The phenolic compounds are the main component responsible for antioxidant activity, is mainly due to their redox properties, which can play an important role in absorbing and neutralizing free radicals, quenching singlet and triplet oxygen, or decomposing peroxides. Recently, phenolics or polyphenols have received considerable attention because of their physiological functions, including antioxidant, antimutagenic and antitumor activities. They have been reported to be a potential compound to combat free radicals, which are harmful to our body and foods systems (Nagai et al., 2003). Phenolic constituents are one of the major group of compounds acting as primary antioxidants especially as free radical terminators (Oviasogie et al., 1985; Ka, 1999). The level of antioxidants as evidenced in this study imply the presence of phenolics. Phenolic compounds comprise a large group of biological …show more content…

In the article “The End of Food,” Lizzie Widdicombe describes an advancement of our food culture through a new product developed by three young men living in San Francisco’s Tenderloin district. After failing to produce new inexpensive cellphone towers on a hundred seventy thousand dollar investment, the three men went on to try and develop software with their remaining funding. While trying to maximize their funding’s longevity, they realized that their biggest budget impediment was food. In fact, it reached the point where their diet comprised of mostly fast food, and eventually they despised the fact that they had to spend so much time and money on eating. Due to this hardship, Rob Rhinehart, one of the entrepreneurs, came up with the
All types of fats are necessary for good health. Cooking oil is a significant ingredient in almost all our dishes and selecting the right one for use is vital for our health. The following are some simple oil basics that can help us select the right oil. All oils have fatty acids like saturated (SFA), poly-unsaturated (PUFA) and mono-unsaturated (MUFA). According to the Indian Council of Medical Research, ideal oil is one, which has SFA : MUFA : PUFA ratio of 27-33% : 33-40% : 27-33%. While purchasing oil we should ensure that the oil has low saturated fats (less than 2 g for every 10 g), zero or no trans fats and higher amounts of MUFA and PUFA. This combination is the best suitable for a healthy human heart. Alternately, we can also use two oils separately or rotate our oil every two
The definition of homemade has changed drastically throughout time. Rachel Jones recognizes this in her article “Homemade is the New Organic,” published in 2013 by The Atlantic. It is in this article that she explains how media nowadays has raised expectations on home cooking. Jones` purpose is to make readers aware of the unrecognizable and unrealistic expectations that the modern media subtly places on us when it comes to home cooking. Based on the content and the examples presented in the article, it appears as though the author`s intended audience is people who cook, or more specifically, mothers that cook. Jones begins building her credibility with past experiences and reputable sources, uses facts to back up her claims, and appeals to reader`s emotions.
Science-fiction novels have imagined thousands societal advancements, with many of which taking form in reality. A recent addition to the ranks of the helicopter and submarine is a substitute for food called Soylent. Soylent is a drink crafted from the base nutrients we require from food, theoretically meaning that someone who drinks Soylent does not need regular food. Creator Rob Rhinehart has stated that he wishes for Soylent to replace most meals, causing increased efficiency for all people, while reforming the food industry. This does not mean Soylent would ever replace meals as a cultural centerpoint, but that it may replace meals that serve no social or cultural purpose.
Phenolic acids are secondary plant metabolites widely distributed in foods, especially fruits and vegetables. In recent years, phenolic acids have attracted a lot of attention because they exist ubiquitously in plants and play protective roles. Phenolic acids possess interesting biological properties, (Beilin, Stocker, & Croft, 1997) that render them interesting to study. They are widespread in crops such as fruits, vegetables, herbs, grains, and seeds and derived foods such as juices, wines, and oils, (Graf, Ameho, Dolnokowski, Milbuty, Chen, & Blumberg, 2006). Phenolic compounds play a key role in thwarting the negative impacts of oxygen and nitrogen reactive species (ROS/RNS), maintaining the redox homeostasis of biological fluids and preventing conditions such as cardiovascular diseases, atherosclerosis, and other degenerative pathologies, such as cancer, diabetes, Alzheimer’s and Parkinson’s diseases, (Shahrzad & Bitsch, 1998).
Oxidative stress is essentially defined as the imbalance in the equilibrium of antioxidants systems in the human body. Oxidative damage in aerobic organisms can be caused by certain molecules known as reactive oxygen species (ROS). These reactive species are ones that cause oxidative damage in biomolecules. In order to maintain equilibrium of these substances, the human body has various endogenous antioxidants and phase 2 proteins which have evolved to defend against any harmful effects of ROS or any other reactive species. In normal physiological conditions, a balance is maintained between the ROS production and their detoxification by the appropriate antioxidants and phases 2 proteins. (Uttara, Singh, Zamboni & Mahajan, 2009). Oxidative stress can occur due too many pathological conditions, when the balance of prooxidants and antioxidants is disturbed oxidative damage could accumulate in proteins, lipids, carbohydrates and nucleic acids. In severe cases these events can lead to cell death. The process can directly alter the antioxidant systems by either inducing or inhibiting the proteins which take part in these systems. Moreover it can also cause the depletion of storage of antioxidants such as glutathione, vitamin E and many more in cells. (Thomas 2006). Antioxidants are defined as any substance which has the ability to inhibit, reduce or repair the damage as a result of an ROS in a biomolecule. The general three mechanisms that are used by antioxidants include the inhibition of ROS generation, the repair of damage induced by ROS and scavenging for ROS molecules. Since ROS plays a precarious role in both physiology and pathophysiology in the human body, it is vital that the endogenous antioxidants and phase prote...
In the past decades the incidence of heart disease has increased, about three million people dying of cardiovascular disease in China per year (according to statistics from the Ministry of Public Health of China), which draws people’s great concern to find ways to take precautions. With the development of element analytical method, some types of chemical substances that are beneficial to cardiac health have been found. Lycopene is a very popular natural anti-oxidants found in recent years (Dai, 2011), as well as capsaicin and dietary fiber. Whilst some research focuses on the mechanism of action, little attention has been paid to usability issues, in particular to the generalization of health-giving chemical substances in ordinary meals. There is a lot of evidence that vegetables can positively contribute to prevent heart diseases, by supplying biologically active components. This article continues previous research in the field of Biochemistry and Medical Science, mainly trying to study the effective components which can prevent heart disease in edible vegetables.

Flavonoids are widely distributed in plants, fulfilling many functions. Flavonoids are the most important in plant pigments for flower coloration, producing yellow, red, or blue pigmentation in plants designed to attract pollinators. In higher plants, flavonoids are involved in UV filtration, symbiotic nitrogen fixation and floral pigmentation. They may also act as chemical messengers, physiological regulators, and cell cycle inhibitors. Flavonoids, which are polyphenolic compounds, are a class of plant secondary metabolites possessing a broad spectrum of pharmacological activity including anti-cancer activities. Among the various natural products, flavonoids have attracted much attention due to their remarkable spectrum of pharmacological activities such as antioxidant, antimutagenic, antibacterial, antiangiogenic,anti-inflammatory, antiallergic, modulators of enzymatic activities and anti-cancer activity. Flavonoids have been found act as protein kinase inhibitors which can prevent alterations in phosphorylation that result in uncontrolled cell division, inhibition of apoptosis, and other abnormalities. Flavonoids can be known as angiogenesis agents. Angiogenesis is a physiological process resulting in formation of new blood vessels from pre-existing vessels. Antigiogenesis cause rapid growth of solid tumor and tumor metasta-sis are promoted by uncontrolled tumor angiogenesis. The flavonoids can control this growth of tumor. Besides that, flavonoids also can act as antioxidants which known as substances that delay, prevent or remove oxidative damage to a target molecule (Ravishankar et al., 2013).
