Abstract

The aim of this study was to investigate the effects of dietary sodium nitrite and meat on human health. Sodium nitrite in processed meat is known to be one of the main precursors of carcinogens, such as N-nitroso compounds. However, we previously found that processed meat is not the primary source of sodium nitrite; nitrate or the conversion of nitrate in vegetables are contribute to generate more than 70% Sodium nitrite or nitrate containing compounds in body. Although the heavy consumption of meat is likely to cause various diseases, meat intake is not the only cause of colorectal cancer. Our review indicates that sodium nitrite derived from foods and endogenous nitric oxide may exhibit positive effects on human health, such as preventing cardiovascular disease or improving reproductive function. Therefore, further epidemiological studies considering various factors, such as cigarette consumption, alcohol consumption, stress index, salt intake, and genetic factors, are required to reliably elucidate the effects of dietary sodium nitrite and meat on the incidence of diseases, such as colorectal cancer.

  • The health impact of nitrate intake depends on the food matrix.

    “the health impact of nitrate intake depends on the food matrix”

    From Dietary Nitrate-Rich Vegetables as Natural Modulators of Health: Mechanisms and Benefits in Ageing Populations (2026) · cites this paper as [282]

    The sections on intake through other foods and the physiological action of nitric oxide describe potentially beneficial conversion of dietary nitrate to nitric oxide and potentially harmful nitrosamine formation when nitrite reacts with secondary amines. They also identify different food sources of nitrate, but do not directly establish that nitrate’s health impact depends on the food matrix. (LLM, conf=0.75)

  • Whole plant foods provide protective co-nutrients, whereas processed meats lack these factors and introduce additional risks such as sodium, saturated fat, and haem iron.

    “whole plant foods provide protective co-nutrients, whereas processed meats lack these factors and introduce additional risks such as sodium, saturated fat, and haem iron [281,282,283].”

    From Dietary Nitrate-Rich Vegetables as Natural Modulators of Health: Mechanisms and Benefits in Ageing Populations (2026) · cites this paper as [282]

    The Introduction (page unavailable) links meat heme iron and nitrite added during processing to colorectal-cancer concerns. “Health Benefits of Meat Consumption” (page unavailable) reports that saturated fatty acids in meat and meat products can contribute to cardiovascular disease. The paper does not establish that whole plant foods provide protective co-nutrients or that processed meats lack them, and its sodium discussion concerns sodium nitrite rather than sodium generally.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
