Sec.  101.74  Health claims: sodium and hypertension.

    (a) Relationship between sodium and hypertension (high blood 
pressure). (1) Hypertension, or high blood pressure, generally means a 
systolic blood pressure of greater than 140 millimeters of mercury (mm 
Hg) or a diastolic blood pressure of greater than 90 mm Hg. 
Normotension, or normal blood pressure, is a systolic blood pressure 
below 140 mm Hg and diastolic blood pressure below 90 mm Hg. Sodium is 
specified here as the chemical entity or electrolyte ``sodium'' and is 
distinguished from sodium chloride, or salt, which is 39 percent sodium 
by weight.
    (2) The scientific evidence establishes that diets high in sodium 
are associated with a high prevalence of hypertension or high blood 
pressure and with increases in blood pressure with age, and that diets 
low in sodium are associated with a low prevalence of hypertension or 
high blood pressure and with a low or no increase of blood pressure with 
age.
    (b) Significance of sodium in relation to high blood pressure. (1) 
High blood pressure is a public health concern primarily because it is a 
major risk factor for mortality from coronary heart disease and stroke. 
Early management of high blood pressure is a major public health goal 
that can assist in reducing mortality associated with coronary heart 
disease and stroke. There is a continuum of mortality risk that 
increases as blood pressures rise. Individuals with high blood pressure 
are at greatest risk, and individuals with moderately high, high normal, 
and normal blood pressure are at steadily decreasing risk. The 
scientific evidence indicates that reducing sodium intake lowers blood 
pressure and associated risks in many but not all hypertensive 
individuals. There is also evidence that reducing sodium intake lowers 
blood pressure and associated risks in many but not all normotensive 
individuals as well.
    (2) The populations at greatest risk for high blood pressure, and 
those most likely to benefit from sodium reduction, include those with 
family histories of high blood pressure, the elderly, males because they 
develop hypertension earlier in life than females, and black males and 
females. Although some population groups are at greater risk than 
others, high blood-pressure is a disease of public health concern for 
all population groups. Sodium intake, alcohol consumption, and obesity 
are identified risk factors for high blood pressure.
    (3) Sodium intakes exceed recommended levels in almost every group 
in the United States. One of the major public health recommendations 
relative to high blood pressure is to decrease consumption of salt. On a 
population-wide basis, reducing the average sodium intake would have a 
small but significant effect on reducing the average blood pressure, 
and, consequently, reducing mortality from coronary heart disease and 
stroke.
    (4) Sodium is an essential nutrient, and experts have recommended a 
safe minimum level of 500 milligrams (mg) sodium per day and an upper 
level of 2,400 mg sodium per day, the FDA Daily Value for sodium.
    (c) Requirements. (1) All requirements set forth in Sec.  101.14 
shall be met.
    (2) Specific requirements--(i) Nature of the claim. A health claim 
associating diets low in sodium with reduced risk of high blood pressure 
may be made on the label or labeling of a food described in paragraph 
(c)(2)(ii) of this section, provided that:
    (A) The claim states that diets low in sodium ``may'' or ``might'' 
reduce the risk of high blood pressure;
    (B) In specifying the disease, the claim uses the term ``high blood 
pressure'';
    (C) In specifying the nutrient, the claim uses the term ``sodium'';
    (D) The claim does not attribute any degree of reduction in risk of 
high blood pressure to diets low in sodium; and
    (E) The claim indicates that development of high blood pressure 
depends on many factors.

    (ii) Nature of the food. The food shall meet all of the nutrient 
content requirements of Sec.  101.61 for a ``low sodium'' food.
    (d) Optional information. (1) The claim may identify one or more of 
the following risk factors for development of high blood pressure in 
addition to dietary sodium consumption: Family history of high blood 
pressure, growing older, alcohol consumption, and excess weight.
    (2) The claim may include information from paragraphs (a) and (b) of 
this section, which summarizes the relationship between dietary sodium 
and high blood pressure and the significance of the relationship.
    (3) The claim may include information on the number of people in the 
United States who have high blood pressure. The sources of this 
information must be identified, and it must be current information from 
the National Center for Health Statistics, the National Institutes of 
Health, or ``Nutrition and Your Health: Dietary Guidelines for 
Americans,'' U.S. Department of Health and Human Services (DHHS) and 
U.S. Department of Argiculture (USDA), Government Printing Office.
    (4) The claim may indicate that it is consistent with ``Nutrition 
and Your Health: U.S. Dietary Guidelines for Americans, DHHS and USDA, 
Government Printing Office.
    (5) In specifying the nutrient, the claim may include the term 
``salt'' in addition to the term ``sodium.''
    (6) In specifying the disease, the claim may include the term 
``hypertension'' in addition to the term ``high blood pressure.''
    (7) The claim may state that individuals with high blood pressure 
should consult their physicians for medical advice and treatment. If the 
claim defines high or normal blood pressure, then the health claim must 
state that individuals with high blood pressure should consult their 
physicians for medical advice and treatment.
    (e) Model health claims. The following are model health claims that 
may be used in food labeling to describe the relationship between 
dietary sodium and high blood pressure:
    (1) Diets low in sodium may reduce the risk of high blood pressure, 
a disease associated with many factors.
    (2) Development of hypertension or high blood pressure depends on 
many factors. [This product] can be part of a low sodium, low salt diet 
that might reduce the risk of hypertension or high blood pressure.
