ABSTRACT Brewing is an ancient industry that dates back 9000 years and to date more than 100 billion liters of beer are consumed annually. In Kenya alcoholic beverages industry is more liberal with the previously referred to as ‘illicit alcoholic beverages’ being legalized in November 2010, by the passing of Alcohol Law (Mututho Law). Production and consumption of some alcoholic beverages has been on increase partly due to high cost of commercial alcoholic drinks. People have died, other...
ABSTRACT Population growth, shortage of food due to unpredicted weather coupled with HIV/AIDS has increased nutritional deficiencies in people living in developing world. Use of micronutrients presents a low-cost strategy for achieving large reductions in death caused by malnutrition. The indigenous green leafy vegetables are of much importance among food crops as they provide adequate amounts of vitamins, immune boosting trace elements and anti-oxidants. The nutritional value of the indigeno...
ABSTRACT Cosmetics are generally used to improve the appearance by the removal or correction of blemishes and to treat diseases of the human skin and hair. Skin-lighteners which include hydroquinone, mercury, arbutin, kojic acid, ascorbyl glucoside, magnesium ascorbyl phosphate have been frequently used in skin lightening creams and soaps. However chronic exposure to mercury compounds in skin lightening creams and soaps may lead to various disorders such as nephritic, peripheral neuropathy, a...
ABSTRACT Kenya is endowed with nature where hundreds of medicinal plants are available. During photosynthesis and respiration process in plants, animals and other organisms, ions of metal elements play a major role with a few of the elements being essential to the body as nutrients. Trace elements Zn, Cr, V and Se with known immunological response and healing properties were analysed from selected medicinal plants available in Kenya. These plants were; Prunus africana, Urtica massaica, Mayten...
ABSTRACT Heavy metal pollution in soil and water arising from anthropogenic sources continue to pose a great challenge to human and animal population. In Samburu County conflicts arising from cattle rustling, military trainings in the county which have led to heavy use and disposal of arms, a growing population without proper sewerage facilities, increase in the number of aging automobiles and fertilizers from the wheat and barley farms in the highlands of Lorroki are the biggest contributors...
ABSTRACT Medicinal plants are essential components of primary health care, especially for rural communities indeveloping countries. The medicinal plants contain essentialelements that are beneficial therapeutically. For example zinc plays a vital role in wound healing, nervous system, reproductive system and immune system. Chromium helps in metabolism and management of type-2 diabetes. Sodium is the chief extracellular ion and helps to maintain the body’s fluid balance while potassium is th...
ABSTRACT Water pollution is an overbearing environmental challenge due to increasing anthropogenic activities from industrial, agricultural and domestic fronts. While data on the water quality such as heavy metals and physico-chemical parameters is enormous, that onpolycyclic aromatic hydrocarbons(PAHs) presents a research gap. The 16 priority polycyclic aromatic hydrocarbons in the environment have increasingly become a health risk as a result of anthropogenic activities. The study was unde...
ABSTRACT Noncommunicable diseases (NCDs) such as cardiovascular disease, cancer and chronic respiratory diseases are economically burdening, causing more deaths worldwide than all other causes of death combined. The global burden of these diseases is projected to increase tremendously with an estimated global death of 75 % by 2030. Unhealthy diets, tobacco use, exposure to environmental carcinogens and physical inactivity are documented as the major causes of NCDs. The major contributing fact...
ABSTRACT Carotenoids are a group of naturally occurring phytochemicals, many of which are important in human nutrition and health. In particular, lycopene and its analogues may have potent antioxidant properties to protect cells and tissues from oxidative stress and free radicals, and thus contribute to enhancement of immune functions of the body. These antioxidants may also prevent damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA. Diets rich in these p...
ABSTRACT Heavy metal pollution is among the leading health concerns all over the world because of their long-term cumulative effects. Consumption of food crops contaminated with heavy metals is a major food chain route for human exposure. Khat (Catha edulis forsk), a plant used as a stimulant is grown in certain areas of East Africa and the Arab Peninsula. In Kenya, it is cultivated in Embu and Meru counties and distributed to consumers in other counties who include young children. Due to inc...
ABSTRACT Fruits are a good source of micronutrients, yet they are less consumed. Kakamega County has various types of fruits either planted or growing wildly. Most of the fruits consumed are exotic such as avocadoes, mangoes, pawpaw, oranges, passion fruits and pineapples while the wild and indigenous fruits are usually neglected, seen as weeds and food for children and very poor rural people. In Kakamega County the indigenous fruits are well distributed among the rural areas and members of ...
ABSTRACT Majority of Kenyans lack access to clean water due to increased population growth, high rate of industrialisation and poor waste management. The situation may worsen if immediate measures are not taken. Lead and cadmium are the main heavy metals in contaminated water and their harmful effects such as lung cancer, mental retardation and nerve disorder cannot be underestimated. Available methods for removing these metal ions from water such as use of activated carbon are very expensive...
ABSTRACT Every year millions of tones of industrial wastes and municipal sewage are dumped into the world oceans as rivers carrying agricultural wastes discharge their waters into the ocean. The Mombasa inshore (Kilindini and Portreiz) waters and Sabaki/Malindi bay complex are characterized by rapid urbanization, industrial activities including shipping, agriculture and tourism. As a result, the coastal fauna, sediments and sea water are polluted with heavy metals, raw sewage and organochlori...
ABSTRACT Prolonged use of synthetic chemical pesticides is environmentally undesirable, results in rapid development of resistance among insect pests and is economically unmanageable by small-scale farmers. Kenya has unexplored potential in controlling lepidopteran pests using proteinous delta-endotoxins sourced from local isolates of a naturally occurring bacterium, Bacillus thuringiensis Berliner (Bt). This study attempted to identify the insecticidal proteins, present in some Kenyan Bt is...
ABSTRACT Biomagnifications of toxic heavy metals to man through aquatic life occurs via industrial, runoff, agricultural, municipal and urban waste. Heavy metals such as lead (Pb), nickel (Ni) manganese (Mn) and cadmium (Cd) have World Health Organization (WHO) limits above which they are toxic. Some of the toxic effects include; reduced growth and development, cancer, damage to the nervous system, and in extreme cases death. Athi River,the second largest river in Kenya has its source in a de...
