Equipment for your Abs

If you are looking to buy equipment for your ab workouts, there are some really good deals for equipment. The amount of money that you spend does not reflect on the quality of the equipment that you want to purchase. Some of the cheapest items on the market will produce some of the greatest improvements overall; you do not have to buy high-dollar workout equipment to get the body that you want.

One of the best items you can use is the exercise ball. These can be found for a very reasonable price and they work great. These balls can be used for the die-hard ab workers or the experimental fitness types. Using this ball, you can work all of your abdominal muscles. The down fall is they can be rather large and not very portable, unless you deflate them and have a way of inflating them on the go.

The next item is the ab wheel. This is a little invention that is small in size and normally very reasonably priced. The way you use this device is by getting on your hands and knees and placing your hands on the handle bars. Then you slowly roll the wheel forward keeping your back straight. Do not extend yourself to where you bow in the middle. This can injure your back. Once you extend as far as you safely can, you slowly bring the wheel back to the starting position, keeping your ab muscles taut. This device makes for a very portable and is small enough to travel quite easily in a suitcase.

The Pilates ab exerciser is another ab tool that you can use. The Pilates ab exerciser is a great device to use because it can be applied to all levels of fitness users. This simple to use item is extremely portable and compact. The price range is also very affordable. The device is used by placing your feet in the foot holders, grasping the handles and extending your back. This contracts your abs for a thorough workout.

Also I can recommend Ab Lounge Ultra. Ab Lounge is great piece of equipment.

When it comes to working your ab muscles, there are many options that you can choose from. Some of them are very inexpensive and yet produce awesome results. You just need to have the will-power to keep up with your routine and not hide your piece of equipment so that you forget about it. Most ab machines are also quite portable and can be taken on vacations or weekend getaways if you so desire, so that you can maintain your workout routine.

Herbs and Spices and Antimicrobials

Herbs and spices are used widely in the food industry as flavours and fragrances. However, they also exhibit useful antimicrobial and antioxidant properties. Many plant-derived antimicrobial compounds have a wide spectrum of activity against bacteria, fungi and mycobacteria and this has led to suggestions that they could be used as natural preservatives in foods (Farag et al., 1989; Ramadan et al., 1972; Conner and Beuchat, 1984a,b; Galli et al., 1985). Although more than 1300 plants have been reported as potential sources of antimicrobial agents (Wilkins and Board, 1989), such alternative compounds have not been sufficiently exploited in foods to date.

In this post, the antimicrobial compounds from herbs and spices are reviewed and the barriers to the adoption of these substances as food preservatives are discussed. The mode of action of essential oils and the potential for development of resistance are also discussed. The focus is primarily on bacteria and fungi in prepared foods.

Barriers to the use of herb and spice essential oils as antimicrobials in foods

Since ancient times, spices and herbs have not been consciously added to foods as preservatives but mainly as seasoning additives due to their aromatic properties. Although the majority of essential oils from herbs and spices are classified as Generally Recognized As Safe (GRAS) (Kabara, 1991), their use in foods as preservatives is limited because of flavour considerations, since effective antimicrobial doses may exceed organoleptically acceptable levels. This problem could possibly be overcome if answers could be given to the following questions:
• Can the inhibitory effect of an essential oil (a mixture of many compounds) be attributed
to one or several key constituents?

• Does the essential oil provide a synergy of activity, which simple mixtures of components
cannot deliver?

• What is the minimum inhibitory concentration (MIC) of the active compound(s) of the
essential oil?

• How is the behaviour of the antimicrobial substance(s) affected by the homogeneous
(liquid, semisolid) or heterogeneous (emulsions, mixtures of solids and semisolids)
structure of foodstuffs?

• Could efficacy be enhanced by combinations with traditional (salting, heating, acidifica-
tion) and modern (vacuum packing, VP, modified atmosphere packing, MAP) methods
of food preservation?

An in-depth understanding of the antimicrobial properties of these compounds is needed to answer these questions but such understanding has been lacking, despite the burgeoning literature on the subject. Methodological limitations (discussed in more detail below) in the
evaluation of antimicrobial activity in vitro have led to many contradictory results. More-
over, there have been too few studies in real foods (these are considered laborious and often
lead to negative outcomes). There is also a need to investigate the appropriate mode of application of an essential oil in a foodstuff. For instance, immersion, mixing, encapsulation, surface-spraying, and evaporating onto active packaging are some promising methods
of adding these compounds to foods that have not been extensively investigated.

Insect Repellent Properties

The herbal spices have good insect repellent properties. Powdered plant parts or extracts of
seed or essential oils or active ingredients separated from essential oils and oleoresins of spices are used as insect repellents.

The repellent action is noticed against many storage pests of grains and pulses. Herbal spices can also be used as mosquito repellents. The essential oil of basil and piperidine alkaloid separated from long pepper repels mosquitoes.

Medicinal properties

Herbs and spices are known for their medicinal properties and have been used in traditional medicines from time immemorial. Powdered spices are either externally applied or taken
internally for various ailments.

The essential oils of many herbs and spices are used in pharmaceutical preparations. The
essential oil of coriander is reported to be analgesic, dill and anise oils as antipyretic, coriander, celery, parsley and cumin oils as anti-inflammatory. Recently, anticarcinogenic property has been reported for essential oils of cumin and basil and these can be used as protective agents against carcinogenesis. Also, methanol extracts of allspice, marjoram, tarragon and thyme strongly inhibited platelet aggregation induced by collagen in humans.
