Sunset yellow belongs to a group of so-called azo dyes. In very rare individual cases, it can cause allergic skin reactions in sensitive people, such as rash, eczema, or hives, and can also lead to shortness of breath and asthma-like attacks. Hyperactivity and attention deficits in children can be exacerbated by sunset yellow. In the so-called Southampton study published in England in 2007, a double-blind and placebo-controlled direct association was found between the dietary intake of dyes, such as sunset yellow S, and benzoic acid (E 210–213) and the hyperactive behavior of children between the ages of three and eight to nine years. In the European Union the substance must carry a warning: "May impair attention and activity in children”. In 2009, the European Food Safety Authority (EFSA) lowered the so-called ADI value from a maximum of 2.5 milligrams per kilogram of body weight to 1 milligram per kilogram on the basis of the state of research at the time, combined with the demand for further tests on the hazard potential. Based on recent studies, a much higher ADI of 4 milligrams has been in force since 2014. EFSA considered that there was no risk and that even this new, higher ADI was well below the estimated daily intake of this additive. But the dye sunset yellow S continues to be criticized. In a toxicological study published in 2021, a test-tube test showed that it has a damaging effect on the mucous membrane of the small intestine, which could potentially also result in inflammation of the intestine. The dye may also contain aluminum. The metal is suspected of promoting dementia in the brain, such as Alzheimer's and Parkinson's disease, but also hyperactivity and attention disorders. It can also act like a female sex hormone and is therefore one of the so-called metal estrogens. As such, it can affect sexual functions and contribute to obesity. Aluminum can also impair intestinal functions. It can change the composition of bacteria in the digestive tract (the so-called microbiome) and disrupt the immune system. Experiments with mice have shown that it promotes inflammation and promotes so-called irritable bowel syndrome.
Sunset yellow S is found in confectionery, such as marzipan. It works well for yellowish desserts and baked goods. Jams look fruitier and canned fruit look fresher due to sunset yellow. Ready-made soups and sauces are also embellished with this dye.
Sunset yellow S is an artificial dye from the group of so-called azo dyes. It is artificially produced from petroleum derivatives. The substance is very stable against fruit acids, light, and heat and is therefore versatile. It is most soluble in water. In certain manufacturing processes, it may also contain aluminum, in which case it belongs to the group of so-called aluminum lake colors. Orange Yellow S, CI Food Yellow 3, FD&C Yellow No. 6

About the DR. WATSON Database of Additives
Carefully researched, factual, understandable: The DR. WATSON database provides reliable information on industrial additives in food. The data in the DR. WATSON database are based on the official accounts of the responsible authorities, but show a comprehensive picture and also report on research results of independent and recognized institutions around the world.
DR. WATSON was the first information service to evaluate additives, conduct its own research, consult thousands of studies and analyze them uniformly according to the criteria of evidence-based medicine. Our approach is clearly defined and transparent.
In this process, the DR. WATSON team was supported by recognized scientists and also sought legal advice. The DR. WATSON database is regularly updated and expanded. DR. WATSON is independent of outside interests and institutions.
Dr. WATSON consistently looks at novel ingredients of food from the perspective of consumers. The DR. WATSON database of additives provides information not only on additives and their health implications but also on their distribution: after all, it comes down to individual decisions of consumers on the basis of personal preferences and inclinations.
Important information on risks of additives in industrial food
DR. WATSON’s database of food additives does not give medical advice or recommendations. The DR. WATSON database provides information about additives – independent, scientifically sound, comprehensible.
Officially, additives in industrial food are considered harmless. So if you eat little of it and are of a robust constitution, you have nothing to worry about. (For allergies, however, a milligram of the wrong thing can be fatal.)
With the limits being raised for what are considered safe consumption amounts, the chemical additives in food are becoming a health risk for more and more people. For many additives, side effects are proven beginning at a certain amount – and those side effects can be more severe than previously suspected. Especially children consume more of such additives than is good for them (ADI).
These are risks that humans have created for themselves. They are not impurities stemming from contamination or spoilage, but intentionally added additives.
The additives in such foods do not serve the consumers but the manufacturers of industrial food.
Their primary purpose is to extend shelf life and reduce costs. The human organism does not need such chemicals. They also have no health benefits for consumers. Many of the additives can pose health risks.
Chemically produced additives, unlike normal ingredients such as cauliflower, cream, or chicken, are not traditional components of a dish or a food. The body therefore has no adequate, evolutionarily practiced mechanisms for processing them.
Humans do not need additives. Only the food industry needs them.
They serve to enhance the taste or color of industrial food – externally. More colorful effervescence, browner sauces, noodle soups with longer shelf life, airier cakes, rolls with enhanced bun scent, creamier cream cheese with less fat, yogurts with stabilized fruit pieces that don’t move around.
Industrial food is designed to appear more attractive — and for as long as possible (shelf life). Because in the world of factories and supermarkets, food has to be cheap and last an unnaturally long time which is only possible by means of chemical engineering.
Many industrial foods cannot do without additives. Bag soups would quickly mold, margarine would become rancid, fruit yogurts would separate into fruit preparation and yogurt. Ready-made salad dressings would disintegrate into its components of herbs, vinegar, and oil.
The chemical substances indicated with E numbers are essential for industrial food production.
Many of them were tailored to the needs of food factories, lab-made substances without a model in nature. Other substances used do occur in nature but by using them as additives, the quantities that are being consumed have grown disproportionately.
In the past, doctors and authorities have therefore expressed concerned about these chemical substances in food, especially in the case of sustained and long-term intake.
Since then the official stance has changed.
Substances that were once considered "xenobiotics" and were even reviled by experts as "poisons" have now not only been rehabilitated, but even ennobled. Although consumer deception is still officially banned, they are now considered "food improvement agents" (EU jargon). To regulate the handling of these noble ingredients, the European Union has adopted a whole quartet of regulations, the "Food Improvement Agents Package" (FIAP), consisting of four individual regulations on the different types of additives.
However, findings on the harmful effects of these "substances for the improvement of food" are increasing.
Flavour enhancers such as glutamate are suspected of contributing to diseases such as Alzheimer's and Parkinson's. Dyes can lead to hyperactivity and learning disorders (ADHD). Migraines can also be triggered by food additives. Sweeteners such as aspartame are even suspected of causing cancer. Preservatives can damage the intestines and disrupt the immune system. Citric acid can attack the teeth and also transport harmful metals such as aluminum into the brain. Industrial flavors can cause obesity. Phosphates can accelerate the aging process and cause diseases such as heart disease, high blood pressure, bone weakness, and osteoporosis to occur earlier in life.
Additives are only used in tiny doses. However, more and more substances are being authorized and the individual additives are being produced in ever larger quantities. Phosphates, for example, are used worldwide as food additives at a rate of over 300,000 tonnes per year. In the case of sweeteners, the annual figure is 750,000 tonnes. Citric acid is one of the record holders: About 3 million tons are produced worldwide every year, most of it for food. In the case of glutamate, it is even 3.3 million tons per year.
Surprisingly, the effects of the individual chemicals multiply when consumed jointly. This was shown, among other things, by a study conducted by the University of Liverpool with the two dyes E104 (quinoline yellow) and E133 (brilliant blue), the flavor enhancer glutamate (E621), and the sweetener aspartame (E951).
The result: The harmful effects of the additives on the brain (neurotoxicity) did not add up, as would be expected, but multiplied. A mixture of the blue dye E133 and glutamate (E621), for example, did not slow down cell growth by 15.8 percent, as would have been expected, but by 46.1 percent. One plus one therefore does not equal to two, but up to six.
When approving additives, it is always taken into account what quantities of which foods people consume. In animal experiments a dose is then determined which is released as a daily tolerable amount. A safety margin is then applied, and the so-called "ADI value" is calculated ("Acceptable Daily Intake"). From this, a maximum quantity is fixed for each food. This should be calculated in such a way that the ADI value is not exceeded even with frequent consumption.
But with many additives, especially children but also adults apparently consume far more than is good for them. This was the result of studies conducted by the EU Commission and the member states and the European Food Safety Agency (EFSA).
The recording of consumption volumes in the European Union seems to have been systematically delayed, as has been criticized even by the European Court of Auditors. In a special report, it strongly criticized the lax surveillance practice.
Authorities can therefore not give an absolute guarantee of safety, since they know neither about the exact quantities used in individual foods nor about the total quantities actually consumed.
As a result, since the supervisory authorities refuse to guarantee protection against the risks posed by additives, consumers must protect themselves.
So everyone has to know for themselves what they want to expose themselves to.
DR. WATSON helps – with solid information about food additives and their alternatives.
Because it is quite simple, life without E-numbers. There is a safe way to get by without additives: Real food. Cooking for yourself using fresh ingredients.
There are no additives in real food.
Make the dressing for the salad yourself, cook the soup fresh or for a few days in advance, stir fruit or jam into the natural yoghurt.
It is: the traditional way of eating. In medicine, for example, the Mediterranean diet is now considered the gold standard for the prevention of diseases.
And: it is also the most enjoyable way of eating. Some even speak of a "gourmet diet", which is primarily oriented towards taste - and thus towards the neurological laws for the optimal supply of the individually necessary nutrients.
And: It is not only best for humans, but also for animals and the environment. And, of course, the children, and thus the following generations, the future of the planet.
