recent years [1]. They are (in this order):

1. Diseases of heart
2. Malignant neoplasms (cancer)
3. Chronic lower respiratory diseases (emphysema)
4. Cerebrovascular diseases (stroke)
5. Accidents (unintentional injuries)
6. Alzheimer’s disease
7. Diabetes mellitus
8. Nephritis, nephrotic syndrome and nephrosis (kidney failure)
9. Influenza and pneumonia
10. Intentional self-harm (suicide)
11. Septicemia (blood infection)
12. Chronic liver disease and cirrhosis
13. Essential hypertension (high blood pressure)
14. Parkinson’s disease
15. Pneumonitis due to solids and liquids (lung disease)

Separating the leading causes of death according to gender reveals nearly the same list but in a different order. Men are more prone to die from unintentional injuries than women (guys – let’s not get reckless…).

Leading causes of death in the U.S.

 

1 out of every 2 Americans die from either heart disease or cancer. Together with strokes, these three diseases kill more people than all the other causes of death combined. It is very easy to think about this as only numbers. But they are not just numbers. Every one of us knows someone who suffered from these terrible diseases. Think about it.

A study from the UCSF proved that about 82% of heart diseases and strokes are preventable and even reversible by smart nutrition [2]. About half of cancer cases are preventable by smart nutrition as well, depending on the type of cancer [3].

Do the math to find out the following mind blowing fact:

Bad nutrition is the #1 cause of death in the United States

Similar statistics by the World Health Organization shows that the same is true for the rest of the western world [4].

But this is not everything. The food that you eat is actually much more powerful than you would imagine. In fact, smart nutrition is capable of preventing 14 out of our 15 top killers (the 14 are bolded above). Moreover, in many cases it is capable of reversing 5 of our 15 top killers (heart attacks, cancer, emphysema, diabetes and hypertension) [4].

This is an important story to tell, as it means that you have great control over your health. This is why I recommend sharing these figures with your friends and family – who knows, you may save lives!

So here is a great idea: let’s start eating healthy! I know it’s hard, as there are many temptations. We are surrounded with junk food all the time. But remember, healthy food is a pleasure. It is the only food that doesn’t only nourish your taste buds but actually nourishes your entire body. Not sure where to start? Just download Nutrino. We are here for you.

As a side note I just have to add that the story of bad nutrition as was told here is actually the reason why we founded Nutrino.

How many times have you said that 24 hours a day are simply not enough? Do you feel like you need more hours to finish everything you need to do?

We all have our daily routines. Many of us actually sleep less to have more time to do the things we wish to do. However, doing so is a slippery slope. The quality of your sleep highly affects your productiveness, and by sleeping less to have more time, we may end up being less productive and to do less than we could have if we had slept better.

Studies show that health is influenced significantly by the quality and duration of our sleep [1]. Sleep deprivation

1. Affects the way your body processes and stores carbs, and alters the levels of the hormones that affect your appetite. This is why insufficient sleep typically means desiring sweets or simple carbs, and consequently weight gain.
2. May result in moodiness, irritability, impatience and inability to concentrate.
3. May diminish your antioxidant levels and weaken your immune system.

On the other hand, sleeping sufficiently

1. Helps the brain to process and commit the information you have learned during the day.
2. Is correlated with reduced risk of cancer, stroke, and heart disease.

So how many hours should you sleep?

A Japanese study [2] on nearly 100,000 people analyzed how their sleeping habits correlate with longevity and heart disease. They discovered that 7 hours of sleep a night maximizes health and longevity in the general population.

Just as everything else in health, this is a general result that is based on statistics and should be taken with a grain of salt. Some of us may need more hours of sleep to feel better, while others may require less.

The TED talk below is a great and short video to learn why we sleep, how to determine how much you should sleep and why sleeping is so essential. Enjoy!

Exercise is medicine. It really is! It can help you control your weight, improve your mood, reduce your chances of getting sick, boost your energy, promote better sleep, improve your sex life and very importantly – it is fun [1,2]! Swimming, running, Pilates, Yoga, Kettlebell, TRX, dancing, biking, kick-boxing, Judo, Karate, jogging, climbing, Zumba, tennis and so many other options are available for you to improve your lifestyle.

The minimum recommended time of weekly exercising is 150 minutes (2.5 hours) of moderate-intensity aerobic activity (like fast walking or cycling) or 75 minutes (1.25 hours) of vigorous-intensity aerobic activity (like running) and 2 days of muscle-strengthening activities. You can also mix it and do moderate and vigorous-intensity aerobic activity with muscle-strengthening activities [3,4].

Try to find what works for you. If it’s to vary your week with different types of exercise or stick to a routine workout plan. Work out in the morning before you go to work or at night before you go to sleep, work out at the park or at the gym, work out with a friend or by yourself.

Just don’t give up! If you didn’t like certain activities it doesn’t mean you don’t like to workout at all. It just means that you haven’t found what works best for you. Remember that there are tens of types of exercises and there must be something you’d enjoy!

Iron anemia is the #1 nutrient deficiency in the world

Posted by on

Iron deficiency is the most widespread nutritional deficiency in the world. The World Health Organization estimates that 2 billion people (over 30% of the world’s population) are anemic, most of which due to iron deficiency [1]. So why is iron so important? What should you do to make sure you consume enough of it?

Iron is an essential mineral (meaning that this mineral is required for the body to function normally and that it must be obtained from a dietary source). It is used in hemoglobin to transport oxygen to the cells. However, among the many essential minerals like calcium, sodium, zinc, iron has a unique place: it is very difficult for the body to regulate its consumption [2]. This means that unlike calcium, for example, which is excreted in the urine, excess iron may remain in the body.

This makes iron a double-edged sword. Don’t absorb enough of it, and you risk anemia, which can lead to a range of problems from fatigue to death. Absorb too much, and you increase your risk of hemochromatosiscolorectal cancer, heart disease, infection, neurodegenerative disorders and inflammatory conditions [3]. Excess iron can have negative effects because iron is a pro-oxidant (the opposite of antioxidant which are great for you). Pro-oxidants may induce oxidative stress and DNA damage (and may explain why meat consumption has been tied to breast cancer risk, as meat is high in iron). Several other conditions that are have been associated with high iron intake include Alzheimer, Parkinson, arthritis, and diabetes, but more research is needed to understand how these diseases are connected to iron.

So where should we get iron from?

There are two forms of iron in food: heme and non-heme.

Heme iron is only found in animal-based foods (about 40% of the iron in meat, poultry and fish is heme). It is typically absorbed better than non-heme iron. However, our digestive system cannot regulate heme iron at all, and it is easy to over-consume it whether we need it or not [4].

Non-heme iron is found in both animal-based and plant-based foods (100% of the iron in plants is non-heme and about 60% of the iron in meat, poultry and fish). Non-heme iron can be regulated by our digestive systems. Thus, if our iron stores are low, our intestines enhance its absorption. If our iron stores are too high, our intestines block non-heme iron absorption to maintain us in the healthy range. Therefore, non-heme iron is typically safer for consumption.

The best sources of non-heme iron are legumes (the best ones are soybeans, lentils, tofu, chickpeas and beans – in this order), dried leafy greens (the best ones are Swiss chard, turnip greens and beet greens), nuts and seeds (the best ones are pumpkin seeds and whole sesame paste. The later is packed with 2.4 milligrams of iron in only one tablespoon!). Contrary to common believe, spinach is not a good source of iron. Spinach is indeed rich in iron, but it also contains iron absorption-inhibiting substances: so Popeye tricked us all this time! Oh yeah, and great news, dark chocolate and cocoa powder are other good sources of non-heme iron.

Popeye's spinach prohibit the absorption of iron

The Nutrino team recommends consuming at least two servings of legumes daily (beans, lentils or peas). There are many other good reasons to eat legumes, as legumes are one of the things most 100-year olds have in common and seem to be highly correlated with longevity. In addition, we recommend at least one handful of nuts and/or seeds and no more than one serving of meat a day to avoid overconsumption of iron.

How can I improve iron absorption?

The most important factor in absorbing iron is vitamin C, so you should complement your meals with vitamin C-rich foods (such as citrus fruit, berries, tropical fruit, peppers, cauliflower and other green leafy vegetables like broccoli, kale, collards, Swiss chard and Brussels sprouts).

In one study, researchers gave patients 500 mg of vitamin C twice a day after meals. They concluded that vitamin C is more effective at increasing iron status than supplements [5]. In another study researchers found a drastic improvement in anemia only by adding 100 mg vitamin C at both lunch and dinner [6].

On the other hand, there are foods that impair iron absorption. These include dairy products and milk, coffee, black and green tea [7]. It is therefore recommended to avoid them with your iron-rich meals.

What about vegetarians and vegans?

Vegetarians and vegans are considered to be a risk group for anemia [8]. If you belong to this group, you should be make sure to consume foods that are high in iron and vitamin C (see above).

Here is a list of good sources of iron for vegans and vegetarians:

Legumes
1 cup lentils = 6.6 mg
1 cup white beans = 4.8 mg
1 cup soy beans = 3.6 mg
1 cup garbanzos = 3.6 mg
100 grams tofu = 1.9 mg
1 cup soy milk = 1.1 mg
Grains
1 cup quinoa = 2.8 mg
1/2 cup oatmeal = 7 mg
1 cup brown rice = 1 mg
Vegetables
1 cup parsley = 3.8 mg
1 tbsp spirulina = 5 mg
Fruit
100 grams dried apricot = 6.3 mg
Nuts & seeds
1 ounce pumpkin seeds = 1.6 mg
1 tbsp sesame paste = 1 mg
Example: 1 cup legume (for example garbanzos) + 1 cup soy milk + 1 cup quinoa + 1 cup parsley + 3 tbsp sesame paste = 17.8 mg

Is it worthwhile taking iron supplements?

Only people with a confirmed diagnosis of iron-deficiency anemia should consider using supplements, and even then it can be risky. A recent study found a significant increase in oxidative stress within the bodies of women on iron supplements [9]. So before going on supplements, talk to your physician about trying to treat it through diet alone, by eating lots of healthy foods rich with iron and vitamin C (see the previous questions).

What is the healthiest sweetener?

Posted by on

Sweeteners are an essential part of practically any cuisine. After all, in all traditions and cultures people enjoy the sweet taste of a good cake or a dessert. Sweeteners are usually simple carbs and don’t provide the body with any essential nutrients. However, if you had to use only one sweetener in the dessert you are making, what should it be? Which is the healthiest sweetener? Is it agave nectar, blackstrap molasses, brown rice syrup, corn syrup, date sugar, dark brown sugar, light brown sugar, maple syrup, honey, raw cane sugar, plain old sugar, or turbinado sugar? There are two sweeteners that have some significant nutrition, while the rest are pretty much a wash.

To know the answer and learn more, watch this 5 minute video:

Water is essential for the human body. The human body is made up of 50-70 percent water, depends on age, gender, weight and health. Water has many important utilities in our body: transfer nutrients (like vitamins and minerals) and oxygen to cells, remove byproducts and toxins that the organ cells reject, part of the biochemical break down of what we eat, regulate body temperature through sweating, help energize muscles, an effective lubricant around joints, moisturize the skin to maintain its texture and appearance and much more [1,2].

Most mature adults lose an average of 2.5-3 liters water per day. Our body barely produces water so we need to supply it with water. The amount we need depends on our body size, metabolism, the weather, the food we eat and our activity levels. The best way to supply the body with water is to drink water (and not sweet beverages that contain stuff you don’t want to put in your body! :)). Fruits and vegetables contain 80-95 percent water [3] and therefore are a good source as well.

 

Tips to help you drink more:

1. Keep a bottle of water with you every where you go. If it’s to your office, to school or when you drive.
2. Have a cup of water with every snack and meal.
3. When you exercise have a bottle of water with you, that way you’ll be able to drink comfortably and be aware if you drink enough.
4. Put a glass of water near your bed before you go to sleep, it will remind you to drink water when you’ll wake up.
