Nevertheless, its importance is not fully recognized. The objective of this paper is to review the impact of malnutrition and of nutritional treatment upon outcomes and mortality in older people with hip fracture.
We searched the PubMed database for studies evaluating nutritional aspects in people aged 70 years and over with hip fracture. The total number of studies included in the review was 44, which analyzed 26, subjects Older people with hip fracture presented an inadequate nutrient intake for their requirements, which caused deterioration in their already compromised nutritional status.
The prevalence of malnutrition was approximately The participants had prediabetes, and they were either men with obesity or overweight or women who had undergone menopause. Those who took 13 g of flaxseed had lower glucose and insulin levels and improved insulin sensitivity. A study on rats, published in , suggested that compounds found in flaxseed may help reduce the incidence of type 1 diabetes and delay the onset of type 2 diabetes in humans, but more studies are needed.
In , researchers published results of a study in which 99 people with prediabetes were given 40 g, 20 g, or no flaxseed and no placebo each day for 12 weeks. The results indicated that consuming flaxseed powder every day may reduce blood pressure in people with prediabetes, but it does not improve levels of blood sugar and insulin resistance.
Flaxseed is rich in both soluble fiber, which dissolves in water, and insoluble fiber, which does not dissolve in water. Insoluble fiber remains in the intestinal tract.
It absorbs water and adds bulk to the digestive tract. This helps keep movement through the gut regular. Consuming it with too little water can make constipation worse and possibly lead to an intestinal blockage.
Too much flaxseed or flaxseed oil can cause diarrhea. Flaxseed has long been used in Ayurvedic medicine for health promotion, prevention, and a range of conditions, many to do with skin health. A small study published in suggests that consuming flaxseed oil may help reduce skin sensitivity and roughness and improve skin hydration.
Studies have found that the lignans in flaxseed may help protect against radiation. Scientists gave dietary lignans in flaxseed to mice with lung problems caused by radiation. The mice that consumed the compounds derived from flaxseed had less inflammation , injury, and fibrosis, and a better survival rate that those that did not.
The researchers suggested that in the future, lignans from flaxseed may be useful for treating lung problems associated with radiation due to accidental exposure or radiation therapy.
Flaxseed is an excellent source of fiber, lignans, and of linoleic and alpha-linolenic acid ALA , two omega-3 fatty acids that are essential for human health. The USDA also note that flaxseed contains phytosterols. In every g of flaxseed, there are Lignans are also present in large amounts.
Lignans are a type of phytoestrogen. Phytoestrogens are estrogen-like chemical compounds with antioxidant qualities. They can reduce levels of free radicals in the body. Flaxseed is considered a good source of lignans, containing 0. Lignans may help protect against cardiovascular disease and a range of chronic conditions, if consumed for life as part of a healthful diet and lifestyle. However, more research is needed to confirm the exact role they can play.
Omega-3 fatty acids are thought to be beneficial for the heart. They can only be obtained by eating the right foods, as the human body does not produce them.
Flaxseeds should be consumed in ground form, as whole flaxseeds can pass through the digestive tract undigested. Too much flaxseed can lead to:. Raw and unripe flaxseeds are not suitable for consumption, as they may be toxic. Flaxseed should always be consumed with plenty of fluid. During pregnancy, women are advised not to consume it, because the phytoestrogens it contains could have an adverse effect.
It may not be suitable while breastfeeding. There is also a chance that the phytoestrogens in flaxseed may interfere with the action of birth control pills or hormone therapy. The USDA notes that up to 12 percent flaxseed is safe to use in food. It is not yet clear whether flaxseed does help control diabetes.
Anyone who is taking medication for diabetes should check with their doctor before introducing flax seed in your diet, in case an interaction occurs. Omega-3 fatty acids can increase the risk of bleeding, if used with blood thinners, such as warfarin Coumadin. Omega-3 supplements or flaxseed products and blood thinners should be used only after discussing with a health professional.
As with any herb or supplement, care must be taken when consuming large amounts. Flaxseed in its natural form is preferable to taking flaxseed as a supplement.
Supplements are not monitored Anyone who is considering taking it as an alternative or complementary therapy should first speak to their doctor. There is a selection of flaxseed products available for purchase online.
