Introduction
1. In 2022, the Department for Environment, Food and Rural Affairs (Defra) held a consultation on the Bread and Flour Regulations (BFR) 1998 to increase the fortification level to allow harmonisation with EU retained Regulation (EU) No 1169/2011. Defra asked whether the consultees agreed with the proposal to raise the minimum levels of calcium carbonate, iron and niacin added to non-wholemeal flour to 15% of the nutrient reference values (NRV). The minimum amount of thiamin required to be present in non-wholemeal wheat flour would remain the same at 19% of the NRV. NRVs are established guidelines for the recommended daily energy and nutrient consumption.
2. The Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT) have been asked by the Department of Health and Social Care (DHSC) to provide an assessment on the dietary exposure of calcium carbonate, iron, nicotinic acid and thiamin (Vitamin B1) at current and proposed fortification levels. The exposure assessment should provide a comparison to the UK Expert Group on Vitamins and Minerals (EVM) safe levels and upper levels (UL) and assess whether there is a potential risk to human health from the proposed increased fortification in non-wholemeal wheat flour.
3. A paper (TOX/2022/48) was brought to the Committee in October. DHSC have requested that a statement be published with the conclusions of the Committee. Annex A contains the first draft statement for the consideration of the Committee.

Background
1. In 2022, the Department for Environment, Food and Rural Affairs (Defra) held a consultation on the Bread and Flour Regulations (BFRs) 1998 to increase the fortification level to allow harmonisation with EU retained Regulation (EU) No 1169/2011. Defra asked whether the consultees agreed with the proposal to raise the minimum levels of calcium carbonate, iron and niacin added to non-wholemeal flour to 15% of the nutrient reference values (NRV). The minimum amount of thiamin required to be present in non-wholemeal wheat flour would remain the same at 19% of the NRV. NRVs are established guidelines for the recommended daily energy and nutrient consumption.
2. The Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT) have been asked by the Department of Health and Social Care (DHSC) to provide an assessment on the dietary exposure of calcium carbonate, iron, niacin (nicotinic acid) and thiamin (Vitamin B1) at current and proposed fortification levels. The exposure assessment should provide a comparison to the UK Expert Group on Vitamins and Minerals (EVM) safe levels and upper levels (UL) and assess whether there is a potential risk to human health from the proposed increased fortification in non-wholemeal wheat flour.
Introduction
3. The BFR 1998 stipulates the levels of calcium carbonate, iron, thiamin (vitamin B1) and niacin (nicotinic acid) that are required to be present in all wheat flour other than wholemeal (i.e. non-wholemeal flour). Calcium is added in the form of calcium carbonate. Natural calcium found in food would not be present in the form of calcium carbonate. Therefore, exposure to calcium from fortified food can be distinguished from natural or supplementary sources when analysed. Niacin is added to flour using either nicotinic acid or nicotinamide.
4. The existing BFRs (1998) set a minimum fortification level for thiamin (vitamin B1) of 0.24 mg for thiamin hydrochloride, which is equivalent to 0.21 mg of thiamin or 19% of the NRV. The minimum fortification levels of calcium, iron and niacin have been set at 15% of the nutrient reference value (NRV) as stated in Annex XIII of regulation EC No. 1169/2011 (in point 1 of Part A). In practise, foods are not currently fortified at these respective levels, but industry are looking to increase fortification to the set minimum levels. The Daily NRVs for calcium carbonate, iron, niacin and thiamin (Vitamin B1) are 800, 14, 16 and 1.1 mg, respectively.
Toxicity
Calcium
5. High intakes of calcium carbonate of around 4,000 mg/day (equivalent to 1,600 mg calcium) can result in a condition called milk-alkali syndrome in people with underlying medical conditions such as peptic ulcers (EFSA, 2006). This condition is characterised by hypercalcaemia, alkalosis and renal impairment, which is associated with symptoms of hypertension, neurological problems, abdominal pain and tissue calcification (EVM, 2003).
6. Calcium supplements have been administered to people with colonic polyps or people who are at risk of colonic polyps. Gastrointestinal (GI) effects were reported in a small number of patients receiving 1,600 or 2,000 mg/day of calcium (EVM, 2003).
7. High calcium diets can affect the bioavailability of other minerals such as iron, zinc, magnesium and phosphorous by inhibiting the absorption of iron salts, haem-iron and zinc, reducing magnesium absorption and excretion, and the binding of calcium acetate and calcium carbonate to phosphate in the intestinal lumen (EFSA, 2006).
Iron
8. Iron toxicity is particularly hazardous in children and most poisoning cases are reported in children consuming iron supplements intended for adults. Symptoms in infants include gastrointestinal irritation at acute doses of around 20 mg/kg bw and other systemic effects which occur at doses <60 mg/kg bw. The lethal dose in children is between 200-300 mg/kg bw (EVM, 2003).
9. In adults, gastrointestinal effects such as constipation, nausea, vomiting and diarrhoea have been reported at therapeutic doses of 50-220 mg/day (EFSA, 2006). Iron toxicity can lead to inflammation and perforation of the gastrointestinal tract and iron disrupts the cellular metabolism in the central nervous system, liver and heart. Free iron in the serum, enters and concentrates in the mitochondria where it forms free radicals, which can impair energy metabolism and can eventually lead to cell death (Baranwal and Singhi, 2003; Yuen and Becker, 2022). However, iron poisoning in adults is rare, individual case reports suggest a lethal dose of 1,400 mg/kg bw (EVM, 2003).
Niacin (nicotinic acid/vitamin B3)
10. Symptoms of acute toxicity from niacin include flushing, itchy skin, nausea, vomiting and gastrointestinal issues (such as diarrhoea and constipation). Long term intakes of 3,000 mg/day of niacin have been reported to cause jaundice, hyperglycaemia and abdominal pain. In addition to elevated serum bilirubin, increased alkaline phosphatase and aminotransferase levels have been reported in a small number of cases. Anorexia, ophthalmological effects, skin hyperpigmentation and precipitation of incipient psychosis have also been reported as side effects of niacin therapy (EVM, 2003).
11. Patients with hypercholesterolaemia that have been treated with niacin at 3-9 g/day over a period of months to years showed symptoms of severe liver dysfunction which has the potential to be life threatening and may require liver transplantation (EFSA, 2006).
Thiamin
12. Thiamin is considered to be of very low toxicity with symptoms such as headache, nausea, irritability, insomnia, rapid pulse and weakness being seen at high oral doses of ≥7,000 mg thiamin hydrochloride (EVM, 2003).
13. However, a small number of case reports have shown association with adverse effects such as muscle tremors, rapid pulse and nerve hyperirritability at low daily doses of 17 mg/day of thiamin hydrochloride. In one case, a patient consuming thiamin at 100 mg/day for a period of 15 days, 2 months prior to consumption of a single oral dose of thiamin of 100 mg, experienced an anaphylactic reaction followed by death. In another case, a patient experienced exacerbated eczema after receiving an oral dose of 200 mg of thiamin in an experimental provocation (EVM, 2003).
14. Tolerable upper levels (TUL) nor safe upper levels (UL) have been established for calcium, iron, niacin (nicotinic acid) and thiamin by the Expert Group on Vitamins and Minerals (EVM) due to the lack of insufficient animal and human data (EVM, 2003).
15. However, the EVM stated that “1,500 mg/day of supplemental calcium would not be expected to result in any adverse effect, but that higher doses could result in adverse gastrointestinal symptoms in a few people” (EVM, 2003). Literature publicly available at the time of the COTs assessment (EVM, 2003) did not provide any new information or data indicating that any other level of calcium should be used as a safe UL. The Scientific Committee on Food (SCF) established a TUL of 2,500 mg/day for calcium in 2003 (SCF, 2003). This TUL was based on different long duration intervention studies in which total daily calcium intakes of 2,500 mg from both diet and supplements were tolerated without adverse effects and was endorsed by EFSA in 2012 (EFSA, 2012).
16. The EVM proposed that a supplemental intake of 17 mg/day for iron would not be expected to produce adverse effects in the majority of individuals. However, this guidance value does not apply to individuals who have an increased susceptibility to iron overload, a condition which is associated with a homozygous haemochromatosis genotype (with an estimated prevalence of up to 0.4% in the Caucasian population). An UL for iron has not been established by EFSA. The National Institutes of Health Office of Dietary Supplements in the United States have advised safe ULs of 40 mg/day for individuals aged 0 months to 13 years and 45 mg/day for individuals aged 14 years and over (Institute of Medicine, 2001). However, moderate symptoms of iron toxicity have been reported from 20 mg/kg bw/day (Madiwale and Liebelt, 2006). However, Madiwale and Liebelt (2006) reported that ingestion <20 mg/kg is non-toxic and moderate symptoms of iron toxicity can occur between 20 to 60 mg/kg.
17. The EVM proposed that a guidance level of 17 mg/day for niacin (nicotinic acid) would not be expected to result in any adverse effects. However, it was noted by the EVM that this guidance level is for supplementation only, as adverse effects from niacin seem to be related to acute, bolus intakes. Adverse effects from long term exposure of niacin in food would be less likely as free niacin levels in food are low. Additionally, the EVM noted that the guidance level is based on intakes of conventional formulations of niacin. This would not be applicable to sustained release preparations and niacin contained in dietary supplements is not in the sustained release form (EVM, 2003). In 2002, the SCF set an UL of 10 mg/day for niacin based on flushing of skin (EFSA, 2014).
18. The EVM proposed a guidance level for supplemental thiamin of 100 mg/day which would not be expected to result in adverse effects. The EVM noted however that this guidance level was only applicable to the water-soluble forms of thamin. Furthermore, the study by Gokhale et al. (1999), used to derive the guidance level, was conducted in young women (EVM, 2003). An UL for thiamin was not established by the SCF due to limited data on adverse effects in humans and lack of dose-response studies (EFSA, 2016). Whilst there is a lack of evidence of toxicity from a high intake of thamin from food or supplements (Martel et al., 2021), symptoms such as headache, nausea, irritability, insomnia, rapid pulse and weakness have been seen at high oral doses of ≥7,000 mg/day thiamin hydrochloride (EVM, 2003).
Exposure assessment
19. Exposures to calcium, iron, niacin and thiamin were determined using consumption data from the Diet and Nutrition Survey of Infants and Young Children (DNSIYC) and the National Diet and Nutrition Survey (NDNS). Levels of these nutrients in the entire diet were obtained from the nutrient databank (Bates et al., 2014, 2016, 2020; Roberts et al., 2018). Levels of nutrients in non-wholemeal flour used in the exposure assessment were those currently in use by industry. Exposure to the nutrients based on the proposed increases were also determined, except for thiamin, where no increases have been proposed. Table 2 provides information about current and proposed fortification levels for each nutrient where applicable. Exposure to these nutrients were calculated in Crème Global, the software that the FSA uses to interrogate dietary data and calculate exposure. Exposure estimates were derived by multiplying food consumption amounts by the levels of the nutrients in the foods. Chronic exposure or intake of these nutrients are presented. Chronic intake is derived from the average amount of flour consumed over the survey days multiplied by the levels of nutrients. Chronic exposure or intake is calculated for each consumer. The mean and P97.5 are then computed.

Methodology for estimating current and proposed exposures from non-wholemeal flour
20. Exposures based on current and proposed levels were calculated from foods containing non-wholemeal flour. This by definition is wheat flour without whole grain wheat. The recipe database associated with the NDNS food groupings identified foods containing non-wholemeal flour (n=1835). A selection of food groups (foods with non-wholemeal flour), each containing more than 20 foods are shown in Table A1 in Annex A.
21. The fortification level for thiamin remains unchanged, therefore exposures at the proposed fortification levels were only calculated for calcium, iron, and niacin.
22. Exposures to these nutrients from supplements were also considered. Data for supplements were obtained from market sources (e.g., websites of major retailers). Concentrations of calcium supplements ranged from 200-1200 mg for adults and 80-450 mg for children. Whereas concentrations of iron supplements ranged from 14-28 mg in adults and 2.8-7.5 mg in children. Concentrations of niacin supplements ranged from 50-1000 mg in adults and 4.8-20 mg in children. Ultimately, concentrations of thiamin supplements ranged from 100-500 mg for adults and 0.7-5 mg for children.
Exposures from the entire diet and from flour at the current and proposed fortification levels
23. Exposure to the nutrients from the entire diet was estimated using all food groups from NDNS years 1-11, which are presented in Table A2 of Annex B. All food groups including the foods containing non-wholemeal flour are detailed in paragraph 20. The levels of the nutrient for each of the foods included were derived from the nutrient databank from the NDNS.
24. Exposure to calcium, iron, niacin and thiamin from the entire diet and from flour fortification at current and proposed levels are shown in Table 2-5.
25. For calcium, across all age groups (4 months to 65+ years), the maximum mean and maximum 97.5th percentile exposures at the current level of fortification were 68 and 140 mg/person/day, respectively. The maximum mean and 97.5th percentile exposures at the proposed level of fortification are 87 and 180 mg/person/day, respectively. The maximum exposures to calcium from the entire diet are 820 and 1,600 mg/person/day at mean and 97.5 the percentile levels respectively (Table 3).
26. For iron, across all age groups (4 months to 65+ years), the maximum mean and maximum 97.5th percentile exposures at the current level of fortification are 1.2 and 2.5 mg/person/day respectively. The maximum mean and 97.5th percentile exposures at the proposed level of fortification are 1.5 and 3.2 mg/person/day respectively. The maximum exposures to iron from the entire diet are 10 and 19 mg/person/day at mean and 97.5th percentile levels respectively (Table 4).
27. For nicacin, across all age groups (4 months to 65+ years), the maximum mean and maximum 97.5th percentile exposures at the current level of fortification are 1.2 and 2.4 mg/person/day respectively. The maximum mean and 97.5th percentile exposures at the proposed level of fortification are 1.7 and 3.6 mg/person/day respectively. The maximum exposure to niacin from the entire diet are 36 and 68 at the mean and 97.5th percentile, respectively (Table 5).
28. For thiamin, across all age groups (4 months to 65+ years), the maximum mean and maximum 97.5th percentile exposures at the current level of fortification are 0.17 and 0.36 mg/person/day. The maximum exposure to thiamin from the entire diet are 1.5 and 2.8 mg/person/day at the mean and 97.5th percentile, respectively (Table 6).

Exposure from supplements
29. It should be noted that supplements data were derived from various online sources in Tables A5-A8 in Annex A. The exact consumption by the population was unknown therefore exposures were calculated based on recommended serving sizes.
30. Across all age groups (4 months to 65+ years) the upper exposures of supplemental calcium were up to 1,200 mg/day. In adults aged over 19 years, this exposure is equivalent to 1.48- and 0.75-fold the mean and 97.5th percentile calcium exposures from the entire diet (which includes all food groups including non-wholemeal flour), respectively.
31. Across all age groups (4 months to 65+ years) the upper exposures of supplemental iron were up to 28 mg/day. In adults aged over 19 years, this exposure is equivalent to 3- and 1.6-fold the mean and 97.5th percentile calcium exposures from the entire diet, respectively.
32. Across all age groups (4 months to 65+ years) the upper exposures of supplemental niacin were up to 1,000 mg/day. In adults aged over 19 years this exposure is equivalent of up to 32- and 19-fold of the mean and 97.5th percentile niacin exposures from the entire diet, respectively.
33. Across all age groups (4 months to 65+ years) the upper exposures of supplemental thiamin were up to 500 mg/day. In adults aged over 19 years, this exposure is equivalent to 330- and 185-fold the mean and 97.5th percentile thamin exposures from the entire diet.
Risk characterisation
Exposures from food
34. Chronic exposure of calcium at the current and proposed fortification levels (Table 3) did not exceed the guidance levels of 1,500 mg/day (EVM, 2003) and 2,500 mg/day (EFSA, 2012) across all age groups. Exposures from the entire diet were up to 1,600 mg/person day which although it exceeds the EVM guidance level, marginally, is below the SCF TUL of 2,500 mg/day.
35. Chronic exposures to iron at the current and proposed fortification levels (Table 4) did not exceed the guidance levels of 17 mg/day (EVM, 2003) across all ages. However, it is important to note that the guidance level is based on supplemental intake and does not apply to the population who have an increased susceptibility to iron overload. Moderate symptoms of iron toxicity have been reported to occur from 20 mg/kg bw per day (Madiwale and Liebelt, 2006). Exposures from the entire diet were up to 19 mg/person/day, which would result in marginal exceedance of the EVM guidance level but not the level reported to cause moderate symptoms of iron toxicity. It is not anticipated that there would be a risk to health from iron exposures in the entire diet to most of the population. However, the EVM guidance value does not apply to individuals who have an increased susceptibility to iron overload, a condition which is associated with a homozygous haemochromatosis genotype.
36. Chronic exposures to niacin equivalents (Table 5) at the current and proposed fortification levels did not exceed the guidance level for niacin of 17 mg/day (EVM, 2003) across all age groups. Exposures to niacin from the entire diet were up to 68 mg/person/day, which exceeds the EVM guidance level up to 4-fold. However, the EVM guidance level is for supplementation only, as adverse effects from niacin seem to be related to acute, bolus intakes. Adverse effects from long term exposure to niacin in food would be less likely as free niacin levels in food are low. It is unlikely that there would be a risk of adverse health effects at these exposures although there is some uncertainty because of the data used to establish the EVM guidance level: that it is intended for supplements, is based on a bolus intake and that the levels of free niacin in food are low.
37. Chronic exposures to thiamin at the current and proposed fortification levels (Table 6) did not exceed the current guidance level of 100 mg/day (EVM, 2003). Exposures to thiamin from the entire diet were up to 2.8 mg/person/day which were also below the EVM guidance level and it is unlikely that there would be a risk of adverse health effects.
Exposure from supplements
38. Daily exposure to calcium supplements did not exceed the EVM guidance level of 1,500 mg/day (EVM, 2003) or the SCF guidance level of 2,500 mg/day in adults and children (SCF, 2003). Exposure to higher dosage iron supplements (i.e., 28 mg/day) can exceed the guidance level of 17 mg/day (EVM, 2003) by up to 1.6-fold in adults. Daily exposure to niacin supplements could result in exceedances of the guidance level of 17 mg/day (EVM, 2003), by between 3- and 60-fold. For thiamin supplements, daily exposure could lead to up to a 5-fold exceedance of the guidance level of 100 mg/day (EVM, 2003).
Exposure from supplements and food
39. Mean calcium exposures from food (the entire diet and flour at the current and proposed fortification levels) and supplements (Table A3) were up to 2,000 mg/person/day, respectively and below either the EVM guidance level and/or the SCF TUL. Exposures associated with 97.5th percentile consumption were between 1,700 and 2,800 mg/person/day. For population groups below 19 years of age, the exposures are below the SCF TUL and it is unlikely that there would be a risk of adverse health effects. Population groups for 19 years and over marginally exceeded the SCF TUL and it is unlikely that there would be a risk of adverse health effects in humans at these exposures.
40. Mean and 97.5th percentile iron exposures from food and supplements were up to 20 mg/person/day which were either below or a minor exceedance of the guidance level of 17 mg/day (EVM, 2003) in those aged upto 18 years. There is unlikely to be a risk of adverse health effects in these populations due to exposures from iron. However, in the 19-64 and 65+ years age groups, mean and 97.5th percentile iron exposures were up to 38 and 47 mg/person/day which were exceedances of up to 2.2-fold and 2.8-fold, respectively. It is unlikely that there is a risk of adverse health effects. The EVM guidance value does not apply to individuals who have an increased susceptibility to iron overload, a condition which is associated with a homozygous haemochromatosis genotype.
41. Mean and 97.5th percentile niacin exposure from food (entire diet) and supplements exceeded the guidance level of 17 mg/day (EVM, 2003) across all age groups. In those aged up to 18 years exceedances of the 17 mg/day guidance level were up to 3- and 4.4-fold for mean and 97.5th percentile consumption, respectively. In individuals aged up to 3 years the exceedances were approximately half of these (up to 2.2- and .8-fold for mean and 97.5th percentile consumers, respectively). In those aged over 19 years the exceedances of the 17 mg/day guidance level were up to 59- and 65-fold for mean and 97.5th percentile consumers, respectively. Most of this exceedance comes from the consumption of supplements containing niacin at 1,000 mg.
42. As indicated in paragraph 36, the EVM guidance level is for supplementation only, as adverse effects from niacin seem to be related to acute, bolus intakes. Adverse effects from long term exposure to niacin in food would be less likely as free niacin levels in food are low. It is unlikely that there would be a risk of adverse health effects at the exposures from the entire diet, although there is some uncertainty because of the data used to establish the EVM guidance level. It is intended for supplements and is more considered for a bolus intake. It should also be noted that the levels of free niacin in food are low. Exposures from consumption of supplements containing high levels of niacin e.g. 1,000 mg could be at increased risk of adverse health effects, especially when consumed consistently over a prolonged period of time.
43. Exposures to thiamin for all age groups below 18 years of age are below the guidance level of 100 mg/day (EVM, 2003). Mean and 97.5th percentile intakes from food and supplements only exceeded the guidance level for thiamin of 100 mg/day (EVM, 2003) in the 19-64 years and 65+ years age groups. In these age groups both exceeded the guidance level by 5-fold. This was predominantly from consumption of supplements which may contain up to 500 mg. It is unlikely that these exposures would cause adverse health effects.
Conclusion
44. Chronic exposures of calcium, iron, niacin and thamin from non-wholemeal flour at the current and proposed fortification levels did not exceed the guidance level. For each of the nutrients, the difference in exposure between current and proposed levels of fortification is very small, especially when compared to exposures form the entire diet and from supplements. Therefore, the change to the proposed levels of fortification would not increase the risk to adverse health effects when taken in consideration of the entire diet and consumption of supplements.
45. Intakes of calcium from supplements alone did not exceed the guidance level. Consumption of higher dosage iron, niacin and thamin supplements may result in exceedances of the guidance level. However, it is important to note that not all members of the population will consume supplements.
46. Calcium exposure from food and supplements only exceeded the guidance level EFSA TUL of 2,500 mg/day marginally and only in 97.5th percentile consumers in those aged over 19 years. There is unlikely to be a risk of adverse health effects based on these exposures.
47. Iron exposures from food and supplements exceeded the guidance levels in some age groups, up to a maximum of 2.8-fold the 17 mg/day guidance level. There is unlikely to be a risk of adverse health effects based on these exposures. However, the EVM guidance value does not apply to individuals who have an increased susceptibility to iron overload, a condition which is associated with a homozygous haemochromatosis genotype.
48. In those aged up to 18 years niacin exceedances of the 17 mg/day guidance level (EVM, 2003) were up to 3- and 4.4-fold for mean and 97.5th percentile consumption, respectively. In those aged over 19 years the exceedances of the 17 mg/day guidance level were up to 59- and 65-fold for mean and 97.5th percentile consumers, respectively. Most of this exceedance comes from the consumption of supplements containing niacin at 1,000 mg. Adverse effects from long term exposure to niacin in food would be less likely as free niacin levels in food are low. However, there is some uncertainty because of the data used to establish the EVM guidance level. It is intended for supplements and is more considered for a bolus intake. Exposures from consumption of supplements containing high levels of niacin e.g. 1,000 mg could lead to increased risk of adverse health effects, especially when consumed consistently over a prolonged period of time.
49. Exposures to thiamin for all age groups below 18 years of age are below the guidance level of 100 mg/day (EVM, 2003). Mean and 97.5th percentile intakes from food and supplements only exceeded the guidance level for thiamin in consumers aged over 19, by a maximum of upto 5-fold. This was predominantly from consumption of supplements which may contain up to 500 mg. It is unlikely that these exposures would cause adverse health effects.
50. The NHS states that “most people do not need to take vitamin supplements and can get all the vitamins and minerals they need by eating a healthy, balanced diet”.
51. While the Committee noted that there would be a possible exceedance in individuals that consume supplements, the COT overall concluded that an increase in the minimum fortification level of calcium, iron and niacin to 15% of the NRV would not result in any additional risk when compared to current fortification levels.
