Healthy Nutrition For The Elderly

Healthy eating and nutrition for the elderly is greatly impacted by several factors, one of them being a change in body composition. During the later years in life, the body will lose bone and muscle and gain fat because the hormones aren’t very active anymore.

There are many factors which hinder an elderly person’s health. The information below will help you to lead a healthy life – no matter how old you may be.

Water
Water in the body decreases with age, so many older folks will become dehydrated very easily. Sometimes they won’t feel thirsty, while other times it’s too much work to pour a glass a water. With this in mind, it’s recommended that they drink at least 1 ounce of water for every 2.2 pounds of weight.

Protein
At this stage in life, protein is very important. Protein is needed to support a healthy immune system and prevent the wasting of muscle. Since energy needs are less, older folks should eat high quality protein such as eggs, lean meats, poultry,and fish.

Carbs and fiber
Carbohydrates are the main source of energy for the entire body. You can find carbs inbread,cereals,
pasta,and other grain products. A diet that’s high in fiber and water will help to prevent constipation as well.

Fat
Fat intake for the elderly should be limited, not eliminated. You can limit fat by choosing lean meats,low fat dairy products, and food preparation methods that don’t include frying.

Iron
For the elderly, iron deficiency can be seen with those who aren’t eating much. Good sources for iron include lean red meats or breakfast cereals.

Zinc
Zinc intake is normally with the elderly, and to make matters worse, it’s not absorbed very well either. Meat, poultry, and fish should be a part of your diet to help you meet the requirements for zinc.

Calcium
Calcium is one ingredient that most elderly folks simply aren’t getting enough of. Most believe that milk upsets their stomach, and therefore they will avoid it. They should be getting around 1,500 mg of calcium a day, and nonfat powdered milk can be used in recipes as a substitute for milk. Other foods such as yogurt, low fat cheese, and broccoli can also help you meet the requirements for calcium.

Vitamin B12
In order to absorb the benefits of B12, the intrinsic facotr must be produced by the stomach. Most elderly people suffer from a deficiency in B12 because they have a condition known as atrophic gastritis. This
condition causes inflammation of the stomach,bacterial overgrowth, and the intrinsic factor.Without the intrinsic factor, this vitamin can be
absorbed.

Each one of the above nutrients are needed to keep an aged body in good health. Elderly individuals should try to stay active and strive for a well balanced diet. Even though the aged body isn’t the same as it used to be, proper care and the right nutrients can help the elderly enjoy a healthy and long life.

How The Optical Eyewear Helps To Improve Eyesight

Choosing lenses for your glasses is an arduous task if not a frustrating one. The problem is exacerbated by the fact that you only get the final product when you collect your eyewear from a certified optician.

Fortunately, you don’t have to risk making the wrong choice anymore. Here are some invaluable factors to consider when choosing:

Material

This is one of the most misunderstood aspects of eyewear and a major cause of wrong choices. The material you choose affects your vision and life of your eyeglasses. Main materials include:

Glass: These offer exceptional optical clarity, scratch resistance and an anti-reflective coating adheres perfectly. Nevertheless, they have a downside in their delicate nature and heaviness. Glass easily cracks and breaks thus making it an expensive option.
Plastic: These were introduced in the 1940s by a California-based company. They are made from lightweight plastic polymer C39 and offer good optical quality, shatter and crack resistance. However, they require a scratch-resistant coating.
Polycarbonate: Are hailed for impact resistance, which is 10 times more than the other materials, lightweight quality, 100% UV resistance without a special coating and thinness. However, they require scratch-resistance coating and require anti-glare for better vision.

Others materials include aspheric and NXT though they are not common in day to day eyewear.

Edge Thickness

FDA regulates minimum centre thickness in both concave and convex glasses. However, your optician will be able to determine their shape without going against the regulations to ensure your vision is not worsened.

Type of Lenses

These vary in type. You can opt for single-vision or unifocal that provide vision correction for a given distance. Double vision also known as bifocal models, offer two different corrections while the more holistic progressive vision type behave like bifocal ones but offer an invisible boundary line.

Aspheric Design

To get aesthetically appealing glasses, you should go for an aspheric design with a gradually changing lens curvature from the centre to the edges. They avert magnification of your eyes while also improving optical clarity in peripheral vision.

Index of Refraction

This technical detail implies the ratio of speed of light in a vacuum divided by the speed of light in your glasses material. It is all about how efficient your eyewear will be. The higher the refractive index of the material, the less the material required to bend light. This means a higher refractive index translates to a thinner more appealing and efficient product.
