Barwy spożywcze i nadpobudliwość
Zapobieganie i profilaktyka

Analiza literatury naukowej wskazuje na istotny, choć niewielki efekt sztucznych barwników spożywczych (AFC) na nasilenie objawów nadpobudliwości u dzieci, ze wskaźnikiem efektu 0,283 (95% CI 0,079–0,488). Szczególnie barwniki takie jak Czerwień 40 (Allura Red), Żółcień 5 (Tartrazyna) oraz Czerwień 3 są powiązane z pogorszeniem koncentracji i wzrostem nadpobudliwości. Badania, w tym metaanalizy i raporty instytucji takich jak OEHHA, potwierdzają związek między ekspozycją na AFC a objawami neurobehawioralnymi, w tym nieuwagą, nadaktywnością i lękiem. Interwencje dietetyczne, takie jak eliminacja barwników na okres 2-4 tygodni, wykazały poprawę zachowania u około 75% dzieci wrażliwych, co podkreśla potencjał diety eliminacyjnej jako elementu terapii wspomagającej u pacjentów z ADHD i innymi zaburzeniami zachowania.

Związek między barwnikami spożywczymi a nadpobudliwością u dzieci stanowi istotny problem zdrowia publicznego, który był przedmiotem badań naukowych przez ponad 35 lat. Choć nie ma jednoznacznych dowodów, że sztuczne barwniki spożywcze (AFC – Artificial Food Colors) są główną przyczyną ADHD, zgromadzone dane sugerują, że mogą one nasilać objawy u dzieci z tym zaburzeniem, a także powodować problemy behawioralne u dzieci bez diagnozy ADHD12.

Podstawy naukowe działań profilaktycznych

Przegląd dostępnych badań wskazuje na niewielki, ale istotny negatywny wpływ sztucznych barwników spożywczych na zachowanie dzieci. Metaanaliza badań wykazała, że ogólny efekt AFC na nadpobudliwość wynosi 0,283 (95% CI, 0,079 do 0,488)34. Badanie z Uniwersytetu Southampton wykazało zwiększony poziom nadpobudliwości u dzieci spożywających mieszanki pewnych barwników spożywczych i benzoesanu sodu5. Szczególnie godne uwagi było badanie przeprowadzone w 2007 roku przez brytyjską Agencję Standardów Żywności, które wykazało, że spożycie żywności zawierającej barwniki może zwiększać zachowania nadpobudliwe u dzieci6.

Kalifornijski Urząd Oceny Zagrożeń dla Zdrowia Środowiskowego (OEHHA) w 2021 roku opublikował raport stwierdzający, że istnieje związek między ekspozycją na syntetyczne barwniki spożywcze a negatywnymi skutkami neurobehawioralnymi u dzieci, w tym nieuwagą, nadaktywnością i niepokojem78. Ponadto sześciotygodniowe badanie z udziałem 200 dzieci na diecie wolnej od syntetycznych barwników wykazało poprawę zachowania u 150 z nich9.

Działania w zakresie zdrowia publicznego

W odpowiedzi na rosnące dowody naukowe, niektóre kraje podjęły już kroki w celu ograniczenia stosowania sztucznych barwników w żywności dla dzieci. Unia Europejska od 2010 roku wymaga, aby produkty zawierające pewne sztuczne barwniki nosiły następujące ostrzeżenie: „Może mieć negatywny wpływ na aktywność i uwagę u dzieci”1011. W Wielkiej Brytanii rząd poprosił producentów żywności o unikanie tych dodatków na rzecz naturalnych barwników i aromatów1.

W 2023 roku Kalifornia stała się pierwszym stanem w USA, który zakazał sześciu sztucznych barwników spożywczych w posiłkach serwowanych w szkołach publicznych7. Amerykańska Akademia Pediatrii (AAP) wydała również oświadczenie, że niektóre obecnie dozwolone chemikalia powinny być unikane, szczególnie przez dzieci12.

Barwniki spożywcze, które należy ograniczyć

Szczególną uwagę warto zwrócić na następujące barwniki, które najczęściej wiązane są z nadpobudliwością:

Podejście dietetyczne w profilaktyce

Liczne badania sugerują, że ograniczenie lub eliminacja sztucznych barwników spożywczych może być skuteczną metodą profilaktyki i łagodzenia objawów nadpobudliwości u dzieci wrażliwych na te substancje1819. Chociaż dieta eliminacyjna może nie być rozwiązaniem dla wszystkich, stanowi strategię wartą rozważenia, szczególnie w przypadku dzieci wykazujących objawy nadpobudliwości po spożyciu barwnej żywności20.

Zalecane działania profilaktyczne obejmują:

  • Minimalizowanie ekspozycji dzieci na sztuczne barwniki spożywcze2119
  • Wybieranie świeżych, nieprzetworzonych produktów spożywczych820
  • Dokładne czytanie etykiet produktów – barwniki są zwykle wyraźnie oznaczone kodem i numerem7
  • Wybieranie produktów oznaczonych jako wolne od sztucznych barwników22
  • Zwracanie uwagi na leki dla dzieci (np. syropy przeciwkaszlowe, tabletki do żucia), które również mogą zawierać barwniki23

Testowanie diety eliminacyjnej

W celu sprawdzenia, czy barwniki spożywcze wpływają na zachowanie dziecka, można przeprowadzić test diety eliminacyjnej pod nadzorem specjalisty. Polega on na wykluczeniu wszystkich sztucznych barwników z diety na okres 2-4 tygodni, a następnie obserwacji zmian w zachowaniu1013.

Badania wykazały, że gdy brytyjscy naukowcy testowali barwniki spożywcze i konserwanty, 79% badanych dzieci wykazało reakcję na barwniki spożywcze10. Gdy dzieci zostały umieszczone na specjalnej diecie eliminacyjnej, wykluczającej pokarmy wywołujące niepożądane zachowania, nawet 30% maluchów i przedszkolaków wykazało korzyści10.

Indywidualne podejście do profilaktyki

Należy pamiętać, że reakcje na barwniki spożywcze są indywidualne i nie wszystkie dzieci są jednakowo wrażliwe24. Jeśli zauważysz, że Twoje dziecko staje się nadpobudliwe, rozdrażnione lub ma problemy z koncentracją po spożyciu żywności zawierającej sztuczne barwniki, warto rozważyć ich ograniczenie2526.

Szczególnie wrażliwe mogą być dzieci z następującymi rozpoznaniami:27

  • ADHD – barwniki mogą nasilać objawy zaburzenia
  • Zaburzenia zachowania opozycyjno-buntownicze – barwniki mogą nasilać zachowania buntownicze
  • Zaburzenia lękowe – barwniki mogą wpływać na bakterie jelitowe, co może nasilać objawy lękowe

Holistyczne podejście do profilaktyki

Warto zaznaczyć, że samo wyeliminowanie barwników spożywczych nie jest panaceum na ADHD czy nadpobudliwość, które są złożonymi zaburzeniami o wieloczynnikowym podłożu2829. Zalecane jest holistyczne podejście do profilaktyki, które obejmuje:

  • Zdrową dietę opartą na nieprzetworzonych produktach20
  • Odpowiednią ilość snu27
  • Regularną aktywność fizyczną27
  • Wsparcie specjalistyczne w przypadku diagnozowanych zaburzeń

Wskazówki dla personelu medycznego

Lekarze i inni specjaliści ochrony zdrowia odgrywają kluczową rolę w edukacji pacjentów i ich rodzin na temat potencjalnego wpływu barwników spożywczych na zachowanie dzieci79.

Zalecenia do praktyki klinicznej

W pracy z pacjentami warto uwzględnić następujące elementy:1922

  • Informowanie rodziców dzieci z ADHD i innymi zaburzeniami zachowania o potencjalnym wpływie barwników spożywczych na objawy
  • Sugerowanie prowadzenia dziennika żywieniowego w celu identyfikacji związków między spożyciem barwników a zmianami w zachowaniu
  • Wspieranie pacjentów i ich rodzin w podejmowaniu prób diety eliminacyjnej pod odpowiednim nadzorem
  • Edukacja na temat czytania etykiet produktów spożywczych
  • Rekomendowanie wersji leków bez barwników dla wrażliwych pacjentów

Monitorowanie i kontynuacja opieki

W przypadku pacjentów decydujących się na ograniczenie spożycia barwników spożywczych, zaleca się regularne monitorowanie efektów takiego podejścia3031. Warto zwrócić uwagę na:

  • Zmiany w zachowaniu i nasileniu objawów nadpobudliwości
  • Trudności w przestrzeganiu diety i sposoby ich przezwyciężania
  • Ogólny stan zdrowia i samopoczucie pacjenta
  • Potrzebę modyfikacji innych aspektów leczenia (np. dawkowania leków)

Edukacja i zasoby dla pacjentów

Personel medyczny powinien zapewnić pacjentom i ich rodzinom rzetelne informacje oraz dostęp do zasobów edukacyjnych dotyczących barwników spożywczych i ich potencjalnego wpływu na zachowanie830. Mogą to być:

  • Materiały informacyjne na temat najczęściej stosowanych barwników i ich występowania w żywności
  • Lista produktów spożywczych które często zawierają sztuczne barwniki (np. kolorowe słodycze, napoje gazowane, płatki śniadaniowe)
  • Przykładowe jadłospisy dla diety z ograniczeniem barwników spożywczych
  • Wskazówki dotyczące zdrowych alternatyw dla produktów zawierających barwniki

Perspektywy na przyszłość

Mimo że dowody na związek między barwnikami spożywczymi a nadpobudliwością są znaczące, wciąż istnieje potrzeba dalszych badań w tym obszarze132.

Potrzeby badawcze

Przyszłe badania powinny skupić się na:733

  • Dokładniejszym określeniu mechanizmów, przez które barwniki spożywcze mogą wpływać na zachowanie
  • Identyfikacji czynników genetycznych i środowiskowych, które mogą zwiększać wrażliwość na barwniki
  • Ocenie długoterminowych skutków ekspozycji na barwniki spożywcze
  • Badaniu wpływu barwników na inne aspekty zdrowia psychicznego i fizycznego
  • Opracowaniu skutecznych metod identyfikacji osób wrażliwych na barwniki

Zmiany regulacyjne i polityczne

W świetle rosnących dowodów naukowych, istnieje potrzeba ponownej oceny obecnych przepisów dotyczących stosowania barwników spożywczych348. Możliwe kierunki zmian obejmują:

  • Obniżenie dopuszczalnych poziomów barwników w żywności, szczególnie w produktach przeznaczonych dla dzieci
  • Wprowadzenie ostrzeżeń na etykietach produktów zawierających barwniki powiązane z nadpobudliwością
  • Zachęcanie producentów żywności do stosowania naturalnych alternatyw dla sztucznych barwników
  • Wprowadzenie ograniczeń dotyczących marketingu produktów zawierających sztuczne barwniki, skierowanego do dzieci

Odpowiedź przemysłu spożywczego

W odpowiedzi na obawy konsumentów i rosnące dowody naukowe, wiele firm spożywczych już teraz podejmuje kroki w kierunku eliminacji sztucznych barwników ze swoich produktów3536. Ta tendencja prawdopodobnie będzie się nasilać w przyszłości, prowadząc do szerszej dostępności produktów wolnych od sztucznych barwników.

Podsumowanie

Profilaktyka nadpobudliwości związanej z barwnikami spożywczymi powinna opierać się na ostrożnym i świadomym podejściu do diety, szczególnie w przypadku dzieci wykazujących wrażliwość na te substancje119. Choć sztuczne barwniki nie są główną przyczyną ADHD, coraz więcej dowodów wskazuje, że mogą one przyczyniać się do nasilenia objawów nadpobudliwości u niektórych dzieci2237.

Minimalizowanie ekspozycji na sztuczne barwniki spożywcze, szczególnie u dzieci z ADHD lub innymi zaburzeniami zachowania, oraz promowanie diety opartej na nieprzetworzonych, naturalnych produktach, może przynieść korzyści w zakresie kontroli objawów nadpobudliwości1020. Jednak ważne jest, aby takie działania były częścią kompleksowego podejścia do zdrowia, obejmującego odpowiednią ilość snu, regularną aktywność fizyczną i, w razie potrzeby, odpowiednie leczenie medyczne27.

Dalsze badania nad wpływem barwników spożywczych na zachowanie dzieci są niezbędne, aby lepiej zrozumieć ten związek i opracować skuteczniejsze strategie profilaktyki i leczenia3233. Tymczasem, zgodnie z zasadą ostrożności, rozsądne wydaje się ograniczenie ekspozycji dzieci na sztuczne barwniki spożywcze, szczególnie tych, które mogą być na nie wrażliwe21.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC3441937/
    The effect of artificial food colors (AFCs) on child behavior has been studied for more than 35 years, with accumulating evidence from imperfect studies. […] Recent data suggest a small but significant deleterious effect of AFCs on children’s behavior that is not confined to those with diagnosable ADHD. […] AFCs appear to be more of a public health problem than an ADHD problem. […] AFCs are not a major cause of ADHD per se, but seem to affect children regardless of whether or not they have ADHD, and they may have an aggregated effect on classroom climate if most children in the class suffer a small behavioral decrement with additive or synergistic effects. […] The results of these studies led to some significant changes in the field of public health, with the United Kingdom government requesting that food manufacturers avoid these additives in favor of natural food colors and flavors, and the EU asking manufacturers to voluntarily remove several AFCs from foods and beverages or list the following warning on the label: [this AFC] may have an adverse effect on activity and attention in children. […] The current status of evidence is inconclusive but too substantial to dismiss. […] Until safety can be better determined, we suggest minimizing children’s exposure to AFCs.

    https://www.everydayhealth.com/adhd-pictures/how-food-can-affect-your-childs-adhd-symptoms.aspx
    Many parents wonder if artificial food additives and colorings contribute to ADHD. Though the causes of ADHD are still unknown, you can try removing the sources of artificial colorings and food additives, including sugar-sweetened drinks, candy, and colorful cereals, and determine if your child’s behavior improves. […] Some frozen brands contain artificial colors, so check all labels carefully. Barnhill says some frozen foods can exacerbate ADHD symptoms for another reason: Foods treated with organophosphates for insect control have been shown to cause neurologic-based behavioral problems that mimic ADHD and many other behavior problems. […] Energy drinks are high on the list of things that cause teens to display behaviors mimicking ADHD, says Barnhill. They have no place in a healthy ADHD diet.

    Burgeoning estimates of the prevalence of childhood attention-deficit/hyperactivity disorder (ADHD) raise the possibility of a widespread risk factor. We seek to assess whether artificial food colorings (AFCs) contribute to the behavioral symptomatology of hyperactive syndromes. […] Meta-analytic modeling determined the overall effect size of AFCs on hyperactivity to be 0.283 (95% CI, 0.079 to 0.488), falling to 0.210 (95% CI, 0.007 to 0.414) when the smallest and lowest quality trials were excluded. Trials screening for responsiveness before enrollment demonstrated the greatest effects. Despite indications of publication bias and other limitations, this study is consistent with accumulating evidence that neurobehavioral toxicity may characterize a variety of widely distributed chemicals. Improvement in the identification of responders is required before strong clinical recommendations can be made.

    A study by researchers at the University of Southampton has shown evidence of increased levels of hyperactivity in young children consuming mixtures of some artificial food colours and the preservative sodium benzoate. […] The results of the Southampton study show that when the children were given the drinks containing the test mixtures, in some cases their behaviour was significantly more hyperactive. […] Professor of Psychology, Jim Stevenson, who led the research, comments: „We now have clear evidence that mixtures of certain food colours and benzoate preservative can adversely influence the behaviour of children. […] We have now shown that for a large group of children in the general population, consumption of certain mixtures of artificial food colours and benzoate preservative can influence their hyperactive behaviour. […] However parents should not think that simply taking these additives out of food will prevent all hyperactive disorders.

    A study of nearly 300 children by the United Kingdoms Food Standards Agency in 2007 showed that the consumption of foods containing dyes could increase hyperactive behavior in children. […] The researchers found that hyperactive behavior by the 8- and 9-year-olds increased with both the mixtures containing artificial coloring additives. The hyperactive behavior of 3-year-olds increased with the first beverage but not necessarily with the second. They concluded that the results show an adverse effect on behavior after consumption of the food dyes.

    In September, California became the first state in the nation to ban six artificial food dyes from meals served in public schools. […] The move followed a 2021 report from the state’s Office of Environmental Health Hazard Assessment (OEHHA) that concluded the body of evidence supported a relationship between food dye exposure and adverse behavioral outcomes in some kids. […] „It is primarily based on that human evidence that we have reached this conclusion that food dyes cause behavioral problems in some kids, and that is backed up by the animal evidence and the mechanistic evidence,” Galligan said. […] „I don’t think we need more research. I think the evidence is crystal clear that food dyes are causing behavioral problems in some kids.” […] „What happens with pharmacokinetics? How much is absorbed? How is it metabolized? In children, and I think also examining some of these issues in adults will be beneficial.”

    „We decided to do this study because nobody had really looked at young adults,” Holton said. […] „It might be that cognitive behavioral effects are kind of the tip of the iceberg. There may be other things going on underneath that are deleterious to health” — including potential carcinogenicity. […] „I would urge pediatricians, and other healthcare providers, particularly those interacting with children and their families, to really be mindful of the potential impacts that dyes are having.” […] For individuals who are concerned, Holton recommends avoiding foods that contain artificial dyes, which are easy to identify on food labels with a color and number indicating the dye clearly stated, she said. They can then see for themselves if they notice any behavior changes.

    Foods containing synthetic food dyes make children vulnerable to hyperactivity and other behavioral problems, according to a new report by California state scientists. […] OEHHAs report concluded that human studies show that dyes are associated with inattentiveness, hyperactivity and restlessness in sensitive children. […] OEHHAs findings concluded that currently allowed levels are not protective of childrens health and need to be much lower. […] The FDA and state health agencies need to act so another generation of children is not at risk of developing serious behavioral problems that will affect them throughout their lives. […] EWG recommends caregivers limit childrens consumption of food dyes and other harmful food additives by: Avoiding food products with these ingredients. Choose fresh, whole foods when possible, and limit packaged foods, especially those that are artificially colored and marketed to kids. Choosing organic foods. The Department of Agriculture does not permit the use of artificial colors in foods it certifies as USDA organic. Reading labels carefully. Food dyes may be in more foods than you think and even in seemingly healthy foods, such as dried food snacks. Avoid products that list FDC dyes or the words artificial color on the label. Let EWGs Food Scores help you find better choices. Speaking up. Join parents and consumer advocacy groups in petitioning for warning labels. Contact food manufacturers to ask them to remove artificial colors from foods marketed directly to children.

    The Food and Drug Administration has over 3000 ingredients listed on its database of additives that are permitted in US food items. Out of this number, nine of them are approved synthetic food coloring. Food colors and additives have been a topic of increasing concern, especially with the rise of neurocognitive conditions among our young. […] A great example was seen in a 6-week trial of 200 kids who went on a synthetic color-free diet. During the study, 150 of the children showed improvements in behavior while on the diet. […] Taking a deeper look into the food coloring and additives that children are exposed to can shed light on areas of nutritional implications and ADHD. […] Pertaining to ADHD, colorants and chemical additives have become a mainstream medical topic for their potential implication on neurocognitive function. When it comes to food coloring, FDC Red 40 is the most scrutinized dye. A 2020 report from the California Environmental Protection Agency expressed that intake of synthetic dyes in some children may be associated with behavioral signs, including inattentiveness, hyperactivity, and restlessness. […] Multiple studies have been geared towards the combo effect of food coloring with the additive Sodium Benzoate. […] Another interesting elimination diet investigation took 26 children who met the diagnosis of ADHD and eliminated multiple food preservatives and food colorings. […] On the placebo days, there was a significant improvement in their symptoms compared to food additive days.

    Many of the other food additives may impact gut health and a child’s microbiome, which can have an effect on brain health. […] Potential impacts on the microbiota have been assessed when it comes to the mentioned categories of food additives. […] Gut-brain connection has a contributory effect on ADHD, as many of our neurotransmitters are made in the gut. […] Dietary implications for ADHD should be considered, as evidence suggests there may be a correlation. […] If you suspect your kid is reacting to dyes or additives in foods, working with a healthcare provider can help you get to the root cause of this issue.

    Research suggests that artificial food dyes, sugar, and sensitivities may exacerbate symptoms of ADHD in some children. […] Studies published in The Lancet, Pediatrics, and Journal of Pediatrics suggest that food additives adversely affect a population of children with ADHD. […] Some even indicate that artificial coloring and flavors, as well as the preservative sodium benzoate, can make even some kids without ADHD hyperactive. […] Starting in 2010, the European Union required the following warning label for all food that contains artificial dye: “May have adverse effect on activity and attention in children.” […] The Center for Science and the Public Interest petitioned the Food and Drug Administration (FDA) to hold a hearing on whether the U.S. should require a similar warning label — or ban artificial colors altogether.

    However, the FDA did admit that a population of children does react adversely to these dyes. […] If you consume orange soda in the U.S., you’re consuming red #40 and yellow #5. […] How do you know if food additives are compromising your child’s focus? Conduct a quick test at home. […] When the British researchers tested food dyes and preservatives, 79 percent of the children tested had a reaction to the food dyes. […] When placed on a special elimination diet excluding foods that trigger unwanted behavior, as many as 30 percent of toddlers and preschoolers benefit. […] The benefits for adults with ADHD are less clear. […] Studies failed to uphold Feingold’s claims when he first made them, and most ADHD experts still dismiss the Feingold diet as ineffective. […] Yet some recent research suggests that the Feingold diet may, indeed, benefit the small percent of children with ADHD who seem sensitive to chemicals in food.

    The conclusion? Artificial colors do react adversely with ADHD symptoms in some children. […] However, all studies on the effect of elimination diets on ADHD symptoms found statistically significant ADHD symptom reduction when children were given a narrow diet of foods unlikely to cause reactions. […] Avoiding foods with artificial colors and preservatives has another big benefit: It will raise the nutritional value of your family’s diet, since the “junkiest” foods on supermarket shelves tend to be — you guessed it — the most heavily colored and flavored.

    An enduring controversy in the ADHD world is the role of diet and, in particular, synthetic food dyes. […] In contrast, beginning in 2010, European Union countries have added a warning label to foods containing synthetic dyes indicating they may increase inattention or hyperactivity. […] Overall, we confirmed that food dyes increase ADHD symptoms somewhat. […] This suggests that to the extent that food dyes affect ADHD symptoms, this is a public health concern that is not ADHD-specific. […] My own view is that food dyes are not proven safe for children, and certainly may increase symptoms of inattention or hyperactivity. For some children, this may be one too many challenges to their nervous system and contribute to ADHD symptoms. […] Thus, given they have little value, I recommend parents avoid these food dyes if they can.

    According to the statement in the August 2018 Pediatrics, „Food Additives and Child Health”, some currently allowed chemicals may best be avoided–especially for children. […] Artificial food colors, common in children’s food products, may be associated with worsened attention-deficit/hyperactivity disorder (ADHD) symptoms. Studies cited in the report found a significant number of children who cut synthetic food colorings from their diets showed decreased ADHD symptoms. […] Potentially harmful effects of food additives are of special concern for children, according to the AAP. Children are more sensitive to chemical exposures because they eat and drink more, relative to body weight, than adults do, and are still growing and developing. […] „Chemicals that affect the endocrine system, for example, can have lasting effects on a child since hormones coordinate complex functions throughout the body,” Dr. Trasande said. „Even small disruptions at key moments during development can have lifelong consequences,” he said.

    Research suggests that synthetic food coloring affects ADHD symptoms in some children. […] Irritability. Extreme hyperactivity. Explosive anger. Anxiety, or even despondency. If you’ve noticed a spike in undesirable emotions and behaviors after your child eats a bowl of Fruit Loops or a handful of M&Ms — and suspected a link between their ADHD symptoms and diet — you are not alone. […] With growing frequency, parents are noting a connection between their children’s behavior and their consumption of food containing synthetic dyes — namely, red #3, red #40, and yellow #5. […] Based on research, including Nigg’s own review of the literature in 2012, restricting the consumption of synthetic food dyes does benefit some children with ADHD. […] Nigg and the others are now encouraging similar action from the FDA, which has reviewed the research several times since 2011 and decided to take limited action on food dyes.

    Dr. Nigg: In my opinion, there is enough evidence that food dyes affect behavior in some sensitive children with ADHD (and other children without the condition) to justify warning labels on foods containing synthetic dyes. […] Food dyes have not been proven safe for children, and they may increase symptoms of inattention or hyperactivity. […] Parents are well-advised to remove food dyes from their child’s diet if they can. […] Some children may experience more aggression and hyperactivity, and reduced attention and focus. […] Although many children who are sensitive to food dyes are also sensitive to other elements in food, food dyes are a straightforward target. […] Should parents avoid food dyes? If possible, you can remove one of the many potential negative factors. […] If you feel you want to try to avoid synthetic food dyes, steer clear of most processed and packaged foods.
