Keto Diet and Recipes

Role Of Spices In Ketogenic Diet

Indian food is incomplete without use of spices. A single dish has so many variants in different parts of India because of the different spices used. Any recipe would be tasteless without spices. Ketogenic diet due to its unique combination of nutrients i.e. high fat, low carbohydrate and normal protein diet needs to be flavored with different spices in order to increase compliance. Having said that, taste is just one aspect of spices and there are many other important.

Spices are also known as functional foods which means a food containing health-giving additives. Today we are going to discuss the role of spices in neurological disorders. Spices have been used in cooking to add flavor and color to the food. A spice is a dried seed, fruit, root, bark, or flower of a plant. The use of spices has shaped a large part of the world’s history. In fact the Spice Wars was fought for over 200 years between the European powers in the 15th and 17the century!

In ancient times, many spices were used as medicines for treating several diseases such as rheumatism, body ache, intestinal worms, diarrhea, intermittent fevers, hepatic diseases, urinary discharges, dyspepsia, inflammation, constipation, and dental diseases. What was the active component in spices and how they exerted their action remained obscure to ancient people. Modern molecular tools have shown that spices have active components, called nutraceuticals that contribute to the plethora of properties. (Kannappan et al)

Phytochemicals generally are regarded as research compounds rather than essential nutrients because proof of their possible health effects has not been established. Phytochemicals under research can be classified into major categories, such as carotenoids and polyphenols, which include phenolic acids, flavonoids, and stilbenes/lignans. Elizabeth I. Opara et al, 2014.

Table 1 :- Type of Polyphenols

Table 2:- Mean content (mg per 100 g of food) of flavonoids, phenolic acids, lignans and stilbenes in the main food sources of these polyphenol classes. L. Valdés et al.2015

Polyphenols and polyphenol rich foods especially fruits, vegetables and green tea, are widely

known for their antioxidant properties. However, they exert other biological effects (anti-inflammatory, anti-cancer and neuro-protective)

Culinary herbs and spices have also been shown to possess these properties

Considering the bioactive properties that culinary herbs and spices possess, the need to determine

their intake is being acknowledged. Intake data are available for particular groups/populations.

However, the relatively low intake levels of culinary herbs and spices do not necessarily mean that they are of little value as their high polyphenol content, and thus ultimately the potential biological impact of this content, cannot be ignored.

Culinary herb and spice intake studies.
Study Intake Data
Pellegrini et al. Determined daily intake of spices0.4 (1.3) g (3D-WR); 3.2 (2.7) g (FFQ)
using 3 day weighed food record (3D-WR) and food
frequency questionnaire (FFQ). For the 3D-WR median
data were obtained. For the FFQ, interquartile range
data were obtained. n = 285;
Subjects: men (n = 159) and women (n = 126);
Country of study: Italy
Carlsen et al. Determined herb and spice intakeMedian estimates of total herb and spice
using a FFQ and 2–4 weeks later 28 days recording ofconsumption: 2.7 g/person/day (range 0.19–45.0;
herb and spice consumption (HSR). n = 146;Interquartile range 4.4) from the FFQ;

daily polyphenol intake using 24 h dietary records every
2 months from 1995–1996 and the Phenol-Explorer
database. Mean intake data obtained. n = 4942;
Subjects: men (n = 2596) and women (n = 2346);
Country of study: France

Form of spices:-

Polyphenols are found in numerous plant derived foods including herbs and spices, which, especially in their dried forms, generally contain relatively high levels of polyphenols compared to other polyphenol rich foods including broccoli, dark chocolate, red, blue and purple berries, grape and onion.

Combination of spices: –

Recent studies on the antagonistic and synergistic effects of combinations of individual polyphenols or combinations containing polyphenol rich foods.

Epigallocatechin gallate
(EGCG)(found in green tea) and curcumin (turmeric)
Synergistically cytotoxic to MDA-MB-231 estrogen
receptor α (ERα) human breast cancer cells in vitro when compared to effects of the individual polyphenols.
EGCG + curcumin also synergistically inhibited tumor
growth within female athymic nude mice implanted with MDA-MB-231 estrogen receptor (ERα) human breast cancer cells compared to individual polyphenols.
Proposed mechanism of action: Cell cycle arrest and
decrease in the expression of vascular endothelial growth factor receptor in tumor may play a role.
et al.
Curcumin and resveratrolSynergistic inhibition of growth of p53 positive and p53
negative human colorectal cancer HCT116 cells in vitro
when compared to effects of the individual polyphenols.
Curcumin and resveratrol combination also synergistically inhibited tumor growth within severe combined immunodeficient female mice implanted with HCT-116 cells.
Proposed mechanism of action: Decrease in proliferation and induction of apoptosis, decreased NF-κB activity,inhibition of activation of epidermal growth factor receptor.
et al.
Carnosic acid
and curcumin
Combinations (at levels shown to be non-cytotoxic to
normal human fibroblasts or human peripheral blood
mononuclear cells) inhibited the growth of, and induced
apoptosis in, HL-60 and KG-1a human acute myeloid
leukemia cells.
Proposed mechanism of action: Apoptosis associated with activation of caspases 8, 9 and 3 and Bid (a proapoptotic protein) which is a member of the Bcl family. No other Bcl proteins shown to be affected. No evidence that oxidative stress was involved.
et al.
Polyphenol rich herbs
oregano, ajowan
(Trachyspermum ammi)
and Indian borage
(Plectranthus amboinicus)
Addition of oregano extract increased the radical
scavenging activity of ajowan and Indian borage extracts
et al.
Peppermint, rosemary,
sage, spearmint, thyme.
All herb extracts inhibited the growth of SW-480 human colorectal cancer cells. Combinations of these extracts herbs had additive, antagonistic and synergistic effects, which were based on the combinations and/or the concentrations of the herb extracts used in
the combinations.

Author Chris Kilham rightly said ‘You don’t have to do something exotic to enjoy the benefits of natural healing agents. So many things in your kitchen – common spices, common herbs and foods – have powerful healing agents as well’.

After reading this article we hope that you will use spices not only for its magical flavors but also because of its amazing health benefits
