Many helminths migrate into and through the central nervous system (CNS). Indeed, Angiostrongylus and Toxocara even cause serious human diseases. Is it known what do they feed on when they stay in the CNS? Is it myelin/nervous tissue? I know that the neuropathogenic schistosome Trichobilharzia regenti feeds on myelin/nervous tissue. However, I was not able to find the data for Angiostrongylus or Toxocara (or other neurotropic species). Does anybody have a good reference, please?

Dear statisticians,
For my bachelor's thesis (Health Sciences), I am looking into the relationship between Eating Behaviour and Sensory Processing Sensitivity (a (personality) trait). My research question is therefore: What is the relationship between Eating Behaviour and Sensory Processing Sensitivity?
I have a sample of 150 participants, and I am doing a cross-sectional association survey study.
Eating Behaviour can be measured with the Adult Eating Behaviour Questionnaire, consisting of 35 5-point Likert scale items, that form 8 subscales. Those eight are my dependent variables.
Sensory Processing Sensitivity can be measured via the Highly Sensitive Person Scale, consisting of 27-items 7 point Likert scale, that form three subscales. The independent variables (four) are the total score for Sensory Processing Sensitivity, and it's three subscales.
After excluding participants who completed less than 80 % of both questionnaires, I have 0.26% missing items, only 23 out of 9000 items. As I will need to compute subscores with these items, I do not want these data points to remain missing/zero. As a method of imputation, I was considering mean imputation (so for each missing, imputing the mean of this specific item). I have read that this is not the best recommended method since it does not take into account relationships between variables, but the method is OK when you have very little missing data.
What type of missing imputation would you recommend me to do? The other option I'm considering is multiple imputation.
Please let me know your thoughts, I would be so grateful!
Thanks so much in advance!
Kirsten.

Hello,
Many protein shake powder mixes contain digestive enzymes such as protease, lipase, and cellulase. However, the products do not detail from which organism the proteins are produced or which protein homolog is used. I would imagine that the enzymes are produced in yeast or fungi. I am am curious regarding which organisms are used. Also, is the native form of the protein harvested from these organisms, or are they made to produce a recombinant human version? In the case of cellulase, there is no human homolog, so it must be from another organism. Regardless, should not the host species be listed on the product? Additionally, if the protein is not naturally occurring in humans, is it ever a good idea to consume it in high quantities?
Thank you!

Answer
Digestive enzymes are extracted from animals,plants and microorganisms. Pancreatic enzymes for digestion are extracted in the Middle East from Camel, Cattle and Cheeps.Also yeasts are an important sources in our country as a source of huge enzymes.Lactic acid bacteria are used as lactase source for treatment of lactose-intolerant people.

I am doing research about the influence of the form in which fruit is presented to children (age of 10-12) on the intake of fruit. You can think of the influence of fruit juices on the intake of fruit or the influence of smoothies, fruit animals, pre-sliced etc. 
I'm trying to figure out if children eat more fruit, when fruit, for example, is pre-sliced. So I'm investigating the effect of the form in which fruit is presented on the intake/consumption of fruit.

I am studying food addiction in obese adults and am trying to decide on which questionnaires I should use to assess the different variants of food addiction. 
Relevant answer
Answer
Great question. The only published scale I'm aware of that explicitly taps addictive eating/food addiction is the YFAS, but I concur that the other two scales mentioned (the DEBQ and TFEQ) are also definitely worth considering. The difficulty lies in the fact that there is no clear, consensus definition of what "addictive eating" is, or even "addiction." Here is a link to an early paper we published examining this issue among women with binge-eating disorder.

Food choice is dependent on a wide spectrum of factors, which affect human behavior in different ways. Eating   behavior   is   not   a   constant   phenomenon   but   will   change   with   differing circumstances and experiences of the individual. Men choose fewer high-fiber foods, eat fewer fruits and vegetables and low-fat foods and consume more soft drink. females  have  been  reported  to  be  more  likely than  males  to  mention  more  vegetables  or  less fat or balance as a part of a healthy diet. women  have  been  shown  to  be  more  thoughtful  about  food  and  health  issues  and  they  seem  to  have  more  moral  and  ecological  misgivings  about  eating  certain  foods than  men,  who  are  more  confident  and  demonstrate  a  rather  uncritical  and  traditional.  One  possible  mechanism  for  the  gender-specific patterns  of  healthy  food  choices  might  be related  to  nutritional  knowledge.  Women generally show a tendency to perform healthier food choices and are much more concerned about the importance of food choice and eating behavior to stay in a good physical shape than men.

Relevant answer
Answer
Hi Marina,
Prevention of disordered eating and eating disorders is tricky; many well-meaning but misguided people speak and intervene in various contexts e.g. schools, but when assessed using well-designed research it is very difficult to point to elements that are effective. For example, providing information about problem eating and eating disorders can actually be damaging because the vulnerable pick up "tips" from the "not to do" parts. I attach an article focusing on this "not to do" part. Regarding "what works", the "Body Project" mentioned by Stephen Cheungis one of those that work and I underscore what Solange Cook-Darzens writes about Diane Neumark-Sztainer's work. Effective Programs tend to include media literacy, and activities to increase self esteem and
relationships with peers I attach a review article from 2013 about what works in schools and a relevant recent article worth reading. Good luck, this is a super-important field.

Thanks Thevaki for your response. I am not sure if you have reported your observations in the Immigrants in Canada. In Bangladesh, almost all households whose staple is parboiled rice and cook in a traditional pot on an open flame use an abundant amount of water, then decant or strain (usually when cook large amounts e.g. for a festival) the excess water when rice is done. I am keen to know this is the common practice in southern India.

Effect of stress hormone on potassium level has been published (see: Reid JL et al. 1986. Am. J. Cardiology vol 57, pp 23F-27F).  They showed epinephrine induced  hypokalemia.   Stress hormones will reduce serum potassium levels significantly. In their study they had injected human volunteers with epinephrine and then saw K+ levels drop from 4.06 to 3.22 (average). Following treatment with atenolol (beta 1 blocker) the reduction in K+ was less. However, using beta1 and beta2 blocker was more effective in restoring K+ levels, which indicates stress related effects on K+ were linked to beta2 activity.

I want to assess the association between several variables and the eating behavior in individuals with intellectual disability. Since I have missing data on some variables I want to calculate my regression using FIML in Mplus. In addition I have some clustered (some individuals live in institutions with several individuals from the same institution in my data set) data and some unclustered (some cases life with their families, only one individual out of each family in my dataset) in my data set.
Is it appropriate to use TYPE=complex in this situation? Any good reference?
THANK YOU!
Relevant answer
Answer
I agree, it would be the more conservative approach and honor the nature of your data.  You could also check the ICCs from the unconditional model and if they are low enough, ignore the clustering, although there is debate about that option.  Best of luck, hope it goes well.

Food Addiction is receiving a widespread attention from many researchers nowadays. Recently, this trait has been correlated with obesity development. However, there is still debate either on food addiction itself as a trait or the connection to other problems e.g obesity. Any opinions?
Relevant answer
Answer
It depends on how you define addiction. If you mean only those things that cause biochemical withdrawal symptoms when they are removed (a narrow but popular definition), then most food products don't fit in that definition. However, if you consider the broader definition of addition - repeatedly doing something even though it may cause harm, then food addition is a valid concept.
Some people have narrowly defined food addition as "binge eating", but that is quite a narrow definition. Assuming you agree with the definition of repeatedly doing something although it may cause harm, then "Food addition" could range from binge eating to constant eating to overeating certain foods to craving and eating only the same narrow set of foods over and over. Each of those can be destructive behaviors but result in different consequences from bulimia to obesity to chronic malnutrition.
The following are some scenarios of "food addition" - people may agree with some and disagree with others.
A obese person who overeats at every meal.
A vegetarian who only eats salads.
A "cookie monster" who just can't stop eating cookies until the whole bag or batch is gone.
A pregnant woman with pica.
A binge eater who then throws up after eating.
I can think of many other scenarios, but what is key here are 2 things we have to remember.
1) These are all disorders that can be dealt with through various means including education or intervention with therapy, drugs, surgery.
2) Each of them represents a unique individual with a unique set of physiological and psychological differences that must be considered in order for the so-called "addiction" to be modified or stopped.
We also have to be careful that we don't label things we don't agree with as "addiction". For example, I frequently hear people talk about how bad a "diet soda addiction" is. This is an example of "I don't LIKE what you are doing so I will give it a negative label". Drinking diet soda is not an addiction, most science shows no harm from drinking low calorie soft drinks. Many people believe overindulgence in diet soft drinks may be harmful, but generally there is no evidence that shows they are in and of themselves harmful. Thus, drinking diet soft drinks does not meet the definition of an addiction.
