Nutraceuticals are defined as a food or food ingredients that prevent and treat diseases. They contain dietary supplements like proteins, vitamins and minerals, compound derived from natural sources. They have functions about delaying, preventing and treating chronic inflammatory diseases due to the presence of the phytochemicals. They have anti-inflammatory effects by inhibiting of the activation of NF-κB, blocking the overexpression of tumor necrosis factor and interleukin-1, downregulation of the overexpression of cell adhesion molecules and inhibiting phospholipase A2, COX-2, lipoxygenease, iNOS, myeloperoxidase and inhibiting reactive oxygen species (ROS) generating enzyme activity and increasing ability to scavenge ROS. They have antioxidative role that can reduce the level of ROS and free radicals. They have effects on the process of lipid oxidation that inhibit or slow the formation of free alky radicals and cut off the free radical chain reactions.

1. Introduction

In recent years, the consumption of natural products or functional foods are increased and enlarged segment of food industry. At the same time, Nutraceuticals are increased using as an alternative for pharmaceutical industry especially variety of diseases and cancers in humans and animals.

Firstly, nutraceutical is a term used by Stefane De Felice Nutraceuticals is defined as a food, bioactive products or food ingredients that prevent and treat diseases [1, 2, 3, 4]. They are not drugs but they have pharmacologically active substance [2]. They contain dietary supplements like proteins, vitamins and minerals, compounds derived from natural sources. They provide health and medical benefits that delay, prevent and treat chronic inflammatory diseases due to the presence of the phytochemicals [1, 2, 3, 4].

They have anti-inflammatory effects by inhibiting of the activation of NF-κB, blocking the overexpression of tumor necrosis factor and interleukin-1, downregulation of the overexpression of cell adhesion molecules and inhibiting phospholipase A2, COX-2, 5-LOX, iNOS, myeloperoxidase and inhibiting ROS generating enzyme activity and increasing ability to scavenge ROS. They have antioxidative role that can reduce the level of ROS and free radicals. They have effects on the process of lipid oxidation that inhibit or slow the formation of free alky radicals and cut off the free radical chain reactions. They have intracellular signaling pathway modular effects [2, 3, 4].

The foods including antioxidative nutraceuticals are fruits (grape, citrus, blueberries, strawberries, blackberries and crowberries), vegetables (tomato, beans, broccoli, beet, mushroom, corn, white cabbage, kale, cauliflower, spinach, garlic, onion, cacao beans and soybean), spices (rosemary, oregano and thyme), herbs (sage) and beverages (tea, wine) [4, 5, 6].

People’s interest about nutraceuticals is increasing day by day due to various diseases. According to the global market data, China will be first nutraceutical market as lifestyle. The nutraceutical sector is affected by the stringent regulations and approval process of European Union. Due to the country, there are different names of laws on nutraceuticals. Nutraceuticals are using different definitions and terms including dietary supplement in USA, Natural Health Product in Canada, complementary medicines in Australia, food supplements in European Union and foods for special dietary in India [7].

With the increasing technology in the food, health and pharmaceutical sectors, the orientation to functional foods is increasing and the competition is accelerating. The sales of global market for nutraceuticals are expected to be US$250 billion by 2018 [8].

When nutraceuticals are evaluated by consumers, the consumption of food has undergone changes in the past three decades. The easing of access to media and internet, increasing in scientific studies and obesity related diseases are increased to sale nutraceutical products by consumers. Between 2018 and 2025 years, the growth rate of this sector is assumed to exceed 9.7%. The countries including Brazil, China, India, South Korea, Poland and Mexico are increasing to use functional foods. The global market of nutraceuticals is assumed to be $578.23 billion by 2025 at CAGR of 8.8% [9].

Inflammation is a protective response against the initial cause of cell injury. Inflammation is classified as acute and chronic. Acute inflammation is first response mechanism against infections, trauma, physical and chemical agents, which are induced wound healing. If this mechanism occurs persistent, it takes chronic phase [3, 10]. The process of inflammation contain vascular and cellular changes including of swollen, redness, local heating and loss of function. The permeability of capillaries is increased, exudate including the fluid and other elements leak into the body cavities. The inflammatory cells, leucocytes and other phagocytic cells migrate through the affected region. The lytic enzymes release from lysosomes of cells. During the inflammation, chemical mediators are synthesized proinflammatory cytokines (histamine, 5-hydroxytryptamine, bradykinin, leukotrienes and prostaglandins), selectins, integrins and immunoglobulins are stimulated for releasing [1]. Arachidonic acid metabolites including prostaglandins and leukotrienes are stimulated by the increasing expression of phospholipase A2. ROS are released from the inflammatory cells including neutrophils and macrophages. NADPH oxidase, xanthine oxidase and myeloperoxidase are seen increasing due to the ROS. The inflammatory cytokines, cell adhesion molecules and enzymes are regulated by the activation of the transcription factor NF-κB [3, 11].

ROS generate intracellularly as natural by endogenous and exogenous sources. Endogenous ROS including superoxide, hydrogen peroxide and nitric oxide (NO) have functions in cell signaling and homeostasis [12]. ROS has functions in regulation of cell survival. At the moderate levels of ROS signaling support cell proliferation and survival. At the upper levels of ROS cause cell death [12, 13]. There is a relationship between ROS production and oxidative stress that play a role on redox signaling from the organelle to the cytosol to nucleus [12, 14].

ROS are present in different cancer types and age related diseases as neurodegeneration, inflammation, diabetes, vision and sensory loss [12]. ROS and reactive nitrogen species damage significant biological molecules which are lipids, DNA, essential cellular proteins. Oxidative stress is imbalance between the formation of free radicals and antioxidant defense mechanism [15, 16].

Enzymatic and nonenzymatic antioxidant systems which are superoxide dismutase, catalase, glutathione peroxidase, lipid soluble vitamin E, carotenes and water soluble vitamin C arrange between ROS and antioxidants [4, 17, 18].

Oxidative stress starts the oxidation of polyunsaturated fatty acids (PUFA), proteins, DNA and sterols. The oxidative stress reduce in the body with consumption of fruits and vegetables including high amounts of anti-oxidative nutraceuticals and for this reason, incidence of cancer and cardiovascular diseases decrease [4, 6]. According to the recent studies, there is a relationship between ROS and atherosclerosis, vasospasm, cancers, trauma, stroke, asthma, hyperoxia, arthritis, heart attack, age pigments, dermatitis, cataractogenesis, retinal damage, hepatitis, liver injury and periodontitis [4, 19, 20].


2. Nutraceuticals

2.1 Vitamin E

Vitamin E (alpha-, beta-, gamma- and delta-tocopherol, alpha-, beta-, gamma- and delta-tocotrienol) is quite effective antioxidant and beneficial aspects for rheumatoid arthritis [4, 21, 22]. Also, vitamin E has anti-inflammatory effects in animal recent studies [4, 23]. Tocopherols and tocotrienols have nonpolar structures and consist in the lipid phase. Tocopherols are member of biological membranes and. Tocopherols have antioxidants property that defend polyunsaturated fatty acids into the membrane and LDL [4, 24]. The anti-inflammatory and anti-oxidant effects of Vitamin E and its derivatives are summarized in Table 1.

2.3 Phenolic compounds, polyphenols

The polyphenols are phenolic compounds that are defined as a benzene ring bearing one or more hydroxyl groups attached to the ring. They are including plants, vegetables, fruit, vines, tea, coffee and microalgae [2]. The phenolic compounds are classified as simple phenols, benzoquinoes, phenoic acids, acetophenones, phenylacetic acids, hydroxycinnamic acids, phenylpropens, coumarins, chromones, anthraquinones and flavonoids [4]. According to the recent articles, polyphenols have antioxidant [2, 4], anti-inflammatory [2, 55], anticancer [2, 56], antibacterial [2, 57], antiatherogenic [2, 58], antiangiogenic [2, 59], antimutagenic and free radical scavenging properties [4].

Flavonoids, which are water-soluble [3], are popular group of polyphenols and classified as flavones, flavonols, catechin or flavanols, anthocyanins and isoflavones. Flavonoids consist as free aglycones or with sugars connected the chemical structures to generate glycosides. Flavonoids have anti-inflammatory functions by inhibiting the enzymes responsible for production of phospholipase A2, cyclooxygenase and lipoxygenase [2, 3, 63]. The beneficial effects to health of phenolic compounds are listed below in Table 3.

3. Conclusion

Nutraceuticals are alternative or functional foods or ingredients that prevent or treatment of inflammatory and oxidative stress induced diseases. Nutraceuticals are cheaper and easier availability than prescription drugs. For this reason, consumer’s demand has increased in recent years.

The effecting on pathogenesis and activity of diseases are also essential scientific subject for animal and human health. When the effects of nutraceuticals on oxidative stress and inflammatory related disease are discovered, usages of nutraceuticals in Pharmacology and scientific studies are seen huge growth. The relation between beneficial effects of nutraceuticals and diseases are required to research long-term multidisciplinary studies.

People are searching minimally processed food and want to benefit nutritional values and live healthy. For this reason nutraceutical market is growing day by day.

The aging, fast rising population, changing lifestyle and lifestyle induced diseases, healthcare research, increasing cases of cancer, economic and public problems are directed people to benefit better choices.

As a conclusion, nutraceuticals are important for nutrition of human and animal. The consumption of nutraceuticals is necessary to reduce effects of the oxidative stress and inflammation related diseases.
