Description

COMPOSITION AND TREATMENT FOR PERSISTENT REPRODUCTIVE TRANSITION SYMPTOMS

1. Field of the Invention The present invention relates to compositions and methods for alleviating ailments symptomatic of premenopausal and/or menopausal disorders, associated in some way with an acute, temporary, developing, or chronic imbalance in the serum levels of endogenous, gynecologically relevant substances, including certain neurotransmitters, neurotransmitter substrates and/or hormones. In particular, the present invention relates to a composition or compositions comprising a mixture of remedial carbohydrates and at least one phytoestrogen, which on administration to a subject in need thereof relieves or manages the disorders, manifestations, conditions, or discomforts complained of.

2. Background of the Invention Somatic, emotional, metabolic and cognitive difficulties, including sleep problems, vasomotor symptoms and mood swings, are just some of the symptoms experienced by many menopausal women and also by many premenopausal or perimenopausal women. The severity of the symptoms caused by these reproductive physiological changes may differ among women of various ages (and even within women of approximately the same age) . Some women have little or no discomfort, while others become socially and/or physically dysfunctional. As for women undergoing menopause, fully 58 percent describe the process as "somewhat bothersome", while a third to one fifth of women found it "very bothersome" depending upon the age of the women reaching menopause . Prevention, (Aug. 1994) 78-142. The collection of such various aches, irritability, water retention and other complaints experienced to some degree or another by these women whose bodies are in a state of flux can be generally referred to as Symptoms of Persistent Reproductive Transition or SPRT.

The etiology of these reproductive physiological changes is not universally agreed upon. SPRT-related changes can affect vasomotor, cognitive, psychological and sexual functions. Specific symptoms include, but are not limited to, weight gain, sleep disorders, hot flashes, sweating, nervousness, depression, anxiety, vertigo, fatigue, arthralgia, headache, tachycardia, vaginal dryness and heavy bleeding.

It is believed that altered estrogen levels in women may play a significant role in causing SPRT-related ailments. Consequently, Hormonal Replacement Therapy

(HRT) has been prescribed as a means to supplement or replace the loss of estrogen commonly observed in women experiencing SPRT-related ailments. The estrogen and endogenous hormones used in HRT, however, have undesirable side effects such as weight gain, excessive bleeding, fluid retention, and increased risk of cancer. See, Prevention, (Aug. 1994) 78-142. Safer and more effective therapies for SPRT-related ailments continue to be sought .

There are a number of articles describing the potential treatment of the somatic symptoms of menopausal women by ingestion of foods enriched with phytoestrogens or by ingestion of concentrated forms of phytoestrogens. It has been recognized that the incidence of certain somatic symptoms occurs less frequently in Chinese and Japanese women as compared to women in western countries. Substantial dietary differences exist between these Eastern and Western populations, especially related to the consumption of soy products. Consequently, it has been suggested that the estrogenic effects of phytoestrogens found in soy foods may be responsible for modifying the frequency and severity of somatic symptoms observed in menopausal women in different countries. See, Knight, D. C. et al . , Obstetrics & Gynecology, (1996) 87:897-904.

Phytoestrogens are naturally occurring compounds found in many foods and are defined as plant substances that are structurally or functionally similar to estradiol and consist of a number of classes, including lignans, isoflavones, coumestans and resorcylic acid lignans. Recently, a few reports have appeared purporting to observe the alleviation of some somatic symptoms of menopausal women based on the use of the isoflavonoid class of phytoestrogens . These reports , however, continue to focus solely on the use of isoflavonoids as potential agents for modifying estrogen levels to treat somatic symptoms. Most significantly, these references do not teach, disclose, or suggest any benefits to emotional, cognitive, or metabolic symptoms. Nor do these references teach, disclose, or suggest any benefits to the administration or co-administration of remedial carbohydrates to provide relief to a whole host of SPRT- related ailments.

Descriptions of methods for treating somatic symptoms of menopausal women by the administration of phytoestrogens exist. Gorbach et al . , in U.S. Patent No. 5,498,631, describe a method of treating premenstrual symptoms, menopausal symptoms, or a condition related to reduced levels of endogenous estrogen in women by administering isoflavonoids, which are thought to substitute for the reduced levels of endogenous estrogen. Clearly, Gorbach et al . concentrate on the alleged estrogen-like actions of isoflavonoids . Gorbach et al . make no mention of the potential role of isoflavonoids in a composition or treatment, which also includes effective amounts of remedial carbohydrates, to alleviate a broader range of SPRT-related ailments, including those having an etiology in reduced levels of serotonin. Furthermore, Gorbach et al . do not mention the potential role of phytoestrogens for the treatment of emotional, metabolic, or cognitive disorders.

In U.S . Patent No. 5,506,211 issued to Barnes et al . , methods are disclosed for treating patients specifically with the isoflavone genistein to inhibit osteoclastic activity, thereby allegedly preventing osteoporosis. Similarly, Shlyankevich, in U.S. Patent No. 5,424,331, concentrates on the use of phytoestrogens as a means for regulating hormonal levels in women suffering form osteoporosis. Furthermore, Hughes et al . , in U.S. Patent No. 5,516,528, describe a composition comprising mammalian estrogen as a means for regulating hormonal imbalances. Neither Shlyankevich nor Hughes et al . disclose a method for alleviating common SPRT-related ailments. Apart from attempting to treat solely the somatic symptoms related to reproductive physiological changes, other references have utilized chemically modified isoflavones, also referred to herein as phytoestrogen derivatives. In U.S. Patent No. 4,390,559, granted to Zilliken, a composition is described using a chemically modified isoflavonoid-like compounds as antioxidants for the preservation of fats and oils. These methods and compositions do not use the naturally occurring isoflavone. Moreover, the use of excessive amounts of fats and oils would inhibit the beneficial effects of remedial carbohydrates. Similarly, U.S. Patent No.

5,352,384, granted to Shen, describes a modified isoflavone that is combined with a highly insoluble fiber.

In U.S. Patent 4,557,927, granted to Miyake et al . , a process is disclosed for enzymatically converting natural soybean glycosides to an alpha-glycosylated product in which the carbohydrate enzyme substrate is covalently bonded to the phytoestrogen. Similarly, isoflavonoid compounds can be synthesized which resemble the natural isoflavones. In Patent Nos . 4,166,862, 4,163,746, 3,949,085 and 3,864,362, granted to Feuer et al., non-natural isoflavone compounds are synthesized for use as anabolic or catabolic feed additives. Stadler nee Szoke et al . , in U.S. Patent Nos. 5, 043 , 326 and 4, 826, 963, describe a method for the preparation of inclusion complexes of ipriflavon cyclodextrin.

Despite a great deal of effort in developing treatments for menopause, there remains an unfulfilled need for a more effective, comprehensive therapy. In particular, prior compositions for treating menopause have involved the use of hormonal replacement therapy, which fall well short of addressing the needs of those women experiencing SPRT-related ailments. Quite surprisingly, it has now been found that a more general sense of well- being, as well as other benefits, is observed through a regimen that affects the imbalances in the body, which imbalances are due not only to hormone or hormone-like substances but also to other substances of gynecological significance, including classes of neurotransmitters .

In mammals, the amino acid tryptophan is the precursor to serotonin synthesis in the brain. Certain carbohydrates, when ingested, can increase the ratio of tryptophan to large neutral amino acids (T:LNAA) in the blood stream. An increase in the ratio of T:LNAA has been shown to result in a higher level of tryptophan in the brain. A higher level of tryptophan in the brain is believed, in turn, to lead to an increase in the synthesis of endogenous serotonin. While conventional foods (e.g., a potato or a bagel) may fortuitously shift the T:LNAA ratio to a limited extent, these conventional foods also contain fats, sources of protein, other fibers, or may be consumed with other foods that serve as sources of these other components. These other components of conventional foods may slow down digestion, absorption, metabolism and excretion, increase the levels of large neutral amino acids, or otherwise interfere with the desired shift in the balance of specific amino acids in the blood. It is also important to point out that while a deficiency or imbalance in serotonin levels has emerged as a leading theory behind the symptoms of premenstrual syndrome or PMS (e.g. , a number of studies have shown that women with PMS may have a lower serotonin level than women without PMS) , such a theory fails to account for or predict the effect of the regulation of serotonin levels

(or the levels of other select neurotransmitters, such as dopamine) on premenopausal or menopausal women. The present invention relates to the discovery that a composition comprising an effective amount of at least one phytoestrogen, in conjunction with a mixture or blend of remedial carbohydrates or in conjunction with choline or a source of choline, can alleviate, treat, or prevent SPRT-related ailments.

3. Summary of the Invention

The present invention is directed generally to compositions exhibiting surprising efficacy in alleviating conditions and/or disorders of the type that women experiencing symptoms of persistent reproductive transition (SPRT) complain of. The present invention is also directed to methods of treating, preventing, inhibiting, managing, ameliorating, or alleviating such symptoms. In particular, relief from the negative effects of the symptoms or manifestations, including somatic, emotional, metabolic, or cognitive disorders, may be achieved through dietary management using the compositions and methods of the invention. Accordingly, the invention provides a composition for alleviating symptoms of persistent reproductive transition

(SPRT) comprising (i) a first active ingredient comprising at least one phytoestrogen, a source of at least one phytoestrogen, or combinations thereof and (ii) a second active ingredient comprising (a) a mixture of remedial carbohydrates including at least one simple remedial carbohydrate, at least one complex remedial carbohydrate and at least a starch, (b) choline, a source of choline, or combinations thereof, or (c) both (a) and (b) , the composition being substantially free of added beta- sitosterol if the second active ingredient comprises phosphatidyl choline. In other embodiments, however, particularly those in which the second active ingredient does not comprise phosphatidyl choline, phytosterols may be added to advantage. The invention also provides a method of alleviating the negative effects of symptoms of persistent reproductive transition (SPRT) comprising administering to a subject in need thereof an effective amount of at least a first substance comprising at least one phytoestrogen, a source of at least one phytoestrogen, or combinations thereof and an effective amount of at least a second substance comprising (a) a mixture of remedial carbohydrates including at least one simple remedial carbohydrate, at least one complex remedial carbohydrate and at least one remedial starch, (b) choline, a source of choline, or combinations thereof, or (c) a combination of (a) and (b) . Consistent with a method of dietary management, first, second, or both substances are preferably administered with a carrier, more preferably a nutritionally acceptable carrier, most preferably an edible solid, edible semi-solid, or edible liquid carrier.

The invention also contemplates a method that alleviates the negative effects of symptoms of persistent reproductive transition (SPRT) relating to emotional disorders, metabolic disorders, cognitive disorders, or combinations thereof, but not somatic disorders, comprising administering to the subject in need thereof an effective amount of at least one phytoestrogen, a source of at least one phytoestrogen, or combinations thereof. In a particular embodiment, the method contemplated further comprises administering an effective amount of a blend of two or more remedial carbohydrates, preferably a mixture of at least one simple remedial carbohydrate, at least one complex remedial carbohydrate and at least one remedial starch. More preferably, the method further comprises administering an effective amount of choline or a source thereof. Any route of administration can be taken. However, the oral (by mouth) or topical (transdermally, intravaginally, or the like) route is preferred. Moreover, each active component can be administered sequentially, preferably within about an hour of each other, or substantially concurrently.

It has surprisingly been discovered that the compositions and methods of the invention provide great benefits to women who experience a whole range of discomforts associated with SPRT. Such benefits include relief from, for example, somatic, emotional, metabolic, or cognitive associated ailments. It is believed that the compositions and methods of the invention provide relief from the symptoms by supplying particular nutrients, including a combination of selected substances, having the capacity to correct (through a regimen of dietary management) adverse physiological, psychological and psychiatric states stemming from alterations primarily in endocrine synthesis and secretion accompanying a woman's approach, progression and passage through a post reproductive stage during her later years of life.

To name some of the specific benefits observed from the administration of the compositions or implementation of the methods of the invention to subjects suffering from SPRT-related ailments include, but are not limited to, inhibition of breakthrough bleeding, elimination of need for concurrent hormone replacement therapy, stimulation of osteoblastic activity and inhibition of the hardening of the vasculature . In other instances, it has also been observed that subjects receiving treatment experience an improvement in mood, less water retention, less irritability, or an increased ability to concentrate or remain mentally alert.

Hence, in a specific embodiment of the invention, a useful composition is disclosed for the dietary management of SPRT-related ailments, comprising at least one phytoestrogen, a source of at least one phytoestrogen, or combinations thereof and a mixture of blend of remedial carbohydrates. In another embodiment, the composition of the invention further comprises an amount of choline sufficient to inhibit or reverse episodes of cognitive deficit or decline, including lack of alertness or an inability to maintain premenopausal functionality, in those females unsettled by symptoms of persistent reproductive transition. In still another embodiment, a composition is described which comprises a combination of at least one phytoestrogen, a source of at least one phytoestrogen, or combinations thereof and an effective amount of choline, a source of choline, or combinations thereof, independent of the presence of an effective amount of a mixture or blend of selected remedial carbohydrates.

Hence, the invention contemplates methods of using therapeutic and/or nutritional compositions for alleviating, treating, preventing, ameliorating, or managing the adverse effects of SPRT-related ailments. Broadly, such methods comprise administering a therapeutically or nutritionally effective amount of the composition to subjects in need thereof.

Other objects of the invention will become apparent to those of ordinary skill in the art upon further consideration of the entire disclosure provided herewith.

4. Glossary of Terms

The following terms appear in the present specification and are defined as follows: Symptoms of Persistent Reproductive Transition or SPRT - A collection of symptoms, manifestations, disorders, complaints, discomforts, or aches and pains which is experienced by perimenopausal or premenopausal women, menopausal women, or postmenopausal women. In particular, a subject suffering from SPRT or an SPRT- related ailment is a woman having at least one, preferably at least two, most preferably at least three of the symptoms listed in Table 1, below, which symptoms are categorized as somatic, emotional, metabolic, cognitive, or nighttime symptoms.

TABLE 1. ILLUSTRATIVE DISORDERS/SYMPTOMS/MANIFESTATIONS ASSOCIATED WITH SPRT

I . Somatic vaginal dryness hot flashes fluid retention breakthrough bleeding excessive bleeding vertigo headache or migraines tachycardia libido changes (loss of sexual drive) sleep problems joint pain frequent urination (incontinence) breast tenderness chills cold sweats (night sweats)

II. Emotional irritability anxiety lack of energy (lethargic) fatigue mood changes (depressed mood, mood swings)

III. Metabolic weight gain marked change in appetite (increased or decreased) arthralgia (muscle ache) carbohydrate craving greater tendency to incur a bone fracture IV. Cognitive forget fulness recall or short term memory loss loss of alertness inability to concentrate

V. Nighttime or Sleep Related Symptoms vaginal dryness libido change sleep problems chills incontinence (bladder control) night sweats

The sub-category of sleep problems may relate to difficulty in initially falling asleep, waking up one or more times during the night, difficulty in falling back asleep once awakening during the night, lack of quality sleep (e.g., a fitful sleep), a feeling of grogginess in the morning, and the like.

Another subject in need of treatment, who may benefit from the invention, is a woman having episodic or chronic manifestations of at least two of the recited SPRT-related conditions (ailments, disorders and the like) and who is also experiencing changes or irregularities in her menstrual flow or cycle attributable to perimenopausal, menopausal, or postmenopausal transition. It is important to note, however, that some of the same symptoms, which are listed in Table 1, can be induced through the administration of, intake of, or exposure to pharmacological agents, chemicals, hormones and the like, or through accident, trauma, or surgery (e.g., loss or removal of some portion of the reproductive system, such as the uterus and/or one or both ovaries) .

Remedial carbohydrates - Simple or complex carbohydrates, including certain forms of starch, which are rapidly digestible and which on consumption increases serotonin levels in the blood, serum, plasma, or synaptic structure (s) relative to the levels of this substance in the blood, serum, plasma, or synaptic structure (s) prior to the consumption of the remedial carbohydrate. That is, consumption of these remedial carbohydrates increases the level of endogenous serotonin synthesis . Examples of such remedial carbohydrates include, but are not limited to, dextrose, galactose, mannose, dextrin, maltodextrin, cyclodextrin, potato starch, pre-gelatinized starch, gelatinized starch, fructose, sucrose, maltose, maltotriose, maltotetraose, or mixtures thereof. It should be pointed out that the remedial carbohydrates, which are suitable for use in the invention, are substances, naturally derived or otherwise, which are deliberately added (as an admixture) to the other components of the compositions of the present invention. That is, carbohydrates, such as conventional flour, that may be naturally present in certain foodstuffs are not considered to be remedial carbohydrates. In addition, a mixture or blend of two or more, perhaps three or more, remedial carbohydrates refers to a physical combination or admixture of two, three, or more distinct types of remedial carbohydrates. In preferred embodiments of the invention, a mixture comprising at least one simple remedial carbohydrate, at least one complex remedial carbohydrate and at least one remedial starch may be utilized.

Phytoestrogens - Substances that belong to a family of compounds that are naturally found in certain plants (a natural source), including foodstuffs, especially soy and soy products. Soy proteins are a convenient source of phytoestrogens, especially soy phytoestrogens. Examples of phytoestrogen compounds include, but are not limited to, lignan, genistein, daidzein, Biochanin A, formononetin, O-desmethylangolensin, glycetein, texasin, equol, prunetin, apegenin, coumestrol, saponaretin, 7- hydroxyisoflavone, 5 , 7-dihydroxyisoflavone , 7,4- dihydroxyflavone, 6 , 7 , 4 ' -trihydroxyisoflavone, or their natural glycosylated (e.g., genistein 7-D-glucoside) , acetylated, or methoxylated (e.g., genistein 4 '-methyl ether) forms . Phytoestrogens can occur and be used either as the aglycon (i.e., minus the sugar moiety), ester, ether, or as the glycosylated form (i.e., glycosides) . Examples, of phytoestrogen glycosides include, but are not limited to, genistin, daidzin, glycetin, saponarin and the like. Naturally obtained phytoestrogens can, of course, be prepared synthetically or semi-synthetically using conventional synthetic methods. In keeping with the desire to substantially utilize only naturally occurring active components, phytoestrogens, as used herein, do not include synthetic derivatives or analogs of the naturally obtained phytoestrogens, except as mentioned above. Such derivatives or analogs of phytoestrogens may also be referred to herein simply as "phytoestrogen derivatives." Choline or a Source of Choline - These terms refer to the substance choline or 2-hydroxy-N, N,N- trimethylethanaminium [HOCH₂CH₂N⁺ (CH₃) ₃] , to choline salts, typically as its halide (e.g., fluoride, chloride, bromide or iodide) or hydroxide salt, or to a substance, which when broken down in the body increases circulating levels of choline. Examples of substances that provides a source of choline in vivo, include but are not limited to citicoline or CDP-choline, phosphatidyl choline and the like. Certain foods or foodstuffs may also provide a source of choline, including but not limited to, animal and plant products, such as bile, brains, lecithin and the like, egg yolks, hops, barley, belladonna, or strophanthus .

Phytosterols - Substances having a steroidal backbone or nucleus and which may be isolated from plants. An example, includes alpha-sitosterol , beta-sitosterol , gamma-sitosterol , campesterol, stigmasterol , delta-5- avennasterol , delta-7-stigmasterol , brassicasterol , lupenol , alpha-spinasterol , or the like. Phytosterols may be present naturally in certain foods and foodstuffs, which may form part of the compositions of the present invention. Phytosterols may also be deliberately added, except as noted above concerning the proviso against a combination of beta-sitosterol and phosphatidyl choline.

5. Detailed Description of the Preferred Embodiments One of the principal ingredients of the instant compositions, phytoestrogens, is generally available as isoflavones and can be obtained from soy proteins, soybeans, vegetable protein, tempeh, tofu, miso, aburage, atuage, or koridofu. Preferred phytoestrogens include, but are not limited to, genistein, daidzein, glycetin or a combination thereof. As mentioned above, the remedial carbohydrate mixture or blend constitutes an admixture of two or more, preferably three or more, different types of remedial carbohydrates. Preferred types of remedial carbohydrates include, but are not limited to, dextrose, dextrin, maltodextrin, mannose, pre-gelatinized starch, gelatinized starch and starch, particularly potato starch. Choline or a source thereof can be obtained from any combination of lecithin, choline chloride, choline bitartrate and choline dihydrocitrate . Choline, itself, comprises free choline, its salt, ester, acid, or synthetic or natural conjugate (e.g., CDP-choline, phosphatidyl choline and the like) .

In one embodiment of the invention compositions are provided which comprise at least one phytoestrogen in an admixture with at least a second active component selected from (i) a mixture or blend of remedial carbohydrates, (ii) choline or a source thereof, or (iii) both carbohydrates and choline. A, preferred composition comprises an admixture of (a) about 20-100 g of soy protein (preferably, about 20-80 g or more preferably, about 30-60 g) comprising about 20-55 mg, preferably about 30-45 mg, of soy isoflavones (i.e., one or more phytoestrogens) , (b) about 20-80 g of the remedial carbohydrate mixture or blend comprising about 25-45% of dextrose, about 40-70% of maltodextrin and about 1-10% of potato starch by weight of total remedial carbohydrate, and (c) about 0-5 g of choline, preferably about 1-3 g. A more preferred composition comprises an admixture of (a) about 60 g of soy protein comprising at least about 14 to about 27 mg of genistein and at least about 12 to about 18 mg of daidzein, (b) about 50 g of a remedial carbohydrate mix comprising about 37% of dextrose, about 60% of maltodextrin and about 3% of potato starch by weight of total remedial carbohydrate, and (c) about 1 g of free choline. As discussed above, the genistein and daidzein can be replaced by genistin and daidzin, either individually or together.

Preferably, the compositions provided are combined with a carrier, more preferably a nutritionally acceptable carrier, such as an edible solid, semi-solid, or liquid carrier, including in the form of dietary product, food, food snacks, or drink, to name a few. Preferred carriers may include sorbet, sherbet, apple sauce, or pudding. Hence, the compositions contemplated can come in many forms including, but not limited to, a dry powder, liquid concentrate, ready-to-drink, ready-to-eat , cold, ambient, hot, beverage or prepared food, e.g., a flavored drink or breakfast cereal, cereal additive (sprinkled on), pastry or baked goods (pop tart, cookie, biscuit, cracker, coffee cake, muffin), pudding or food bar, frozen product (pop tart, ice cream), cake mix, or spread.

Another embodiment of the invention is directed to a method for managing, treating, alleviating, or preventing emotional, metabolic, or cognitive disorders experienced by premenopausal, menopausal, or postmenopausal women by administering to the subject an effective amount of at least one phytoestrogen. Preferable, the subject in need of such treatment is administered about 30-60 g of soy protein, which includes about 30-45 mg of isoflavones. Most preferably, the subject is administered about 60 g of soy protein which includes about 27 mg of genistein and about 18 mg of daidzein.

When the composition or method of the invention calls for the presence of remedial carbohydrates, simple carbohydrates may be selected from dextrose, galactose, mannose, fructose, sucrose, maltose, or mixtures thereof, while complex remedial carbohydrate may be selected from dextrin, maltodextrin, cyclodextrin, maltotriose, maltotetraose, or mixtures thereof. The remedial starch may be in turn selected from potato starch, pre- gelatinized starch, gelatinized starch, or mixtures thereof .

The subject in need of such treatment is administered the therapeutic, dietary, or nutritional composition once or twice a day, preferably in the morning and/or evening. If the composition is administered more than once a day, the administrations are preferably separated by about four to about fourteen hours, preferably, about six to about twelve hours, more preferably about eight to about ten hours. The regimen may last for only a day, a few days, or it may continue for as long as the symptoms persist

(e.g., daily for 365 days of the year) . More typically, however, the regimen may last anywhere from a period of about one week, two weeks, three weeks, or four weeks to a period of about one month, two months, three months, four months, five months, six months, or at least a year.

In yet another embodiment of the invention, a method is described for managing, treating, alleviating, or preventing in a subject suffering from a SPRT-related condition, which method comprises administering to the subject in need thereof an effective amount of at least one phytoestrogen and at least a second component selected from (i) a mixture or blend of remedial carbohydrates or (ii) choline or source thereof. A preferred method comprises administering to the subject an admixture of (a) about 100 g of soy protein comprising at least about 50 mg of genistin and about 30 mg of daidzin, (b) about 50 g of a remedial carbohydrate mix comprising about 35-40% of dextrose, about 50-60% of maltodextrin and about 1-5% of potato starch by weight of total remedial carbohydrate, and (c) about 1-2 g of a choline salt.

The ultimate amount of phytoestrogen, carbohydrates, and/or choline administered will ultimately vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the age, health and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; and the effect desired.

As stated above, the therapeutic compositions can be prepared in the form of a ready-to-use dietary product or in the form of a dietary product concentrate. Ready-to- use products include, but are not limited to, prepared foods such as a beverage, pastry, baked goods, pudding, food bar, or frozen product. Concentrated forms include, but are not limited to a dry powder, liquid concentrate, cereal additive, cake mix, or spread.
