Energy Density and Nutrient Density are two important terms to understand when making food choices. Foods that are Energy Dense contain higher number of calories per serving, while foods that are Nutrient Dense contain higher levels of vitamins, minerals, and other important nutrients with little or no added sugars or fats that raise calories. Think of the difference between potato chips and plain baked potato, or sweetened yogurt and plain yogurt, or creamed spinach and steamed spinach. Adding fat or sugar to foods increases the calorie content, making these foods more energy dense. Choosing Nutrient - Dense Foods more often allows us to consume higher number of essential vitamins and minerals that promote good health, while avoiding consuming too many calories that can lead to overweight or obesity. At daily calorie levels between 1 200 and 1 800, < 10% of the total calorie budget remains after consuming foods that contain all the nutrients we need. By time you eat all the fruit, vegetables, whole grains, and protein foods your body needs for optimum health, there are only 120 - 180 calories left over each day for sugars and fat for people who need 1 200 to 18 000 calories per day. If we choose Energy - Dense versions of these foods, for example, eating sweetened canned fruit, vegetables with extra butter or cheese, processed grains like French fries instead of potatoes, and higher - fat protein foods like sausage or deli meats, then we will consume far more calories than we need. 120 - 180 calories does go very far: 12 ounces of regular soda contains 150 calories all from sugar, while 1 ounce of potato chips contains 155 calories primarily from fat. Most Nutrient - Dense Foods, on the other hand, are low in calories. A recent meta - analysis of 13 experimental and observational studies that looked at over 3600 people aged 18 to 66 years showed a significant association between consuming low - Energy - Density foods and body weight. In other words, people who eat more nutrient - dense foods that are naturally low in calories weigh less than people who consume more foods that are higher in calories and lower in nutrients. Another benefit of Nutrient - Dense Foods is that they are often high in water and fiber, which increases their volume without increasing calories. For example, compare the volume of 100 calories of raw apple to 100 calories of apple juice. About 2 cups of sliced raw apples contain 100 calories, while 1 cup of unsweetened apple juice contains 113 calories. Youll feel more satisfied by eating apples instead of drinking juice because the total volume of food that we consume is the primary reason for satiety. We can eat larger volume of low - energy, nutrient - dense foods and lose weight while feeling satisfied. Tips to reduce Energy Density and increase the Nutrient Density of your food choices: start lunch or dinner meals with fresh vegetable salad to help you start to feel more full. Use the least amount of salad dressing as possible.

Definition and usage

There are a vast number of essential nutrients, and they are all vital for human health. Non - adequate supply of any nutrient causes medical problems. Some nutrients are, however, more abundant than others. Some nutrients are found in almost all kinds of foods, while others are hard to find. Instead of merely adding up all nutrients, their abundance is taken into account when determining nutrient density. One example of this is choline. Choline is a vitamin - like nutrient that has various roles in the body, and that is crucial for cardiovascular health. There are only a few food sources that contain decent amounts of choline. This includes liver and eggs. 100 g beef liver contains more than 400 mg of choline, which accounts for around 80% of recommended daily intake. 100g of eggs contains almost 300 mg of choline. Because eggs and liver contain nutrients that are hard to find in other foods, they are considered as especially nutrient - dense.


Bioavailability

Bioavailability of nutrients and its effect on nutrient density are nearly impossible to determine. For example, 418 kJ of raw spinach has 431 mg Ca, more than 359 mg Ca in 418 kJ of non - fat milk. But while 418 kJ of non - fat milk is a reasonable serving size, 418 kJ of raw spinach is not. Also, some plant foods, like spinach, contain high concentrations of indigestible salts, such as oxalic acid, which is a potent inhibitor of Ca. Thus, mean Ca absorption from spinach is only 5% compared with mean of 27% from milk ingested at similar load. However, oxalate content of spinach varies widely among samples, which would alter interference with absorption in spinach in different samples. The same argument can be made for Fe; non - haem Fe found in spinach is not as bioavailable as haem Fe found in meat. Moreover, overall efficiency of Fe absorption is linked to the Fe status of an individual; if someone is Fe deficient, he / she will absorb more Fe. Absorption of non - haem Fe is also influenced by other foods consume; for example, Vitamin C increases absorption of non - haem Fe, as does concomitant consumption of foods with haem Fe. These physiological variations, both in animal and plant foods and in absorption potential by consumers, make it virtually impossible to include bioavailability of nutrients in foods in any consideration of nutrient density algorithm, although they are extremely important.


What are the most nutrient-dense foods?

This depends on the ultimate use of nutrient profiling and the country involve. If nutrient profiling is to be used for regulatory purposes, appropriate agencies will need to be involve; for example, if terms are to be used for food labels in the USA, Food and Drug Administration should be the agency to establish criteria. Consumer education uses could potentially involve consumer groups in conjunction with regulatory agencies and industry. For advertising to children, Institute of Medicine might set criteria, in collaboration with industry. If nutrient profiling is to be used for other purposes, such as television advertising for children, other agencies might need to be involve. In Europe, consensus of the European Union would be important.

International standards

The Nutrient Profiling Scoring Calculator in Australia and New Zealand is a calculator for determining whether Health Claims can be made for Food by its Reference to Nutrient Profiling Scoring Criterion. It is defined by the FSANZ Board, which operates under the FSANZ Act. The United Kingdom Ofcom Nutrient Profiling model provides a single score for any given food product, based on calculating the number of points for negative nutrients which can be offset by points for positive nutrients. 2007 UK - Commission review of Nutrient Profiling models Commission by UK Food Standards Agency identified over 40 different schemes. The World Health Organization reviews scientific and operational issues relating to human nutrition, specifically when developing world populations are affected

How to Identify Nutrient-Dense Foods

At the grocery store, look for whole foods such as produce, fresh lean meats, whole grains, nuts, seeds, and legumes. These foods may be more expensive than energy - dense package foods, but you buy more nutrition for that price. Most shoppers choose some packaged foods for convenience, but you can still make smart choices with those productsjust by reading labels. You 'll find Nutrition Facts labels on the backs or sides of packages. Look at serving sizes, note the number of calories per serving, and see the amount of fiber, protein, vitamins, calcium, and iron. Package food that has a better combination of lower calories, more nutrients, and less saturated fat, adding sugar, and sodium is the winner. You can expand your food shopping to include farmers markets where you can buy fresh vegetables and fruit. These won't have Nutrition fact labels, but they are naturally nutrient - dense.

What About Snacks?

Now that you understand what nutrient - dense foods are, you can start adding more of them into your eating plan. Sometimes it only takes a small shift to make a more nutrient - dense choice. For example:, switch from white rice to brown rice. Replace sugary drinks with water, unsweetened tea, or coffee. Instead of big dollop of sour cream on your chili or baked potatoes, try plain nonfat Greek yogurt. Switch from processed deli meat to sliced roasted chicken for a hearty sandwich. When adding toppings to pizza, tacos or sandwiches, think one more veggie instead of meat or cheese. Snack on crunchy vegetables or nuts instead of chips. Satisfy your sweet tooth with naturally sweet fruit instead of candy and cookies. Whether youre student studying for tests, professional preparing for big presentation, or mom raising family food choices, you make directly impact energy and focus you have to achieve your goals. By making some simple swaps in your favorite recipes or reimagining favorite dishes, you can boost the nutrient density of your family meals and snacks.

H=N/C

This simple equation defines how your health is related to the nutrient density of your diet. Adequate consumption of micronutrients, vitamins, minerals, and many other phytochemicals without excessive caloric intake, is key to achieving excellent health. To illustrate which foods have the highest nutrient - per - calorie density, Dr. Fuhrman created an aggregate Nutrient Density Index, or ANDI. It lets you quickly see which foods are most health - promoting and nutrient dense. Andi ranks the nutrient value of many common foods on the basis of how many nutrients they deliver to your body for each calorie consume. Unlike food labels which list only a few nutrients, ANDI scores are based on thirty - four important nutritional parameters. Foods are ranked on a scale of 1 - 1000, with the most nutrient - dense cruciferous leafy green vegetables scoring 1000. It is also important to achieve micronutrient diversity, not just high level of few isolated micronutrients. Eating a variety of plant foods is essential to good health. It is important to include a wide assortment of plant foods in your diet to obtain a full range of nutritional requirements. Include onions, seeds, mushrooms, berries, beans and tomatoes as well as greens in your diet. They all contribute to the numerator in the H = N / C equation. For your good health, take minute to evaluate the quality of your current diet and learn which foods you need to consume to improve it. A more comprehensive list of ANDI scores can be found in Dr. Fuhrmans Nutritarian Handbook and ANDI Food Scoring Guide.

How Nutrient Density Works

Nutrient Density refers to how many nutrients you can obtain from food, given the number of calories it contain. Similar to the way energy density focuses on calories per serving, nutrient density is a simple way to forge a link between nutrient content and calorie count. Foods that are nutritionally dense provide most nutrients for the fewest number of calories. That is exactly why picking out foods with high nutrient densities is vital for healthy dietary habits. So why is the nutrient density method so helpful? It tells you just how many valuable nutrients are present in food that you are consuming. These essential nutrients are important for smooth functioning of our immune system, natural detoxification processes and cellular repair mechanisms, which protect us from diseases and bacteria.

Nutrient - dense foods are real and unprocessed as opposed to chemically altered, manmade or filled with synthetic ingredients. Nutrients found in healthy, whole food include micronutrients like essential vitamins, trace minerals and electrolytes like magnesium / calcium / potassium, plus macronutrients, including carbohydrates, proteins and different types of healthy fats. A well - round, largely unprocessed diet is superior to taking supplements and eating a processed diet because real foods have complex chemical structures that are very difficult to replicate. For example, antioxidants and phytochemicals found in many plant foods support the immune system, body detoxification processes and cellular repair. Base on the amount of nutrients in proportion to the amount of calories that these foods have, here are the most nutrient - dense foods available in the US: seaweed liver leafy greens, like kale, collards, spinach, watercress, dandelion greens and arugula Broccoli rabe, broccoli, cauliflower and other cruciferous veggies like cabbage or Brussels sprouts Exotic Berries like acai, goji and camu camu Red, yellow, Green and orange bell peppers Carrots and parsnips Garlic Parsley, cilantro, basil and other herbs Berries asparagus Beets Wild salmon and sardines Bone broth Grass - fed beef Green beans Egg yolks Pumpkin Lentils Artichokes Tomatoes Wild mushrooms Seeds: Pumpkin, sunflower, chia and flax Raw cheese and kefir Sweet potatoes Black beans Wild rice Yogurt Cacao Avocado

What Makes Superfoods so Super

Superfoods are foods mostly plant - base but also some fish and dairy that are thought to be nutritionally dense and thus good for one's health. Blueberries, salmon, kale and acai are just a few examples of foods that have garner superfood label. However, there are no set criteria for determining what IS and what IS not superfood, according to the American Heart Association. Superfoods don't have their own food group, says Despina Hyde, registered dietician with the weight management Program at New York University's Langone Medical Center. As a dietician, I think'superfood IS more of a marketing term for foods that have health benefits. Superfoods contain a variety of nutrients, such as antioxidants, which are thought to ward off cancer. They also have healthy fats, thought to prevent heart disease; fiber, thought to prevent diabetes and digestive problems; and phytochemicals chemicals in plants responsible for deep colors and smells, which can have numerous health benefits. Consuming foods that are packed with nutrients IS certainly a good idea, Hyde told Live Science. But the key to a healthy diet IS to consume a variety of nutritious foods in the right quantities, she add.

A nutrient - dense diet is the best protection against nutrient deficiencies. But what exactly is the most nutrient - dense diet? There are several studies that have attempted to answer this question. In the most comprehensive one, referred to as the Maillot study, researchers looked at seven major food groups and 25 subgroups, characterizing the nutrient density of these foods based on the presence of 23 qualifying nutrients. The table below displays results; each food was given numbered score for reference, with highest numbers corresponding to highest levels of nutrient density. Even without considering bioavailability, all categories of meat and fish, vegetables, fruit, nuts, and dairy were more nutrient dense than whole grains. Meat and fish, veggies, and fruit were more nutrient dense than legumes, which were slightly more nutrient dense than dairy and nuts. What would scale have looked like had researchers separated caloric density from nutrient density? Harvard University chemist Dr. Mat Lalonde uses a formula similar to that used in the Maillot study, but without penalizing foods to have more calories. The results, which he shared at the Ancestral Health Symposium in 2012, are below. On the Lalonde scale, organ meats are again the most nutrient - dense foods by far, followed by: herbs and spices. Nuts and seeds, Cacao seafood, red meat, and wild game were more nutrient dense than raw vegetables; all forms of meat, fish, fruit, and vegetables were more nutrient dense than grains and pseudograins. If bioavailability had been taken into account in both the Maillot study and Lalondes analyses, legumes and grains would have been even lower on scale when compared to organ meats, meats, dairy products, and fruits and vegetables. It is worth noting that both Maillot and Lalonde analyses only include nutrients like vitamins, minerals, protein, fiber, and essential fatty acids, all of which have been proven to be essential. As I touched on earlier, in nutrition context, word essential does just mean important or must - have. It means we ca live without these substances and we must get them from food sources, as our bodies ca manufacture them. Although these nutrients should always be the primary focus, research over the past two decades has shown that other nutrients, while not essential, play a vital role in health. They include: polyphenols, Carotenoids Flavonoids Diallyl sulfides lignans. These nutrients are found primarily in whole fruits and vegetables, so had they been factors in Maillot and Lalonde analyses, fruits and vegetables would have scored higher.
