Although it's crucial to
emphasise that fish isn't a cancer cure in and of itself, fish and fish-based
products can help prevent and treat cancer in a number of ways. Nonetheless,
certain characteristics of fish can be advantageous when incorporated into a
nutritious diet, either as part of a cancer prevention plan or during
treatment.
Fish can aid in the treatment of cancer in the following ways:
1. EPA and DHA, or omega-3 fatty acids
Omega-3 fatty acids are abundant in fish, particularly fatty fish like herring, sardines, mackerel, and salmon. These have been investigated because they may:
2. Decrease inflammation: Omega-3 fatty acids can aid in lowering inflammation, which is a major contributor to the onset and spread of numerous malignancies.
3.
Immunity: The body may be able to combat cancer cells more effectively if
omega-3 fatty acids are able to boost immune cell activity.
4. Enhance the efficiency of cancer therapies: According to some research,
omega-3 fatty acids may lessen treatment-related side effects such muscular
atrophy and cachexia, as well as increase the effectiveness of some cancer
treatments like chemotherapy. Research indicates that the proliferation of
cancer cells may be inhibited by omega-3 fatty acids. This is especially true
for cancers such as breast, prostate, and colon cancer.
5. Excellent Protein
When receiving cancer treatment, especially if a patient is receiving
chemotherapy or radiation therapy, fish is an excellent, easily digestible
source of protein. Nausea, exhaustion, and appetite loss are common side
effects of cancer therapies, making it challenging to keep a balanced
diet high-quality fish protein can be beneficial.
6. Preserve muscle mass: Fish is a great choice for people who might have
trouble consuming other foods high in protein, and protein is crucial for
preserving muscle mass and strength throughout therapy.
7. Support healing and recovery: Protein is essential for wound healing, immune
system maintenance, and general recuperation.
8. Vitamin D:
Vitamin D is found in fatty fish, such as mackerel, salmon, and tuna. According
to research, having enough vitamin D may help prevent cancer, especially colon,
prostate, and breast cancer. Immune system function, bone health (particularly
during cancer treatments that may weaken bones), and general health all depend
on vitamin D.
9. Bioactive Substances
Other bioactive substances like selenium and astaxanthin, an antioxidant present in salmon and other fish, are also present in some fish species, particularly fatty fish. Although additional research is required to completely grasp their involvement, many chemicals have been examined for their potential anticancer properties. Low in Saturated Fats Fish, especially those that are lean, are often Compared to red meats, fish—especially lean fish—generally have fewer saturated fats. A lower risk of some cancers, especially colorectal and colon cancer, has been linked to a diet lower in saturated fats.
Things to Think About
Although eating fish can help with cancer therapy, it's vital to keep the
following in mind:
Contaminants and Mercury: High quantities of mercury in some large fish, such
as swordfish, tuna, and shark, can be dangerous, particularly for those with
compromised immune systems.
Mercury
and Contaminants: High mercury concentrations, which can be hazardous,
particularly for those with compromised immune systems, can be found in some
large fish, such as swordfish, tuna, and shark. Fish with reduced mercury
levels, such as trout, sardines, and salmon, should be prioritized.
Dietary restrictions or allergies: Some people may choose plant-based diets or
have fish allergies. Plant-based omega-3 sources, such as flaxseeds, chia
seeds, or algal supplements, may be substitutes in these situations.
The following are cancer-specific diets: Dietary guidelines can change based on
the type of cancer and the treatment being administered. For instance, changes
in food texture may be necessary to address swallowing difficulties in cases of
head and neck cancer, or easy-to-digest meals may be given preference in
situations of gastrointestinal cancer.
Final Thoughts
Because it provides vital nutrients including protein, vitamin D, and omega-3
fatty acids—all of which can help the body during treatment—fish can be a
significant component of a cancer patient's balanced diet. However, cancer
treatment regimens should always be customised to meet the needs of each
patient, therefore seeking individualised guidance from a healthcare
professional or dietitian is crucial.
It's a good idea to talk to your oncologist or a qualified dietitian about your
nutrition if you're receiving cancer treatment or are thinking about making
dietary adjustments. They can advise you on the foods that will best support
your treatment objectives and overall health.
