Raspberries: Uses, Benefits, Side Effects By Dr. Rajeev Singh

By Dr Rajeev Singh +2 more

Introduction: 

Most of us have relished raspberry ice cream on a hot sunny day. Isn’t it astonishing to know that raspberries have several health benefits? It is believed that the Romans first cultivated raspberries in the fourth century. Raspberries are considered to be the first collected by the people of Troy from the foothills of Mt. Ida. This fruit is native to North Asia and Eastern Europe. Raspberry belongs to the family Rosaceae, and its scientific name is Rubus Idaeus, which means ‘bramble bush of Ida.’ It was thought that the Olympic Gods were looking for berries on Mt. Ida.1 Raspberry are a host of several nutrients. Let us look at some health benefits of raspberries.

Based on studies I came across, eating raspberries might result in changes in genes and blood substances related to the immune system and metabolism. These findings suggest that regularly consuming raspberries may affect our immune and metabolic pathways that might be beneficial for our health.

Potential Uses of Raspberries for Overall Health 

There are several raspberry fruit benefits. Some of the potential raspberry fruit uses are: 

1. Potential use of raspberries for heart and blood pressure 

Raspberries may possess antioxidant activity, which may be beneficial for heart diseases. A study by Mullen et al. in 2002 showed that raspberries might be an antioxidant because of bioactive compounds like ellagitannins, anthocyanins and vitamin C. Anthocyanins may improve the function of endothelial cells (cells that regulate blood flow in the heart). Additionally, raspberries may also regulate blood pressure.1,3 However, more studies are required to check if raspberries may protect the heart. Therefore, you must consult your doctor if you have any symptoms of heart disease. 

2. Potential use of raspberries for diabetes 

A study by Jayaprakasam et al. in 2005 showed that the bioactive compound anthocyanins in raspberries might stimulate insulin secretion and reduce the risk of type 2 diabetes. Another bioactive compound, cyanidin-3-glucoside, may reduce the blood sugar levels.1,4 However, more research is required to check if raspberries may be beneficial for diabetes. You must check your blood sugar levels regularly and consult your doctor in case of abnormal blood sugar levels. 

3. Potential use of raspberries for weight management 

A study by Park et al. in 2010 showed that ketones in raspberry might benefit weight loss. The ketones may break down the lipids or the fats (lipolysis). It may also cause fatty acid oxidation, which may help with weight loss. It may also regulate the secretion of adiponectin, a hormone that breaks down fatty acids.1,5 However, more research is required to check if raspberry may benefit weight management. You must consult your nutritionist before making any changes in your diet. 

4. Potential use of raspberries for cancer 

A study by Bowen-Forbes et al. in 2010 showed that raspberries might inhibit cancer cell growth due to bioactive compounds like anthocyanins. Polyphenols in raspberries may reduce the risk of colon and intestine cancer. Ellagitannins and anthocyanins may reduce the risk of cancer due to their antioxidant property. They may deactivate the harmful free radicals (molecules that harm the body).1,6 However, more research is yet to be done to check if raspberries may be used for cancer. Cancer is a serious disease; therefore, you must take an informed consultation and proper medications as advised instead of self-medicating. 

5. Potential use of raspberries for Alzheimer’s disease 

Alzheimer’s disease may be characterised by disturbed insulin functioning and increased oxidative stress and inflammation. Raspberries may contain bioactive compounds like polyphenols which may regulate insulin levels, reduce inflammation and reduce oxidative stress. These three factors may cause Alzheimer’s disease. In addition, raspberry fruit may decrease deposition of amyloid-β protein, which may be beneficial in reducing the risk of Alzheimer’s disease.1,7 However, more studies are required to check whether raspberry may benefit Alzheimer’s disease. Therefore, you must consult your doctor if you have any symptoms of Alzheimer’s disease and never self-medicate. 

6. Potential use of raspberries for skin 

A study by Wang et al. in 2018 showed that compounds like cyanidin and ellagic acid might help to protect the skin from UV rays. It may reduce skin cell death, thickening, wrinkles, dryness, tanning and redness of the skin.8 However, more studies are required to check if there are raspberries benefits for skin. You must consult your doctor if you see any abnormality in your skin. 

7. Potential use of raspberries to lower lipid levels 

A study by Ash et al. in 2011 showed that α-linoleic acid in raspberry might be beneficial to lower triglyceride levels in the body. A condition called dyslipidemia is an excess of triglycerides, which are harmful fats present in the body. Therefore, raspberries may also be beneficial for dyslipidemia.9 However, more studies are required to check if raspberries can reduce the levels of triglycerides in the body. 

8. Potential use of raspberries for hair growth 

A study by Harada et al. in 2007 showed that raspberry ketones might be beneficial for hair growth in alopecia patients. The raspberry ketones may increase blood flow in the scalp and help in hair growth.10 However, more studies are yet to be done to check the raspberries benefits for hair Therefore, you must get proper treatment if you have conditions that cause hair loss like alopecia instead of self-medicating. 

Though studies show the benefits of raspberries in various conditions, these are insufficient, and there is a need for further studies to establish the true extent of the benefits of raspberries on human health. 

In light of what I have observed, raspberries are a great source of dietary fibre. This might play a crucial role in promoting healthy digestion and managing constipation.
