The purposes of this project is to collect and present the information on the nutrition composition of two chocolate bars “Mars” and “Milky Way” those are available on Kazakhstan food market, to estimate and calculate energetic and nutrition value of the main nutrients. While knowing multi-directional impact of chocolate bars on human health, I’m eager to give a little insight to chocolate bars selection. Since major chocolate bars available in Kazakhstan are produced by Mars Inc. (Mars, Snickers, Twix, Bounty, Milky Way etc), similar products were chosen - “Mars” and “Milky Way” as subjects of the research. I’ll try to figure out which one is less harmful to one’s health and more preferred for consumption.
Name: Chocolate bar “Mars”
Composition:filling: glucose syrup, sugar, vegetable fat, whole milk powder, fat-free cocoa powder, malt extract, skimmed milk powder, whey powder, lactose, salt, dried egg-white
chocolate: sugar, cocoa butter, cocoa mass, skimmed milk powder, whole milk powder, lactose,whey powder, dehydrated milk fat, emulsifier (soy lecithin), natural identical flavoring (vanillin)
Also may contain insignificant amount of peanuts
Main properties:featuring nougat, soft caramel and coated in milk chocolate Food category:chocolate bar
Production:according to UltimateChocolateBlog: “the Mars Incorporated patented proprietary process called Cocoapro™ that helps retain the efficacy of the flavanols. Mars scientists developed it to reduce the cocoa bean’s exposure to high temperatures, helping protect the flavanols inside. This process ensures delivery of cocoa extract and powder ingredients that are guaranteed to have consistently high levels of cocoa flavanols” Significance:beneficial effects of chocolate include anticancer, brain stimulator, cough preventive, reduced risk of heart disease, anti-diarrhoea effect, also, chocolate bar filling (nougat) could serve as a supplement of sugar and calcium. On the other hand, excessive consumption may lead to obesity and sugar diabetes. Nutrition ratio:159 kcal, 6.3 % (assuming adult daily consumption is 2500 kcal) Nutrition facts:Sugar - 21.7 g; Fat - 6.4 g; Saturated Fat Acids - 3.7 g; Sodium - 50.2 mg (out of 35 g serving size) Metabolism:various studies suggest chocolate bars boost up human metabolic rate
Name: chocolate bar “Milky Way”
Trade Name:“Milky Way”
Composition:filling: sugar, glucose syrup, vegetable fat, whole milk powder, skimmed milk powder, malt extract, salt, dried egg-white, natural identical flavoring (vanillin)
chocolate: sugar, milk powder, cocoa butter, cocoa mass, lactose, emulsifier (soy lecithin), milk fat, natural identical flavoring (vanillin)Also may contain insignificant amount of peanuts and hazelnuts Main properties:nougat, soft caramel and coated in milk chocolate Food category:chocolate bar
Production:considering the fact “Mars” is a modified version of “Milky Way”, the process of production is similar to that of “Mars” Significance:beneficial effects of chocolate include anticancer, brain stimulator, cough preventive, reduced risk of heart disease, anti-diarrhoea effect, also, chocolate bar filling (nougat) could serve as a supplement of sugar and calcium. On the other hand, excessive consumption may lead to obesity and sugar diabetes. Nutrition ratio:118 kcal, 4.7 % (assuming adult daily consumption is 2500 kcal) Nutrition facts:Sugar - 17.4 g; Fat - 4.4 g; Saturated Fat Acids - 2.5 g; Sodium - 56.39 mg (out of 26 g serving size) Metabolism:various studies suggest chocolate bars boost up human metabolic rate

Following calculations assume sum of saturated and desaturated fat as total fat, and energetic value of sodium as insignificant, also macro-nutrition facts are taken from Appendix A. |“Mars” |“Milky Way” | |a. Caloric content per serving size (35 g): |a.

e. Following table explains the difference in nutrients between “Mars” and “Milky Way”
|Nutrient |“Mars” |“Milky Way” |Difference* | |Carbohydrate |21.7 g |17.4 g |- 19.8 % | |Fat |10.1 g |6.7 g |- 33.7 % | |Sodium |50.2 mg |56.39 mg |+ 12.3 % | |Calories |199.3 kcal |129.9 kcal |- 34.8 % |
*”Mars” nutrients data was used as 100 %
Based on the above-mentioned findings, I would like to point out that in both cases (“Mars” and ”Milky Way”) nutrition facts claimed by manufacturer differed from calculated. Since the primary serving sizes are relatively small (35 g and 26 g respectively), adult person would find it harmless to consume 1-2 chocolate bars. Both products contain high amounts of carbohydrates (more than 50 % of the weight), which serve as primary source of energy supply in human body, could be used to partially satisfy recommended daily calories intake. Although, one should be aware of the dangers of excessive consumption of chocolate bars, outlined in theoretical part (e.g. mere five “Mars” bars could give 50 % of daily caloric need). In conclusion, I would suggest consumption of “Milky Way” over “Mars” bar since the latter has higher deviation of calculated and claimed calories per serving size (9 % vs. 20 % respectively) and “Milky Way” has higher sodium concentration. In other words, if one might feel an urge to eat a chocolate bar, he/she should choose “Milky Way”. References
