How ultra-processed foods modify and command our food preferences?
It responds to the growing interest in ultra-processed foods among policy makers, academic researchers, health professionals, journalists and consumers concerned to devise policies, investigate dietary patterns, advise people, prepare media coverage, and when buying food and checking labels in shops or at home. Ultra-processed foods are defined within the NOVA classification system, which groups foods according to the extent and purpose of industrial processing.
Processes enabling the manufacture of ultra-processed foods include the fractioning of whole foods into substances, chemical modifications of these substances, assembly of unmodified and modified food substances, frequent use of cosmetic additives and sophisticated packaging. Processes and ingredients used to manufacture ultra-processed foods are designed to create highly profitable (low-cost ingredients, long shelf-life, emphatic branding), convenient (ready-to-consume), hyper-palatable products liable to displace all other NOVA food groups, notably unprocessed or minimally processed foods.
A practical way to identify an ultra-processed product is to check to see if its list of ingredients contains at least one item characteristic of the NOVA ultra-processed food group, which is to say, either food substances never or rarely used in kitchens (such as high-fructose corn syrup, hydrogenated or interesterified oils, and hydrolysed proteins), or classes of additives designed to make the final product palatable or more appealing (such as flavours, flavour enhancers, colours, emulsifiers, emulsifying salts, sweeteners, thickeners, and anti-foaming, bulking, carbonating, foaming, gelling and glazing agents).
What do you think about that?
Relevant answer
Answer
More ultra-processed foods in the diet associates with higher risks of obesity, heart disease and stroke, type-2 diabetes, cancer, frailty, depression and death. These harms can be caused by the foods' poor nutritional profile, as many are high in added sugars, salt and trans-fats. https://theconversation.com/the-rise-of-ultra-processed-foods-and-why-theyre-really-bad-for-our-health-140537

Ecopedagogy is not just the knowledge, it is also a value and behavior - you live it. Habits formed at earlier stage of our lives. So, it is imperative that we introduce ecology as early in someone's life as possible. How early can you do this? Further more, if you introduced 'food garden' it has multiple benefits: it integrates knowledge from many domains, it let's you experience nature as a system as well as helping realize many pedagogical objectives such as promoting attention, creativity, patience and perhaps even multilateral thinking. It also fosters global citizenship. Knowledge in growing things is also a 'preparedness' to catastrophes to minimize their impact. In that sense, its an existential skill for survival. Agricultural literacy is shrinking every day. You can do this much better when they are small as they are also in close proximity to the soil. If they are exposed to diverse crops involved in growing, they are most likely to have diverse diet than those who are not - studies and experience backs up. Then what's the early ecopedagogy is like? Most importantly are there any negative side affects of it, if at all?

Question

If you read the labels on food, you'll see the words "natural flavoring" or "artificial flavoring". The initial impression may be that the first must be good, while the second must be bad but if we look at what natural & artificial really mean in practice, most natural & artificial flavors are exactly the same chemical compounds, differing only by their source and both natural & artificial chemicals are or will be purified in a lab.
Is natural really better or safer or more tasty than artificial?
In some cases, natural flavoring may be more dangerous than artificial flavoring (e.g., natural flavor extracted from almonds can contain toxic cyanide but the artificial flavor has the taste but does not have cyanide).
Few years ago, my students prepared natural & artificial strawberry jams in a practical course. The taste of the artificial was judged to be better unanimously by the technician, my students & me.
Few years ago, a colleague's students made real strawberry ice cream & artificially- flavored strawberry ice cream. I tasted both & the second was more delicious, for me.
These two observations puzzled me. I know something about flavoring but I am not a full-fledged expert so I am asking to learn: Are natural flavorings really better & safer than the artificial counterparts? Is the public health at risk upon consuming foods & drinks with artificial flavors?
Relevant answer
Answer
The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating, or enzymolysis, which contains the flavoring constituents derived from a spice, etc. Artificial flavors, on the other hand, are made from anything else that doesn't fall under the "natural" umbrella. Interestingly, both types of flavors are made in the lab by scientists called "flavorists," who blend various chemicals together. The flavorist creating an artificial flavoring must use the same chemicals in his formulation as would be used to make a natural flavoring, however. Otherwise, the flavoring will not have the desired flavor. Although "natural" sure sounds better than "artificial," ingredients that come from nature aren't always safer than those that are artificially made. There are many deadly toxins that are produced in nature. In addition, artificial flavorings are simpler in composition and potentially safer because only safety-tested components are utilized. Besides health effects, natural flavors also may have more negative environmental impacts than artificial flavors. An example of massoia lactone, which is used for a creamy, coconut, spicy flavor. Harvesting it from the massoia tree in Malaysia kills the tree because harvesters have to remove the bark. In other cases collecting natural flavors involves clear-cutting and carbon emissions, which doesn't happen when flavors are created in the lab.

WHO recommends a fat intake of no less than 15% of the daily caloric requirements (https://www.who.int/dietphysicalactivity/publications/trs916/en/).
However, imagine a catastrophic situation in which a population somehow lost access to fat-rich foods for several years, while still having access to a good supply of carbohydrates, protein and micronutrients. Is there a point at which nutritional problems would arise if the consumption of fat was near zero? Would people survive if this was the case? what if the consumption was 5% or 10% of the total caloric intake?
Could the body survive via its own capacity to synthesize fats from carbohydrates?
-Please assume that essential fatty acid consumption (linoleic and alpha linoleic) is covered in this scenario-
Relevant answer
Answer
Current Dietary Fat Intake Recommendations for Adults by WHO (Fats and fatty acids in human nutrition Report of an expert consultation. FAO Food Nutr Pap. 2010;91) -
Total: 20-35%, Saturated: <10%, Trans: <1%, n-6 PUFA: 2.5-9%, n-3 PUFA: 0.5-2%.
Lichtenstein & Van Horn (1998) defined "a very low fat diet is defined as one in which ≤15% of total calories are derived from fat (33 g for a 2000-calorie diet, 50 g for a 3000-calorie diet) with fat calories distributed approximately equally among saturated, monounsaturated, and polyunsaturated fatty acids. Approximately 15% of total daily calories consumed should be derived from protein and ≥70% from carbohydrates."
In contrast, at this time, no health benefits and possible harmful effects can be predicted from adherence to very low fat diets in certain subgroups. In addition to young children, the elderly, pregnant women, and persons with eating disorders should not attempt a very low fat diet. Persons with insulin-dependent diabetes mellitus, elevated TG levels, and carbohydrate malabsorption illnesses should also avoid such a diet.

Árni Mathiesen, Assistant Director-General, FAO Fisheries and Aquaculture made that suggestion at the World Aquaculture Society meeting in France last month.
“When we look to the future we must recognise that there are some constraints that both aquaculture and agriculture have to face up to,” he reflected.
“Due to the deteriorating state of soils, biodiversity loss, climate change etc, the sunlight driven primary production on land might be limited in the future. Therefore aquaculture cannot rely on land-based external inputs as it has done so far and will still do in the short term future.”
As a result, Mathiesen pointed out, it is now crucial to look to the oceans.
As he explained: “Since both the overall and per area primary production of the oceans is far smaller than on land the overall contribution to food and nutrition is much lower, we must look to the ocean’s vast expanse and the fantastic turnover of plankton – both bacteria as well as phyto- and zoo-plankton – to seek opportunites to utilise sun-driven primary production in the oceans.
“Doing this we must look to reposition marine aquaculture in the food pyramid and create an all-inclusive marine aquaculture, sun-driven, primary production food system for the long term future.”

At present, the hegemonic consideration of food in the dominant industrial food system is that food is just a commodity, and thus it is best governed by market mechanisms. As a commodity, the tradeable features prevail and obscure the non-economic considerations of food as (a) an essential resource for humans, (b) produced by nature, (c) considered largely as a human right, (d) undoubtedly being a cultural determinant at individual and societal level, and (e) being governed and subsidized throughout history and at present in most countries as a sort of public good with a public interest. The consideration of food as a commodity is a social construct that has been built by a combination of corporate interest and academic support from the neoclassical economists after WWII. This consideration privileges specific policy solutions and locks policy and legal alternatives that do not conform with the commoditized vision of food. In order to tackle the paramount difficulties the global food system will certainly face during the XXI century, the diversity of value-based narratives of food has to be accepted and legitimized, recognizing that food has multiple meanings (most of them non economic) and that can be governed as a commons or public good based on other moral grounds (not purely based on profit maximization and utilitarian mores).
I would appreciate your insights on these valuations of food (as a commodity, commons or public good) and/or examples where non-commoditized narratives of food prevail or substitute the commoditized vision. Thanks in advance.

In his "Essay on the Principle of Population" published in 1798, Thomas Robert Malthus speculated that human populations grow exponentially whereas the food production grows at an arithmetic rate. According to his theory, it is predicted that in the future there will be a time when humans would have no more resources to survive on ...
Is the Malthusian Theory of Population still valid today?
Relevant answer
Answer
When Malthus lived (1766 – 1834) the global population reached its first billion (in 1804). Today we have 7.6 billion. Even when we can find many arguments that this number is far too high for a sustainable situation on our planet there is statistically enough food produced for everybody of these 7.6 billion. Malthus predicted already in 1798 that population will outrun food supply leading to famine, conflicts over resources, etc.
Although since then many famine have happened, not all were the result of insufficient food production, and in all cases it affected poor populations. Most famines of the 20th century had in addition to povery specific situations, such as wars, civil wars, etc. It is very difficult to argue that they were soley the result of crop failures or sharp population growth.

I am nowadays working on questions of logistics related to malnutrition decrease in Emerging countries. I am trying to search to which field those researches can be related and I found that almost all humanitarian logistics works deal with disasters or emergencies, even during the disaster or post-disaster, but I have difficulties to find non-emergency works. Can someone help me to find a terminology to name this logistics field and know if some authors worked on this. I found a few works on social improvement or social welfare logistics, but the field does not seem to be unified and maybe the terminology is different. Thank you in advance

Answer
I do not understand what Edward wants exactly to say ... Yes, I understand that a definition needs to say what a thing is and what it is not but in the case of non-emergency humanitarian logistics? However, thank you very much for all your answers. I found the term "social welfare logistics" (and "social improvement logistics") which are close to what I intended to say: the logistics operations that allow a social improvement of in general low income or fragile populations.

Hi I need to know  what nutritional disbalance could make that aerial parts of pineapples plants growth so much than the radicular parts and with a huge  acumulation of water on the leafs.
Thanks
Relevant answer
Answer
Imbalance between radicular and aerial parts of pineapple could only happen , when proportion of nitrogen to other nutrients like phosphorous and potassium is proportionately higher . But , best course would be to get leaf analysis done  , and interpret  the leaf analysis results on the basis of nutrient ration , instead of individual nutrient concentration . DRIS concept is one such concept , which can address such issues, besides giving an idea about the order in which different nutrients are causing such imabalnces.  Here is a PDF enclosed to spell out the procedure to be adopted for collection of leaf samples as under:  
‘D’-leaves from 10 different plants were collected at 30 days interval from one representative pineapple field . The basal 4 cm portion from each of the collected leaf samples  to be separated,packed in perforated polythene bags, and brought to the laboratory for onward analysis.

Thank you in advance... 
Relevant answer
Answer
Hi Jagan,
I have two ideas which may solve your purpose those are appended below.
1) You can assume individual particle as a spherical in shape, then measure the individual diameter of particles of a representative sample viz., SEM. Hence, the formula for volume calculation of sphere can be applied.
2) You can get the specific surface area in mm2/mm3 using a Laser Particle Size Analyzer whose theory is based on the preliminary assumption that the particle is spherical in shape.

Overeating can be controlled by the food restriction procedures that may prevent the consumption of various xenobiotics that may disrupt astrocyte-neuron interactions in the hypothalamus that are responsible for appetite control.

I don't think that this issue is that simple. In fact most research in weight loss in humans supports the idea that energy deprivation results in a state were there is a loss of appetite control, specifically disturbed responses of appetite related hormones to food intake, alterations in adipose tissue physiology and overall increase in food craving.

As pointed by Greenfield (1999) and Roulston & Cane (2000), pollen is easily digestible: special adaptations are not needed since pollen grains may be simply destroyed mechanically or through osmotic shock. However there exist a belief that pollen is hardly digestible (mostly because of chemical protection by extracellular wall). Lots of invertebrates belonging to various groups are known to supplement their diets with pollen (even predators). So is pollen easily or hardly digestible? Do you know any papers related to this issue?

I have a number of items that I need converting from grams per day to serving per day. Indeed, how much is a serving per day potato as grams per day?
Relevant answer
Answer
Hi Milad,
This would be dependant on what your country (or country where analysis was conducted) classifies as a serving. In the UK, for example, a serving of vegetables is commonly defined as 80g. Therefore if an individual consumed 160g carrots per daily this would equate to 2 servings. Alternatively, you could look at nationally representative nutrition surveys that detail dietary habits of a certain population (average servings sizes etc) and work things out that way.
Hope this information begins to help a little.
Thanks,

There is substantial evidence that the Western diet is deficient in potassium and supplementing would be easy through adding it to cooking salt which is used daily. It would also lower the sodium intake (since KCl would replace NaCl). The same has already been done with iodine as a global public health action.
Hypertension is an enormous health problem on its own, but also an important risk factor for inducing numerous other long term lethal or debilitiating pathologies, mostly cardiovascular ones. This could be a cheap and effective method to lower the incidence - one which doesn't bear any signficant risks since potassium is tightly regulated in homeostatic terms and the risk of potassium overdose is the same as causing damage with a large acute intake of cooking salt.
Has there been any iniciatives regarding this topic and has it been brought up in scientific, medical or even economic circles? I've never heard of such an idea for a public health intervention. Please comment and share your ideas, especially if you're involved directly or indirectly in medical field. Am I wrong or right to propose such a measure? 
Interesting articles which show the importance of potassium are linked below.
Relevant answer
Answer
Vegetables and fruits are great sources for both minerals and vitamins, and they also contain many other compounds which are very healthy for humans.  There is evidence that even having higher levels of fiber in the diet improves the intestinal microbiota which reduces many disorders, including hypertension.  In general, if all of us ate a well balanced plant based whole food diet we would have a greatly lowered rate of chronic diseases.

India has got its freedom in the year 1947 and we have already passed 68 year. Children are country's future human resources. Their health & nutrition should be in good condition. But recent survey revealed that the state-wide (West Bengal) prevalence of malnutrition was 26.1% & 19.6% in primary & upper-primary students respectively. Another 28.6% & 26.1% of the studied population were `At High Risk’ of developing under-nutrition (3rd to <10th percentile weight & height in respect to age & sex of Indian Academy of Paediatric standard) among primary & upper-primary students. State-wide Ideal Nutritional status was 17% & 23.5% among primary & upper-primary students. Prevalence of anaemia was 29% & 19% among primary & upper-primary students. Other important observations indicated that malnutrition was higher in rural students than their urban counterpart and more in boys than girls. But prevalence of anaemia was higher among girls than boys. Problem of exclusive stunting was 6.9% & 5.7% and that of exclusive under-weight was 6.4% & 4.6% among primary and upper-primary students respectively. Both under-weight and stunting was present in the tune of 12.8% & 9.3% in primary & upper-primary students respectively.
My question is how to improve this situation further as all studied subjects have been receiving receiving school meal programme (freshly prepared cooked meal that is served hot during lunch time)? Does nutrition surveillance at school level will improve the scenario apart from strengthening school meal services including its health components?

I am attempting to analyze the within and between factors as well as compare the means of each group of the following example using a Two-way ANOVA.
Example:
2 independent variables (lean or obese rat  and  low or high fat diet)
1 Dependent variable (% fat in tissue)
# of animals, n=8 per group (32 total rodents in study)
From each rat: 
  • 1 liver tissue slice was examined
  • 12 pictures were taken from each liver (to estimate the % fat)
  • So: 12 pictures x 8 rats per group x 4 groups in the end
Originally I was taking the mean of the 12 pictures (calc in excel) and entering the means into Prism or SPSS using a Two Way ANOVA. So each over-arching group would have 8 means (values in % of fat in the liver). 
Then I thought it may be important to evaluate the differences of the % of fat within the group to see if there was variation in sampling. Pictures were taken and fat was estimated as a percentage.
For example: in the lean rat on low fat diet group
  • There are 8 rats and each rat has 12 pictures to estimate the % fat
  • within this group evaluate the differences between each estimation of the % fat
  • then compare the results to the the three other over-arching groups
Does anyone have suggestions on this approach or recommendations on what test to perform in this instance?
Thank you 
Relevant answer
Answer
I Tom.
I believe you dataset could fit an "ordinary" 2-way ANOVA, as you did first. Actually, the within group variability should be statistically assessed between the 8 rats (not within the 12 pics/rat). The 12 pics per rat are just replicates of the same animal, while the population is represented by the different rats.
Based on this, I am convinced that the "average" of the 12 pics is the value for each rat to include in the stat software. Nevertheless, if you realize that some of the 12 pics you took for each rat is somehow "outlier", you may think of eliminating it (if, for instance, the problem is due to some technical mistake when you made the pic).
I am not really convinced of combining differently the 4 groups and to use tham in different one-way ANOVAs. indeed, your dataset is precious also because the factorial arrangement and statistical evaluation offer you the possibilities of:
1) Comparing 16 vs 16 subjects for the main effects of obesity and fat in the diet
2) Getting additional important information from the possible Interaction between the main effect. You could only get this if you use a 2-way ANOVA
Then, a Tukey's adjustment for multiple comparisons will complete the job in the case the interaction will be significant.

Natural sugar and added sugar seems inseparable in processed food. However, science today highlights the need to avoid added sugar consumption in meal. Food labelling is lacking to quantify the amount of added sugar in the food products except based on the sequence of the ingredient list. Yet, this is in-prefect to protect consumer to over-consume the added sugar in our daily meals.

Answer
Dear Researchers
The refractive index (also called Brix) given by the Refractometer is a measure of all solids present in solution including natural and added sugars and some non sugar substances. That is why a value still appear in cookies with no added sugar as Dr. Aishah found.
HPLC can be helpful if the added sugars are synthetic sweeteners.
But if the table sugar (sucrose) is added to a product containing the same, it will be difficult to detect since both will have same peaks. In this case, a control made of same product processed in same conditions without adding sugar is needed in view to compare different peak areas. Unfortunately this is possible only in laboratory scale because in large scale control of industrial products such control are not available.

I tried to find so many paper in order to answer about cholesterol on risk health. People know cholesterol cause many disease, but the most of paper about liposome preparation use cholesterol to increase liposome stability. Everyday we get lots of cholesterol which is bad lipid from foods then we have to get it from liposome. We want to avoid or reduce cholesterol, while we add it into liposome. In my opinion, it's very a high contrast.  As of consumer, from that information, I need to know about necessary and risk of cholesterol, from either foods or liposome, on human health?

We have a fact that the oxidised LDL-Cholesterol is involved in atherosclerosis.  Is that mean to prevent people from taking cholesterol in their diets? No this is will not happened for 2 reasons 1) you can not eliminate cholesterol to zero level from a healthy diet because cholesterol is associated with animal source that mainly give high biological value of protein, copper , bioavailable iron and vitamin B12. 2) cholesterol has a specific role in manufacturing sex hormones and other functions. Remember liver is the main place to manufacturing cholesterol.  So we need cholesterol, old dietary guidelines were warning people from eating eggs because eggs are sources of cholesterol, 100 g egg contain approximately 250-300 mg cholesterol.  However, USDA and other organisations ignored that in the new dietary guidelines because phospholipids in the eggs help to reduce cholesterol level. There is also a new trend that saturated fats were not responsible for increasing cholesterol and the studies linked between high consumption of saturated fats related to increase cholesterol levels were poor studies!  Finally three words can give us a clear route for healthy nutrition:  Moderation, Variety and Balance.

Actually, we are doing In vitro availability of calcium for food here. After some reading found out that, the ingredients of food may influence the absorption of calcium via the semi-permeable membrane. From the understanding, the composition such as casein or phytate do influence the absorption of the calcium, which could probably be related to the binder as mentioned by both of you.The comments enhance the understanding.
