delivered the opinion of the Court.
Thе limited writ of certiorari in this case was granted to review petitioners’ conviction, affirmed by the Circuit Court of Appeals, for a violation of the Filled Milk Act. 1 The Court was moved to allow the petition in order to examine the contentions that the accused articles of food cannot, under the due process clause of the Fifth Amendment to the Constitution, be banned from commerce when these compounds are nutritionally sufficient and not “in imitation оr semblance” of milk or any milk product within the meaning of the statute and are not sold as milk or a milk product.
The contentions which are raised by petitioners to avoid their conviction were not dealt with in our prior decision which upheld the act’s validity upon demurrer to an earlier indictment which charged its violation.
United States
v.
Carolene Products Co.,
The facts, which are undisputed, are fully set out in the opinions of the District Court and the Circuit Court of Appeals. It is sufficient for our purposes to summarize them as follows. The corporate petitioner sells the products mentioned in the indictment which are manufactured for it by another corporation from skim milk, thаt is, milk from which a large percentage of the butterfat has been removed. The process of manufacture consists of taking natural whole milk, extracting the butterfat content and then adding cottonseed or cocoanut oil and fish liver oil, which latter oil contains vitamins A and D. The process includes pasteurization of the milk, evaporation, homogenization of the mixture and sterilization. The compound is sold under various trade names in cans of the sаme size and shape as those used for evaporated milk. *21 The contents of the can are practically indistinguishable by the buying public from evaporated whole milk, but the. cans are truthfully labeled to show the trade names and the ingredients.
The indictment charged the petitioner corporation and the individual petitioners, its president and vice president, with violation of the statute by making interstate shipments of the compounds contrary to § 2. 4 The convictions and sentences are assailed as improper on three grounds: first, that the petitioner’s compounds were not covered by the rationale of the Filled Milk Act; second, that the Act did not cover the compounds because they were not “in imitation or semblance” of a milk product; and third, that since the compounds were wholesome food products and sold without fraud, in any sense, Congress could not constitutionally prohibit their interstate shipment.
First. As a basis for petitioner’s position that the Filled Milk Act does not cover their compounds, it is argued that the nutritional deficiencies of filled milks led to the Act’s enactment so as to protect the public health. These deficiencies occurred because the extraction of the butterfat from the whole milk removed a large proportion of the fat soluble vitamins A and D. The hearings on the bill and the course of the debate make it quite cleаr that this vitamin deficiency was of major importance in bringing about the enactment of the act. 5 Petitioners then offered *22 in the trial court to prove that since the passage of the Filled Milk Act in 1923, the technique of fortification of foods with vitamins A and D had advanced to a point where these vitamins could be restored to skim milk compounds so that the compounds were equally valuable in that respect to whole milk products and that their products had been so enriched. The offer was refused.
Filled milk is defined in § 1 (c) of the act as any milk, “whether or not condensed, evaporated, concentrated, powdered, dried, or desiccated, to which has been added, or which has been blended or compounded with, any fat or oil other than milk fat, so that the resulting product is in imitation or semblance of milk . . ., whether or not condensed, evaporated, concentrated, powdered, dried, or desiccated.” The petitioner’s compounds, it is agreed, fall within this definition. But, petitioners contend, they do not fall within its spirit, since the vitamins which cause deficiency have been restored and that therefore the act is inapplicable to the enriched compounds within that rule of statutory construction, as illustrated by
Church of the Holy Trinity
v.
United States,
Petitioners’ position as to the legislative purpоse of the act was not accepted by the trial or reviewing court. We agree with those courts. While, as we have stated above, the vitamin deficiency was an efficient cause in bringing about the enactment of the Filled Milk Act, it was not the sole reason for its passage. A second reason was that the compounds lend themselves readily to substitution
*23
for or confusion with milk products. Although, so far as the record shows, filled milk compounds as enriched arе equally wholesome and nutritious as milk with the same content of calories and vitamins, they are artificial or manufactured foods which are cheaper to produce than similar whole milk products. When compounded and canned, whether enriched or not, they are indistinguishable by the ordinary consumer from processed natural milk. The purchaser of these compounds does not get evaporated milk. This situation has not changed since the enactment of the act. The possibility and actuality of confusion, deception and substitution was appraised by Congress.

The prevention of such practices or dangers through control of shipments in interstate commerce is within the power of Congress.
United States
v.
Carotene Products Co.,
Second.
The petitioners urge another reason why the act does not cover their compounds. This ground is that the compounds are not “in imitation or semblance” of-milk within the meaning of the act’s definition of filled milk. § 1 (c),
supra,
p. 22. Compare
State
v.
Carotene Products Co.,
Petitioners rely upon the admitted fact that no ingredient is added to the skim milk, oil and vitamins to alter the appearance of the compound. Accepting the evidence that the compounds are indistinguishable from whole milk products by purchasers, it is urged that they cannot be held to be in “imitation or semblance” of milk unless the manufacturer purposefully adds something to make the mixture simulate milk. It is said Congress adopted this language from § 64 (3) of the Farms and Markets Law of New York.

Prior to that time, the Court of Appeals of New York, in construing the words “imitation or semblance” as they appeared in another section of the New York law directed at the regulation of oleomargarine, had interpreted them as denouncing trade in oleomargarine only when the manufacturer consciously and purposefully attempted to create an imitation or semblance of milk products.
People
v.
Guiton,
210 N. Y.
*26
1, 8, 9,
The cases just cited have established under suitable conditions the rule for which petitioners contend that the interpretation goes with the act. It is a presumption of legislative intention, however, which varies in strength with the similarity of the language, the established character of the decisions in the jurisdiction from which the language was adopted and the presence оr lack of other indicia of intention.
Copper Queen Mining Co.
v.
Arizona Board,
Here we cannot be sure that Congress, deliberately or otherwise, adopted the wording from the New York statute. In § 2 of the federal act of August 2, 1886, 24 Stat. 209, taxing and regulating oleomargarine, somewhat similar language occurs.
11
That may be the source of the
*27
phrase. Furthermore the
Guiton
ease did not interpret the section of the New York statute upon which petitioners contend the federal act is modeled. In the
Guiton
case, the Court of Appeals explained the force of “imitation and semblance” as used in the oleomargarine section, § 38, N. Y. Laws 1909, ch. 9. That court relied upon the special statutory definition of oleomargarine in § 30,
id.,
as a reason for its conclusion that the words prohibited only conscious imitation,
Finally, as determinative of the intention of Congress to include compounds whose resemblance to milk products arises from their ingredients and not from conscious effort, we note the fact that compounds of this innocent character were specifically included by name in the list of compounds which the Congressional reports pointed out as products which were covered by the proposed act. 12 Petitioner’s compounds were themselves so named. The addition of vitamins does not affect their physical likeness to milk products.
Third.
If the Filled Milk Act is applicable to the compounds whose shipment was the basis of thе indictment in this case, as we have just concluded, petitioners assert
*28
that the act, as thus applied, violates the due process clause of the Fifth Amendment. Their argument runs in this manner. Since these enriched compounds are admittedly wholesome and sold under trade names with proper labels without the commission of any fraud by petitioners on the public, Congress cannot prohibit their interstate shipment without denying to petitioners a right protected by the due process clause, the right to trade in innocent articles. They rely upon
Weaver
v.
Palmer Bros. Co.,
We do not need to consider the refusal of the trial court to receive evidence of the purity and wholesomeness of petitioner’s products. Such evidence could be material only if the sole basis for Congressional action was impurity and unwholesomeness. 13 Under the first point of this opinion, we have determined that the avoidance of confusion furnished a reason for the enactment of the Filled Milk Act. The trial court took judicial notice, as did the District Court of the District of Columbia, United States v. Carolene Products Co., 51 F. Supp. 675, 678-79, and as we do, of the reports of the committees of the House of Representatives and the Senate which show that other considerations than nutritional deficiencies influenced the prohibition of the shipment of filled milk in interstate commerce. These unchallenged reports, as we indicated *29 in part “First” above, furnish an adequate basis, other than unwholesomeness, for the action of Congress. 14 The reports show that it was disputable as to whether wholesome filled milk should be excluded from commerce because of the danger of its confusion with the condensed or evaporated natural product or whether regulation would be sufficient. The power was in Congress to decide its own course. We need look no further. 15
Weaver
v.
Palmer Bros. Co., supra,
is not to- the contrary. This Court thought that under the facts of that record there was no reasonable basis for the legislative determination that the use of shoddy in comfortables was dangerous to the public health or that it offered opportunity for deception, pp. 412 and 414. Therefore the prohibition of its use violated the due process clause оf the Fourteenth Amendment. Sterilization, inspection and labeling were deemed to be sufficient to negative the possibility of such evils. It was pointed out in the course of the opinion, p. 413, that where the possibility of evil was not negatived, legislation prohibiting the sale of a wholesome article would not be invalidated.
Powell
v.
Pennsylvania,
“The defendant then offered to prove by Prof. Hugo Blanck that he saw manufactured the article sold to the prosecuting witness; that it was made from pure animal fats; that the process of manufacture was clean and wholesome, the article containing the same elements' as dairy butter, . . . that the oleaginous substances in the manufactured article were substantially identical with those produced from milk or cream; and that the article sold to the prosecuting witness was a wholesome and nutritious article of food, in all respects as wholesome as butter produced from pure unadulterated milk or cream from unadulterated milk.” Pp. 681-82.
“It will be observed that the offer in the court below was to show by proof that the particular articles the defendant sold, and those in his possession for sale, in violation of the statute, were, in fact, wholesome or nutritious articles of food. It is entirely consistent with that offer that many, indeed, that most kinds of oleomargarine butter in the market contain ingredients that are or may become injurious to health. The court cannot say, from anything of which it may take judicial cognizance, that such is not the fact.....
“Whether the manufacture of oleomargarine, or imitation butter, of the kind described in the statute, is, or may be, conducted in such a way, or with such skill and secrecy, as to baffle ordinary inspection, or whether it involves such danger to the public health as to require, for the protection of the people, the entire suppression of the business, rather than its regulation in such manner as to permit the manufacture and sale of articles of that class *31 that do not contain noxious ingredients, are questions of fact and of public policy which belong to the legislative department to determine. And as it does not appear upon the face of the statute, or from any facts of which the court must take judicial cognizance, that it infringes rights secured by the fundamental law, the legislative determination of those questions is conclusive upon the courts.” Pp. 684-85.
In
Hebe Co.
v.
Shaw,
In the action of Congress on filled milk there is no prohibition of the shipment of an article of commerce merely because it competes with another such article which it resembles. Such would be the prohibition of the shipment of cotton or silk textiles to protect rayon or nylon or of anthracite to aid the consumption of bituminous coal or of cottonseed oil to aid the soybean industry. Here a milk product, skimmed milk, from which a valuable element — butterfat—has been removed is artificially enriched with cheaper fats and vitamins so that it is indistinguishable in the eyes of the average purchaser from whole milk products. The result is that the compound is confused with and passed off as the whole milk product in spite of proper labeling.
When Congress exercises a delegated power such as that over interstate commerce, the methods which it employs to carry out its purposes are beyond attack without a clear and convincing showing that there is no rational basis for *32 the legislation; that it is an arbitrary fiat. 16 This is not shown here. The judgment is
Affirmed.

The manufacturers can not sell it as milk, but it is put up in the same size cans as regular condensed milk, and the evidence before the committee shows that it is advertised by the retail dealers as milk and evaporated milk. Storekeepers sell it with the statements that ‘it takes the place of milk/ ‘just as good as condensed and much cheaper/ ‘nothing better on the market/ ‘takes the place of condensed milk.’ Instances have been found in which the coconut fat was mixed with milk and sold for cream; the compound has been used for making ice cream. ... In many cases retailers sell the compound for the same price as the straight evaporated milk, although the price per 1-pound can to them is about 3 cents less. A number of surveys in various parts of the country show that the compound is sold largely in sections inhabited by people unable to read English and sections inhabited by people of limited means, and not sold at all in better residеntial districts.” Cf, also S.
