Can Raw Smoothies Improve Eye Health? December 09 2013

Brightly colored fruits and vegetables make delicious smoothies and also contribute to healthy eyes.  Vitamins in these raw foods can protect against such conditions as night blindness, eye infections, and degenerative eye diseases. Although supplements are plentiful and widely marketed, health professionals stress the importance of a good diet. Making raw smoothies with your high performance blender is one way to give your diet a boost while taking care of your vision.

Seeing Better with Vitamin A

Children and pregnant and lactating women who have a vitamin A deficiency are at a risk for blindness. In fact, night blindness is the first symptom of an eye disease that may be linked to insufficient vitamin A in the diet.  This vitamin nourishes cells in the retina that are responsible for creating nerve impulses triggered by light.  Vitamin A also helps to relieve dry eyes and can guard against glaucoma.   Look for yellow, orange, red and green vegetables and fruits for good sources of vitamin A.  Examples include:  spinach, pumpkin, kale, collard greens, cantaloupe, and apricot. Vitamin A is a fat-soluble nutrient and will build up in the body.  It is important to get enough, but not to get too much of this vitamin.  The recommended daily intake for girls who are more than 10 years of age and women is 800 mcg; boys older than 10 and men should take 1,000 mcg a day.

Vitamin D Lowers Risks

Vitamin D in sufficient amounts lowers the risk of eye infections as well as protecting overall immunity and helping you maintain good vision.  Most recently, studies published in leading ophthalmology journals show a link between vitamin D deficiency and an increased risk of macular degeneration, a progressive disease resulting in blindness. Fortified juices, daily milk and almond milk are good sources of vitamin D and can easily be used in your smoothies and sauces. Daily requirements of this fat-soluble vitamin vary by age.  Those below age 50 should consume 200 IU, men and women between 51 and 70 need 400 IU, and those older than 70 require 600 IU.

Vitamin E and Your Immunity

Vitamin E is an antioxidant and can be found in sweet potatoes and nuts, as well as vitamin-fortified cereals and peanut butter.  It helps the immune system and plays a role in reducing the risk of blindness in later years. Foods that are good sources of vitamin E include kiwi, avocado, peach, pumpkin, and papaya.  All can be used found in soup, smoothie or sauce recipes. Vitamin E, which is also a fat-soluble vitamin, must come from either supplements or diet because the body cannot manufacture it through any biological function.  The recommended daily requirement for vitamin E is 22 IU for men and women.  Women who are lactating need 28.5 IU every day, and children between the ages of 4 and 8 require 10.5 IU.

Vitamin C: The Other Antioxidant

Many nutritionists and medical professionals consider this vitamin a good source for making overall immunity stronger.  It is also thought to improve eye health because it can protect against eye infections.  Other advantages are said to include antioxidant and anticarcinogenic properties. Among the raw fruits and vegetables high in vitamin C are peas, strawberries, oranges, kale, broccoli, carrot, apricot, papaya and collard green. The recommended daily dosage of this water-soluble vitamin is 75 mg for women and 65 mg for men

Eye Support with Lutein and Zeaxanthin

Colorful vegetables contain these two important substances, which are referred to as xanthophylls.  Both lutein and zeaxanthin are present at high levels in the human eye. Specifically, these compounds are found in the macula and provide an antioxidant benefits that keep the cells in the eyes healthy. Zeaxanthin can protect the photoreceptors in the eye as well as the retina and macula.  Some studies *** indicate that these two substances play a larger role in reducing the incidence of macular degeneration than vitamins E or C.  Studies suggest *** that adults should eat foods that contain 6 mg of lutein and zeaxanthin a day. If you are in the habit of making raw smoothies with richly colored fruits and vegetables, the changes are good that you are giving your body the right amount of vitamins and other nutrients for optimal eye health.  Rather than seeking out supplements and researching to find credible manufacturers, it is far easier to make smoothies using some of the colorful fruits, vegetables along with fortified milk or juices.

Can Smoothies and Supplements Promote Healthy Bones? October 30 2013

Calcium smoothieIt seems that there are virtually thousands of supplements and ingredients on the market that claim to protect against nearly every imaginable ailment and affliction. To add to this confusion, websites selling supplements are coming online at an incredibly fast rate. If you are looking for the right supplements for bone health, a good place is a basic list of vitamins and minerals, the proper daily dosage based on age, and how you can derive the most benefit from them.  ...Or, you could try a concoction of your own... A Calcium Smoothie?


Facts about Bones


Bones are very much like tissue in the body, and they are changing all the time as cells die and are replaced. The aging process does place a premium on the importance of keeping bones strong to prevent osteoporosis and loss of bone mass. While age is related to bone mass in women, healthy bones can be maintained with proper levels of calcium, vitamin D and protein. The amount of physical activity and the exposure to environmental risks such as smoking and alcohol consumption also affect bone health.


During childhood bone mass grows and in adulthood the rate of new growth and the rate of bone mass decline are about equal. After menopause, however, women will begin to experience loss of bone mass. Men who are over 50 years of age also lose bone mass but at a rate that is half that of women.

The Calcium Connection to Vitamin D


If you take calcium supplements, it is necessary to have vitamin D in sufficient quantities for the calcium to be absorbed. A person whose blood test shows a vitamin D deficiency will need to take supplements or make dietary changes to protect the body’s skeletal structure.  


One way to assure that you get the daily allowance of calcium and vitamin D is to use fortified dairy milk or almond milk when you make raw smoothies. For example, eight ounces of almond milk provides 45% of the calcium and 25% of the vitamin D required on average in a day. Vitamin D is added to fortified diary milk in the US to help consumers meet the recommended dietary allowance (RDA).


Are There Risks to Calcium Supplements?


According to an article published by the Daily Mail on July 30, 2010, results of a study that appeared on the British Medical Journal’s website suggested that women who take calcium supplements may be at an increased risk of suffering a heart attack. Researchers concluded that the supplements, which were 500mg or greater, contributed to the hardening of arteries. However, the researchers determined that those who consumed a high amount of calcium through diet were not at the same risk. Another caveat to mention is that patients who were baking supplements of both calcium and vitamin D were not included in the study.


What conclusion can be drawn from this study? Women who are postmenopausal should make sure that they get enough vitamin D and calcium through fortified milk, grains and yogurt. Yogurt is a healthy base to use when making raw smoothies in your high performance blender.


Protein and Bone Health


  1. Better Bones website that older adults who have suffered a hip fracture have better post-surgical outcomes if they have the right amount of protein in their blood system.  She notes that they have fewer complications and tend to stay in the hospital for a shorter time.  While too little protein can be dangerous, we are more likely in the US to suffer the consequences of too much protein, which can lead to the loss of vital minerals and the undermining of bone health.


There is a complex set of variables in diet that can influence how well an older person recovers from fractures and there is little evidence that protein levels alone make a difference one way or the other. Generally, though, medical experts agree that protein does not build bone. It does help to build muscles and keep tissues and organs healthy.


While calcium and vitamin D supplements can help promote healthy bone mass in people who are more than 50 years old, it is best to discuss concerns with your doctor before starting on a new regimen. Making raw smoothies with ingredients that provide the right amounts of calcium and vitamin D is a good alternative to supplements.
