Surprisingly, Oat milk can be stored for 6 months. Unopened oat milk cans or cartons can be kept in normal dry and cool places.

Once opened, oat milk needs refrigerator storage by the end of 2 days. The bottom line is, Oat Milk is more durable and usable with longer shelf life than whole milk. Note: Always check the manufacture and expiry dates on the milk pack before purchase or consumption.

3. Vitamins And Minerals

Whole milk provides 13 essential nutrients to your body, whereas oat milk has just 5 in it. Whole milk has naturally nutrient-rich profile without added supplements. Calcium and vitamin D are two abundant nutrients found in whole milk.

Oat milk is externally fortified with nutrients. It also has more carbohydrates than whole milk per serving. For calorie concerns, oat milk is low in calories than whole milk. According to 2020 USDA and NIH data, 100 ml of whole milk contains 61 calories. The same quantity of oat milk has only 38 calories. Therefore, oat milk is better for weight loss.

Whole milk offers more vitamins and minerals and serves as the main protein source. But, at the same time, it is heavier for digestion due to excess cholesterol and fat.

Environmental Impact of Whole Milk?

Whole milk is a widely consumed dairy-based beverage worldwide. But, not to forget it is sourced from cows which creates planet issues. Manufacturing whole milk comes with an environmental price. These are some serious effects of whole milk on the environment:

1. Depletion of water resources

Studies have proved that milk is the most water-intensive and exhaustive industry. As of 2018 per gallon of milk requires a whooping 628 gallons of water. 35- 50 gallons of water are required for cattle consumption. The volume of water required for whole milk exceeds the combined water requirements of crops, fruits, and vegetables.

2. Large-scale deforestation

Cattle grazing is entirely dependent on our natural land. Deforestation has vanished mammoth hectares of forests and natural beauty from our planet. The cleared and tree-free rainforests have become cattle habitats.

A report from The World Wildlife Fund states that livestock feeding is met by 80% of the world’s soy, for which long belts of the amazon rainforest, The Atlantic Forest, and other significant habitats are being transformed into soy hotspots.

3. Greenhouse effect

The growing effects of climate change due to ozone layer depletion are alarming. One of the primary catalysts of this phenomenon is the cattle population. They contribute to 14.5% of total greenhouse gas production worldwide in the form of methane. Methane is produced within the cow’s belly.

The greens they eat produce methane through the process of microbial fermentation. Their burps and flatulence emit methane. Methane warms up the planet much more aggressively and rapidly than carbon dioxide. In contrary to any plant-based substitute, one cup of cow’s milk emits 1.3 pounds of greenhouse gases.

4. Animal Cruelty

Raising cattle to obtain milk is a form of animal exploitation. Cows are genetically modified to produce better-quality milk. It’s a fact that cows can only produce milk with repeated pregnancies.

Thus, they undergo an artificial calving period over consecutive years several times to produce more gallons of milk per cow. Subsequently, they are sold to beef companies, after expiring their milk production limit.

Environmental Impact of Oat Milk?

Oat milk wins the second people’s choice vegan milk award after almond milk. It is free from animal cruelty as it’s purely plant-based. Let’s see whether oat milk is better than whole milk from the lens of environmental concern.

Oat milk is more water efficient. Oat milk is produced from “Avena sativa,” the oat crop which is cultivated in the winter season and requires low water levels to grow ideally. These crops harness rainwater eight times more than blue water bodies. Therefore, they contribute to the green and conservative vision. One gallon of oat milk needs approx. 48 gallons of water for production and 0.25 gallon for liquidation.

2. Sustainable Land Utilisation

Oat crops have short sow and yielding periods, usually lasting for 4 months. It is compatible with all soil types and weather. This is why oats are grown almost everywhere with ease. Oat crops promote crop rotation by making room for other crops after they are cut off. It helps in soil renewal and enhances land fertility.

3. Greenhouse Effect

In comparison to whole milk, oat milk is a much greener milk type which only a 0.4 carbon footprint. It has the lowest global warming contribution, except for one drawback. The leftover pulp of oats is dumped into pits, which produces methane- a highly potent greenhouse gas. Positively, it can be reused for cattle feeding.

4. High chemical reactions

Oat cultivation involves the utilization of huge amounts of harmful synthetic pesticides and fertilizers. These chemicals absorb into the soil, travel to groundwater, and create havoc in marine life. It can be lethal for aquatic mammals. Luckily, there are organic oat milk brands which are manufactured with natural manures.

Oat Milk vs Whole Milk | Which Is More Sustainable?

Evidently, Oat milk stands as a clear winner. Oat milk is eco-friendly and sustainable as compared to whole milk on all environmental aspects. It mitigates every negative effect of whole milk production on land use, water conservation, and escalating global warming rate.

The minimal oat crop cons are manageable to large extent. Relatively, oat milk demands fewer gallons of blue water, can be grown in any soil with further land rejuvenation, and produces the least carbon or methane emissions in the atmosphere. It is completely vegan-friendly and avoids merciless animal exploitation.

In long term, Whole milk poses serious threats to wildlife, nature, and living beings as a whole. If you have resources and access, switching to oat milk will be a step towards a sustainable future.
